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。
Objective To explore the effect of proprioceptive neuromuscular facilitation(PNF)on the knee abduction torque and vastus medialis-medial gastrocnemius(VM-MG)co-contraction index during walking among the old patients with medial compartment knee osteoarthritis.Methods From March to May,2022,32 old patients with medial compartment knee osteoarthritis in communities in Ji'nan were enrolled and randomly allocated to control group(n=16)and training group(n=16).The training group received PNF and the control group received home-based exercise,for six weeks.The knee abduction torque and VM-MG co-contraction index were measured using an infrared motion capture system synchronized with 3D force plate and electromyography system before and after treatment.Results Three cases in the control group and two cases in the training group dropped off.The first and the second peaks of knee abduction torque,and the VM-MG co-contraction index improved in the training group after treatment(|t|>2.460,P<0.05),and the first and the second peaks of knee abduction torque were better in the training group than in the control group(|t|>2.454,P<0.05).Conclusion PNF may optimize the load distribution between the medial and lateral compartments of the knee in patients with knee osteoarthritis.
