Effects of MET and MFR on Piriformis Syndrome

The Effect of Muscle Energy Technique and Myofascial Release Technique on Pain Threshold, Muscle Activation Pattern, and Muscle Strength in Piriformis Syndrome

The aim of this study is to comparatively evaluate the effects of two different manual therapy approaches, Muscle Energy Technique (MET) and Myofascial Release Technique (MFR), on pain threshold, muscle activation patterns, and muscle strength in individuals diagnosed with piriformis syndrome.

In this study, the physiological effects of both interventions on the musculoskeletal system will be assessed using objective measurement tools such as an algometer, digital dynamometer, and electromyography (EMG). The study aims to provide evidence-based data regarding the most effective and preferable manual therapy approach in the conservative treatment of piriformis syndrome.

Inclusion Criteria:

• Individuals diagnosed with piriformis syndrome
• Presence of piriformis tenderness and sciatic symptoms
• Aged between 18 and 65 years
• Voluntary agreement to participate in the study
• No history of lumbar, hip, knee, or ankle surgery within the last year
• Ability to cooperate with the assessment and treatment procedures

Exclusion Criteria:

• Individuals younger than 18 years or older than 65 years
• Presence of any musculoskeletal disorder affecting the lower extremity
• Presence of neurological, cardiac, pulmonary, or orthopedic disorders preventing participation in exercise
• Presence of neurological deficits (muscle strength loss)
• History of radiotherapy to the lumbar or hip region
• Absence from more than 20% of treatment sessions
• Inability to comply with the study procedures (e.g., cognitive impairment, communication problems, severe psychiatric disorders)
• Corticosteroid or PRP injection within the last 3 months
• Participation in another physical therapy program within the last 3 months
• Use of analgesic, anti-inflammatory, or muscle relaxant medications within the last 48-72 hours
• Use of psychotropic medications that may affect muscle activation or nervous system responses (e.g., antidepressants, antipsychotics, sedatives)
