Pro-kin平衡系统联合血流限制训练对前交叉韧带重建术后患者膝本体感觉、膝关节功能及运动协调性的影响

The Effect of Pro-kin Balance System Combined with Blood Flow Restriction Training on Knee Proprioception,Knee Joint Function,and Motor Coordination in Patients after Anterior Cruciate Ligament Reconstruction Surgery

【目的】探讨Pro-kin平衡系统联合血流限制(blood flow restriction,BFR)训练对前交叉韧带重建术后患者膝本体感觉、膝关节功能及运动协调性的影响。【方法】选取2020年1月至2023年1月在本院行前交叉韧带重建术的82例患者,采用随机数字表法分为观察组和对照组,每组41例。对照组术后采用BFR训练,观察组术后在对照组基础上联合Pro-kin平衡系统训练。治疗3个月后,比较两组股四头肌横截面积、屈伸肌比值(H/Q)、相对峰力矩(PT/BW)、膝本体感觉指标、膝关节功能评分及运动协调性。【结果】观察组患者患侧股四头肌横截面积术后7 d与术后3个月差值小于对照组(P<0.05);观察组H/Q、PT/BW、30°位置偏差、60°位置偏差、协同收缩率、平均能量频率术后7 d与术后3个月差值均大于对照组(P<0.05)。两组膝关节功能评分术后1个月与术后3个月差值均显著高于术后1周,差异有统计学意义(P<0.05),且观察组术后1个月、术后3个月膝关节功能评分均显著高于对照组,差异均有统计学意义(P<0.05)。观察组协同收缩率差值、平均能量频率术后7 d与术后3个月差值均大于对照组,差异均有统计学意义(P<0.05)。【结论】Pro-kin平衡系统联合BFR训练治疗前交叉韧带重建术后患者,可抑制股四头肌萎缩,促进膝关节功能恢复,值得临床推广应用。

【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 ligament reconstruction surgery.【Methods】A total of 82 patients who underwent anterior cruciate ligament reconstruction surgery 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 postoperative BFR training,while the observation group received postoperative Pro-kin balance system training in addition to the control group.After 3 months of treatment,two groups were compared in terms of quadriceps cross-sectional area,flexor extensor ratio(H/Q),relative peak torque(PT/BW),knee proprioceptive index,knee joint function score,and motor coordination.【Results】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 frequency 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 significantly higher than that at 1 week after surgery,with statistical significance(P<0.05).In addition,the knee joint function scores in the observation group at 1 month and 3 months after surgery were significantly higher than those in the control group,with statistical significance(P<0.05).The difference in collaborative contraction rate and average energy frequency between the observation group and the control group at 7 days and 3 months after surgery were all statistically significant(P<0.05).【Conclusion】The combination of Pro-kin balance system and BFR training can inhibit quadriceps atrophy,promote knee joint function recovery,and is worthy of clinical promotion and application.
