As a new means of rehabilitation, blood flow restriction training (BFRT) is widely used in the field of musculoskeletal rehabilitation. To observe whether BFRT can improve the efficacy of routine rehabilitation intervention in patients with chronic ankle instability (CAI). Twenty-three patients with CAI were randomly divided into a routine rehabilitation group (RR Group) and a routine rehabilitation + blood flow restriction training group (RR + BFRT Group) according to the Cumberland Ankle Instability Tool (CAIT) score. The RR Group was treated with routine rehabilitation means for intervention, and the RR + BFRT Group was treated with a tourniquet to restrict lower limb blood flow for rehabilitation training based on routine training. Before and after the intervention, the CAIT score on the affected side, standing time on one leg with eyes closed, comprehensive scores of the Y-balance test, and surface electromyography data of tibialis anterior (TA) and peroneus longus (PL) were collected to evaluate the recovery of the subjects. Patients were followed up 1 year after the intervention. After 4 weeks of intervention, the RR + BFRT Group CAIT score was significantly higher than the RR Group (19.33 VS 16.73, < 0.05), the time of standing on one leg with eyes closed and the comprehensive score of Y-balance were improved, but there was no statistical difference between groups ( > 0.05). RR + BFRT Group increased the muscle activation of the TA with maximum exertion of the ankle dorsal extensor ( < 0.05) and had no significant change in the muscle activation of the PL with maximum exertion of the ankle valgus ( > 0.05). There was no significant difference in the incidence of resprains within 1 year between the groups (36.36% VS 16.67%, > 0.05). The incidence of ankle pain in the RR + BFRT Group was lower than that in the RR Group (63.64% VS 9.09%, < 0.01). Therefore, four-weeks BFRT improves the effect of the routine intervention, and BFRT-related interventions are recommended for CAI patients with severe ankle muscle mass impairment or severe pain.
作为一种新的康复手段，血流限制训练（BFRT）在肌肉骨骼康复领域得到广泛应用。为观察BFRT能否提高慢性踝关节不稳（CAI）患者常规康复干预的疗效。根据坎伯兰踝关节不稳工具（CAIT）评分，将23例CAI患者随机分为常规康复组（RR组）和常规康复+血流限制训练组（RR+BFRT组）。RR组采用常规康复手段进行干预，RR+BFRT组在常规训练基础上使用止血带限制下肢血流进行康复训练。干预前后，收集患侧CAIT评分、闭眼单腿站立时间、Y平衡测试综合评分以及胫骨前肌（TA）和腓骨长肌（PL）的表面肌电图数据，以评估受试者的恢复情况。干预后对患者进行1年随访。干预4周后，RR+BFRT组CAIT评分显著高于RR组（19.33对16.73，<0.05），闭眼单腿站立时间和Y平衡综合评分有所改善，但组间无统计学差异（>0.05）。RR+BFRT组在踝关节背伸最大用力时TA的肌肉激活增加（<0.05），在踝关节外翻最大用力时PL的肌肉激活无显著变化（>0.05）。两组1年内再次扭伤的发生率无显著差异（36.36%对16.67%，>0.05）。RR+BFRT组踝关节疼痛的发生率低于RR组（63.64%对9.09%，<0.01）。因此，四周的BFRT可改善常规干预效果，对于踝关节肌肉量严重受损或疼痛严重的CAI患者，建议采用与BFRT相关的干预措施。
