Clinical use of neuromuscular electrical stimulation for children with cerebral palsy, Part 1: Lower extremity
Insights
Neuromuscular electrical stimulation (NMES) improved walking and running in young children with cerebral palsy. This therapy showed functional gains and carryover effects, suggesting NMES is a valuable physical therapy adjunct.
Area of Science:
- Pediatric Physical Therapy
- Neurorehabilitation
- Motor Learning in Cerebral Palsy
Background:
- Cerebral palsy (CP) often impairs motor function, particularly in children with hemiplegia.
- Traditional physical therapy aims to improve functional mobility in children with CP.
- Exploring adjunct therapies like Neuromuscular Electrical Stimulation (NMES) is crucial for enhancing outcomes.
Observation:
- Three male children (1.6, 6.7, 10 years) with hemiplegic CP received NMES.
- NMES was applied to the lower extremities combined with a task-oriented motor learning approach.
- Children tolerated NMES well, with some demonstrating functional carryover post-treatment.
Findings:
- The youngest child exhibited immediate improvements in symmetrical walking and running.
- Older children showed significant, unexpected gains in locomotor efficiency.
- Physiological Cost Index (PCI) improved significantly, indicating enhanced walking economy.
Implications:
- NMES shows promise as an effective adjunct therapy for pediatric cerebral palsy.
- This approach may accelerate functional gains and improve motor learning in children with CP.
- Further research is warranted to confirm NMES efficacy in larger pediatric CP populations.
Abstract:
This report, part 1 of a two-part case report on the clinical use of neuromuscular electrical stimulation (NMES) for children with cerebral palsy, documents the functional changes that occurred with the application of NMES to the lower extremity of three male children, 1.6, 6.7, and 10 years of age, all with hemiplegia due to cerebral palsy. Neuromuscular electrical stimulation was used in conjunction with a dynamic-systems, task-oriented model of motor learning. The children tolerated NMES well and at times demonstrated carryover after the removal of NMES. The youngest child showed immediate change in the ability to walk and run symmetrically. The two older boys demonstrated significant improvement in locomotor efficiency in a short time, although they were of an age when this improvement was not expected. One boy's Physiological Cost Index (PCI) measurement (a measure of locomotor efficiency) improved fourfold, and the other boy's PCI measurement improved by a factor of two. The results show preliminary evidence for the usefulness of NMES as an adjunct to the physical therapy program for improving function in children with cerebral palsy.
