不同目标力矩时距小腿关节肌肉力觉的重测信度（英文）

背景：目前对于距小腿关节矢状面内肌肉力觉的研究较为缺乏,距小腿关节肌肉力觉的测试没有统一的标准。目的：通过分析不同目标力矩时距小腿关节矢状面内运动肌肉力觉的重测信度,探讨距小腿关节肌肉力觉的测量方法。方法：选取跖屈肌群最大等长峰值力矩值的25%,50%和75%作为距小腿关节肌肉力觉的目标力矩值,测试距小腿关节肌肉对这些目标力矩值的复制能力;运用组内相关系数和测量的标准误来判断肌肉力觉的重复测量结果的一致性程度。结果与结论：结果显示用来衡量关节肌肉力觉的可变误差和绝对误差的组内相关系数均大于0.75,而且测量的标准误相对较小;常数误差的组内相关系数均小于0.75,而且测量的标准误相对较大。在目标力矩较小时,用来衡量肌肉力觉的可变误差和绝对误差重测信度较好。

Test-retest reliability of muscle force sense of the ankle joint under different target torque

BACKGROUND：There was no uniform criterion for muscle force sense test of the sagittal plane of the ankle joint.OBJECTIVE：To explore the test-retest reliability of the ankle muscle force sense（MFS） under different target force.METHODS：The target force of the muscle was 25%,50% and 75% maximal voluntary isometric contraction to measure MFS.Consistency degree of the repeated measures was evaluated by intra-class correlation（ICC） and standard error of measurement（SEM）.RESULTS AND CONCLUSION：Interclass correlation coefficients of variable errors and absolute errors in MFS were more than 0.75,and SEM of them were lower.ICCs of constant error of them were less than 0.75,and SEMs of them were greater.The test-retest reliability for variable errors and absolute errors of MFS was better when the target force was smaller.
