ARM MOVEMENT ANALYSIS VIA MARKER TRACKING WITH A SINGLE-CAMERA SYSTEM: VALIDATION WITH A MOTION ANALYSIS SYSTEM IN STROKE AND HEALTHY SUBJECTS

Optical motion capture systems have been widely adopted for limb movement analysis in stroke rehabilitation because of their real-time processing and high-accuracy features. However, these systems can be costly and not transportable due to multiple-camera requirement. This paper proposes a marker-tracking-based single-camera system, an alternative, portable and cheaper scheme to implement arm movement analysis.
