INTRODUCTION
This study aimed to determine the intra- and inter-session reliability of neuromuscular assessment of plantar flexor (PF) muscles at three knee angles.
METHODS
Twelve young adults were tested for three knee angles (90°, 30° and 0°) and at three time points separated by 1 hour (intra-session) and 7 days (inter-session). Electrical (H reflex, M wave) and mechanical (evoked and maximal voluntary torque, activation level) parameters were measured on the PF muscles. Intraclass correlation coefficients (ICC) and coefficients of variation were calculated to determine intra- and inter-session reliability.
RESULTS
The mechanical measurements presented excellent (ICC>0.75) intra- and inter-session reliabilities regardless of the knee angle considered. The reliability of electrical measurements was better for the 90° knee angle compared to the 0° and 30° angles.
CONCLUSIONS
Changes in the knee angle may influence the reliability of neuromuscular assessments, which indicates the importance of considering the knee angle to collect consistent outcomes on the PF muscles.
简介
本研究旨在确定在三种膝关节角度下对足底屈肌（PF）肌肉进行神经肌肉评估的内-间测试可靠性。
方法
12 名年轻成年人在三种膝关节角度（90°、30°和 0°）下进行测试，并在 1 小时（内间测试）和 7 天（间间测试）的三个时间点进行测试。对 PF 肌肉进行电（H 反射、M 波）和机械（诱发和最大自主扭矩、激活水平）参数测量。计算组内相关系数（ICC）和变异系数以确定内-间测试可靠性。
结果
无论考虑的膝关节角度如何，机械测量均表现出极好的内-间测试可靠性（ICC>0.75）。与 0°和 30°角度相比，90°膝关节角度的电测量可靠性更好。
结论
膝关节角度的变化可能会影响神经肌肉评估的可靠性，这表明在 PF 肌肉上收集一致结果时考虑膝关节角度的重要性。
