Abstract

|
|
Background: Piriformis syndrome (PS) is described as entrapment of the sciatic nerve at the level of the piriformis muscle. Selecting the most effective conservative treatment for PS continues to be a challenge. The movement-system-impairment (MSI) approach is based on the association of symptoms with incorrect movements of the hip. The purpose of this case report was to describe the MSI-based approach to diagnosis in a patient with PS.
Study design: Case report.
Observations: The patient was a 36-year-old man who presented with sciatic pain in the left lower extremity and anterior hip pain. He began to experience pain approximately 3 months prior to presentation. Prolonged periods spent in a sitting posture aggravated the pain and paresthesia. A clinical examination was performed and the MSI-based diagnosis of hip lateral rotation syndrome was determined. He was instructed to perform specific exercises to address these movement impairments. Exercises were prescribed to address impairments to muscle length, muscle strength, and motor control, all of which are proposed to contribute to the lateral rotation of the hip. The patient reported a reduction in pain and an improvement in his functional activities after 6 weeks of therapy.
Conclusions: The present study suggests that the therapeutic application of the MSI approach is effective in patients with PS.
