This study aimed to investigate the effects of a 6-wk proprioceptive neuromuscular facilitation stretching on pain, proprioception, joint range of motion, and joint moments during stair ascending among older adults with knee osteoarthritis.
This study is a randomized, controlled, and assessor-blinded trial. Thirty-six older adults with knee osteoarthritis were randomly assigned to the proprioceptive neuromuscular facilitation and the control groups. They received proprioceptive neuromuscular facilitation stretching and health lecture series, respectively, for 6 wks. Final data analysis included 14 participants of the proprioceptive neuromuscular facilitation group and 13 of the control group. Pain score, joint proprioception, range of motion, and joint moments during stair ascending were measured before and after the stretching. Two-way (group by time) analysis of variance with repeated measures was used to evaluate stretching effects.
Significant interactions were detected in pain score, joint proprioception, external knee adduction moment, and external knee extension moment. Compared with week 0, the pain score, joint proprioception threshold, and external knee adduction moment decreased, whereas the external knee extension moment increased among older adults in the proprioceptive neuromuscular facilitation group at week 7.
Proprioceptive neuromuscular facilitation could be recommended as one of the clinical treatments for knee osteoarthritis to relieve pain, improve proprioception, and balance load distribution between medial and lateral compartments at the knee.
本研究旨在探讨 6 周本体感觉神经肌肉促进拉伸对老年膝骨关节炎患者在上楼梯时疼痛、本体感觉、关节活动度和关节力矩的影响。
这是一项随机、对照、评估者盲法试验。36 名膝骨关节炎老年患者被随机分为本体感觉神经肌肉促进拉伸组和对照组。他们分别接受了 6 周的本体感觉神经肌肉促进拉伸和健康讲座系列。最终数据分析包括本体感觉神经肌肉促进拉伸组的 14 名参与者和对照组的 13 名参与者。在拉伸前后测量疼痛评分、关节本体感觉、关节活动度和上楼梯时的关节力矩。采用双向（组间×时间）重复测量方差分析评估拉伸效果。
疼痛评分、关节本体感觉、膝关节外展力矩和膝关节外伸力矩均检测到显著的交互作用。与第 0 周相比，本体感觉神经肌肉促进拉伸组在第 7 周时疼痛评分、关节本体感觉阈值和膝关节外展力矩降低，而膝关节外伸力矩增加。
本体感觉神经肌肉促进拉伸可作为膝骨关节炎的一种临床治疗方法，以减轻疼痛、改善本体感觉，并平衡膝关节内外侧间的负荷分布。
