There are indications that segmental stabilising exercises (SSEs) are effective in the treatment of low back pain. The evaluation of successful training in SSE performance in patients requires a reliable outcome measure. The PRONE test gives an indication of the activity of the transversus abdominis muscle. Performed in prone lying using a pressure biofeedback unit, it has been used as an aid to training and to assess the subject's ability to perform SSEs correctly.
To evaluate inter-observer and test-retest reliability of the PRONE test.
Repeated measures by three observers on 2 days.
Department of Physical Medicine and Rehabilitation, Ludwig-Maximilian University, Munich, Germany.
Forty nurses (39 females and one male), aged between 24 and 62 years, with at least one episode of low back pain.
During the test, movement of the abdominal wall was monitored by measuring a change in pressure during muscle contraction termed 'abdominal hollowing'. Defined observation and palpation criteria were verified by the observers to ensure correct execution of the test.
Participants were tested on two separate days. On the first day, Observer A performed two similar test sets, each with four exercises. On the second test day, Observers B and C conducted one test set each.
This study found an intra-class correlation coefficient (ICC) of 0.47 [95% confidence interval (CI) 0.20 to 0.67] for inter-observer reliability, and an ICC of 0.81 (95% CI 0.67 to 0.90) for test-retest reliability. Kappa values and the limits of agreement were also calculated with similar results.
For this subject group, the PRONE test had relatively low inter-observer reliability but, as may be expected, higher test-retest reliability. It is suggested that by providing visual feedback, the PRONE test may enhance patients' insight into their deep abdominal muscle recruitment and thereby increase their motivation to exercise.
有迹象表明，节段性稳定练习（SSEs）在治疗腰痛方面有效。评估患者SSEs训练的成功与否需要可靠的结果指标。俯卧测试可显示腹横肌的活动情况。该测试在俯卧位使用压力生物反馈装置进行，已被用于辅助训练并评估受试者正确进行SSEs的能力。
评估俯卧测试的观察者间信度和重测信度。
由三名观察者在两天内进行重复测量。
德国慕尼黑路德维希 - 马克西米利安大学物理医学与康复系。
40名护士（39名女性和1名男性），年龄在24至62岁之间，至少有过一次腰痛发作。
在测试过程中，通过测量肌肉收缩时压力的变化（称为“腹部凹陷”）来监测腹壁的运动。观察者需验证既定的观察和触诊标准，以确保测试的正确执行。
参与者在两个不同的日子接受测试。第一天，观察者A进行两组相似的测试，每组包含四项练习。在第二天的测试中，观察者B和C各进行一组测试。
本研究发现观察者间信度的组内相关系数（ICC）为0.47 [95%置信区间（CI）0.20至0.67]，重测信度的ICC为0.81（95% CI 0.67至0.90）。还计算了kappa值和一致性界限，结果相似。
对于该受试者群体，俯卧测试的观察者间信度相对较低，但正如预期的那样，重测信度较高。建议通过提供视觉反馈，俯卧测试可能会增强患者对其深部腹肌募集的认识，从而提高他们的锻炼积极性。
