Can various therapeutic options provide relief for individuals with upper crossed syndrome to restore muscle strength?
Introduction
Many individuals often suffer neck and shoulder pain from poor posture, improper heavy lifting, musculoskeletal conditions, auto accidents, whiplash, etc. The surrounding muscles that connect the neck and shoulders help protect the cervical and thoracic region of the spine and can succumb to injuries that can cause pain-like symptoms causing discomfort to the individual. Neck, shoulder, and back pain are the three most common issues many individuals have experienced. These musculoskeletal disorders can also correlate with pre-existing conditions; many people will feel pain and discomfort while trying to find the relief they seek. One of the most common issues people often experience is upper crossed syndrome, which can be associated with neck and shoulder pain. Today’s article explains what upper cross syndrome is and how it affects the neck and shoulders while also diving into how different therapeutic options like spinal decompression and chiropractic care can reduce the effects of upper cross syndrome. We speak with certified medical providers who incorporate our patients’ information to provide numerous treatment plans to mitigate upper-crossed syndrome in the neck and shoulders. We also inform our patients that there are many therapeutic options, like chiropractic care and spinal decompression, to minimize muscle pain in the neck and shoulders. We encourage our patients to ask intricated and educational questions to our associated medical providers about the pain-like symptoms they are experiencing correlating with upper-crossed syndrome. Dr. Alex Jimenez, D.C., utilizes this information as an academic service. Disclaimer
What Is Upper Crossed Syndrome?
Have you been dealing with muscle pain in your shoulders or neck after being on the computer for a while? Do you feel stiffness in your shoulders that rotating them causes temporary relief? Or does it hurt when you turn your head from side to side? Many of these pain-like scenarios are often associated with upper-cross syndrome. Many people don’t often realize that upper crossed syndrome is a musculoskeletal condition that affects the neck, shoulder, and chest muscles and causes them to be weak and tight due to poor posture. The upper crossed syndrome can cause referred pain to the upper extremities, leading to cervicogenic headaches, limited range of motion, trigger points in the muscles, and muscle imbalance. (Moore, 2004) When many people are dealing with upper crossed syndrome due to poor posture, it can lead to many issues in the neck and shoulders.
How Does It Affect The Neck & Shoulders?
Now, why does upper crossed syndrome affect the neck and shoulders? Many people unintentionally hunched over when looking at their phones, being on the computer, or relaxing at home. This causes specific muscles in the neck and shoulder region, like the serratus and lower trapezius muscles, to become weak while the pectoral and neck muscles are tight. (Chu & Butler, 2021) This, in turn, causes the shoulders to be more rounded and hunched, causing the neck and head to crane forward. When people are dealing with upper crossed syndrome, many would often complain about pain-like symptoms like:
Headaches
Neck Strain
Muscle tightness
Upper back pain
Restricted range of motion
Numbness/Tingling sensations in the arms
The upper crossed syndrome can also occur gradually over time and cause nerve compression to the upper extremities. When the upper neck and shoulder muscles start to affect the surrounding nerve roots, which then leads to nerve dysfunction in the sensory and motor skills when a person picks up an object. (Lee & Lim, 2019) However, many individuals dealing with upper-crossed syndrome can seek treatment to relieve muscle pain in their neck and shoulders.
An Overview Of Upper Crossed Syndrome- Video
Since upper cross syndrome is a musculoskeletal condition that affects the neck and shoulders, it can result in muscle imbalance and pain in the individual. Many people, especially in the working field, develop this syndrome by being hunched over for an extended period. (Mujawar & Sagar, 2019) This causes the head to be more forward, the neck posture to be curved and hunched, and the shoulders to be rounded. The video above explains upper-crossing syndrome, its causes, and how it is treated.
Numerous treatments can help restore muscle strength and reduce muscle pain in the neck and shoulders. Treatments like spinal decompression can help reduce upper crossed syndrome by slowly using gentle traction to the cervical spine region and gently stretching the neck muscles to provide relief. Spinal decompression is one of the non-surgical treatments that many individuals with headaches associated with upper crossed syndrome can find the comfort they seek through pain reduction and improve their quality of life. (Eskilsson et al., 2021) At the same time, spinal decompression can be part of a personalized treatment plan that many individuals can add to their daily routine to prevent the pain from returning. (Saunders, 1983)
Chiropractic Care Restoring Muscle Strength
Just like spinal decompression, chiropractic care is a non-surgical treatment that can be combined with various stretching techniques to restore the neck’s range of motion and reduce pain associated with upper-crossed syndrome. (Mahmood et al., 2021) Chiropractic care incorporates manual and mechanical techniques like MET (muscle energy techniques) and spinal manipulation to realign the spine out of subluxation. When chiropractors integrate MET to manage upper crossed syndrome, many individuals find that their pain has decreased, their cervical range of motion is improved, and their neck disability is reduced. (Gillani et al., 2020) When many individuals start thinking about their health and wellness, they can make small changes to improve their posture and be more mindful of their bodies to reduce the chances of upper-cross syndrome returning.

Individuals that sit at a desk/workstation for hours for work or school, or drive for a living, could be fostering a long-term condition known as forward head posture. Can understanding the signs and symptoms help to prevent the condition?
Forward Head Posture
Neck pain often causes or is caused by misalignment in the area between the shoulders and head. Forward head posture is a common problem that can strain the neck muscles, leading to pain and worsening neck, shoulder, and back posture. (Jung-Ho Kang, et al., 2012) For individuals who are at risk of developing or are already showing signs/symptoms, it’s important to get medical attention to prevent complications, such as chronic neck pain or compressing a nerve. Individuals can continue to do the work that they need to do but may need some postural adjustments and re-training so as not to continue straining the neck while working.
Postural Deviation
The head is in a healthy alignment with the neck when the ears line up with the gravity line.
The gravity line is an imaginary straight line that represents gravity’s downward pull.
It is used in posture assessments as a reference for noting the positions of the body and determining the presence of any postural misalignment or deviation.
A forward head posture occurs when the head begins to position forward of the gravity line when looking at the body from the side.
Forward head posture is a postural deviation because the head varies from the reference line. (Jung-Ho Kang, et al., 2012)
Muscle Imbalances
Forward head posture often results in a strength imbalance between muscles that support and move your neck, shoulders, and head. (Dae-Hyun Kim, et al., 2018)
The muscles in the back of the neck become shortened and overactive as they flex forward, while the muscles in the front become lengthened, weaker, and strained when they relax.
Kyphosis
Kyphosis also known as hunchback is when the shoulders round forward, and the head is also brought forward. (Jung-Ho Kang, et al., 2012) After many hours sitting at a desk, computer, or driving, kyphosis can also cause and/or worsen forward head posture.
This occurs because the upper back area supports the neck and head.
When the upper back moves or changes position, the head and neck follow.
The majority of the head’s weight is in the front, and this contributes to the forward movement.
An individual with kyphosis has to lift their head to see.
Treatment
A chiropractic injury specialist team can develop a personalized treatment plan to relieve pain symptoms, provide postural retraining, realign the spine, and restore mobility and function.
Standing and sitting using a healthy posture, along with exercises to strengthen the neck muscles, can help get the spine in alignment. (Elżbieta Szczygieł, et al., 2019)
Targeted stretching can help if the neck muscles are tight.
At-home stretches may also relieve pain
Risk Factors
Pretty much everyone is at risk of developing a forward head posture. Common risk factors include:
Constantly looking down at a phone and staying in this position for a long time aka text neck.
Desk jobs and computer use can significantly round the shoulders and upper back, leading to a forward head posture. (Jung-Ho Kang, et al., 2012)
Driving for a living causes prolonged back, neck, and shoulder positioning.
Sleeping or reading with a large pillow under the head can contribute to forward head posture.
Doing work that requires dexterity and close-up positions, like a seamstress or technician can cause over-positioning of the neck.
Individuals who regularly carry a significant amount of weight in front of their body may begin to develop kyphosis.
An example is carrying a child or another load in front of the body.
Large breasts can also increase the risk of kyphosis and forward head posture.

Individuals feeling tingling or pins and needles sensations that overtake the arms or legs could be experiencing paresthesia, which occurs when a nerve has been compressed or damaged. Can knowing the symptoms and causes help in diagnosis and treatment?
Paresthesia Body Sensations
The numbness or tingling feeling when an arm, leg, or foot has fallen asleep is not so much about blood circulation but nerve function.
Paresthesia is an abnormal sensation felt in the body due to the compression or irritation of nerves.
It can be a mechanical cause like a compressed/pinched nerve.
Or it may be due to a medical condition, injury, or illness.
The symptoms typically last for 30 minutes or less.
Shaking the affected limb often relieves the sensations.
Paresthesia usually affects only one arm or leg at a time.
However, both arms and legs can be affected, depending on the cause.
Consult a healthcare provider if the symptoms last for more than 30 minutes. Treatment may be required if paresthesia body sensations are brought on by a serious underlying cause.
Causes
Sitting with incorrect and unhealthy postures can compress a nerve and generate symptoms. However, some causes are more concerning and can include:
If the symptoms don’t go away after 30 minutes or keep returning for unknown reasons, call a healthcare provider to find out what is causing the abnormal sensations. A worsening case should be monitored by a healthcare provider.
Peripheral neuropathy caused by diabetes usually begins with a feeling of paresthesia in the foot/feet and can worsen and lead to other complications.
A healthcare provider will work with the individual to understand the symptoms and perform the appropriate diagnostic tests to determine the cause. A healthcare provider will choose the tests based on a physical examination. Common diagnostic procedures include: (Merck Manual Professional Version. 2022)
Magnetic resonance imaging – MRI of the spine, brain, or extremities.
X-ray to rule out bone abnormalities, like a fracture.
Blood tests.
Electromyography – EMG studies.
Nerve conduction velocity – NCV test.
If paresthesia is accompanied by back or neck pain, a healthcare provider may suspect a compressed/pinched spinal nerve.
If the individual has a history of diabetes that is poorly controlled, they may suspect peripheral neuropathy.
Treatment
Treatment for paresthesia depends on the diagnosis. A healthcare provider can help determine the best course of action for the specific condition.
Nervous System
If symptoms are triggered by a central nervous condition like MS, individuals will work closely with their healthcare provider to get the appropriate treatment.
If paresthesia is caused by compression of a spinal nerve, like sciatica, individuals may be referred to a chiropractor and physical therapy team to release the nerve and pressure. (Julie M. Fritz, et al., 2021)
A physical therapist may prescribe spinal exercises to relieve compression of the nerve and restore normal sensations and motion.
Strengthening exercises to restore flexibility and mobility may be prescribed if weakness presents along with paresthesia body sensations.
Herniated Disc
If a herniated disc is causing the abnormal sensations, and there has been no improvement with conservative measures, a healthcare provider may suggest surgery to relieve pressure on the nerve/s. (American Association of Neurological Surgeons. 2023)
In surgical procedures like a laminectomy or discectomy, the objective is to restore nerve function.
Post-surgery, individuals may be recommended to a physical therapist to help regain mobility.

Individuals dealing with back pain problems could be suffering from a bulging disc. Could knowing the difference between slipped and herniated disc symptoms help with treatments and finding relief?
Bulging Disc Pain
Back pain can become debilitating if not treated properly. A bulging disc is a common cause of cervical, thoracic, and lower back pain symptoms. It happens when one of the fluid-filled cushions between the vertebrae begins to shift out of place. Instead of being aligned with the edges, the disc bulges over. This begins to generate pressure on the nerves causing pain and inflammation.
Bulging discs are often caused by age, but repetitive movements and/or lifting heavy objects can contribute to the condition.
Symptoms can resolve on their own, but individuals are recommended to consult with a physical therapist and/or chiropractor to make sure the disc healed properly, otherwise, it can lead to worsening and/or further injuries.
Bulging Disc vs. Herniated Disc
Bulging and herniated discs cause pain symptoms.
They both can be linked to injuries and degenerative disc disease but are not the same condition. (Penn Medicine. 2018)
This is because the lower back is subject to all kinds of pressure and movement with daily activities, increasing the chances of pain and injuries.
The next most common place is the neck/cervical spine where there are constant movements making it prone to injury and pain symptoms.
Causes
Bulging discs are most often caused by body aging and normal wear and tear. As time goes on the intervertebral discs naturally degenerate, known as degenerative disc disease. This can cause the discs to pull downward, causing them to bulge from their placement. (Penn Medicine. 2018) Factors that can cause or worsen the condition include:
Practicing unhealthy postures.
Repetitive motions.
Lifting heavy objects
Spinal injuries.
Medical history of spinal or disc disease in the family.
Individuals with back pain that interferes with daily functions or has lasted longer than six weeks, should see a healthcare provider for a diagnosis. They will order a magnetic resonance imaging scan/MRI, which can show where a disc is protruding. (American Academy of Neurological Surgeons. 2023)
Rest
For bulging disc pain, resting the back is necessary. However,
For individuals looking to maintain wellness or begin their wellness journey like increasing antioxidants, protection against cancer, immune system support and other health benefits, can adding onions be a nutritious way to improve overall health?
Onions
Onions are nutritious vegetables like garlic, chives, leeks, and shallots. The most common types are red, white, yellow, and Spanish onions. They have antifungal, antibacterial, anti-inflammatory, and other healthful properties.
Whichever way they are prepared they do lose some of their nutritional value when cooked.
They contain flavonoids, glutathione, selenium compounds, vitamin E, and vitamin C.
When selecting onions, look for those without blemishes or discoloration, that are firm, and have dry, papery skins.
Benefits
They contain phytochemicals – compounds plants produce to fight off harmful bacteria, viruses, and fungi. These phytochemicals provide health benefits when consumed and provide the following properties: (Xin-Xin Zhao, et al., 2021)
Protect the cardiovascular, digestive, respiratory, reproductive, and neurological systems.
Protect against liver disease.
Support a healthy immune system.
Types and Varieties
They belong to the Allium plant genus which includes plants like garlic, leeks, and chives. (Oregon State University. 2022)
They vary in flavor and can be sweet, tangy, and sour.
Different varieties combined with farming practices contribute to the flavor profile of onions.
There are many varieties of onions.
The most common and widely available are red, white, yellow, and Spanish.
Other types include cipollini, pearl, and Vidalia.
Raw or Cooked
They are beneficial whether eaten raw or cooked, cooking them reduces the number of thiosulfinates – compounds that provide antimicrobial, antifungal, and antibiotic properties.
Boiling and frying onions has been shown to cause the most significant loss in nutritious value.
Other preparation methods that decrease health benefits include sautéing, steaming, and microwaving.
Baking onions is shown to increase flavonoid levels.
Consuming dried, powdered onions can also provide nutritious value to foods, especially if the powder is freeze-dried. (Damini Kothari, et al., 2020)
Nutrition Facts
Onions can contribute to a healthy diet. The flavonoids, glutathione, selenium compounds, vitamin E, and vitamin C, contribute to the antioxidant properties of the vegetable. (Holly L. Nicastro, et al., 2015) The nutrition information for one medium onion: (U.S. Department of Agriculture. N.D.)
Total calories: 44
Total fat: 0 grams
Cholesterol: 0 milligrams
Carbohydrates: 10 grams
Dietary fiber: 2 grams
Total sugars: 5 grams
Protein: 1 grams
Calcium: 2 milligrams
Sodium: 4 milligrams
Iron: 1 milligrams
Vitamin D: 0 micrograms
When Selecting
Onions can contain pesticide residue, heavy metals, microbial contamination, and nitrate accumulation. Knowing where the onions come from can help ensure there was no incorrect use of pesticides or that the soil they were grown in was not enriched with heavy metals. When possible, purchase from reputable sources with transparent farming practices, like the farmers markets. (Xin-Xin Zhao, et al., 2021)
Onions found in environments that have not been effectively sterilized have an increased risk of growing harmful bacteria.
To avoid contamination of Escherichia. coli or E. coli, salmonella, and mold, it’s safest to purchase whole onions and cut them at home rather than purchasing pre-chopped onions. (Xin-Xin Zhao, et al., 2021)
Select those that feel firm, have little to no bruises or discolored spots, and have dry papery skin.
Avoid those that show evidence of mold, like white or black spots on the surface or inside the layers, and those with green shoots, which means the onion is still edible but won’t last that long.

Individuals who engage in a regular fitness regimen can begin to lose interest and motivation. Can knowing the signs of exercise burnout help individuals rediscover their motivation?
Exercise Burnout
When maintaining fitness and health becomes a chore and doing anything else is better than working out, individuals could be experiencing exercise burnout. Here are a few signs an individual is getting burned out.
Procrastination
One sign is constantly putting things off.
An individual may put on workout clothes, set up the equipment, etc.
However, the workout never happens as the individual continues to find other things to do.
At some point, they decide it’s too late and they’ll work out tomorrow.
Solution
Simplify the workout. Make some small goals or adjustments and keep the workout light. (Nemanja Lakicevic, et al., 2020) An example could be:
Focus only on stretching.
Take a walk around the block.
Go up and down some stairs equivalent to a few laps.
Do 10 pushups, 10 squats, and 10 lunges, or other exercises and that’s it.
No Longer Interesting
When burned out, exercise is not interesting and disenchanting. (Franklin Velasco, Rafael Jorda. 2020) Trainers will suggest finding something positive about the workouts.
When the interest and passion are nowhere to be found don’t engage in the usual workouts, as this can further decrease motivation.
This is the time to change up the routine and go for a leisurely bicycle or rollerblade, skateboard, etc., session.
Go to a park, just walk around, and forget about exercise just taking in everything.
Play a game with a friend or toss a ball around.
Exhaustion
Not just physical, but mental fatigue could be a sign of exercise burnout.
Solution
Rest.
Individuals may think they have to work out every day and stick to the regimen or else they’ve failed.
This type of mindset can lead to burnout and added stress.
The body and mind require adequate recovery time.
Forget about structured exercise for a day, and see how the mind and body feel the next day.
Two or three days off in a row can make a significant difference in motivation and offer a new perspective on the workout routine.
Low Energy Levels After Exercise
Workouts, although tiring in a good way, should energize the individual. Most workouts should leave the body feeling better than before. When the body feels worse or energy levels are low, this could be a sign of overtraining that could lead to exercise burnout.
Solution
This could be the time to ease off of the fitness regimen.
This is a form of active recovery, allowing the mind and body to rest from the overwork.
Mood Changes and/or Irritability
When the mind and body are overworked and over-trained, it can cause moodiness, irritability, and frustration that leads to burnout.
Solution
Do something that feels good. This could include:
A therapeutic massage.
A spa session.
Taking a long nap.
Soaking the feet.
Taking a therapeutic bath.
Meditation
Burnout can happen, the objective is to keep the solutions simple like taking a few days off or trying something new to come back feeling refreshed and energized.

Individuals diagnosed with peripheral neuropathy, or with small fiber neuropathy, can understanding symptoms and causes help with potential treatments?
Small Fiber Neuropathy
Small fiber neuropathy is a specific classification of neuropathy, as there are different types, which are nerve injury, damage, disease, and/or dysfunction. Symptoms can result in pain, loss of sensation, and digestive and urinary symptoms. Most cases of neuropathy like peripheral neuropathy involve small and large fibers. Common causes include long-term diabetes, nutritional deficiencies, alcohol consumption, and chemotherapy.
Small fiber neuropathy is diagnosed after diagnostic testing showing it is clear that the small nerve fibers are involved.
The small nerve fibers detect sensation, temperature, and pain and help regulate involuntary functions.
Isolated small-fiber neuropathy is rare, but research is ongoing on the type of nerve damage and potential treatments. (Stephen A. Johnson, et al., 2021)
Small fiber neuropathy is not specifically dangerous but is a sign/symptom of an underlying cause/condition that is damaging the body’s nerves.
Pain – symptoms can range from mild or moderate discomfort to severe distress and can happen at any time.
Loss of sensation.
Because the small nerve fibers help with digestion, blood pressure, and bladder control – symptoms of autonomic dysfunction can vary and can include:
Constipation, diarrhea, incontinence, urinary retention – the inability to completely drain the bladder.
If there is progressing nerve damage, the intensity of the pain can decrease, but the loss of normal sensation and autonomic symptoms can worsen. (Josef Finsterer, Fulvio A. Scorza. 2022)
Hypersensitivity to touch and pain sensations can cause pain without a trigger.
The loss of sensation can make individuals unable to accurately detect sensations of touch, temperature, and pain in affected areas, which can lead to various types of injuries.
Although more research is needed, certain disorders that were not considered neuropathies may have small fiber neuropathy components involved.
A study suggested that neurogenic rosacea, a skin condition, could have some elements of small fiber neuropathy. (Min Li, et al., 2023)
These small nerve fibers are distributed throughout the body including the tops of the fingers and toes, trunk, and internal organs.
These fibers are usually located in the superficial areas of the body, such as close to the skin’s surface. (Mohammad A. Khoshnoodi, et al., 2016)
The small nerve fibers that get damaged are involved in transmitting pain and temperature sensations.
Most nerves have a special type of insulation called myelin that protects them and increases the speed of nerve impulses.
Small nerve fibers may have a thin sheath, making them more susceptible to injury and damage at earlier stages of conditions and diseases. (Heidrun H. Krämer, et al., 2023)
Individuals At Risk
Most types of peripheral neuropathy cause damage to the small and large peripheral nerve fibers. Because of this, most neuropathies are a mix of small-fiber and large-fiber neuropathy. Common risk factors for mixed fiber neuropathy include: (Stephen A. Johnson, et al., 2021)
Diabetes
Nutritional deficiencies
Overconsumption of alcohol
Autoimmune disorders
Medication toxicity
Isolated small-fiber neuropathy is rare, but there are conditions that are known to contribute to the cause and include: (Stephen A. Johnson, et al., 2021)
Sjogren Syndrome
This autoimmune disorder causes dry eyes and mouth, dental problems, and joint pain.
It can also cause nerve damage throughout the body.
Fabry Disease
This condition causes a buildup of certain fats/lipids in the body that can lead to neurological effects.
Amyloidosis
This is a rare disorder that causes a buildup of proteins in the body.
The proteins can damage tissues like the heart or nerves.
Lewy Body Disease
This is a neurological disorder that causes dementia and impaired movement and can lead to nerve damage.
Lupus
This is an autoimmune disease that affects joints, skin, and sometimes nerve tissue.
Viral Infection
These infections typically cause a cold or gastrointestinal/GI upsetness.
Less often they can cause other effects like small fiber neuropathy.
These conditions have been seen to cause isolated small-fiber neuropathy or begin as small-fiber neuropathy before progressing to the large nerve fibers. They can also begin as a mixed neuropathy, with small and large fibers.
Progression
Often the damage progresses at a relatively moderate rate, leading to added symptoms within months or years. The fiber nerves that are affected by the underlying condition usually progressively deteriorate, regardless of where they are located. (Mohammad A. Khoshnoodi, et al., 2016) Medications can help alleviate damage to the peripheral nerves. For individuals that are diagnosed in the early stage, it is possible to stop the progression, and potentially prevent involvement of the large fibers.
Treatments
Treatment toward preventing the progression requires controlling the underlying medical condition with treatment options depending on the cause. Treatments that can help prevent the progression include:
Blood sugar control for individuals with diabetes.
Immune suppression for control of autoimmune diseases.
Plasmapheresis – blood is taken and the plasma is treated and returned or exchanged for the treatment of autoimmune diseases.
Symptom Treatment
Individuals can get treatment for the symptoms that will not reverse or cure the condition but can help with temporary relief. Symptomatic treatment can include: (Josef Finsterer, Fulvio A. Scorza. 2022)
Pain management can include medications and/or topical analgesics.
Physical therapy – stretching, massage, decompression, and adjustments to keep the body relaxed and flexible.
Rehabilitation to help improve coordination, which can be impaired by loss of sensation.
Medications to relieve GI symptoms.
Wearing specialized clothes such as neuropathy socks to help with foot pain symptoms.
Treatment and medical management of neuropathies usually involve a neurologist. A neurologist may prescribe medication to help alleviate pain symptoms and provide medical interventions like immunotherapy if there is concern that an autoimmune process could be the cause. Additionally, treatment could include the care of a physical medicine and rehabilitation physician or a physical therapy team to provide stretches and exercises to help strengthen the body and maintain mobility and flexibility.
