A Movement-System-Impairment Approach to the Evaluation and Treatment of a Patient with Femoral Anterior Glide Syndrome: A Case Report

Abstract

Background Femoral anterior glide syndrome (FAGS) occurs because of inadequate posterior glide of the femoral head during hip flexion. FAGS can occur with and without medial rotation. The most common form of FAGS occurs with hip medial rotation. 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 for the diagnosis of FAGS in a single patient. Study design Case report. Observations A 31-year-old female patient had severe pain in the right hip and knee. Four months previously, she complained of pain while walking, which she developed after exercising on the floor for a long time. A clinical test based on the MSI approach led to the diagnosis of FAGS. The patient was instructed to perform an MSI-based special exercise program. Through 5 weeks of the MSI exercise program, changes in muscle length, muscle strength, and movement control of the hip were observed, resulting in reduced pain and improved functional movement. Conclusions The present study suggests that the therapeutic application of the MSI approach is effective in patients with FAGS.
