Abstract:Objective To analyze the effect of electromyographic biofeedback complicated with resistance training in elderly patients with knee osteoarthritis (KOA). Methods A total of 100 elderly patients with KOA admitted to West China Hospital, Sichuan University from July 2019 to January 2021 were selected as the research subjects. They were divided into observation group and control group by random number table method, with 50 cases in each group. The control group received routine rehabilitation therapy and resistance training, and the observation group received routine rehabilitation therapy and electromyographic biofeedback combined with resistance training. The intervention lasted for 21 days. Visual analog scale (VAS), Western Ontario and McMaster University (WOMAC) osteoarthritis index scale, Lysholm knee score, and isokinetic muscle force parameters (peak moment [PT], total work [TW], work fatigue [WF]) were assessed before and after intervention. The incidence of adverse events in the two groups during intervention was analyzed. Results After intervention, Lysholm knee score in both groups was higher than before intervention, and the observation group was higher than the control group (P < 0.05). After intervention, VAS and WOMAC osteoarthritis index scale scores of the two groups were lower than before intervention, and the observation group was lower than the control group (P < 0.05). After intervention, PT, TW, and WF of knee extension in both groups were higher than before intervention, and the observation group was higher than the control group (P < 0.05). There was no significant difference in the total incidence of adverse events between the two groups (P > 0.05). Conclusion Electromyographic biofeedback combined with resistance training in elderly patients with KOA can effectively reduce pain, enhance anti-fatigue ability, and improve knee function, which is worthy of clinical promotion.
