Functional outcomes of botulinum neurotoxin-A injection followed by reciprocal electrical stimulation in children with cerebral palsy: A randomized controlled trial

Abstract

Background: The integration of therapeutic approaches is increasingly recommended for children with cerebral palsy, to enhance outcomes. Nevertheless, clinicians still opt for separate or combined therapies based on little credible knowledge. Objective: This study endeavored to evaluate the effect of botulinum neurotoxin-A (BoNT-A) injection and reciprocal neuromuscular electrical stimulation (rNMES) and their combination on the upper extremity function in children with spastic hemiplegia. Methods: Sixty-four children with spastic hemiplegia (aged 6– 10 years) were randomly assigned to four treatment-based groups [group I (BoNT-A), group II (rNMES), group III (combined BoNT-A and rNMES), and group IV (Control)]. All children received a physical rehabilitation program, thrice/week over three months. Unilateral upper-limb function, bimanual hand function, and real-time arm-hand function were assessed using Melbourne Assessment (MA), Assisting Hand Assessment (AHA), and Pediatric Motor Activity Log (PMAL) scales respectively pre-treatment, post-treatment, and at 6 months follow-up. Results: Post-treatment, group III achieved greater improvement in MA, AHA, and PMAL compared to other groups (all P < 0.05), and the difference remained in favor of group III at the follow-up (all P < 0.05). Conclusions: This study suggests that BoNT-A and rNMES combined are more effective than either of them alone to enhance upper-extremity function in children with spastic hemiplegia.
