GMFM supports reliable motor assessment in SMA; leaves open optimization of quantitative testing for weakest children.
Observational (n=12)
Gross motor function measures demonstrate high interrater reliability and may be more useful than quantitative muscle strength testing for clinical trials in childhood SMA.
Susan T. Iannaccone (2002) conducted an observational in Spinal muscular atrophy (n=12). Outcome measures assessment was evaluated on Interrater reliability of 4 outcome measures. Gross motor function measure demonstrated high interrater reliability in children with SMA, whereas quantitative muscle testing showed greater variability among the weakest children.
