腰背肌协调性测试的阻力量选择

Choice of Resistance Amount for Lumbar Muscles' Coordination Test

目的探讨不同的阻力量选择对腰背肌协调性测试结果可信度的影响。方法由1名测试者在1周内分别对30例青年腰痛男子进行2次腰背肌协调性测试。在每次测试中,受试者随机完成5 kg、10 kg和15 kg 3种阻力量的测试,测试内容包括向心运动平均值、向心运动偏移值、离心运动平均值和离心运动偏移值4项。应用组内相关系数(ICC)对3个阻力量组的4项测试结果进行重测信度评价。结果 5 kg阻力量组ICC分别为0.303、0.500、0.358和0.360;10 kg阻力量组ICC分别为0.449、0.382、0.365和0.272;15 kg阻力量组ICC分别为0.453、0.442、0.614和0.411。结论施加15 kg阻力,腰背肌协调性测试具有较好的重测信度。

Objective To explore the effect of different resistance amount on the reliability of the lumbar muscles＇ coordination test.Methods 30 young male adults participated the lumbar muscles＇ coordination test twice within 1 week by the same tester. In each test, the subjects took 5 kg, 10 kg and 15 kg of resistance randomly. The index included mean of concentric motion, deviation of concentric motion,mean of eccentric motion and deviation of eccentric motion. Intra-class correlation coefficient（ICC） for these 4 test results were applied to evaluate the reliability of those tests. Results The ICCs of the 4 test results were 0.303, 0.500, 0.358 and 0.360 respectively in the 5 kg of resistance group, 0.449, 0.382, 0.365 and 0.272 respectively in the 10 kg of resistance group, and 0.453, 0.442, 0.614 and 0.411 respectively in the 15 kg of resistance group. Conclusion The test-retest reliability can be satisfied in the lumbar muscles＇ coordination test with 15 kg of resistance.
