Interrater Reliability of the Pediatric Neuromuscular Recovery Scale in Children with Spina Bifida.

Purpose: The purpose of this study was to examine the interrater reliability of the Pediatric Neuromuscular Recovery Scale (Peds NRS) to classify motor capacity in children with myelomeningocele (MMC) form of spina bifida.

Methods

Twenty-one children with MMC (1.5-10 years of age) were each scored on the Peds NRS three times: two live testing sessions and one video recorded session. Every child was scored by two physical therapists and one occupational therapist. Interrater reliability was analyzed using intraclass correlation coefficients (ICC) for individual items and the summary score.

Results

Strong interrater reliability was determined for the overall Peds NRS score (ICC = 0.89; 95% CI, .80-.95). Eleven of 16 individual items exhibited good to excellent reliability (ICC ≥ 0.80). Pediatric clinicians were able to reliably administer and score the Peds NRS on children with MMC, representing a wide range of ages and functional levels.
