Scientific Paper: Electrodiagnostic-guided Multimodal Management of Pediatric Spasticity: A Prospective Study on Objective Outcomes and Functional Gains

Objectives
Spasticity remains a complex and unresolved challenge in pediatric neurorehabilitation, with limited consensus on objective assessment and optimal treatment pathways.

This study aimed to (1) evaluate the utility of electrodiagnostic (EDX) techniques as objective tools for spasticity assessment and treatment guidance, and (2) assess the outcomes of current conservative and surgical interventions to inform evidence-based, patient-centered management strategies.



Design
A prospective, open-label study was conducted on 48 children with hypertonia. All participants underwent comprehensive evaluation including routine investigations, manual and instrumented physical assessments, and electrophysiological testing—specifically Hmax/Mmax and Fmax/Mmax ratios, alongside EMG recordings at rest and during voluntary movement.

Treatment modalities were tailored to spasticity severity:

Botulinum toxin type A (BTX-A) was administered to 23 children with moderate spasticity and no fixed contractures.
Selective dorsal rhizotomy (SDR) was performed in 8 children with severe spastic diplegia.
Multimodal management, combining selective peripheral neurotomy and orthopedic interventions, was applied to 17 children.
All patients participated in an intensive physical rehabilitation program with monthly follow-up over 12 months.

Results
Stretch reflex activity (Hmax/Mmax ratio) showed significant reduction at one month post-intervention, with a gradual increase thereafter, remaining below baseline levels.
BTX-A group demonstrated marked clinical improvement at one month, with sustained functional gains at six months.
Multimodal group achieved superior tone reduction and functional outcomes, though intergroup differences were statistically nonsignificant.
Changes in Hmax/Mmax ratio ratios and spontaneous EMG activity emerged as the most sensitive objective indicators for tracking therapeutic response.
Conclusions
Electrodiagnostic techniques provide a valid and accessible method for quantifying spasticity severity and tracking therapeutic response. BTX-A is effective in moderate spasticity (Hmax/Mmax < 0.5), while selective peripheral neurotomy combined with orthopedic management offer the most robust outcomes in complex presentations. This study supports an evidence-based, stratified approach to pediatric spasticity management, integrating neurophysiological metrics with individualized care.
