To evaluate the immediate and long-term effects of 12 weeks of Tai Chi training on dynamic balance and disease severity among individuals with cerebellar ataxia (CA). An assessor-blinded, two-arm, parallel-group randomized-controlled trial was conducted among 24 participants with CA. Participants were randomized to receive either Tai Chi intervention ( = 12) or usual care ( = 12). Dynamic balance was assessed using the Berg Balance Scale (BBS), Scale for the Assessment and Rating of Ataxia (SARA) balance sub-component of the SARA (SARAbal), Sensory Organization Test, and Limits of Stability test. Disease severity was assessed using the SARA and health-related quality of life using the EuroQol visual analog scale. Assessments were completed at baseline (week 0: T1), postintervention (week 12: T2), and at the end of the 24-week (week 36: T3) follow-up period. The 8-form Tai Chi exercise was delivered in 60-min sessions, three times a week for 12 weeks. Participants were asked to complete an unsupervised home Tai Chi exercise program over the next 24 weeks. Participants in the usual care control group completed all study measures but did not receive any intervention. Compared with the usual care control group, after 12 weeks of Tai Chi training, the experimental group demonstrated beneficial effects for dynamic balance assessed using the BBS (mean difference [MD]: 4, 95% confidence interval [CI]: -1.06 to 8.71) and the SARAbal (MD: -1.33, 95% CI: -2.66 to 2.33). The effect size ranged from small to large. The benefits gained were not sustained after 24 weeks during the follow-up assessment. Tai Chi did not benefit disease severity and health-related quality of life in this population. Some evidence supports the immediate beneficial effects of 12 weeks of Tai Chi training on the dynamic balance among individuals with CA.

评价 12 周太极拳训练对小脑性共济失调（CA）患者动态平衡和疾病严重程度的即时和长期影响。在 24 名 CA 患者中进行了一项评估员盲、双臂、平行组随机对照试验。参与者被随机分配接受太极拳干预（n=12）或常规护理（n=12）。使用 Berg 平衡量表（BBS）、共济失调评定量表（SARA）平衡分量表（SARAbal）、感觉组织测试和稳定性极限测试评估动态平衡。使用 SARA 和 EuroQol 视觉模拟量表评估疾病严重程度和健康相关生活质量。评估在基线（第 0 周：T1）、干预后（第 12 周：T2）和 24 周（第 36 周：T3）随访期间完成。8 式太极拳运动在 60 分钟的课程中进行，每周 3 次，共 12 周。参与者被要求在接下来的 24 周内完成一项非监督的家庭太极拳锻炼计划。常规护理对照组的参与者完成了所有研究措施，但未接受任何干预。与常规护理对照组相比，12 周的太极拳训练后，实验组在使用 BBS（平均差异 [MD]：4，95%置信区间 [CI]：-1.06 至 8.71）和 SARAbal（MD：-1.33，95% CI：-2.66 至 2.33）评估的动态平衡方面表现出有益的效果。效应大小从小到大。在随访评估中，24 周后的随访期间，这些益处并未持续。太极拳对该人群的疾病严重程度和健康相关生活质量没有益处。有一些证据支持 12 周太极拳训练对 CA 患者动态平衡的即时有益影响。澳大利亚新西兰临床试验注册中心（ACTRN12617000327381）。
