Home-Based Exercise for Improving Balance Ability in Post-Stroke Patients: A Systematic Review and Meta-Analysis.

Background: Home-based exercise offers a cost-effective way to receive thorough rehabilitation without the requirement of costly supervised treatment.

Aim: To investigate the effects of home-based exercise on the balance ability in post-stroke patients.

Methods: A thorough search was carried out on various databases, such as Cochrane Library, Web of Science, PubMed, Embase, and China National Knowledge Infrastructure Library, until October 2024. The inclusion criteria were limited to randomized controlled trials that evaluated the impact of home-based exercise interventions.

Results: The meta-analysis indicated that home-based exercise significantly improved static balance ability (Berg Balance Scale [BBS]: MD = 3.45, 95% CI [1.43, 5.47], I = 71%, p = 0.0008, random-effects model). Conversely, the analysis revealed that the home-based exercise group did not exhibit a statistically significant improvement in the Time up and Go Test (TUG) when compared to the control group (TUG: MD = -0.34, 95% CI [-4.30, 3.61], I = 96%, p = 0.86, random effects model). The subgroup analysis revealed that home-based exercise significantly enhanced balance ability in patients with subacute stroke (BBS: p < 0.0001; TUG: Overall effect p = 0.02). However, no significant improvement was observed in patients with chronic stroke (BBS: p = 0.39). Regarding the duration of intervention, both short-term and long-term interventions were effective on the BBS (p < 0.0001 and p = 0.0008, respectively), although no significant difference was found for the TUG. Participants engaging in exercise for more than 90 min per week demonstrated greater improvements in balance ability (BBS: p < 0.0001; TUG: p = 0.02). When considering national economic levels, significant effects on the BBS were observed in both developed and developing countries (p = 0.0001 and p < 0.0001, respectively), while significant effects on the TUG were noted only in developing countries (p = 0.04).

Linking Evidence To Action: Home-based exercise interventions showed significant results in improving static balance in patients with subacute stroke, especially home-based exercise that lasted longer than 12 weeks and lasted at least 90 min per week. However, more methodologically rigorous randomized controlled trials are needed to validate these results. In addition, the optimal exercise program and type to optimize the balance ability of stroke patients also need further research.
