Effect of Motor Development, Motor Function and Electrophysiologic Findings of IOPD Under ERT

Background Pompe disease is an autosomal recessive disease, enzyme replacement therapy (ERT) and new born screen (NBS) had been initiated in Taiwan since 2008. However, residual muscle weakness were noted. Decrease in amplitude of nerve compound muscle action potential (CMAP) and increase spontaneous activity were reported before the imitation of ERT. However, the motor development, motor function and electrodiagnostic presentation which were important in further direction of treatment and rehabilitation program arrangement in infantile Pompe disease (IOPD) under ERT is lacking. Aim To investigate the motor development, motor function and electrodiagnostic presentation in IOPD under ERT. Method This is an observational, prospective, longitudinal, follow-up study. Motor development was assessed by Alberta Infant Motor Scale (AIMS) and Peabody Developmental Motor Scales, Second Edition (PDMS II); motor function was assessed by Pediatric Evaluation of Disability Inventory (PEDI) and Gross Motor Function Measure (GMFM). Electrodiagnosis studies include nerve conduction study (NCS) and electromyography (EMG). Expect Effects Obtain the characteristics of motor development, motor function and electrodiagnosis presentation of IOPD under ERT, and the relation between motor development, motor function and electrodiagnosis presentation.
