Guillain-Barré syndrome (GBS) is a rare autoimmune disorder impacting the peripheral nervous system, particularly severe in children. This case series assesses the efficacy of paediatric rehabilitation on functional outcomes in paediatric GBS patients. The interventions focused on balance training, strength enhancement, and activities of daily living (ADLs). Four paediatric GBS patients were enrolled, presenting primarily with weakness and fever. Post-rehabilitation, significant enhancements were noted in motor function, ADLs, and quality of life (QoL). This series underscores the favourable impact of paediatric rehabilitation on GBS, advocating for early initiation to improve recovery and enhance QoL. GBS poses significant challenges, particularly in paediatric populations, necessitating comprehensive management strategies. While the syndrome's acute phase is managed medically, rehabilitation plays a pivotal role in optimizing long-term outcomes. This study aims to evaluate the effect of paediatric rehabilitation interventions on functional outcomes in children diagnosed with GBS. The four paediatric patients diagnosed with GBS underwent paediatric rehabilitation, comprising balance training, strength enhancement, and ADL exercises. Functional outcomes, including motor function, ADLs, and QoL, were assessed pre-and post-rehabilitation using standardized measures. The most common presenting symptoms in the paediatric GBS patients were weakness and fever. Following paediatric rehabilitation, significant improvements were observed in specific functional outcomes, including motor function, ADLs, and QoL. These improvements underscore the efficacy of paediatric rehabilitation in enhancing functional recovery and overall well-being in these patients. The findings of this case series emphasize the crucial role of paediatric rehabilitation in managing GBS in children. Early initiation of rehabilitation interventions may facilitate better recovery trajectories and improve long-term outcomes. Comprehensive rehabilitation strategies addressing motor function, ADLs, and QoL are essential components of holistic GBS management in pediatric patients. Pediatric rehabilitation interventions, encompassing balance training, strength enhancement, and ADL exercises, demonstrate significant benefits in improving functional outcomes in children with GBS. Early initiation of rehabilitation interventions is pivotal for enhancing the recovery process and optimizing the QoL in pediatric GBS patients. Further research is warranted to validate these findings and refine rehabilitation protocols for optimal outcomes.
