By comparison, subjects with SMA-II who lost sitting ability (n = 10) had higher motor function, motor unit number estimate and compound motor action potential, longer survival, and later age when feeding or ventilation support was required. The mean rate of decline in The Children's Hospital of Philadelphia Infant Test for Neuromuscular Disorders motor function scale was 1.27 points/year (95% confidence interval 0.21–2.33, p = 0.02).Conclusions: Infants with SMA-I can be effectively enrolled and retained in a 12-month natural history study until a majority reach the combined endpoint. These outcome data can be used for clinical trial design.CHOP INTEND=The Children's Hospital of Philadelphia Infant Test for Neuromuscular Disorders; CI=confidence interval; CMAP=compound motor action potential; IQR=interquartile range; MUNE=motor unit number estimate; SMA=spinal muscular atrophy; SMN1=survival of motor neuron 1, telomeric
