Abstract

Objective: To refine the Graded and Redefined Assessment of Strength, Sensibility and Prehension (GRASSP) as a measure of upper limb impairment following cervical SCI. Method: A cross-sectional study assessed a cohort of neurologically stable patients with tetraplegia using a preliminary version of the GRASSP. Regression analysis was performed to determine the association between subcomponents of the GRASSP (impairment) and measures of function. The GRASSP was modified based on results. Results: Eliminated static two-point discrimination, tone, and one muscle. Conclusion: The GRASSP Version I consists of Semmes Weinstein monofilaments, manual muscle testing, and qualitative and quantitative prehension testing.
