IFS1 and QFS1 are supine and adductive, IFS2 and QFS2 are adductive and externally pronated at 30°, IFS3 and QFS3 are internally pronated at 30°, IFS4 and QFS4 are hip flexion at 30°, IFS5 and QFS5 are prone and posterior extension at 30°. IFS, ischiofemoral space; QFS, quadratus femoris space; ICC, intraclass correlation coefficient.
