Abstract
Background: Many clinical studies have shown that the arm movement of patients
with neurological injury is often slow. In this paper, the speed of arm movements in
healthy subjects is evaluated in order to validate the efficacy of using a Kinect camera
for automated analysis. The consideration of arm movement appears trivial at first
glance, but in reality it is a very complex neural and biomechanical process that can
potentially be used for detecting neurological disorders.
Methods: We recorded handmovements using a Kinect camera from 27 healthy
subjects (21 males) with a mean age of 29 years undergoing three different arbitrary
arm movement speeds: fast, medium, and slow.
Results: Our developed algorithm is able to classify the three arbitrary speed classes
with an overall error of 5.43% for interclass speed classification and 0.49% for intraclass
classification.
Conclusions: This is the first step toward laying the foundation for future studies that
investigate abnormality in arm movement via use of a Kinect camera.
Keywords: Hand speed analysis, Kinect, Physiological movement
