对称负重式坐站转移训练对脑卒中后偏瘫患者 坐站转移稳定性和步态对称性的影响

Effects of symmetrical weight-bearing sit-stand transfer training on sit-stand transfer stability and gait symmetry in post-stroke hemiplegia patients

目的探讨对称负重式坐站转移训练对脑卒中后偏瘫患者坐站转移稳定性和步态对称性的影响。方法选择2019年2月至2022年2月江苏省淮安市第一人民医院收治的101例脑卒中后偏瘫患者,依照随机数字表法分为对照组(50例)与研究组(51例)。对照组接受常规双足平行位坐站转移训练,研究组接受对称负重式坐站转移训练,两组均持续训练4周。比较两组训练前后Breg平衡量表(BBS)、脑卒中生存质量量表(QOF)、改良Barthel指数量表(MBI)、步长偏差、患健侧摆动比值、健患侧支撑比值;比较两组训练后人体重心点在矢状面的最大摆动幅度(COGX)、从站到坐时间、从坐到站时间。结果训练后,两组BBS评分、QOF评分、MBI评分高于训练前,且研究组高于对照组(P<0.05);两组患健侧摆动比值、健患侧支撑比值及步长偏差均低于训练前,且研究组低于对照组(P<0.05)。研究组COGX高于对照组,从站到坐时间及从坐到站时间短于对照组(P<0.05)。结论对称负重式坐站转移训练可改善脑卒中后偏瘫患者平衡能力、生活质量、生活自理能力、坐站转移稳定性及步态对称性,并可缩短坐站转移时间。

Objective To investigate the effects of symmetrical weight-bearing sit-stand transfer training on sit-stand transfer stability and gait symmetry in post-stroke hemiplegia patients.Methods A total of 101 patients with post-stroke hemiplegia admitted to Huaian First People’s Hospital from February 2019 to February 2022 were selected,and they were divided into control group(50 cases)and study group(51 cases)according to the random number table method.The control group received conventional bipedal parallel sit-stand transfer training,and study group received symmetrical weight-bearing sit-stand transfer training.Both groups continued training for four weeks.Breg balance scale(BBS),stroke quality of life scale(QOF),modified Barthel index scale(MBI),step size deviation,the ratio of swing between sick and healthy sides,the ratio of support between healthy and sick sides before and after training were compared between two groups;the maximum swing of the body’s center of gravity on the sagittal plane(COGX),the time from standing to sitting,and the time from sitting to standing were compared between two groups after training.Results After training,the BBS score,QOF score,and MBI score of two groups were higher than those before training,and study group was higher than control group(P<0.05);the ratio of swing between sick and healthy sides,the ratio of support between healthy and sick side,and step size deviation of two groups were lower than those before training,and study group was lower than control group(P<0.05).COGX of study group was higher than that of control group,and the time from standing to sitting and the time from sitting to standing were shorter than those of control group(P<0.05).Conclusion Symmetrical weight-bearing sit-stand transfer training can improve the balance ability,quality of life,self-care ability,sit-stand transfer stability,and gait symmetry of post-stroke hemiplegia patients,and can shorten the sit-stand transfer time.
