摘要:
目的 探究本体感觉神经肌肉促进技术(PNF)对膝内侧间室骨关节炎老年患者步行时膝外展力矩和股内侧肌-内侧腓肠肌(VM-MG)共激活指数的影响。
方法 2022年3月至5月,在济南社区招募膝骨关节炎老年患者32例,随机分为对照组(n = 16)和训练组(n = 16)。训练组接受PNF治疗,对照组自行居家运动,共6周。治疗前后采用红外运动捕捉系统同步三维测力台和肌电图系统测量患者平地步行时的膝外展力矩和肌肉共激活指数。
结果 对照组3例脱落,训练组2例脱落。治疗后,训练组膝外展力矩第一峰值、第二峰值和VM-MG共激活指数均较治疗前改善(|t| > 2.460, P < 0.05),且训练组膝外展力矩第一峰值、第二峰值均较对照组改善(|t| > 2.454, P < 0.05)。
结论 PNF有助于促进膝骨关节炎患者膝关节内外间室负荷的均匀分布。
