Abstract
Cerebral palsy is one of the main causes of disability in childhood. Resistive therapy has proved to be beneficial in increasing strength and motor function in these patients, but its impact on gait is not yet clear. To analyse the impact of resistive therapy on improving gait through a systematic review and meta-analysis. A search was conducted in Medline, ISI Web of Knowledge and PEDro for clinical trials in which resistive therapy was used and at least one gait parameter was assessed. Nine controlled studies and one single-arm study were identified. In terms of pre-post difference, the overall intragroup effect was in favour of the intervention, with null heterogeneity (standardised mean difference: 0.32; 95% CI: 0.19-0.44). The standardised mean differences were also positive as they restricted each of the gait parameters analysed: 0.36, 0.35 and 0.22 for step cadence, gait speed and step length, respectively. As regards the difference between groups, the results showed high heterogeneity, and the mean difference was also favourable, especially for speed (7.3 cm/s; 95% CI: 2.67-11.92), cadence (5.66 steps; 95% CI: 1.86-9.46) and, to a lesser extent, step length (3.25 cm; 95% CI: -1.69 to 8.19). The results support the impact of resistive therapy on gait improvement, especially in terms of the gait speed and step cadence parameters.
