What was done
A systematic review and meta-analysis of six databases (PEDro, PubMed/Medline, CENTRAL, Scopus, Embase, and Web of Science) evaluated the effects of community-based exercise (including dance, Chinese martial arts, Nordic walking, and home-based exercise) compared to usual care in Parkinson's disease. The primary outcome was UPDRS-III score. Pooled mean differences (MD) with 95% confidence intervals were calculated, and subgroup/meta-regression analyses assessed exercise parameters and moderating factors.
What was found
Twenty-two studies with 809 total participants were analyzed. Community-based exercise significantly improved multiple motor and mobility metrics: - UPDRS-III: MD = -5.83 (95% CI, -8.29 to -3.37) - Total UPDRS: MD = -7.80 (95% CI, -10.98 to -6.42) - Timed Up and Go test: MD = -2.22 (95% CI, -3.02 to -1.42) - 6-Minute Walk Test: MD = 68.81 (95% CI, 32.14 to 105.48) - Berg Balance Scale: MD = 4.52 (95% CI, 2.72 to 5.78) Significant between-study heterogeneity was observed. Age, weekly frequency, and treatment duration influenced outcomes; the most common effective regimen was 60 minutes twice weekly of tango or tai chi.
Why it matters
Community-based exercise programs offer practical, non-clinical interventions that meaningfully improve Parkinson's motor symptoms, balance, and gait without requiring specialized clinical facilities.
Limits
Total sample size was modest (averaging ~37 participants per study), and between-study heterogeneity was marked. The abstract does not specify whether all included trials were randomized, nor does it report long-term follow-up after the interventions ended.
