This study compared isokinetic and non-dynamometric tests for their correlation with subjective low back pain symptoms.
A total of 185 patients with chronic low back pain were examined.
The repetitive arch-up and sit-up tests correlated significantly with pain and disability (Million index) both in men and women (r ranged from -0.39 to -0.46; P < 0.001). In women, the isokinetic trunk flexion and extension tests and the non-dynamometric tests correlated equally well with the Million index. In men, the isokinetic flexion and extension tests had weaker correlations. Overall, the isokinetic lifting tests showed lower correlations than did the isokinetic trunk extension tests. In the isokinetic flexion and extension tests, fast testing speeds (120 degrees/sec and 150 degrees/sec) correlated somewhat better with the subjective symptoms than did the lowest speed (30 degrees/sec).
The non-dynamometric tests are still useful in clinical practice in spite of the development of more accurate muscle strength evaluation methods.
本研究比较了等速测试和非测力测试与主观下背痛症状的相关性。
共检查了185例慢性下背痛患者。
反复弓背和仰卧起坐测试与男性和女性的疼痛及功能障碍（Million指数）均显著相关（r值范围为-0.39至-0.46；P<0.001）。在女性中，等速躯干屈伸测试和非测力测试与Million指数的相关性同样良好。在男性中，等速屈伸测试的相关性较弱。总体而言，等速举重测试的相关性低于等速躯干伸展测试。在等速屈伸测试中，快速测试速度（120度/秒和150度/秒）与主观症状的相关性略优于最低速度（30度/秒）。
尽管有了更精确的肌肉力量评估方法，但非测力测试在临床实践中仍然有用。
