Abstract

The purpose of this study was to investigate hand function evaluations. Factor analysis with varimax rotation was used to assess the fundamental characteristics of the items included in the Jebsen Hand Function Test and the Smith Hand Function Evaluation. The study sample consisted of 144 subjects with out disabilities and 22 subjects with Colles fracture. Results suggest a four factor solution: Factor I – pinch movement; Factor II – grasp; Factor III – target accuracy; and Factor IV – activities of daily living. These categories differentiated the subjects without Colles fracture from the subjects with Colles fracture. A hand function evaluation consisting of these four factors would be useful. Such an evaluation that can be used for current clinical purposes is provided.
