Effects of backward gait training on balance, gross motor function, and gait in children with cerebral palsy: a systematic review

Abstract

Objective: To investigate the effects of backward gait training on balance, gross motor function, and gait parameters in children with cerebral palsy. Data sources: PubMed, Cochrane Library, Web of Science, Science Direct, Physiotherapy Evidence Database (PEDro), and Google Scholar were searched up to May 2018. Review methods: Randomized controlled trials were included if they involved any form of backward gait training for children with cerebral palsy. Two authors independently screened articles, extracted data and assessed the methodological quality using PEDro scale, with any confliction resolved by the third author. Modified Sackett Scale was used to determine the level of evidence for each outcome. Results: Out of 1492 papers screened, 7 studies with 172 participants met the inclusion criteria. The duration of treatment ranged from 15 to 25\u2009minutes, three times a week and for 6–12\u2009weeks. The quality of studies ranged from good (two studies) to fair (four studies) and poor (one study), with a mean PEDro score of 4.7 out of 10. All included studies showed positive effects in the measured outcomes. The results showed level 1b evidence for balance when compared to no intervention, and for gross motor function, step length and walking speed when compared to same dose of forward gait training. The clinical heterogeneity of studies makes meta-analysis inappropriate. Conclusion: In children with cerebral palsy, there is moderate evidence that backward gait training improves balance, gross motor function, step length and walking velocity. More high-quality studies are needed.
