RESUMO
Many reviews have shown that low muscle strength causes the greatest limitations compared to spasticity in motor function in children with CP, shifting the focus from spasticity management towards strength training for these children. The most recent analysis including strength training intervention found sufficient evidence in children with Cerebral palsy. So physical therapists, doctors and parents need to understand and gain knowledge of the effects of the widely used strength training techniques in physical therapy for evidence based decision-making. This review aimed to document the accuracy and effectiveness of strength training in children with Cerebral Palsy [CP]. This systematic review included all studies that investigated outcomes of strength training, used separately or in combination in children younger than 21 years old with cerebral palsy. These reviews were identified in Medline, Cinahl, PEDro and the Cochrane library. The two reviewers independently assessed the methodological quality and extracted the data. This study identified a total of 36 articles from which the 33 articles retrieved met the search criteria. The level of evidence was found from Fair to Good [II to V in Sackett's level of evidence]. The results from this review indicate that the levels of evidence for strengthening in children with CP have improved; however, further high-level evidence is required for strength intervention
