简易膝关节训练器对脑卒中偏瘫患者膝关节屈曲主动运动的疗效

Effect of simple knee trainer on knee active flexion for hemiplegics after stroke

目的观察简易膝关节训练器改善脑卒中偏瘫患者膝关节屈曲主动运动的临床疗效。方法2020年3月至2021年5月,选择本院46例脑卒中后偏瘫患者,随机分为对照组和试验组各23例。两组均接受常规康复训练,试验组增加用简易膝关节训练器坐位下行膝关节屈曲主动运动训练,共8周。训练前、后测量坐位膝关节主动屈曲角度和Holden步行功能分级,采用步态分析系统测量摆动时膝关节屈曲最大角度。结果训练后,两组膝关节主动活动度及步行中摆动期膝关节最大屈曲角度均显著提高(|t|>6.991,P<0.001),且试验组提高更多(t>2.185,P<0.05);两组Holden步行功能分级均明显提高(|Z|>2.828,P<0.01),两组间无显著性差异(Z=-0.821,P=0.412)。结论应用简易膝关节训练器训练能有效改善膝关节主动屈曲活动度,可在临床和社区康复中应用。

Objective To observe the clinical efficacy of simple knee trainer on active knee flexion in patients with hemiplegia after stroke.Methods From March,2020 to May,2021,46 hemiplegics after stroke in Beijing Bo'ai Hospital were randomly divided into control group(n=23)and experimental group(n=23).Both groups accepted routine rehabilitation training,and the experimental group accepted knee flexion exercise training in sitting position through the simple knee trainer,for eight weeks.They were measured active knee flexion angle in sitting position and maximum flexion angle in walking before and after training,as well as Holden Functional Ambulation Category(FAC).Results Both active knee flexion angle in sitting position and maximum flexion angle in walking significantly increased in both groups after training(|t|>6.991,P<0.001),and increased more in the experimental group than in the control group(t>2.185,P<0.05).The grade of FAC also improved in both groups(|Z|>2.828,P<0.01),and no significant difference was found between groups(Z=-0.821,P=0.412).Conclusion The application of simple knee trainer can effectively improve the active range of motion of knee,which may be used in clinic-and community-based rehabilitation.
