Purpose: Preliminary validation of the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) for motor skill assessment in spinal muscular atrophy type I. Methods: A total of 27 subjects 3 to 260 months old (mean = 49, SD = 69) with spinal muscular atrophy-I were evaluated with the CHOP INTEND. Subjects were evaluated as part of a multicenter natural history study. Results: CHOP INTEND scores and age were significantly correlated (r = -0.51, P = .007; 2 survival of the motor neuron [SMN] 2 gene copies, n = 16, r = -0.60, 3 SMN2 gene copies, n = 9, r = -0.83). Respiratory support and CHOP INTEND scores were correlated (r = -0.74, P <.0001, n = 26). The CHOP INTEND and age regression in patients with 2 copies versus 3 copies of SMN2 approached significance (P = .0711, n = 25). Subjects who required respiratory support scored significantly lower (mean = 15.5, SD = 10.2 vs mean = 31.2, SD = 4.2, P <.0001, n = 27). Correlation with motor unit number estimation and combined motor unit activation were not significant. Conclusion: The CHOP INTEND reflects measures of disease severity and supports continued exploration of the CHOP INTEND. (Pediatr Phys Ther 2011; 23: 322-326)

The Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND): Test development and reliability

The motor skills of patients with spinal muscular atrophy, type I (SMA-I) are very limited. It is difficult to quantify the motor abilities of these patients and as a result there is currently no validated measure of motor function that can be utilized as an outcome measure in clinical trials of SMA-I. We have developed the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (" CHOP INTEND" ) to evaluate the motor skills of patients with SMA-I. The test was developed following the evaluation of 26 infants with SMA-I mean age 11.5. months (1.4-37.9. months) with the Test of Infant Motor Performance and The Children's Hospital of Philadelphia Test of Strength in SMA, a newly devised motor assessment for SMA. Items for the CHOP INTEND were selected by an expert panel based on item mean and standard deviation, item frequency distribution, and Chronbach's alpha. Intra-rater reliability of the resulting test was established by test-retest of 9 infants with SMA-I over a 2. month period; Intraclass correlation coefficient (ICC) (3,1) = 0.96. Interrater reliability was by video analysis of a mixed group of infants with neuromuscular disease by 4 evaluators; ICC (3,4) = 0.98 and in a group of 8 typically developing infants by 5 evaluators ICC (3,5) = 0.93. The face validity of the CHOP INTEND is supported by the use of an expert panel in item selection; however, further validation is needed. The CHOP INTEND is a reliable measure of motor skills in patients with SMA-I and neuromuscular disorders presenting in infancy. © 2009 Elsevier B.V.

The test of infant motor performance: reliability in spinal muscular atrophy type I
tone and motor problems; SMA1; tool development; scale development; TIMP
PURPOSE: The aim of this article was to determine reliability of the Test of Infant Motor Performance (TIMP) in infants with spinal muscular atrophy, type I (SMA-I). METHODS: Interrater reliability training was undertaken by 17 physical therapist evaluators using 6 infants with hypotonia and weakness (5 videotaped, 1 live). Eight trained evaluators then conducted a test-retest reliability study at their own center, performing 2 tests approximately 1 month apart on each of 11 infants with genetically confirmed SMA-I (5 boys, 6 girls; age range 37-501 days; 3 on pulmonary support). RESULTS: The interrater reliability training session had an overall weighted Kappa of 0.61 (95% confidence interval 0.59-0.63). For the test-retest reliability study, the intraclass correlation coefficient for the TIMP Total Score was 0.85 (95% confidence interval: 0.54-0.96). The test scores were not significantly different between the 2 sessions (Bradley-Blackwood test was nonsignificant). CONCLUSION: TIMP scores can be reliably obtained in infants with SMA-I.
