Effect of Active Stretching and Instrument-Assisted Soft Tissue Mobilization on the Hip Joint Range of Motion and Stiffness of the Tensor Fascia Lata in Subjects with Shortened Tensor Fascia Lata

Abstract

Background Various therapeutic methods have been suggested to increase the flexibility of shortened muscles in patients with knee pain. However, no previous study has directly compared the hip joint range of motion (ROM) and muscle stiffness as a mechanical property following the active stretching (AS) and instrument-assisted soft tissue mobilization (IASTM) for shortened tensor fascia lata (TFL).
