Validity and Responsiveness of the Revised Nottingham Sensation Assessment for Outcome Evaluation in Stroke Rehabilitation

Abstract

OBJECTIVE: This study establishes the concurrent validity, predictive validity, and responsiveness of the Revised Nottingham Sensation Assessment (rNSA) during rehabilitation for people with stroke. METHOD: The study recruited 147 patients with stroke. The main assessment used was the rNSA, and outcome measures were the Fugl-Meyer Assessment sensory subscale (FMA-S) and motor subscale (FMA-M) and the Nottingham Extended Activities of Daily Living (NEADL) scale. RESULTS: Correlation coefficients were good to excellent between the rNSA and the FMA-S. The rNSA proprioception measure was a predictor for the FMA-S. The rNSA stereognosis and tactile-pinprick measures for the proximal upper limb were predictors for the FMA-M and the NEADL scale, respectively. Responsiveness was moderate to large for three subscales of the rNSA (standardized response mean = .51-.83). CONCLUSION: This study may support the concurrent validity, predictive validity, and responsiveness of the rNSA for people with stroke.
