Clinical TrialInterexaminer reliability of the hip extension test for suspected impaired motor control of the lumbar spine.
The hip extension test may be a clinical sign of impaired motor control in the lumbar spine, which may have a negative impact on spine stability. The purpose of this study is to evaluate the interexaminer reliability of the hip extension test for suspected dynamic instability of the lumbar spine in patients with chronic low back pain. ⋯ The hip extension test appears to have good reliability in detecting deviation of the lumbar spine from the midline. Validity with regard to the test's ability to distinguish patients with chronic low back pain from normal individuals and its relation to lumbar spine stability remains to be determined.
