Hemiplegia patients in the convalescent period of stroke generally have gait, balance dysfunction and the risk of falling, which seriously affects their daily living ability and prognosis. Traditional exercise therapy such as Tai Chi can play its unique advantages as an intervention, but there are different practice routines and insufficient evidence of evidence-based medicine, which limit its clinical application.

To observe the effect of modified Tai Chi on the disorder of gait and balance and fall efficacy in patients with hemiparesis in convalescent stage of stroke.

A total of 68 patients with hemiplegia in the convalescent stage of stroke who were admitted to the Second Affiliated Hospital of Heilongjiang University of Chinese Medicine from June 2020 to July 2021 were selected and divided into an observation group (n=34) and a control group (n=34) by random number table method. On the basis of routine rehabilitation treatmentonboth groups, the control group received motor relearning program (MRP) , whereas the observation group received modified Tai Chi intervention, once a day, 30 min a time, and 5 days a week, for 8 weeks. The two groups were assessed before and after the intervention using Fugl-Meyer assessment of lower extremity (LE-FMA) , 6-min walking test (6MWT) , Berg Balance Scale (BBS) , timed up and go test (TUGT) , modified Barthel index (MBI) , step length, frequency and speed, and modified fall efficacy scale (MFES) .

One case dropped out in the observation group, and a total of 33 cases were included, while there was no dropout in the control group, and a total of 34 cases were included. There was no significant difference between the two groups on the results of LE-FMA, 6MWT, BBS, TUGT, MBI, step length, frequency and speed, and MFES before the treatment (P>0.05) . No significant difference was found in TUGT time and step length between the two groups after the treatment (P>0.05) . However, after the treatment, LE-FMA, BBS, MBI, MFES scores, step frequency and speed in the observation group were higher than those in the control group, and 6MWT walking distance was longer (P<0.05) . Furthermore, LE-FMA, BBS, MBI, MFES scores, step frequency and speed after treatment were higher than those before treatment, 6MWT walking distance was longer and TUGT time was shorter than that before treatment (P<0.05) .

Modified Tai Chi can effectively improve gait and balance disorder and fall efficacy in patients with hemiparesis in the convalescent stage of stroke.

脑卒中恢复期偏瘫患者普遍存在步态、平衡功能障碍和跌倒风险，严重影响患者日常生活能力和预后。太极拳等传统运动疗法作为干预措施可发挥其独特优势，但存在习练套路各异，循证医学证据不足等现象，限制了临床推广应用。

观察改良太极功法对脑卒中恢复期偏瘫患者步态平衡及跌倒效能的改善效果。

选取2020年6月至2021年7月黑龙江中医药大学附属第二医院收治的脑卒中恢复期偏瘫患者68例，采用随机数字表法分为观察组（n=34）和对照组（n=34）。在两组均接受常规治疗的基础上，对照组进行运动再学习训练，观察组进行改良太极功法训练，1次/d，30 min/次，5 d/周，共8周。比较两组治疗前后Fugl-Meyer运动功能评分量表的下肢部分（LE-FMA）评分、6 min步行试验（6MWT）步行距离、Berg平衡量表（BBS）评分、计时起立-行走测试（TUGT）用时、改良Barthel指数（MBI）评分、步长、步频、步速及修订版跌倒效能量表（MFES）评分。

观察组脱落1例，共纳入33例，对照组无脱落，共纳入34例。治疗前，两组患者LE-FMA、BBS、MBI、MFES评分，6MWT步行距离，TUGT用时及步长、步频、步速比较，差异均无统计学意义（P>0.05）。治疗后，两组患者TUGT用时、步长比较，差异均无统计学意义（P>0.05）。治疗后，观察组LE-FMA、BBS、MBI、MFES评分及步频、步速均高于对照组，6MWT步行距离长于对照组（P<0.05）。两组患者治疗后LE-FMA、BBS、MBI、MFES评分，步长、步频、步速均高于治疗前，6MWT步行距离长于治疗前，TUGT用时短于治疗前（P<0.05）。

改良太极功法可有效改善脑卒中恢复期偏瘫患者的步态、平衡功能以及跌倒效能。
