QUANTIFYING AXIAL ROTATION OF UPPER EXTREMITY SEGMENTS

Abstract

The calibrated anatomical systems technique (CAST) (Cappozzo et al, 1995) is an established method in gait and lower limb analyses. Its application to 6-degrees-of-freedom kinematic analyses and reduction of soft tissue artefact could make it particularly useful in quantifying axial rotation of the upper extremity. Such rotations have been established as being important in generating racket-head velocity in a variety of racket skills (Marshall and Elliott, 2000). The present study assesses the accuracy of CAST in quantifying the rotation of the forearm.
