Chronic Myofascial Pain Syndrome (MPS) is a prevalent condition characterized by persistent pain and muscle tightness, with sensitive knots in the muscles known as trigger points[1]. It affects the musculoskeletal system and is more common among patients with musculoskeletal pain problems[2]. The pain is often localized in areas such as the low backneck, shoulders, and chest[3].

Symptoms and Diagnosis

Patients with MPS experience a wide range of symptoms that can vary in intensity and duration. The most common symptom is persistent or recurring muscle pain, which can be described as a deep, aching, or burning sensation[1]. This pain is often accompanied by tender areas in the muscles, known as trigger points, which can cause both localized and referred pain when pressed[4]. Referred pain is pain that is felt in a different area of the body than where the trigger point is located, and it can be a key indicator of MPS.

In addition to pain, patients with MPS may experience limited range of motion in the affected muscles, as well as muscle stiffness and weakness[1]. These symptoms can lead to difficulty performing daily activities and can significantly impact a person’s quality of life. Fatigue is another common symptom of MPS, as the constant pain and muscle tension can be exhausting both physically and mentally[2].

Other symptoms that may be associated with MPS include headaches, particularly tension headaches, and sleep disturbances[1]. The pain and discomfort caused by MPS can make it difficult to find a comfortable sleeping position, leading to insomnia or poor sleep quality.

Diagnosing MPS can be challenging, as there are no specific tests or imaging studies that can definitively confirm its presence[5]. Instead, healthcare professionals rely on a thorough clinical evaluation, which includes a detailed patient history and physical examination. During the physical exam, the healthcare provider will look for tender areas in the muscles and assess the patient’s range of motion and muscle strength[3].

One of the key diagnostic criteria for MPS is the presence of trigger points, which can be identified through manual palpation[4]. A trigger point is considered active if it causes pain when pressed and reproduces the patient’s symptoms. Latent trigger points may cause discomfort when pressed but do not reproduce the patient’s specific symptoms[1].

Causes and Risk Factors

The exact pathophysiology of MPS is not fully understood, but research suggests that it is a complex disorder involving multiple factors[1]. One of the primary mechanisms thought to contribute to the development of MPS is the formation of trigger points in the muscles. Trigger points are believed to form when muscle fibers become overloaded or injured, leading to the release of inflammatory mediators and the development of a taut band of muscle tissue[2].

Several factors can contribute to the development of trigger points and MPS. Traumatic events, such as car accidents, falls, or sports injuries, can cause direct damage to the muscles and lead to the formation of trigger points[1]. Repetitive strain injuries, often related to occupational or recreational activities, can also contribute to the development of MPS. For example, individuals who perform repetitive motions at work, such as typing or assembly line work, or those who engage in repetitive sports activities, like running or weightlifting, may be at higher risk for developing MPS[2].

Postural imbalances and biomechanical factors can also play a role in the development of MPS[1]. Poor posture, such as slouching or hunching over a desk, can place excessive strain on the muscles of the neck, shoulders, and back, leading to the formation of trigger points. Ergonomic factors, such as improperly adjusted workstations or chairs, can also contribute to postural imbalances and increase the risk of developing MPS[2].

Other risk factors for developing MPS include:

  1. Age: MPS is more common in adults, particularly those over the age of 30[1].
  2. Gender: Women are more likely to develop MPS than men[2].
  3. Sedentary lifestyle: Lack of physical activity can lead to muscle weakness and imbalances, increasing the risk of developing MPS[1].
  4. Poor sleep: Inadequate or poor-quality sleep can exacerbate muscle tension and pain, contributing to the development or worsening of MPS[2].

Treatment Options

Conventional Treatments

The management of MPS typically involves a multidisciplinary approach, combining various treatment modalities to address pain, improve function, and enhance quality of life[1]. Conventional treatments for MPS include:

  1. Physical therapy: Physical therapy is a cornerstone of MPS treatment, focusing on stretching, strengthening, and improving flexibility in the affected muscles[1]. Physical therapists may use techniques such as manual therapy, myofascial release, and trigger point compression to help alleviate pain and improve function[2].
  2. Exercise: Regular exercise is essential for maintaining muscle strength, flexibility, and overall health in patients with MPS[1]. Low-impact aerobic exercises, such as walking, swimming, or cycling, can help improve cardiovascular health and reduce muscle tension.
  3. Pharmacological treatments: Medications can be used to help manage pain and reduce inflammation in patients with MPS[1]. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, can help reduce pain and inflammation in the affected muscles. Muscle relaxants, such as cyclobenzaprine or tizanidine, may be prescribed to help reduce muscle spasms and improve sleep quality[2].
  4. Trigger point injections: Trigger point injections involve the injection of a local anesthetic, saline, or corticosteroid directly into the trigger point to help alleviate pain and reduce muscle tension[4]. These injections can provide rapid relief of symptoms and may be particularly useful for patients with severe or refractory pain[1].

Alternative and Complementary Treatments

In addition to conventional treatments, many patients with MPS may benefit from alternative and complementary therapies[1]. These therapies can be used in conjunction with conventional treatments to help manage symptoms, reduce pain, and improve overall well-being. Some common alternative and complementary treatments for MPS include:

  1. Acupuncture: Acupuncture is a traditional Chinese medicine technique that involves the insertion of thin needles into specific points on the body to help alleviate pain and promote healing[1]. Some studies have suggested that acupuncture may be effective in reducing pain and improving function in patients with MPS[2].
  2. Massage therapy: Massage therapy involves the manipulation of soft tissues, including muscles, tendons, and ligaments, to help reduce pain, improve circulation, and promote relaxation[1]. Various massage techniques, such as Swedish massage, deep tissue massage, and myofascial release, may be used to address specific areas of tension and pain in patients with MPS.
  3. Chiropractic care: Chiropractic care focuses on the diagnosis, treatment, and prevention of neuromuscular disorders, with an emphasis on manual adjustment and manipulation of the spine[1]. Chiropractors may use techniques such as spinal manipulation, mobilization, and soft tissue therapy to help alleviate pain, improve joint function, and promote overall health in patients with MPS.

Lifestyle Changes

In addition to conventional and alternative treatments, lifestyle changes can play a crucial role in managing symptoms and improving overall well-being in patients with MPS[1]. Some key lifestyle changes for managing MPS include:

  1. Regular exercise: Engaging in regular physical activity is essential for maintaining muscle strength, flexibility, and overall health in patients with MPS[1]. Low-impact aerobic exercises, such as walking, swimming, or cycling, can help improve cardiovascular health, reduce muscle tension, and boost mood.
  2. Proper nutrition: Maintaining a balanced, nutrient-rich diet is important for overall health and can help support muscle function and recovery in patients with MPS[1]. Eating a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats can provide the necessary nutrients for muscle health and repair.
  3. Stress management: Stress can contribute to muscle tension and exacerbate symptoms of MPS[1]. Engaging in stress-reducing activities, such as meditation, yoga, or deep breathing exercises, can help promote relaxation and reduce muscle tension.

Prognosis and Management

Chronic MPS has a worse prognosis than its acute counterpart, with symptoms lasting 6 months or longer[1]. While there is no cure for the chronic condition, it is possible to manage it with treatments[2]. The prognosis depends on symptom duration, with acute MPS often resolving spontaneously or after simple treatments, whereas chronic MPS lasts much longer[1].

MPS can co-occur with or mimic other chronic pain conditions, such as:

Differentiating between these conditions and MPS is essential for accurate diagnosis and treatment.
