The effect of Tai Chi exercise on motor function and sleep quality in patients with stroke: A meta-analysis.

PMID 31406759WHAT IT FOUND
Tai Chi added to usual care improved balance and daily activities in stroke patients, but did not improve walking speed or sleep quality.
The evidence is weak due to high variability between studies and short follow-up, so it should not replace standard rehab.
Key findings
01Tai Chi exercise significantly improved balance function and daily activity ability in stroke patients compared to control groups.
02Tai Chi did not show effective improvements on gait or walking ability, nor did it significantly improve sleep quality.
03The studies had high heterogeneity, meaning results varied widely between trials, and most lacked long-term follow-up or rigorous blinding.

What it does not show
High heterogeneity in the results for balance and walking means the studies varied widely in how they were done and what they found. Most included studies were short-term, so long-term effects are unknown. Blinding of participants and providers was not possible, and only half the studies described adequate randomization. The review included studies from both English and Chinese databases, which may introduce language bias or quality differences. Sleep quality data came from only three studies with 155 participants, which is too small to draw firm conclusions.

The easy way to misread this
Do not interpret the significant findings for balance and daily activities as proof that Tai Chi is superior to standard care. The high variability between studies and lack of long-term data mean the effect size is uncertain, and the null findings for walking and sleep are equally important.
