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 users 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.
