全身振动训练结合常规康复训练对膝前痛的疗效研究OA

Objective To examine the efficacy of whole-body vibration training combined with conventional rehabilitation train-ing on knee joints in individuals with anterior knee pain,and to provide a safe and efficient rehabilitation program for the treatment of anterior knee pain.Methods A total of 40 patients with anterior knee pain were randomly divided into two groups:a control group receiving conventional rehabilitation training(n=20),and an experimental group receiving whole-body vibration training combined with conventional rehabilitation training(n=20).Each training session lasted 50 minutes,conducted 3 times per week(with at least one rest day between sessions),for a total duration of 8 weeks.Before and after the intervention,outcomes including pain intensity,knee function(Anterior Knee Pain Scale,AKPS),quality of life(SF-36 scale),knee joint peak torque at 60°/s and 180°/s,and knee proprioception were assessed.Results Compared with pre-intervention,the experimental group showed significant differences in VAS scores(P＜0.01),AKPS scores(P＜0.01),scores in the physical functioning,role-physical,bodily pain,and vitality do-mains of the SF-36(P＜0.01),knee flexor and extensor peak torque(P＜0.01),and knee proprioception(P＜0.01).The control group also showed significant improvements in the above indicators(P＜0.01),except for proprioception,which did not change sig-nificantly(P＞0.05).Between-group comparisons revealed that only knee joint proprioceptive angle difference improved more signif-icantly in the experimental group than in the control group(P＜0.01).Conclusion Both whole-body vibration training combined with conventional rehabilitation training and conventional rehabilitation training alone can significantly improve knee pain,knee func-tion,quality of life,and knee flexor and extensor muscle strength in individuals with anterior knee pain.However,there was no signifi-cant difference between the two intervention regimens in most outcome measures except for proprioception.
