摘　　要：目的探究等速肌力训练对脑卒中后偏瘫患者上肢的影响。方法选取2022-07—2023-07石家庄市人民医院收治的99例脑卒中后偏瘫患者,采用随机数字法分为常规组49例和观察组50例,常规组给予常规康复治疗,观察组在常规康复治疗基础上给予等速肌力训练。比较训练前和训练4周后,2组患者运动皮层兴奋性[患侧半球运动诱发电位(MEP)潜伏期、中枢运动传导时间(CMCT)]、手力量、生活自理能力[改良Barthel指数量表(MBI)]。结果训练4周后,2组患者MEP、CMCT较训练前降低,观察组MEP[(14.57±1.25)ms]、CMCT[(8.29±1.03)ms]低于常规组[(15.86±1.32)ms、(8.96±1.06)ms](P<0.05);2组患者握力及MBI评分均较训练前升高,观察组握力[(22.42±2.38)kg]、MBI评分[(62.78±6.33)分]高于常规组[(20.15±2.24)kg及(60.17±6.21)分](均P<0.05)。结论等速肌力训练能够改善运动皮层兴奋性,增强手力量,提高生活自理能力。Objective To investigate the effect of isokinetic muscle strength training on upper limb of patients with post-stroke hemiplegia.Methods Totally 99 patients with post-stroke hemiplegia treated in Shijiazhuang People’s Hospital from July 2022 to July 2023 were selected and divided into conventional group(49 cases)and observation group(50 cases)by the random number method.The conventional group was given conventional rehabilitation treatment,and the observation group was given isokinetic muscle strength training on the basis of conventional rehabilitation treatment.Before training and after 4 weeks of training,the two groups were compared in terms of motor cortex excitability(affected hemisphere motor evoked potential(MEP)latency,central motor conduction time(CMCT)),hand strength and self-care ability of daily living(modified Barthel index(MBI)).Results After 4 weeks of training,the MEP and CMCT were reduced compared with those before training,and the above indicators with(14.57±1.25)ms and(8.29±1.03)ms in observation group were lower compared with(15.86±1.32)ms and(8.96±1.06)ms in conventional group(P<0.05).The grip strength and MBI score in both groups were enhanced compared with those before training,and the above indicators with(22.42±2.38)kg and(62.78±6.33)points in observation group were higher than(22.42±2.38)kg and(62.78±6.33)points in conventional group(all P<0.05).Conclusion Isokinetic muscle strength training can improve the motor cortex excitability,strengthen the hand strength and increase the self-care ability of daily living.
