The Effect of Pro-kin Balance System Combined with Blood Flow Restriction Training on Knee Prop-rioception,Knee Joint Function,and Motor Coordination in Patients after Anterior Cruciate Liga-ment Reconstruction Surgery
[Objective]To explore the effects of Pro-kin balance system combined with blood flow restriction(BFR)training on knee proprioception,knee joint function,and motor coordination in patients undergoing anterior cruciate liga-ment reconstruction surgery.[Methods]A total of 82 patients who underwent anterior cruciate ligament reconstruction sur-gery in our hospital from January 2020 to January 2023 were selected and randomly divided into an observation group and a control group using a random number table method,with 41 patients in each group.The control group received postopera-tive BFR training,while the observation group received postoperative Pro-kin balance system training in addition to the con-trol group.After 3 months of treatment,two groups were compared in terms of quadriceps cross-sectional area,flexor ex-tensor ratio(H/Q),relative peak torque(PT/BW),knee proprioceptive index,knee joint function score,and motor coordi-nation.[Result s]The difference in cross-sectional area of the quadriceps femoris muscle on the affected side between 7 days and 3 months after surgery in the observation group was smaller than that in the control group(P＜0.05);The difference in H/Q,PT/BW,30° position deviation,60° position deviation,collaborative contraction rate,and average energy fre-quency between the observation group at 7 days and 3 months after surgery was greater than that of the control group(P＜0.05).The difference in knee joint function scores between the two groups at 1 month and 3 months after surgery was sig-nificantly higher than that at 1 week after surgery,with statistical significance(P＜0.05).In addition,the knee joint func-tion scores in the observation group at 1 month and 3 months after surgery were significantly higher than those in the con-trol group,with statistical significance(P＜0.05).The difference in collaborative contraction rate and average energy fre-quency between the observation group and the control group at 7 days and 3 months after surgery were all statistically sig-nificant(P＜0.05).[Conclusion]The combination of Pro-kin balance system and BFR training can inhibit quadriceps atro-phy,promote knee joint function recovery,and is worthy of clinical promotion and application.
