Neuromodulation techniques for enhancing lower extremity motor function in children with cerebral palsy (CP): a systematic review and meta-analysis of repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) interventions

Comprehensive Summary

The study examines whether noninvasive neuromodulation techniques, such as repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), can improve gait and related functions in children with cerebral palsy. They conducted a review and meta-analysis of controlled trials that were randomly identified through many databases, including 21 cerebral palsy patients receiving rTMS or tDCS. Meta-analysis results showed that tDCS had improved gait velocity significantly, gross motor function, and functional independence. However, effects on step and stride length were not statistically significant. rTMS was associated with improved overall motor function, performance across many studies. The authors conclude that both are safe and effective, demonstrating promise for enhancing motor outcomes, but limited neuroimaging data and heterogeneity could constrain conclusions.

Outcomes and Implications

The research is important because gait impairment is a major symptom of their disability and severely reduces the quality of life among children with cerebral palsy, and rehabilitation strategies often result in incomplete recovery. They found that tDCS and rTMS possibly serve as an effective therapy to conventional rehabilitation by selectively enhancing motor function without any major safety concerns. These neuromodulation techniques are relevant because of their noninvasive nature and compatibility with existing physical therapy programs, making them reasonable to integrate into rehabilitation settings. The authors agree that more standardized long-term trials with neuroimaging are needed to establish broader clinical adoption.
