Polymyositis is a disease that causes the body’s muscles to become irritated and inflamed. It can affect the muscles all over the body. The muscles gradually begin to break down and weaken, making everyday movements difficult. This disease falls into a category known as inflammatory myopathies.
Contents
Polymyositis Unknown Causation
The causes of polymyositis are currently unknown. However, experts believe it could be associated with or triggered by a virus or an autoimmune reaction. An autoimmune response is when the body attacks itself along with the body’s tissues. It’s seen in individuals ages 31 to 60 and is rarely seen in individuals younger than 18. In some instances, medication can lead to an allergic reaction/response that causes muscle irritation and damage. But in most cases, healthcare experts are not able to find the exact cause.
Symptoms
The condition can affect the muscles all over the body. Physical activities like walking, getting up from a chair, or lifting objects can become difficult to perform. It can also affect the muscles that allow for eating and breathing. The muscles at the center of the body tend to be affected the most. Common symptoms include:
Muscle pain.
Muscle stiffness.
Muscle weakness, specifically in the abdomen, shoulders, upper arms, and hips.
Joint pain and stiffness.
Breathing problems.
Problems swallowing.
Abnormal weight loss can become an issue if there are problems with swallowing.
Irregular heart rhythms if the heart muscle/myocardium becomes inflamed.
Individuals may notice they have trouble climbing stairs or lifting their arms.
The inflammation can worsen, causing pain and weakness that affects the wrists, lower arms, and ankles.
Diagnosis
Diagnosis begins with the individual’s medical history, family medical history if necessary, and a physical examination. The examination includes seeing and feeling the strength of the muscles. Tests will be required that include:
Blood Tests
Blood tests allow the doctor to see if there are signs of muscle inflammation.
They also show if there are abnormal proteins that form in autoimmune diseases.
Electromyogram EMG
This test can be used to find abnormal electrical activity in the affected muscles.
MRI
Magnets and computer graphic imagery are used to help the doctor inspect for inflammation in the body.
Muscle Biopsy
A small piece of muscle tissue is removed to be analyzed with a microscope.
Treatment
Treatment depends on how severe the condition is,individual symptoms, age, and overall health. Currently, there is no cure for polymyositis, but symptoms can be managed. Individuals are recommended to utilize more than one type of treatment because the treatment plan may also need to be changed as treatment progresses. Treatments include:
Anti-inflammatory Medication
Steroid medication can help manage the disease and reduce symptoms, and corticosteroids can help ease inflammation in the body. The symptoms improve within 4 to 6 weeks, and a healthcare provider can lower the dosage after the symptoms decrease to reduce and ease any side effects.
Immunosuppressive Medication
These medications block or slow down the body’s immune system responses.
Talk with a doctor about the risks, benefits, and side effects of all medications.
Chiropractic and Physical therapy
Chiropractic treatment and physical therapy can help:
Aligning the spine to provide optimal nerve energy and blood circulation.
Therapeutic massage to stimulate and keep the muscles loose.
Specific exercises to help stretch and strengthen the muscles.
These can help keep the muscles from shrinking.
Heat therapy and Rest
Heat therapy and allowing the body to rest thoroughly can help decrease pain symptoms.
Special Braces
Body, hip, and leg braces can help support the muscles and help with mobility.
Complications
Polymyositis left untreated can lead to severe complications. The muscles become weaker, increasing the risk of falling and limiting daily activities.
If the chest muscles are affected, there could be problems with breathing that can lead to respiratory failure.
If the digestive tract is affected, malnutrition and unintentional weight loss can result.
Polymyositis poorly managed well can cause severe disability.
Body Composition
Nutrition and Muscle Growth
Protein
Protein is the foundation for gaining muscle.
This essential component is for all of the body’s daily functions.
It is essential to balance protein increase with overall diet.
Carbs should be a daily element of nutritional intake because they are the primary component.
Acquiring energy
Preventing muscle weakness and degradation
Consuming Carbs
Understanding how accurate results only happen when both sides work together.
Healthy consumption of protein and carbohydrates can help muscle growth and sustain optimal health for all body types.

There are various causes for achiness or soreness under the shoulder blades. The shoulder blade is the triangular bone that forms the back of the shoulder. This pain can range from dull, sharp, burning, or a combination between the spine and shoulder blade to tender or achy across the shoulder or upper back. Pain can spread from another body part or structure, like the neck or spine. Inflammation from injury or overuse is noticeable at onset or gradually after engaging in physical activity and can limit arm movements and interfere with regular activities.
Contents
Improper Posture
Improper poster combined with prolonged sitting can cause the spine to develop structural changes that cause pain under the shoulder blade. Habits that lead to poor posture include:
Hunching the back.
Tilting the head down – looking at the phone.
Leaning to one side while sitting, working.
Poor posture habits cause the muscles to weaken, placing added pressure on the spinal discs, muscles, and ligaments. This body imbalance can contribute to upper back and shoulder pain.
Lifting Improperly
Lifting weight above the head and not using the proper technique can leave the upper back and shoulders vulnerable to injury. Lifting an object that is too heavy or is held in an awkward way causing the spine to be misaligned creates added pressure in the upper back. This can strain the muscles, sprain ligaments, injure the shoulder joint, or spine, which can cause spreading pain under and/or near the shoulder blade.
Repetitive Overuse Injury
Painting, moving furniture, or participating in sports are activities that can overwork the upper back muscles and shoulders. Overuse can lead to muscle strains and ligament sprains. This can cause pain in the upper back between the shoulder blade and the spine. Scapulothoracic bursitis, also known as snapping scapula syndrome, is when the bursa between the shoulder blade/scapula and the thoracic spine becomes inflamed, causing pain.
Cervical Herniated Disc
A herniated disc in the cervical spine/neck happens when a disc’s outer layer/annulus fibrosus tears and the inner layer/nucleus pulposus starts to leak outward. This can cause pain and cause the nearby nerve roots to become inflamed, causing pain to run down into the shoulder, arm, and/or hand. A disc herniation in the lower part of the neck usually radiates pain into or near the shoulder blade area. Although less common, a herniation in the upper back can cause pain around or near the shoulder blade.
Dislocated Rib
An accident or fall could cause a rib to become dislocated or misaligned after repetitive/overuse strain or reaching too far overhead. Sharp pain near the shoulder blade can result from this activity and can sometimes make it challenging to take a deep breath.
Compression Fracture
A compression fracture occurs when a vertebral bone in the upper back weakens and compresses. This can lead to back pain with a heightened sensitivity across the shoulder area. The pain usually decreases with rest. Compression fractures are commonly caused by osteoporosis in older individuals. Any back or shoulder pain that persists for weeks or interferes with regular activities should be evaluated by a doctor or chiropractor. If the pain is severe or accompanied by symptoms like headache, tingling, weakness, or nausea, individuals are recommended to seek medical attention.
Body Composition
Carbohydrate/Carb Loading
Carbohydrates are macronutrients that serve a critical function in the body, as they are the body’s primary energy source. The body breaks down carbohydrates into sugar that enters the bloodstream and is stored for energy use in the muscles and liver as glycogen. The muscles only store small quantities of glycogen. And when engaging in physical activity or exercise, the energy stores get used up.
Carbohydrate loading can raise glycogen stores in the muscles from 25 to 100 percent of their average amount in men. Women have shown mixed results in studies on carbohydrate loading. Women need to take in more calories than men when carb-loading to experience the same gains in glycogen. Reasons to carb load are either to:
Build-up stores of glycogen so an individual can use the extra energy storage to help improve endurance.
Fill the muscles with glycogen to bring water into the muscles to help gain mass and tone.

Kettlebell training for the back muscles and back pain prevention can be part of a recommended treatment plan. When experiencing low back pain, many sports medicine experts recommend kettlebell exercise to strengthen the core and posterior chain. However, if not used correctly, kettlebell exercises can worsen back pain.
Contents
Kettlebell
They are made of cast iron or steel and are named for resembling a tea kettle with an oversized handle. They can be used in one and two-handed movements.
Exercises and Movements for Back Pain
For individuals that are not experiencing back pain, kettlebell training can be excellent for maintenance and injury prevention. They strengthen the core and back muscles.
The kettlebell swing is an essential exercise and is one of the most important exercises when dealing with back pain issues.
A kettlebell is placed on the floor about 12 inches in front while standing with the feet a little wider than hip-distance.
The hips become the hinge.
Extend the arms down to the bell and grip it.
Begin swinging it up and down through the legs and then upward and outward to chest level.
The shoulders are to stay relaxed.
The hips are used to thrust and create momentum to swing the kettlebell.
Keep the spine neutral throughout the exercise to prevent injury.
The arms are to hold the bell only.
Don’t swing with the arms or shoulders, but push through with the hips.
The exercise can be swung up over the head but is not recommended for those with back pain.
Benefits
They are portable and don’t require a lot of space.
With kettlebells, an individual can train more easily than with barbells.
Kettlebell workouts provide strength training and cardiovascular fitness.
Once the proper technique is learned, individuals can set up a regular regimen at home.
Proper Form and Mistakes
Proper form is crucial. The primary movement most individuals have difficulty with is getting the proper hinging motion at the hip. Most individuals flex at the lower back and place increased pressure on the discs. Proper hip hinge motion means:
Keeping the low back straight
Flexing at the hip
Pushing back out with the buttocks when performing the swing motion.
When done correctly, an individual should be able to stop at any stage and hold that position.
Posture Form Tips
Form issues with kettlebells include:
Hip Hinge
When picking up the kettlebell, remember to hip hinge instead of squatting to maintain the back in a neutral position.
Drive the hips back in the same way when sitting down on a low chair.
Arching the back
If the pelvis is tilted too far forward, the back arches a lot.
This can narrow where the nerves leave the spine in the low back.
Keep the abdominals tight to prevent the pelvis from tilting forward.
Using the incorrect weight can also cause problems; this could be going too heavy or too light.
Too heavy increases the risk of straining the body and back.
A kettlebell that is too light does not provide the correct resistance to strengthen the muscles.
Another common mistake is overtraining. Specifically, individuals over 50 whose bodies don’t recover as quickly.
Individuals over 50 are recommended to spread out the workout days with more than one rest day.
Common Injuries
Proper training before working with kettlebells is highly recommended, especially for those already dealing with back pain. Individuals are encouraged to work with a physical therapist, sports chiropractor, or personal trainer who can teach proper techniques and specific exercises, observe the individual’s process, and make corrections. Improper technique can lead to:
Muscle strains.
Muscle spasms.
Compressed or pinched nerves.
Added stress to pre-existing low back conditions.
Impact injuries to the wrist and forearm.
Body Composition
Exercise Ball Pikes
Exercise ball pikes are an advanced total body workout. Muscle groups worked out include:
Deep abdominals
Hip abductors
Quadriceps
Deltoids
Scapula stabilizers
Pectoralis major/minor
To do the exercise:
Start in a pushup position with the arms on the floor in front.
Lift the legs, so the tops of the feet rest on the exercise/stability ball.
Knees should be bent to start the movement.
Extend the legs out as straight as possible.
Hold the position for a few seconds.
Return to the starting position.

Neck crepitus is a grinding sound that comes from moving or rotating the neck. Usually, it is not something to worry about, as the body is a sound system that generates various noises. For example, when hungry, the stomach rumbles. After digestion, the body releases the gasses through a burp. The bones can also generate neck cracking or popping sounds with regular movements. This unusual sensation is known as crepitus.
Contents
Crepitus
Crepitus or crepitation is a scientific term that describes joint movements sounds. Sounds can include:
Popping
Cracking
Snapping
Grinding
However, crepitus can happen in any moveable joints in the body. An example could be a neck cracking or popping sound when looking over the shoulder.
Why the Neck So Susceptible
The cervical spine consists of seven segments, and each segment has multiple joints that interact with the segments above and below it. The cervical spine is a flexible system that protects the neurologic structures while maintaining head and neck stability. This flexibility and the multiple joints at each level can wear down, leading to arthritis and neck crepitus.
Other Symptoms
Neck crepitus can present without other symptoms. But it can also be associated with other severe symptoms that include:
Neck pain
Instability
Weakness
Numbness
Diminished manual dexterity
Difficulty walking
Risk Increases With Age
Neck crepitus can present at any age; however, the risk increases as the body ages. Some individuals may have neck crepitus symptoms more often. For example, the neck cracking or popping sounds could present just a few times a month. However, other individuals could have cracking, popping sounds daily or even throughout the day. Neck crepitus can increase or decrease in frequency. Symptoms could present for several days before the sensations stop entirely.
Possible Causes
Neck crepitus can have various causes, and multiple factors can also overlap to generate these sensations.
Articular Pressure Changes
Natural lubricating lining and fluid are found within the body’s joints. Small gas bubbles can form within the synovial joints, including the facet joints. When the bubbles collapse, they are released, creating cracking noises in the joints. The sounds can happen with regular everyday movements. This also occurs when a chiropractor or physical therapist performs spinal manipulations.
Tendon or Ligament Movement
Tendons are the tissue that connects the muscles to the bones, and Ligaments connect the bones. A tendon in motion can also make noises when sliding around a bone or over another tendon or ligament. The cracking can be caused by tight tissues and muscles from aging or muscles that have become weak/deconditioned.
Bones Grinding
Osteoarthritis, known as spondylosis in the spine, can cause the facet joints that connect the vertebrae to degenerate. The protective cartilage wears down, and the vertebral bones start to rub against each other. This can produce a grinding noise. However, the grinding can result from disc degeneration, which reduces the cushioning between the vertebrae.
When to Consult A Physician
If neck crepitus presents without other symptoms, it’s usually not serious. When neck crepitus presents with other symptoms, it is recommended to contact a doctor. These symptoms include:
If pain spreads out and runs down the arm or there is difficulty completing fine motor tasks like writing your name or getting dressed, consult a doctor. These symptoms can be caused by spinal cord or nerve root compression. Sometimes, neck crepitus can show up after a different health issue. For example, if an individual notices neck sounds weeks after cervical spine surgery, the spine surgeon can determine if the two are connected. A recent fall or car accident could also cause symptoms to present. If the crepitus presents almost every time with joint movement, there could be compromised joint function.
Treatment and Prevention
There are various treatment options for neck crepitus. It is recommended to start with conservative treatment like physical therapy and chiropractic pain management. Imaging scans are necessary to see if there are signs of compression on the spinal cord or nerves. Treatment objectives are to remove the pressure from the neural structures and restore the spine’s stability. Cervical traction is another form of treatment. Consult a physician, spine specialist, or chiropractor to properly diagnose the issues, figure out what is going on, and develop a personalized treatment plan if necessary.
Body Composition
Sugar Replacements
Sugar substitutes can help with weight control and diabetes by allowing individuals to eat sweets without raising blood sugar levels. Sugar replacements are additives that add sweetness to food without the calories of sugar. Some sugar substitutes are synthetically made, while others are natural. Sugar replacements include:
Sucralose
This artificial sweetener comes from sucrose and contains no calories. It is highly sweeter than sugar and can be found in grocery stores.
Fructose
This sweetener comes in crystalline form or high-fructose corn syrup, which is often used for baking. Fructose is sweeter than sugar and has been linked to early diabetes.
Stevia
This sweetener is extracted from the stevia rebaudiana plant species. It is calorie-free and can help manage and improve cholesterol levels.
Aspartame
Only a tiny amount is necessary, as this artificial sweetener is 200 times sweeter than sugar. It contains four calories per gram.
Aspartame has been associated with cancer, dementia, and depression. But research has not found a direct correlation, and currently, recommended amounts are safe to consume.

Compartment syndrome is a condition that causes pressure within a group of muscles to build up to dangerous levels. This pressure build-up begins to decrease blood flow, not allowing proper circulation, nutrients, and oxygen from getting to the nerves and muscle cells. The syndrome can be acute or chronic, and surgery can be required. Acute compartment syndrome is considered a medical emergency, usually caused by a severe injury and requires immediate treatment; otherwise, it can lead to permanent muscle damage. Chronic compartment syndrome or exertional compartment syndrome is usually not a medical emergency and is often caused by physical exertion.
The fascia does not stretch or expand because its job is to keep the tissues in place. If compartmental pressure builds up, swelling and bleeding may occur. When the tissues don’t have enough blood to provide the proper amount of oxygen and nutrients, the tissues begin to die, leading to permanent damage. Because the fascia does not stretch if there is swelling or bleeding within a compartment, this increases pressure on the:
Capillaries
Nerves
Muscles in that compartment.
Blood circulation does not reach the compartment to supply oxygen and nutrients.
Nerve and muscle cells get damaged.
Compartment syndrome most often takes place in the lower leg’s anterior/front calf compartment.
However, it can also develop in other areas like the:
Legs
Arms
Hands
Feet
Buttocks
Acute
The typical symptom is pain, specifically when the muscle in the compartment is stretched.
The pain is more intense than the injury itself.
Flexing, contracting, or stretching the muscles increases the pain.
Tingling or burning sensations may present.
Muscle tightness or fullness sensation like bloating.
Numbness or paralysis are late symptoms that usually indicate severe to permanent tissue injury.
The acute syndrome develops after a severe injury, like an automobile accident or from a broken bone. Injuries and conditions that can cause acute compartment syndrome include:
Fractures
Muscle contusion/bruise that goes beyond just a bump. Two examples include a motorcycle falling on the rider’s leg or a football player getting hit in the leg intensely.
Constricting bandages – Casts and bandages that are too tight can cause the blockage of blood. If symptoms develop, remove or loosen any constricting bandages. If it is from a cast, contact the doctor immediately.
Anabolic steroids – Taking steroids is a possible factor in compartment syndrome.
Blood circulation restoration after a blockage.
When sleeping, a blood vessel can get blocked. Lying for a long time in a position that causes a limb to go to sleep, then shifting, moving, or getting up can contribute to the condition. This type of development can happen in individuals with neurological damage or who do not realize what is occurring. This can happen after intense intoxication with alcohol and/or drugs.
Surgical repair of a damaged blood vessel that was blocked can result in compartment swelling.
Permanent disability and tissue death can result unless the pressure is relieved.
Chronic Physical Exertion
The pain and swelling from the chronic condition are caused by vigorous physical activity/exercise. It most often occurs in the leg. Individuals that participate in activities with repetitive motions have an increased risk. Physical activities/sports include:
Running
Biking
Swimming
This is usually not dangerous and is often relieved by discontinuing the specific exercise/s or physical activity for a while. Symptoms include:
Pain during exercise.
Cramping during exercise.
Numbness
Moving the foot is difficult.
Muscle bulge can be seen.
Chiropractic Treatment
Leg pain should not be ignored for long as the problems could escalate into severe/dangerous territory. Chiropractic treatment is highly effective in the detection and treatment of leg pain. Chiropractors are experts in the neuromusculoskeletal system. Their expertise in promoting physical function applies to the whole body’s systems, including the:
Muscles
Bones
Ligaments
Nerves
Tendons
They are trained to diagnose and treat developing and chronic musculoskeletal problems and know when to seek specialized medical care when necessary.
Body Composition
Can’t Individuals Just Exercise More and Eat Whatever They Want?
No individuals cannot just exercise/move more and eat whatever they want if they are serious about losing excess weight. A healthy diet and exercise are essential parts of the formula for effective weight loss. One study shows that being aware of diet in quality and quantity overtakes just exercising when achieving and maintaining healthy body composition changes as a vital part of maintaining a healthy lifestyle. Evaluating the effects of diet, exercise, or a combination of both revealed that long-term success was most significant in the mix of diet and exercise. Individuals can exercise vigorously, but losing weight can be very difficult if they have unhealthy eating habits or cannot stick to a healthy diet. The individual can develop other health problems from an unhealthy diet.

Vehicle accidents are a leading cause of injury and death worldwide, with millions of crashes occurring annually. In 2023, the National Highway Traffic Safety Administration (NHTSA) reported approximately 6.1 million police-reported crashes in the United States alone, resulting in over 2.5 million injuries and 40,000 fatalities (NHTSA, 2024). Understanding the different types of vehicle accidents is critical for drivers, policymakers, and healthcare professionals to promote safer roads and effective injury prevention. This article explores the most common types of vehicle accidents, their causes, and their impacts on individuals and communities, while incorporating insights from recent research.
Common Types of Vehicle Accidents
1. Rear-End Collisions
Rear-end collisions occur when one vehicle strikes the back of another. These are among the most frequent types of accidents, often caused by distracted driving, tailgating, or sudden stops. According to the Insurance Institute for Highway Safety (IIHS), rear-end crashes accounted for 29% of all collisions in 2022 (IIHS, 2023). Common injuries include whiplash, neck strains, and soft tissue damage, which can lead to chronic pain if untreated (Mayo Clinic, 2025).
Causes:
Distracted driving (e.g., texting, eating)
Following too closely
Sudden braking or traffic slowdowns
Poor weather conditions, reducing visibility or traction
Prevention:
Maintain a safe following distance (e.g., the 3-second rule).
Use advanced driver-assistance systems (ADAS) like automatic emergency braking.
Stay focused and avoid distractions while driving.
2. Side-Impact Collisions (T-Bone)
Side-impact collisions, often called T-bone accidents, occur when the front of one vehicle strikes the side of another, typically at intersections. These crashes are particularly dangerous due to limited side protection in most vehicles. The NHTSA notes that side-impact crashes accounted for 24% of passenger vehicle occupant deaths in 2022 (NHTSA, 2024).
Causes:
Running red lights or stop signs
Failure to yield the right-of-way
Misjudging traffic signals or other vehicles’ movements
Poor visibility at intersections
Prevention:
Always check for oncoming traffic before entering intersections.
Use side-impact airbags and reinforced vehicle frames.
Install intersection cameras to deter reckless driving.
3. Head-On Collisions
Head-on collisions occur when the front ends of two vehicles collide, often at high speeds. These accidents are rare but have a high fatality rate due to the combined force of impact. The IIHS reports that head-on crashes made up 10% of fatal accidents in 2022 (IIHS, 2023).
Causes:
Crossing the centerline (e.g., due to distracted or impaired driving)
Overtaking on two-lane roads
Fatigue or falling asleep at the wheel
Road design flaws, such as sharp curves
Prevention:
Use centerline rumble strips to alert drifting drivers.
Avoid driving while fatigued or under the influence.
Adhere to speed limits and road signs.
4. Rollover Accidents
Rollover accidents involve a vehicle tipping over onto its side or roof. These are more common with taller vehicles like SUVs and trucks due to their higher center of gravity. The NHTSA estimates that rollovers accounted for 17% of fatal crashes in 2022, despite being only 2% of total crashes (NHTSA, 2024).
Causes:
Sharp turns at high speeds
Overcorrecting during a skid
Collisions with curbs or other objects
Uneven road surfaces or tire blowouts
Prevention:
Drive at safe speeds, especially on curves.
Ensure proper tire maintenance and vehicle stability control.
Avoid overloading vehicles, which can raise the center of gravity.
5. Sideswipe Collisions
Sideswipe collisions occur when the sides of two parallel vehicles make contact, often during lane changes or merging. While typically less severe, they can cause vehicles to lose control, leading to secondary collisions. The IIHS notes that sideswipe crashes are often underreported but contribute significantly to property damage (IIHS, 2023).
Causes:
Failure to check blind spots
Improper lane changes
Drifting due to distraction or fatigue
Narrow roads or construction zones
Prevention:
Use turn signals consistently.
Install blind-spot monitoring systems.
Check mirrors and surroundings before changing lanes.
6. Single-Vehicle Accidents
Single-vehicle accidents involve only one vehicle, often colliding with fixed objects like trees, poles, or guardrails. These crashes are frequently linked to driver error or environmental factors. According to a 2023 study by the AAA Foundation for Traffic Safety, single-vehicle crashes account for approximately 50% of all accidents (AAA, 2023).
Vehicle accidents result in significant physical, emotional, and financial consequences. Injuries range from minor bruises to severe trauma, such as spinal cord injuries or traumatic brain injuries (TBI). The Centers for Disease Control and Prevention (CDC) estimates that motor vehicle crashes cost the U.S. economy $340 billion annually in medical expenses, lost productivity, and property damage (CDC, 2024). Additionally, survivors may face long-term psychological effects, such as post-traumatic stress disorder (PTSD) (American Psychological Association, 2025).
Strategies for Reducing Vehicle Accidents
Driver Education: Comprehensive driver training programs can teach defensive driving techniques and hazard awareness.
Technology Adoption: Advanced safety features like lane departure warnings, adaptive cruise control, and automatic braking can reduce crash risks.
Infrastructure Improvements: Better road design, improved signage, and traffic calming measures can enhance safety.
Policy Enforcement: Stricter enforcement of traffic laws, such as speed limits and DUI regulations, can deter reckless behavior.
Public Awareness: Campaigns promoting safe driving habits, like avoiding distractions, can foster a culture of responsibility.
Conclusion
Vehicle accidents remain a significant public health and safety concern, with various types posing unique risks and challenges. By understanding the causes and implementing preventive measures, drivers and communities can work together to reduce crashes and their devastating impacts. Staying informed, adopting safety technologies, and advocating for better road policies are crucial steps toward safer roads for everyone.

Optimal joint health is vital to keeping the body moving. They allow us to function throughout the day and perform various tasks. When healthy joints become injured or damaged, the body loses mobility. Joint issues/pain primarily present in the shoulders, wrists, hands, knees, ankles, and spine. Healthy joints are necessary for the full range of motion and comfortable movement. To keep joints healthy and fully functioning, chiropractic treatment is recommended to alleviate joint pain and improve joint health.
Contents
Joint Health
Joints are designed to provide a full range of motion for the body parts they affect.
Joints are made to be able to endure weight and forces applied to them.
Every joint consists of two surfaces that make contact.
The bones that make up the joint allow for movement, but the actual muscles pull the bones that generate movement.
The muscles are attached to bones by tendons.
Tendons are strong enough to facilitate movement and flexible to prevent damage to the muscle tissues.
Ligaments connect the bones and help to prevent uncontrolled movement.
The muscles, tendons, and ligaments are attached around each joint at specific positions and shaped to exact dimensions.
Synovial fluid lines the joints and lubricates the surfaces to reduce friction.
Injury and Conditions
Most injuries to joints occur from added and abnormal stresses placed on a joint.
A joint can become injured from a basic trauma accident. An ankle sprain, for example.
The ankle joint is protected by ligaments on the inside and outside.
When the ankle moves too far inward, the ligaments on the outside can tear.
The ankle swells, leading to pain.
In some instances, small pieces of bone and cartilage can also tear away.
Other injuries
Overuse/Repetitive stress injuries, also known as cumulative trauma disorders, can cause joint pain symptoms.
These injuries happen when stress is repeatedly placed on the joints.
The stress can come from:
Poor posture
Awkward/unusual positioning while working.
Little to no workstation ergonomics.
Arthritis
The most common cause of joint pain is arthritis.
Rheumatoid arthritis causes inflammation of the joints causing swollen and stiff joints, limiting mobility.
Osteoarthritis can also cause joint pain. This is when the joint cartilage breaks down from regular wear and tear.
The aging body becomes stiff, swollen and decreases the range of motion.
Other conditions
Pregnancy can place an incredible amount of pressure on the spine, knees, and hips as the body tries to balance itself with the added weight, causing joint pain.
Obesity can also lead to joint pain from the added weight and pressure.
Health conditions that cause inflammation can lead to joint pain, including Lyme disease and Lupus.
The jawbone is also a joint; Temporomandibular Joint Dysfunction causes jaw pain, difficulty chewing and clicking, or locking.
Chiropractic can restore joint health.
Chiropractic can keep the joints in optimal health and functioning to the fullest. The objective is to activate the body’s natural ability to heal itself by improving the function of the central nervous system. Our team is dedicated to utilizing science-based chiropractic approaches to reduce pain and reverse painful conditions. It is also a natural method for relieving arthritis pain, slowing down the degenerative process, and helping to relubricate the joints.

Mediterranean Diet Can Be a Great Starting Point
There’s no perfect diet. Although human bodies are basically the same, individuals respond differently to certain diets. Diets can only go so far. The individual still has to put in the work of following the diet, exercising, developing new healthy habits, and maintaining them. The Mediterranean diet was reviewed by a panel of nationally recognized experts in:
Nutrition
Food psychology
Diabetes
Heart disease
They reviewed the diet profile to analyze certain categories. They included:
Ease of taking on the diet.
Weight loss effectiveness. This includes short-term and long-term.
The diet’s potential for preventing and managing diabetes.
The diet’s potential for preventing and managing cardiovascular disease.
The findings found the Mediterranean diet to be one of the best because of the many health benefits that come from the dietary changes.

Fibromyalgia is a condition that causes pain throughout the whole body. It causes sleep problems, fatigue, and mental/emotional distress. It affects around four million adults in the United States. Individuals with Fibromyalgia tend to be more sensitive to pain. This is referred to as abnormal/altered pain perception processing. Research currently leans towards a hyperactive nervous system as one of the most plausible causes.
Contents
Symptoms and Related Conditions
Individuals with fibromyalgia/fibromyalgia syndrome/FMS may have:
Fatigue
Sleep issues
Headaches
Concentration, Memory issues, or Fibro Fog
Stiffness
Tender points
Pain
Numbness and tingling in hands, arms, legs, and feet
Central sensitization means that the central nervous system, made up of the brain and spinal cord, processes pain differently and more sensitively. For example, individuals with Fibromyalgia could interpret physiological stimuli, like heat, coldness, pressure, as pain sensations. Mechanisms that cause altered pain processing include:
Pain signal dysfunction
Modified opioid receptors
Substance P increase
Increased activity in the brain where pain signals are interpreted.
Pain Signal Dysfunction
When a painful stimulus is felt, the brain signals the release of endorphins, the body’s natural painkillers that block the transmission of pain signals. Individuals with Fibromyalgia could have a pain-blocking system that is altered and/or not functioning correctly. There is also the inability to block repetitive stimuli. This means that the individual keeps feeling and experiencing the stimuli even as they try to block them out, suggesting a failure in the brain to filter out irrelevant sensory information.
Modified Opioid Receptors
Research has found that individuals with fibromyalgia have a reduced number of opioid receptors in the brain. Opioid receptors are where endorphins bind so the body can use them when necessary. With fewer available receptors, the brain is less sensitive to endorphins, as well as opioid pain medication like:
Hydrocodone
Acetaminophen
Oxycodone
Acetaminophen
Substance P Increase
Individuals with fibromyalgia have been found to have elevated levels of substance P in their cerebrospinal fluid. This chemical is released when a painful stimulus is detected by the nerve cells. Substance P is involved with the body’s pain threshold, or the point when a sensation turns into pain. High levels of substance P could explain why the pain threshold is low in individuals with fibromyalgia.
Increased Activity in the Brain
Brain imaging tests, like magnetic resonance imaging or MRI, have shown that fibromyalgia is associated with greater than regular activity in areas of the brain that interpret pain signals. This can suggest that pain signals are overwhelming those areas or that the pain signals are being processed dysfunctionally.
Triggers
Certain factors can trigger a flare-up. These include:
Diet
Hormones
Physical stress
Too much exercise
Not enough exercise
Psychological stress
Stressful events
Sleep Patterns changed
Treatment changes
Temperature changes
Weather changes
Surgery
Chiropractic
Chiropractic focuses on whole-body wellness. 90% of the central nervous system goes through the spinal cord. A misaligned vertebral bone can create interference and irritation on the nerves. Fibromyalgia is a condition related to the hyperactivity of the nerves; therefore, any vertebral subluxations will complicate and aggravate fibromyalgia symptoms. By realigning the misaligned vertebrae releases the stress off of the spinal cord and spinal nerve root. That is why individuals with fibromyalgia are recommended to add a chiropractor to their healthcare team.

Most individuals don’t think about how they walk or whether they are walking with the correct posture. Knowing how to walk with the proper technique and posture can help:
Ensure the bones and joints maintain proper alignment.
Decrease abnormal wear and tear on the joints, muscles, and ligaments from awkward positions.
Prevent neck, back, hip, and leg pain.
Reduce muscle aches and fatigue.
Reduce injury risk.
Improve balance, stability, and mobility.
Walking with the correct technique and posture is not complicated but requires individuals to stay aware of standing and moving.

Correct Posture
Walking is a physical activity that involves the whole body. It helps to focus on each part of the body to understand how to walk correctly fully.
Head-Up
Focus on standing straight with the chin parallel to the ground and ears aligned above the shoulders.
Imagine the head being pulled gently upwards by an invisible string attached to the sky/ceiling.
This can help prevent dropping the head into the chest while walking.
Maintain eyes forward and gaze.
Focus on an area about 10 to 20 feet ahead when walking.
Straighten and Extend the Spine
Focus on extending the spine while walking.
Avoid slouching, hunching, or leaning forward. This stresses the back muscles.
Relaxed Shoulders Down and Back
The shoulders have a role with posture and technique. Shoulders that are tense or hunched forward can strain the muscles and joints in the shoulders, upper back, and neck. When walking, perform the following:
Raise the shoulders as high as they will go in a shrugging motion, then let them fall and relax.
Shoulder shrugs will help relieve tightness or tension.
This places the shoulders in a natural position that allows for easy arm movement.
Keep the shoulders loose and relaxed.
Shoulder shrugs while walking can help ensure that the shoulders are relaxed and in the correct position.
Swing the Arms
Walking correctly can be helped by gently swinging the arms back and forth at the sides.
Make sure to swing the arms from the shoulders, not from the elbows.
Do not swing the arms across the body.
Do not swing the arms up too high.
Keep them around the midsection, not around the chest.
Engage the Body’s Core
The core muscles have an essential role and help the body move with ease.
To prevent injury or overuse wear and tear on the muscles and joints, it is recommended to avoid the following:
Looking down too frequently
Looking down at the ground or phone too much places unnecessary strain on the neck.
Do not take long strides
The power comes from pushing off of the rear leg.
Overstriding places stress on the lower leg joints.
Rolling or swinging the hips
The hips should stay as level as possible.
Slouching
This will help avoid back and shoulder strain.
Wearing the wrong shoes
Wear the right shoes when walking for more than a few minutes.
Shoes should fit comfortably.
Provide arch and heel support.
Well-cushioned to absorb the shock of the feet hitting the ground.
Benefits of Correct Posture
The physical and mental benefits of proper posture and optimal walking technique include:
Alleviation of muscle and joint pain
Walking properly will avoid placing unnecessary stress and strain on the muscles, ligaments, and joints.
Increased energy
Walking with incorrect/awkward posture can wear out the muscles faster, whereas walking with proper form helps conserve energy.
Improved breathing
Walking with the shoulders back allows the lungs to fill and expand fully. This makes breathing more manageable and efficient.
Improved circulation
When the body is properly aligned and moving correctly, it’s easier for the blood to circulate throughout the body.
Digestion improvement
When the internal organs are not compressed from awkward postures, the body digests food more efficiently and increases blood flow to the digestive tract.
Enhanced core strength
The abdominal muscles gain strength and power from walking correctly.
Reduced headaches
Keeping the head straight, not bending forward, can help reduce neck strain, leading to reduced headaches.
Improved balance
Correct posture improves balance and less prone to falling.
Correct gait and posture are not complicated but do take some practice to develop healthy habits. For any issues with gait or back problems, talk to a doctor, physical therapist, or chiropractor about technique improvement.
Body Composition
Ten-Thousand Steps Speed and Distance
Before deciding to put in the walking distance and time, speed also needs to be considered. Calories burned from walking depend on the intensity, or speed, of the walk. The average walking speed is about 3 miles per hour and the number of calories burned depends on walking speed.
A leisure 30-minute walk at two mph yields a burn of 102 calories
Moderate intensity of 3.5 mph in the same 30-minute walk increases to burn 157 calories.
The faster the pace, the greater the heart rate.
The more calories are burned covering the same distance.
However, reaching 10,000 steps can almost entirely be irrelevant if not careful with a stable caloric intake.

Chocolate is comfort food. When stressed out, frustrated it makes you feel better, and when things are great, it can make them even better. However, there is a difference between the chocolate bar candies on the store shelves and healthy chocolate. Unhealthy chocolate is full of sugar and fat that can cause health problems like acne, obesity, high blood pressure, and diabetes. Healthy dark chocolate can be eaten regularly in moderation to gain a variety of health benefits what to know as far as what type of chocolate should be eaten and how much.
Contents
Healthy Dark Chocolate
All the chocolate snacks, bars, minis, etc., contain added sugar, honey, and butter. These are not healthy for the body. Healthy dark chocolate contains at least 70% cocoa.
Dark Chocolate Nutrition
A 3.5 ounce – 100 grams dark chocolate bar contains:
11 grams of fiber
98% of recommended daily intake of manganese
89% of recommended daily intake of copper
67% of recommended daily intake of iron
58% of recommended daily intake of magnesium
Zinc
Selenium
Potassium
However, one bar contains 600 calories, which is why it needs to be consumed in moderation.
Cardiovascular System Benefits
Studies have shown that dark chocolate can restore elasticity and flexibility to the blood vessels and arteries. It was found to help prevent white blood cells from sticking to the blood vessel walls, a common cause of clogged arteries.
Lowers Cholesterol & Reduces Risk of Heart Disease
Dark chocolate has compounds that prevent the oxidation of LDL or low-density lipoprotein cholesterol. Less cholesterol means a lower risk of heart disease. Researchers found that dark chocolate reduced the risk of heart disease by 50% throughout a 15-year study.
Healthy for Expecting Mothers and Baby
Women that are pregnant and craving sweets can have dark chocolate. Eating dark chocolate can help improve blood flow to the arteries in the uterus. The improved blood flow helps the placenta develop and function normally, leading to a healthy pregnancy and delivery. It is recommended that pregnant women should only consume healthy dark chocolate during the first two trimesters and not in the third trimester. Speak to an obstetrician before making any diet changes.
Can Help Prevent Diabetes
When consumed in moderation, healthy dark chocolate can delay and even prevent the development of diabetes. This is achieved by improving insulin sensitivity. A study found that dark chocolate helped delay diabetes and also helped to lower blood pressure.
Beneficial for the Brain
Dark chocolate has been found to improve blood flow to the brain. This increases overall function. Subjects in a study found that after five days of consuming a small amount of dark chocolate daily, they had significantly increased the amount of blood in the brain. It was also found to help improve cognitive function in elder individuals. Another study found that 90 elderly patients had enhanced verbal skills and improved overall health.
Moderation Health
To be healthy, it needs to be consumed in moderation. This means about 1 ounce a day. A regular-sized healthy chocolate bar contains approximately 3.5 ounces. Therefore the bar should be split into thirds with one piece a day. Read the label carefully and ensure that that dark chocolate has a 70% or higher cocoa content. There can be several types of cocoa are on the label, including:
Cocoa nibs
Cocoa butter
Cocoa powder
All are perfectly healthy additions to a healthy dark chocolate bar.
It is recommended to avoid dark chocolate known as Dutched,or that has been processed with alkali. Treating dark chocolate with alkali reduces the bitter taste but also reduces the healthy antioxidants. Dark chocolate does have some sugar but is far less than the average milk chocolate bar. It is recommended to look for dark chocolate with sugar listed as the last or next to final ingredient on the list. Often the higher the percentage of cocoa, the less sugar.

Overeating
ASAPscience simplified the science of hunger and cravings in the above two-minute video. It explains the body’s hunger-regulation system and the why of second helpings how the appetite works. Appetite is different from hunger. Hunger is the need to eat, while appetite is the desire to snack mindlessly even after a meal. Hunger and appetite are influenced by a network of pathways involving the neuroendocrine system. Appetite regulation, fullness/satisfaction, and energy balance include:
The gut – the largest endocrine organ in the body
Various hormones
The brain
High-calorie foods rich in fat and sugar are highly desirable to the body. This comes from the hunter-gatherer ancestors who sought these foods for survival because they were scarce or difficult to come by. The instinct for fatty and sugary foods is still active even though these foods are available all over. The continual intake of high-calorie fat and sugary foods overrides the body’s natural hunger regulation system, leading to chronic overeating. The more an individual eats foods with high levels of fat and sugar, the more likely the body gets addicted to them.
