Abstract

The purpose of this study was to identify differences between two established methods for wrist angle calculation (U.L.E.M.A. by Jaspers et al. & model by Metcalf et al.) during range of motion (ROM) movement tasks. Reflective markers, representing both hand models, were placed on anatomical landmarks of 10 healthy participants. Sagittal plane ROM of the wrist was analysed during open and closed hand wrist flexion/extension. Differences in ROM of the wrist flexion/extension were found for both tasks over the entire movement cycle (closed hand=12.4° (±10.1), open hand=10.3° (÷7.0°)). In particular, differences in extension are noticeable during wrist movement with open hand, though, an offset correction in neutral position might influence this outcome. Potential reasons for these variances are identified and should be taken into account when utilizing the hand model.
