BACKGROUND: Piriformis muscle syndrome (PMS) is a condition that can causes local buttock pain and tenderness. The symptoms of PMS are related to the hip joint position and may affect repetitive daily tasks such as walking.
OBJECTIVES: What is the difference between the gait characteristics of patients with PMS and those of matched-healthy controls?
DESIGN: Observational study.
METHODS: Thirty patients with PMS and 30 age-, sex-, and height-matched healthy participants underwent three-dimensional walking analysis.
RESULTS: The results showed no significant differences in the spatiotemporal characteristics of gait between the groups (p > 0.1). The PMS group flexed the hip joint significantly more (-7.2 [-11.9 to -2.2], p = 0.003) and extended the hip joint to a lesser degree (-2.48 [-4.91 to -0.5], p = 0.04) than the control group. Patients with PMS needed a statistically significantly longer time to reach the peak angles of hip internal (1.3 [1 to 1.9], p = 0.003) and external (5.5 [0.9 to 10.1], p = 0.01) rotations during the gait cycle. Further, the results showed that the sagittal range of motion of the knee joint was significantly lesser in patients with PMS than in controls (3.45 [0.4 to 6.4], p = 0.02).
CONCLUSIONS: Patients with PMS seem to have different kinematic changes during level walking. Changing the peak flexion and extension of the hip joint is considered a strategy to enable pain-free gait in patients with PMS. Further, the knee kinematics are modified consequent to the change of hip joint kinematics.
