An accessible and reliable motor function assessment tool can be achieved by joining clinical scales and motion tracking devices. The Motor Function Measure (MFM) scale is composed of 32 items and validated for patients aged from 6 to 60 years with neuromuscular diseases. Its application is unquestionable for clinical monitoring of patients. In order to reduce scoring variability in the evaluation process and increase patient involvement during MFM application , this work proposes a system prototype capable of capturing, recording and evaluating patient movements based on Kinect and Tablet technologies. An animation system based on a progressive narrative adapted to the MFM scale was also implemented.
