Abstract:
Objective To assess the test-retest reliability of pressure biofeedback in measuring intra abdominal pressure in the lumbar region for normal subjects .Methods We choosed 33 subjects (20 to 27 years old) and asked them to do four movements (movement A :prone position ;movement B :supine position with flexion hip and knee joint ;movement C :supine position with single flexion hip and knee joint ;movement D :prone position with flexion shoulder joint ;) by using pressure biofeedback twice totally ,and the last measurement should be done after 24 h .The indicator of test-retest reliability of joint position was intraclass correlation co-efficient (ICC) .Results The test-retest reliability of intra abdominal pressure was modest in the four movements in the lumbar re-gion ,and the values of ICC were from 0 .786 - 0 .848 .The test-retest reliability of intra abdominal pressure was good in Movement A [ICC(95% CI)= 0 .817(0 .630 - 0 .910)] ,Movement B [ICC(95% CI)= 0 .848 (0 .692 - 0 .925)] ,Movement D [ICC(95% CI)= 0 .841(0 .678 - 0 .921)] .And the test-retest reliability of intra abdominal pressure was good in Movement C [ICC (95% CI) =0 .786(0 .566 - 0 .894)] .Conclusion The test-retest reliability of intra abdominal pressure was modest and good in the lumbar re-gion ,and pressure biofeedback could be useful to assess intra abdominal pressure .
