Effects of home-based exercise interventions on post-stroke depression: A systematic review and network meta-analysis.

Depression after stroke is common and can slow recovery, so researchers have been looking for treatments beyond medication that people can do at home. This review pooled evidence from several small randomized trials testing different types of home-based exercise, including mind-body practices like Tai Chi, flexibility or neuro-motor skills training, and aerobic exercise, to see which approach helped most with post-stroke depression scores measured right after treatment. Across a network comparison of nine trials, mind-body exercise ranked as the most promising option, with Tai Chi standing out within that category. Flexibility training and aerobic exercise showed smaller, less consistent effects.

The authors themselves describe the overall certainty of this evidence as very low, meaning these results point to a possible direction rather than a settled answer, and larger, more rigorous trials are needed before drawing firm conclusions about which exercise works best.

If you or someone you care about has experienced depression after a stroke, you may already know that treatment options can feel limited. This review looked at whether exercise programs done at home might help ease that depression, comparing different styles like gentle mind-body practices such as Tai Chi, flexibility and coordination training, and aerobic exercise. Pooling results from nine small trials involving 517 people total, the researchers found that mind-body exercise, and Tai Chi in particular, showed the most promising results for reducing depression symptoms.

Flexibility training and aerobic exercise showed smaller effects that were less clear. It's important to understand that the researchers rated the overall quality of this evidence as very low certainty. That means these findings are an early signal worth watching rather than a proven answer, and more solid research is needed to confirm whether home-based exercise, and which type, truly helps with depression after stroke.

This network meta-analysis pooled nine randomized controlled trials (n=517) comparing home-based exercise modalities for post-stroke depression, using post-treatment depression scores as the primary endpoint. Mind-body exercise ranked highest by surface under the cumulative ranking curve (SUCRA 90.4%, Hedges' g -0.59, 95% CI -1.16 to -0.02), followed by flexibility/neuro-motor skills training (SUCRA 42.9%, g -0.10, CI -0.70 to 0.49) and aerobic exercise (SUCRA 39.3%, g -0.07, CI -0.81 to 0.67), the latter two showing effects that did not reliably exclude no difference.

A subgroup analysis within mind-body interventions identified Tai Chi as most effective (SUCRA 99.4%, g -0.94, CI -1.28 to -0.61). The authors explicitly rate the certainty of this evidence as very low, reflecting the small number and size of included trials, and likely heterogeneity and risk-of-bias concerns typical of exercise intervention research assessed with RoB-2. Network meta-analysis allows indirect ranking across interventions not all directly compared, but this does not substitute for direct head-to-head trials.

Adverse events were not reported in the abstract. The authors call for multicenter trials against no-intervention controls examining dose, reach, fidelity, and long-term outcomes before these findings inform practice.
