Abstract
Background
Hybrid Assistive Limb (HAL) is a movement support robot that assists the walking function of patients with diseases causing muscle weakness in the lower limbs.
Intrathecal baclofen (ITB) therapy exerts positive effects on muscle tone in children with severe spasticity who have difficulty walking.
The present case report describes a child with spastic paraplegia who underwent intensive robotic rehabilitation with HAL and combined ITB therapy.
Case
A 14-year-old boy with spastic paraplegia from Pelizaeus-Merzbacher disease was undergoing treatment with oral muscle relaxants and botulinum toxin A. However, the medications were ineffective and his spasticity was progressing. A baclofen infusion pump was implanted with the catheter tip at the T10 level and ITB therapy was started. A regimen of 12.5 μg/day dose of baclofen was administered and his spasticity of limbs and trunk were attenuated. Walking practice using HAL was performed under spasticity relief by ITB therapy and gait function and patterns, excluding endurance, were improved. The attenuation of spasticity by ITB therapy made “Lying, Rolling and Sitting” easier for the patient, but may have affected “Standing”, which was supported using spasticity, and also affected the Caregiver Assistance Scale of the Mobility domain of the Pediatric Evaluation of Disability Inventory (PEDI). While, the amount of assistance required for the Activities of Daily Living (ADLs) related to self-care and the overall caregiver burden both decreased.
Conclusion
This is the first case report to demonstrate the efficacy and safety of combined ITB therapy and HAL rehabilitation in an ambulatory pediatric patient.
