Abstract: The present invention relates to a low cost motion capture system for clinical utilizations, such as for upper-extremity (UE) motor control rehabilitation. As contemplated herein, the present invention records range of motion data and graphs rotation, flexion, and abduction motions of a targeted joint in real time. In certain embodiments, the hardware of the system may include a simple motion node attachment system, motion node labels, a user's manual, and anatomical diagrams to increase accuracy of motion node placement. In other embodiments, additional features include acceleration data collection and graphical display, rhythmic sound cues for assistance in motion emulation, audio cues for patients with visual impairments, hard copy reports of session results, real time range of motion displays, and a spatial visualization option.

Abstract: The present invention relates to a dual-purpose assessment and intervention tool that uses motion capture technology to measure fine motor control through the task of handwriting. The intervention portion of the tool contains various subsections designed to measure fine motor control, including tracing a maze and both tracing and copying a variety of characters. The assessment portion of the tool contains a standard set of exercises designed to provide an overall impression of fine motor control. The assessment portion of the tool generates a numerical score based on pixel-by-pixel accuracy and speed of writing.
