阶段性抗阻训练联合运动表象训练在膝关节置换术后护理中的应用

Abstract: Objective To explore the effect of using staged resistance training and motor imagery training (MIT) nursing in patients after knee replacement surgery. Methods A total of 98 patients who underwent knee replacement surgery and were admitted to our hospital from July 2022 to October 2024 were selected. They were randomly divided into the intervention group (n=49) and the control group (n=49). Both groups received routine rehabilitation training, the control group was additionally given MIT, while the intervention group received staged resistance training combined with MIT. knee function gait stability and balance, and knee range of motion were compared between the two groups. Results After intervention, the Hospital for Special Surgery (HSS) scores in both groups were increased (P＜0.05), while the HSS scores in the intervention group were significantly higher than those in the control group (P＜0.05). After intervention, the step frequency and berg balance scale (BBS) scores in both groups were increased (P＜0.05), and the step length was prolonged (P＜0.05), compared to the control group, the intervention group had higher step frequency and BBS scores (P＜0.05), and longer step length (P＜0.05). After intervention, the extension angle of the knee joints in both groups was decreased (P＜0.05), and the flexion angle was increased (P＜0.05), compared to the control group, the extension angle of the knee joints in the intervention group was smaller (P＜0.05), and the flexion angle was larger (P＜0.05). Conclusion The application of staged resistance training combined with MIT nursing in patients after knee replacement surgery can improve knee joint function, promote improvement in knee joint range of motion, and enhance gait balance and stability.
