For individuals dealing with pain, inflammatory conditions, and stress issues, could adding acupuncture to a treatment plan help bring relief and healing?
Acupuncture Treatment
Acupuncture treatment is a traditional Chinese medicine based on circulating the body’s life energy, or qi, with the idea that a blockage or disturbance in the energy flow can cause health issues. Acupuncturists insert thin needles into specific points throughout the body to rebalance the body’s energy, stimulate healing, and promote relaxation. (Johns Hopkins Medicine. 2023) Researchers are not exactly sure how the treatment works; however, theories suggest that it can help release endorphins, as well as influence the autonomic nervous system.
How Does It Work?
Researchers have not been able to understand how acupuncture works fully, but some theories include:
The needles stimulate the release of endorphins – the body’s natural pain-relieving chemicals.
They can influence the autonomic nervous system, and specific needle placement impacts breathing, blood pressure, and heart rate. (Tony Y. Chon, Mark C. Lee. 2013)
The health benefits can vary depending on the individual. It may take several sessions before benefits are noticed. (Tony Y. Chon, Mark C. Lee. 2013) Research is still limited; however, there are some studies that found acupuncture to be helpful for certain conditions.
Low Back Pain
A study on non-pharmacological options for lower back pain showed that acupuncture treatment relieved intense pain and promoted better back functioning.
However, in terms of long-term benefits, it was not clear how helpful the treatment was. (Roger Chou, et al., 2017)
Migraines
Research done over a six-month period showed that:
Acupuncture was able to reduce the frequency of migraine symptoms by half in 41% of individuals compared to those not receiving acupuncture.
Treatment was noted as being helpful as preventative migraine medications. (Klaus Linde, et al., 2016)
Tension Headaches
According to research, having at least six acupuncture sessions may be helpful for individuals with frequent head pain or pressure/tension headaches.
This study also noted that acupuncture, combined with pain medication, significantly reduced headache frequency compared to those only given medication. (Klaus Linde, et al., 2016)
Knee Pain
Multiple studies found that acupuncture treatment may be able to improve knee function short and long-term in individuals who have knee osteoarthritis.
This condition causes the connective tissue in the knee to break down.
The study also found that treatment was able to help with osteoarthritis and decrease knee pain but was only helpful for the short term. (Xianfeng Lin, et al., 2016)
Another review looked at multiple studies that found that treatment delayed and reduced the use of pain medication in individuals who had knee replacement surgery. (Dario Tedesco, et al., 2017)
Facial Elasticity
Cosmetic or facial acupuncture is used to improve the appearance of the skin on the head, face, and neck.
In a study, individuals had five acupuncture sessions in three weeks, and a little over half of the participants showed skin elasticity improvement. (Younghee Yun et al., 2013)
The Process
Before getting acupuncture treatment, the acupuncturist will ask the individual about their medical history and may perform a physical examination.
Thin needles are placed in specific areas to address your concern or condition.
The acupuncturist may gently twist the needles to emphasize stimulation.
The needles are left in for 20 to 30 minutes, with the total session lasting anywhere from 30 minutes to an hour. (Tony Y. Chon, Mark C. Lee. 2013)
This is the burning of dried herbs near the acupuncture needles to warm and stimulate the points and enhance healing.
Electroacupuncture
An electrical device is connected to the needles, providing a gentle electrical current that stimulates the muscles.
Cupping
Glass or silicone cups are placed on the area, creating a vacuum/suction effect, which helps stimulate blood circulation and rebalance the energy. (Johns Hopkins Medicine. 2023)
After the treatment, some individuals may feel relaxed, while others may feel energized.
Is It Painful?
Individuals may feel a slight ache, sting, or pinch as the needle is inserted. Some acupuncturists adjust the needle after it has been inserted, which can cause additional pressure.
Once the needle is properly placed, individuals may feel a tingling or heavy feeling, referred to as de qi. (National Institutes of Health. (N.D.)
Let the acupuncturist know if there is discomfort or increased pain at any point during the session.
In order to reduce the risks, the treatment should always be done by a licensed trained healthcare provider using clean, disposable needles. It is recommended to consult with a primary care physician before getting acupuncture, as the treatment may not be right for individuals with certain health conditions.

For individuals trying to make healthy lifestyle adjustments, can adding protein bars into their diet help achieve health goals?
Protein Bar
Protein bars provide a quick energy boost between meals that can help curb appetite and avoid filling up on high-fat, sodium-packed snacks for individuals trying to lose weight. They can also increase calorie intake for individuals like athletes trying to increase muscle mass. Protein bars can vary in terms of factors like additives, calories, fat, sugars, and other ingredients. Labels need to be read carefully; otherwise, the bar can be more of a candy bar than a healthy, nutritious mini-meal or snack. It’s important to have a sense of how much protein is really needed each day, and the amount varies depending on individual factors.
How Much Protein Is Needed
Protein is vital to many body functions, but the body can’t produce this macronutrient, and it has to come from food. Dietary protein is broken down during digestion, and compounds known as amino acids are formed:
These are the building blocks the body uses to build and maintain muscles and organs.
It is vital to the production of blood, connective tissue, antibodies, enzymes, and hair. (Marta Lonnie, et al., 2018)
As protein is necessary for building muscle, athletes or individuals with physically demanding jobs are recommended to eat more.
The ideal protein intake considers how much is eaten at individual sittings. The average individual is recommended to consume between 25 and 35 grams of protein at every meal. (Emily Arentson-Lantz, et al., 2015)
Sources
The richest sources of dietary protein include:
Meats
Poultry
Fish and shellfish
Eggs
Milk and other dairy products
Plant sources include:
Beans
Legumes
Nuts
Seeds
Whole grains
These are foods that are easy to include in a balanced diet, so eating a variety in ample quantities daily will equal the recommended amount of protein. Recommendations are to stick with those low in saturated fat and processed carbs and rich in nutrients. However, eating too much protein can cause kidney problems. Therefore, individuals who are predisposed to kidney disease are recommended to be careful over-protein intake. (Kamyar Kalantar-Zadeh, Holly M. Kramer, Denis Fouque. 2020)
What To Look For
Incorporating protein bars into a diet, either as a between-meal snack, as a grab-and-go option when there is no time for a full meal, or as a part of a weight-loss or weight-gain strategy, individuals need to read and understand the ingredients on the different types of bars to choosing the healthiest options. Some general guidelines to consider:
Protein Content
For a between-meal or pre-post-workout snack, look for a bar with at least 20 grams of protein.
Meal replacement bars should have at least 30 grams of protein.
A less is more approach to these guidelines is recommended, as the body can digest only between 20 and 40 grams of protein in one sitting. (Brad Jon Schoenfeld, Alan Albert Aragon. 2018)
Protein Type
The protein usually comes from dairy or plant sources.
The most common include eggs, milk, rice, whey, soy, peas, and hemp.
Individuals with allergies or sensitivities need to choose a bar that is comprised of a type of protein that is safe to eat.
Calories
For a bar to eat between meals, recommendations are those with around 220 to 250 calories.
A protein bar that substitutes for a full meal can have 300 to 400 calories.
Fat
Ten to 15 grams of total fat and no more than two grams of saturated fat is ideal.
Steer clear of unhealthy trans fats found in partially hydrogenated oils.
Fiber
Fiber is filling, so the more fiber, the more likely it is to keep hunger satisfied until the next snack or meal.
It is recommended to choose those that contain more than three to five grams of fiber.
Sugar
Some protein bars have just as much sugar content as candy bars.
Some have as much as 30 grams of added sugar.
The ideal amount is around five grams or less.
Artificial sweeteners like erythritol, sorbitol, and maltitol are not better options as they can cause bloating and gas.
It is recommended to work with a nutritionist to figure out the most effective type so that they can be incorporated into an individual’s diet to achieve and maintain health goals.

Individuals who have gone through recent low back surgery, like a lumbar laminectomy and discectomy, could they benefit from physical therapy for full recovery? (Johns Hopkins Medicine. 2008)
Rehabilitation Exercise Program
A lumbar laminectomy and discectomy is a surgical procedure performed by an orthopedic or neurologic surgeon to help decrease pain, relieve associated symptoms and sensations, and improve flexibility and mobility. The procedure involves cutting away disc and bone material that presses against, irritates, and damages the spinal nerves. (Johns Hopkins Medicine. 2023)
Post-Surgery
The therapist will work with the individual to develop a rehabilitation exercise program. The objective of a rehabilitation exercise program is to help the individual:
Relax their muscles to prevent muscle tensing and becoming over-cautious
Regain full range of motion
Strengthen their spine
Prevent injuries
A guide on what to expect in physical therapy.
Postural Retraining
After back surgery, individuals have to work to maintain proper posture when sitting and standing. (Johns Hopkins Medicine. 2008)
Postural control is important to learn as it maintains the lower back in the optimal position to protect and expedite the healing of lumbar discs and muscles.
A physical therapist will teach the individual how to sit with proper posture and use lumbar support.
Attaining and maintaining proper posture is one of the most important things to help protect the back and prevent future back problems.
Walking helps to improve cardiovascular health and blood circulation throughout the body.
This helps to provide added oxygen and nutrients to the spinal muscles and tissues as they heal.
It is an upright exercise that puts the spine in a natural position, which helps to protect the discs.
The therapist will help set up a program tailored to the individual’s condition.
Prone Press Up
One of the exercises to protect the back and lumbar discs is prone press-ups. (Johns Hopkins Medicine. 2008) This exercise helps keep the spinal discs situated in the proper position. It also helps to improve the ability to bend back into lumbar extension.
To perform the exercise:
Lie facing down on a yoga/exercise mat and place both hands flat on the floor under the shoulders.
Keep the back and hips relaxed.
Use the arms to press the upper part of the body up while allowing the lower back to remain against the floor.
There should be a slight pressure in the lower back while pressing up.
Hold the press-up position for 2 seconds.
Slowly lower back down to the starting position.
Repeat for 10 to 15 repetitions.
Sciatic Nerve Gliding
Individuals who had leg pain coming from the back prior to surgery may have been diagnosed with sciatica or an irritation of the sciatic nerve. Post-surgery, individuals may notice their leg feels tight whenever straightening it out all the way. This could be a sign of an adhered/trapped sciatic nerve root, a common problem with sciatica.
After lumbar laminectomy and discectomy surgery, a physical therapist will prescribe targeted exercises called sciatic nerve glides to stretch and improve how the nerve moves. (Richard F. Ellis, Wayne A. Hing, Peter J. McNair. 2012)
Nerve glides can help free the stuck nerve root and allow for normal motion.
To perform the exercise:
Lie on the back and bend one knee up.
Grab underneath the knee with the hands.
Straighten the knee while supporting it with the hands.
Once the knee is fully straightened, flex and extend the ankle about 5 times.
Return to the starting position.
Repeat the sciatic nerve glide 10 times.
The exercise can be performed several times to help improve how the nerve moves and glides in the lower back and leg.
Supine Lumbar Flexion
After surgery, gentle back flexion exercises can help safely stretch the low-back muscles and gently stretch the scar tissue from the surgical incision. Supine lumbar flexion is one of the simplest exercises to improve lumbar flexion range of motion.
To perform the exercise:
Lie on the back with the knees bent.
Slowly lift the bent knees towards the chest and grasp the knees with both hands.
Gently pull the knees toward the chest.
Hold the position for 1 or 2 seconds.
Slowly lower the knees back to the starting position.
Perform for 10 repetitions.
Stop the exercise if experiencing an increase in pain in the lower back, buttocks, or legs.
Hip and Core Strengthening
Once cleared, individuals can progress to an abdominal and core strengthening program. This involves performing specific motions for the hips and legs while maintaining a pelvic neutral position. Advanced hip strengthening exercises help generate strength and stability in the muscles that surround the pelvic area and lower back. A physical therapist can help decide which exercises are recommended for the specific condition.
Return-to-Work and Physical Activities
Once individuals have gained an improved lumbar range of motion, hip, and core strength, their doctor and therapist may recommend working on specific activities to help them return to their previous level of work and recreation. Depending on job occupation, individuals may need to:
Work on proper lifting techniques.
Require an ergonomic evaluation if they spend time sitting at a desk or workstation.
Some surgeons may have restrictions on how much an individual can bend, lift, and twist from two to six weeks after surgery.
Low-back surgery can be difficult to rehab properly. Working with a healthcare provider and physical therapist, individuals can be sure to improve their range of motion, strength, and functional mobility to return to their previous level of function quickly and safely.

Individuals experiencing headaches on top of the head could be caused by different factors. Can recognizing what triggers pain or pressure help prevent this type of headache, and healthcare providers develop effective treatment plans?
Headache On Top of The Head
Various factors could cause a headache on top of the head; common causes include:
Stress
Sleep problems
Eye strain
Caffeine withdrawal
Dental problems
Hormonal changes
Alcohol consumption
Causes
Many causes have to do with underlying issues happening in other parts of the body.
Stress
Stress is a common cause of headaches, including one on top of the head.
Researchers don’t know exactly how stress causes headaches, but they think it causes tightening of the muscles in the back of the head or neck, which
pulls the tissues down, resulting in pain or pressure in the scalp and/or forehead area.
These are also called tension headaches.
Headaches caused by stress generally feel like dull pressure rather than throbbing pain.
Sleep Problems
Not getting enough sleep can induce a headache on top of the head.
When the mind and body do not get proper sleep, it can interfere with body functions like temperature, hunger, and sleep-wake cycles, which can lead to headaches.
It is common to feel more stressed when sleep-deprived, which can cause or compound a headache and other symptoms.
Eye Strain
You may develop a headache on the top of your head after you’ve been reading, watching, or otherwise focusing on something for a while.
Over time, your eye muscles tire and have to work harder, causing them to contract.
These spasms can lead to headaches. Squinting can make the muscle contractions even worse.
Caffeine Withdrawl
Individuals may feel pain on the top of their heads if they skip their regular coffee.
Regular caffeine consumption can lead to dependency and withdrawal symptoms, which include headaches when intake is reduced or stopped.
This type of headache can be moderate to severe and can feel worse with activity.
Teeth issues like cracks, cavities, or impaction can irritate the trigeminal nerve, setting off head pain.
Teeth grinding can also lead to headaches.
Hormonal Changes
Individuals who have a low level of thyroid hormone may experience headaches.
This could be from having too little thyroid or a symptom of the condition.
Like stress-induced headaches, this type is generally dull and not throbbing.
Some women may feel pain on the top of their heads before menstruation triggered by estrogen levels dropping.
Alcohol
Some individuals develop a headache on the top of their head or elsewhere within a few hours after drinking alcohol.
This is known as a cocktail headache.
Alcohol-induced headaches usually resolve within 72 hours.
The mechanism behind this headache is not fully researched, but it’s been thought that the widening of blood vessels in the brain/vasodilation when consuming alcohol may trigger head pain.
This type of headache is different than a hangover headache that comes from overconsumption and is based on dehydration and the toxic effects of alcohol. (J G Wiese, M. G. Shlipak, W. S. Browner. 2000)
Rare Causes
Top-of-the-head pain can also result from more serious and rare causes:
Brain Tumor
Headaches are one of the most common symptoms of brain tumors.
A headache on the top of the head depends on the location and size of the tumor. (MedlinePlus. 2021)
Brain Aneurysm
This is a weak or thin area in a brain artery that bulges and fills with blood, which can cause a life-threatening rupture.
A medical professional will be able to help identify the type of headache being experienced, offer treatment options, and advise on how to manage triggers.
For individuals looking to increase their antioxidant, fiber, and vitamin intake, can adding pomegranates to their diet help?
Pomegranates
Pomegranates can amplify various dishes, from breakfasts to sides to dinners, with their balanced blend of mild sweetness, tartness, and crunch from their seeds.
Health Benefits
The fruit has been found to be a healthy source of vitamins, fiber, and antioxidants. A medium-sized fruit contains:

Individuals dealing with chronic knee discomfort, hip tightness, and lower back pain could be experiencing dormant gluteal-butt syndrome. Can recognizing the symptoms and signs and incorporating lower body and core fitness help prevent and treat the condition?
Dormant Gluteal Butt Syndrome
Knee, hip, and lower back problems could be traced back to weakened buttocks. Some scientists call the condition “dormant butt syndrome” (Ohio State University, .2023). However, researchers are learning about the important role the gluteal muscles provide in maintaining the lower body strong and healthy. (Hal David Martin, Manoj Reddy, Juan Gómez-Hoyos. 2015)
What Is It?
The syndrome is defined as weak buttock muscles and tight hip flexors. Experts from the Ohio State Wexner Medical Center have worked with individuals dealing with knee, hip, or back injuries and believe many of these issues are linked to weakened gluteal muscles. (Ohio State University.2023) The glutes are the muscles of the hips and buttocks. Weakened muscles fail to absorb the shock they’re supposed to during activities, which results in overloading the surrounding muscles and joints and increases the risk of injury. (Ohio State University, .2023)
Dormant gluteal-butt syndrome can result from a sedentary lifestyle and prolonged inactivity, like sitting for long periods.
The condition also occurs in runners and other physically active individuals who forget about these muscles with targeted exercises.
Exercises
Exercises to target the gluteals and prevent dormant gluteal-butt syndrome include activities/exercises that work the hips and core.
When walking properly, the gluteals should execute hip extension naturally.
Unhealthy postures, excessive sitting, and continued dysfunctional biomechanics mean walking without achieving optimal hip extension. (Hadi Daneshmandi. 2017)
When this happens, the gluteal muscles never get to fully function work, ending up with a series of aches and pains.
Pilates exercises can be adjusted to address order, repetition, and variation to strengthen the gluteals. (Laís Campos de Oliveira, 2015)
Hamstring Curls
Lie face down on an exercise mat.
Use your hands to create a cushion for the forehead.
Bend both knees so the feet point up towards the ceiling.
Let the knees be slightly apart, but keep the heels together.
Squeeze the heels together and tighten the gluteal muscles.
Hold for 3 seconds, then release the buttocks.
Repeat 10 times and then rest.
Hamstring curls can also be done using a weight machine.
Place the hands just behind the backside with the fingers pointing forward if possible.
Raise the body up.
Keep your head up and look straight ahead.
Raise one leg as high as possible.
Hold for as long as possible.
Lower and raise the other leg.
Repeat for a total of 3 reps.
Lining Up With A Wall Posture Helper
Standing posture is important to proper buttock function. Lining the body up with a wall can help train the body to maintain proper posture.
Find a wall and stand against it from the heels to the back of the head.
Work the backs of the legs and spine as firmly as possible into the wall.
Work to get the back of the skull into the wall as well.
Add some abdominal work by working the waistline inward and upward.
Hold for up to one minute.
The alignment is how you want to hold your body.
As you move off the wall, learn to maintain that posture throughout the day and night.
Repeat the wall exercise several times for reinforcement.
If aching of the hip, back, or knee is part of daily struggles, working out the gluteal muscles may be the solution. Contact the Injury Medical Chiropractic and Functional Medicine Clinic for a full consultation.

“Various problems with the sacrum make up or contribute to a significant portion of lower back problems. Can understanding the anatomy and function help prevent and treat back injuries?”
The Sacrum
The sacrum is a bone shaped like an upside-down triangle located at the base of the spine that helps support the upper body when sitting or standing and provides pelvic girdle flexibility during childbirth. It comprises five vertebrae that fuse during adulthood and connect to the pelvis. This bone takes and endures all of the body’s pressure and stress from everyday activities and movements.
Formation
Humans are born with four to six sacral vertebrae. However, fusion does not take place in all sacral vertebrae simultaneously:
Fusion starts with the S1 and S2.
As the individual gets older, the overall shape of the sacrum begins to solidify, and the vertebrae fuse into a single structure.
The process usually starts in the mid-teens and finishes in the early to mid-twenties.
It is believed to start earlier in females than males.
The sacrum in a female is wider and shorter and has a more curved top or the pelvic inlet.
The male sacrum is longer, narrower, and flatter.
Structure
The sacrum is an irregular bone that makes up the back/posterior third of the pelvic girdle. There is a ridge across the front/anterior portion of the S1 vertebra known as the sacral promontory. Small holes/foramen on both sides of the sacrum are left over after the vertebrae fuse together. Depending on the number of vertebrae, there can be three to five foramen on each side, though there are usually four. (E. Nastoulis, et al., 2019)
Each anterior foramen is typically wider than the posterior or dorsal/backside foramen.
Each sacral foramina/plural of foramen provides a channel for the sacral nerves and blood vessels.
Small ridges develop between each of the fused vertebrae, known as transverse ridges or lines.
The top of the sacrum is called the base and is connected to the largest and lowest of the lumbar vertebrae – L5.
The bottom is connected to the tailbone/coccyx, known as the apex.
The sacral canal is hollow, runs from the base to the apex, and serves as a channel at the end of the spinal cord.
The sides of the sacrum connect to the right and left hip/iliac bones. The attachment point is the auricular surface.
Right behind the auricular surface is the sacral tuberosity, which serves as an attachment area for the ligaments that hold the pelvic girdle together.
Location
The sacrum is at the level of the lower back, just above the intergluteal cleft or where the buttocks split. The cleft starts at around the level of the tailbone or coccyx. The sacrum is curved forward and ends at the coccyx, with the curvature being more pronounced in females than males. It connects to the L5 lumbar vertebra by way of the lumbosacral joint. The disc between these two vertebrae is a common source of low back pain.
On either side of the lumbosacral joint are wing-like structures known as the sacral ala, which connect to the iliac bones and form the top of the sacroiliac joint.
These wings provide stability and strength for walking and standing.
Anatomical Variations
The most common anatomical variation applies to the number of vertebrae. The most common is five, but anomalies have been documented, including individuals with four or six sacral vertebrae. (E. Nastoulis, et al., 2019)
Other variations involve the sacrum’s surface and curvature, where the curvature differs widely between individuals.
In some cases, the first and second vertebrae do not fuse and remain separately articulated.
Failure of the canal to completely close during formation is a condition known as spina bifida.
Function
Studies on the sacrum are ongoing, but some proven functions include:
It serves as an anchor point for the spinal column to attach to the pelvis.
It provides stability for the body’s core.
It acts as a platform for the spinal column to rest on when sitting.
It facilitates childbirth, providing pelvic girdle flexibility.
It supports upper body weight when sitting or standing.
It provides extra stability for walking, balance, and mobility.
Conditions
The sacrum can be a main source or focal point for lower back pain. It is estimated that 28% of men and 31.6% of women aged 18 years or older have experienced low back pain in the past three months. (Centers for Disease Control and Prevention. 2020) Conditions that can cause sacrum pain symptoms include.
Sacroiliitis
This is a common condition of sacroiliac/SI joint inflammation.
A doctor only makes the diagnosis when all other possible causes of pain have been ruled out, known as a diagnosis of exclusion.
About half of all chordomas form in the sacrum, but the tumors can also develop elsewhere in the vertebral column or at the base of the skull. (National Library of Medicine. 2015)
Spina Bifida
Individuals can be born with conditions that affect the sacrum.
Spina bifida is a congenital condition that can arise from the malformation of the sacral canal.
