OBJECTIVE: To determine the interrater reliability of the Neuromuscular Recovery
Scale (NRS), an outcome measure designed to classify people with complete or
incomplete spinal cord injury (SCI) into 4 phase-of-injury groups by assessing
motor performance based on normal preinjury function and disallowing use of
compensation for 4 treadmill-based items and 6 overground/mat items. DESIGN:
Masked comparison, multicenter observational study.
SETTING: Outpatient
rehabilitation. PARTICIPANTS: Raters (N=14) and a criterion standard expert
assigned scores to 10 video NRS assessments of persons with SCI. The raters were
volunteers from the NeuroRecovery Network. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: Interrater reliability measured with the Kendall coefficient of
concordance (W). RESULTS: Interrater reliability was generally strong (W=.91-.98;
95% confidence interval [CI], .65-.99), while lower reliability occurred for
treadmill stand retraining (W=.87; 95% CI, .06-1) and seated trunk extension
(W=.82; 95% CI, .28-.94). Less experienced raters assigned slightly lower scores
than the expert for most items, but the difference was less than half a point and
did not weaken concordance. CONCLUSIONS: NRS had strong interrater reliability, a
necessary first step in establishing its utility as a clinical and research outcome measure.
