Background: It is important to regain range of motion (ROM) in a joint is one of the first phases of injury rehabilitation in low back pain with limited hip flexion. Through rehabilitation period, it is necessary to measure accurate hip flexion ROM to confirm patient’s progress and condition or therapeutic effectiveness.
Purpose: We investigate the difference between measurement of hip flexion ROM with lumbo-pelvic stabilization (HFwLS) and without lumbo-pelvic stabilization (HFwNLS) and to identify the test-retest reliability of HFwLS.
Study design: Comparative repeated design, Test-retest measures.
Methods: Twenty one students at Yonsei University participated and Forty one legs recruited in this study. Hip flexion ROM was measured using Smart KEMA motion sensor. Data from the motion sensor were recorded at a 25-Hz sampling frequency and transmitted to an Android tablet running Smart KEMA software. During HFwLS, the subject flexes the hip joint of the measurement side in the supine position with maintaining initial pressure of PBU. PBU is placed on the lumbar spine of the subject in supine position, and the initial value is set to 40 mmHg. Paired t-tests were conducted to compare differences between measurement of hip flexion ROM and HFwLS. Intra-class correlation coefficients [ICCs (3,1)] were used to determine the test-retest reliability of HFwLS.
Results: There are significant different between HFwNLS and HFwLS (t=10.04; p<0.01). And the test-retest ICC of the HFwLS was 0.97 (CI range from 0.95?0.99) between first and second measurement.
Conclusions: We suggested that the lumbo-pelvic stabilization could be provided for accurate or reliable measurement of hip flexion ROM measurement without compensatory lumbo-pelvic motion.
