Tailored Sitting Tai Chi Program for Subacute Stroke Survivors: A Randomized Controlled Trial.

Abstract

The initiation of exercise during rehabilitation at the subacute stage could provide stroke survivors with an approach to recovery that capitalizes on unique physiological conditions and promotes spontaneous recovery. We aimed to examine the effects of a tailored sitting Tai Chi program on recovery outcomes among subacute stroke survivors. We conducted a 12-week assessor-blind randomized controlled trial in China. Subacute stroke survivor-caregiver dyads were recruited and randomly assigned to either the sitting Tai Chi group (n=80) or attention control group (n=80). Outcomes including upper limb function (Fugl-Meyer Assessment Upper Extremity & Wolf Motor Function Test), balance control (Berg Balance Scale), sitting balance control (Trunk Impairment Scale), depressive symptoms (Geriatric Depression Scale Short Form), shoulder range of motion, shoulder pain (ShoulderQ), activities of daily living (Modified Barthel Index), and quality of life (Stroke Specific Quality of Life Scale) were measured at baseline, in-process, immediately post, and 4-week postintervention. Immediately postintervention, the sitting Tai Chi group (n=69) showed significant upper limb function improvement in the primary outcomes including the performance time (regression coefficient of the group-by-time interaction, B=-21.415 [95% CI, -31.000 to -11.831]) and functional ability (B=10.146 [95% CI, 4.886-15.406]) domains of the Wolf Motor Function Test, balance control (B, 4.972 [95% CI, 1.356-8.588]), and sitting balance control (B=4.397 [95% CI, 2.699-6.096]). Compared with the control group (n=65), improvements were also observed in secondary outcomes including depressive symptoms (B=-1.626 [95% CI, -2.304 to -0.948]), shoulder extension (B=4.518 [95% CI, 0.893-8.144]), activities of daily living (B=5.510 [95% CI, 0.450-10.569]), and quality of life (B=15.680 [95% CI, 7.255-24.105]). The results support the effectiveness of a tailored sitting Tai Chi program in improving recovery outcomes among subacute stroke survivors and provide additional knowledge to support the clinical implementation of such a program.
