Fibromyalgia is a chronic disorder characterized by persistent and widespread musculoskeletal pain, tenderness, fatigue, sleep disturbances, and other symptoms. While fibromyalgia can cause muscle weakness, it is distinct from muscle atrophy or nerve impairment. Studies have shown that fibromyalgia patients experience a significant reduction in muscle function and strength without a decrease in muscle mass, a condition known as dynapenia. However, there is ongoing research into the potential link between fibromyalgia and sarcopenia, which is the atrophy of muscular fibers associated with a reduction in their number.

Fibromyalgia is characterised by chronic widespread pain and fatigue
Fibromyalgia is a chronic pain disorder characterised by widespread pain and fatigue. It is a long-term condition that affects the way the brain and spinal cord process painful and non-painful signals, increasing overall sensitivity to pain. This improper signal processing often results in ongoing muscle discomfort and fatigue.
The pain associated with fibromyalgia is often described as a constant dull ache lasting at least three months. It is considered widespread if it occurs on both sides of the body, above and below the waist. The slightest touch can cause pain, and it tends to linger for longer than usual. This chronic pain is regarded as the core characteristic of fibromyalgia.
The fatigue experienced by people with fibromyalgia is often accompanied by sleep disturbances, with many patients reporting unrefreshed sleep. They may wake up feeling tired, even after sleeping for long hours. This disrupted sleep can further exacerbate chronic pain and ongoing tiredness, creating a cycle that worsens the muscle weakness associated with the condition.
Fibromyalgia can significantly impact balance and gait, affecting mobility and daily activities. However, it typically does not lead to total immobility, and it is possible to improve muscle strength and walking ability through targeted interventions. These interventions may include physical therapy, lifestyle adjustments, and the incorporation of medications and supplements to relieve pain and improve quality of life.

Patients experience reduced physical activity and increased sedentary behaviour
Fibromyalgia is a chronic disorder characterised by persistent and widespread musculoskeletal pain, tenderness, fatigue, sleep disturbances, and other somatic symptoms. The condition is known to cause muscle weakness and discomfort, which can affect patients' daily activities and reduce their physical capacity and quality of life.
Patients with fibromyalgia experience reduced physical activity and increased sedentary behaviour. Studies have shown that fibromyalgia can significantly impact patients' balance and gait, or their walking style. However, these changes in mobility typically do not progress to the point of total immobility, where patients lose all ability to walk.
The muscle weakness experienced by patients with fibromyalgia is distinct from general fatigue or chronic fatigue syndrome. While physical muscle deterioration or nerve impairment is usually not the cause of muscle weakness in fibromyalgia, patients can lose muscle strength and tone if they are moving less, a condition known as deconditioning.
Fibromyalgia is associated with altered skeletal muscle characteristics, including peripheral mechanisms such as altered muscle fibre size distribution and decreased capillary density. These alterations may contribute to post-exertional fatigue in patients with fibromyalgia, particularly in post-menopausal women. Studies have found that self-reported fatigue and pain were correlated with a prolonged loss of strength following recovery from fatiguing exercise in subjects with fibromyalgia.
In addition to the musculoskeletal pain and functional changes observed in fibromyalgia, there is also evidence of a loss of muscle mass, or atrophy, in patients with the condition. This loss of muscle mass has been observed in rodent models of fibromyalgia, with reduced sympathetic nervous system (SNS) activity implicated in the development of muscle atrophy. However, studies in humans have shown that fibromyalgia patients can experience a significant reduction in muscle function without any loss of muscle mass, a condition known as dynapenia.

Fibromyalgia can impact balance and gait, but not to the point of total immobility
Fibromyalgia is a chronic disorder characterised by persistent and widespread musculoskeletal pain, tenderness, fatigue, unrefreshing sleep, and other symptoms. It can cause muscle weakness and affect daily activities. However, it is important to distinguish between muscle weakness caused by fibromyalgia and that caused by other conditions, such as multiple sclerosis or rheumatoid arthritis.
While fibromyalgia can impact balance and gait, studies have shown that it typically does not lead to total immobility. The changes in walking and balance are due to the pain, stiffness, and other symptoms associated with fibromyalgia. However, it is essential to note that physical muscle deterioration or nerve impairment is usually not the cause of muscle weakness in fibromyalgia. Instead, it is often a result of reduced physical activity and increased sedentary behaviour.
Research has indicated that fibromyalgia is associated with altered skeletal muscle characteristics, which may contribute to post-exertional fatigue, particularly in post-menopausal women. This fatigue can be influenced by peripheral mechanisms such as altered muscle fibre size distribution and decreased capillary density. Additionally, hormonal fluctuations during menstrual cycles, pregnancy, and menopause can intensify fibromyalgia symptoms and worsen muscle weakness.
To manage muscle weakness and improve muscle strength in individuals with fibromyalgia, a multidisciplinary approach is often recommended. This may include physical therapy, lifestyle adjustments, and the incorporation of certain medications and supplements. By addressing the broader aspects of the condition, individuals can aim to relieve pain and improve their overall quality of life.
While fibromyalgia can impact balance and gait, causing changes in walking style and the ability to maintain balance, it does not render individuals completely immobile. With proper management and treatment, individuals with fibromyalgia can improve their muscle strength and ability to walk. Understanding the underlying causes of muscle weakness in fibromyalgia is crucial for developing effective treatment strategies.

Studies show a significant reduction in muscle function without loss of muscle mass
Fibromyalgia is a chronic disorder characterized by persistent and widespread musculoskeletal pain, tenderness, fatigue, unrefreshing sleep, and other symptoms. It affects around 2-5% of the US population, with women having prevalence rates nine times higher than men.
While fibromyalgia can cause muscle weakness, this is distinct from general fatigue or chronic fatigue syndrome. Physical muscle deterioration or nerve impairment is typically not the cause of muscle weakness in fibromyalgia. However, studies have shown that fibromyalgia can significantly impact balance and gait, or walking style.
Despite the muscle weakness associated with fibromyalgia, studies have found no evidence of muscle atrophy or loss of muscle mass in patients with the condition. Instead, the loss of muscle function without a decrease in muscle mass is called dynapenia. This is distinct from sarcopenia, which is the atrophy of muscle fibers associated with a reduction in the number of fibers.
One study assessed sarcopenia in patients with fibromyalgia using bioimpedance analysis to evaluate muscle mass, a handgrip strength test to evaluate muscle strength, and the Short Physical Performance Battery to evaluate physical performance. The study found that muscle strength and physical performance were significantly lower in the fibromyalgia group than in the control group. However, there was no statistical difference between the two groups in terms of skeletal muscle mass.
Another study evaluated muscle biopsies from postmenopausal women with and without fibromyalgia to assess between-group differences in baseline muscle properties. While there was no significant difference in muscle fatigue in response to exercise between the two groups, self-reported fatigue and pain were correlated with a prolonged loss of strength following 12 minutes of recovery in subjects with fibromyalgia.
In summary, while fibromyalgia is associated with muscle weakness and reduced physical capacity, studies suggest that this is due to dynapenia rather than sarcopenia, as there is no evidence of muscle atrophy or loss of muscle mass in patients with the condition.

Treatments include physical therapy, lifestyle changes, medication and supplements
Fibromyalgia is a complex, chronic pain condition that affects up to 10 million people in the United States, with 75% of diagnosed adults being women. While there is currently no cure, there are several treatments that can help manage the symptoms of fibromyalgia, including physical therapy, lifestyle changes, medication, and supplements.
Physical Therapy
Physical therapy can help patients understand and manage their pain, reduce fatigue, and improve their overall function and quality of life. A physical therapist will personalize a treatment plan that may include manual therapy, electrical stimulation, meditation, cognitive behavioral therapy, and biofeedback.
Lifestyle Changes
Lifestyle changes can include adjusting your environment to make yourself more comfortable, getting a good night's sleep, and finding a bedtime ritual that works for you, such as taking a warm bath, reading a book, or listening to music. Massage therapy and acupuncture have also been shown to help with pain management and improving sleep.
Medication
Three medications are approved by the FDA for treating fibromyalgia: duloxetine, milnacipran, and pregabalin. Other drugs, like muscle relaxants, anti-seizure medicines, and anti-depressants, are also used to help treat this condition.
Supplements
Some supplements that may help relieve fibromyalgia symptoms include magnesium, melatonin, St. John's wort, and red ginseng. However, it is important to note that there is limited long-term research on the safety and effectiveness of supplements, and it is always best to consult with a healthcare professional before starting any new supplement regimen.
