Computerized procedure for analyzing hand kinematics with a peg-moving task (Sarah-Pegworks)

This article describes Sarah-Pegworks, a computerized procedure for analyzing hand kinematics based on the peg-moving task. The procedure, developed in Visual Basic 6 programming language, includes (1) processing raw data from an infrared motion-tracking system, (2) identifying movement components, and (3) analyzing and presenting hand kinematic information in numerical and graphic outputs. Fifty-five normal adults set the parameters relative to filtering and movement identification. A case was presented to illustrate the clinical value of this procedure.
