Universal goniometer and electro-goniometer intra-examiner reliability in measuring the knee range of motion during active knee extension test in patients with chronic low back pain with short hamstring muscle.


Both universal goniometer and electro-goniometer are used for measuring joint range of motion in physiotherapy. Active knee extension test is a way to assess hamstring shortness in patients with chronic low back pain. The aim of this study was to assess universal goniometer and electro-goniometer reliability in measuring knee angle during active knee extension test.
