Motor Control

The motor control laboratory houses equipment capable of capturing local body movements (e.g., reaching) in 3-D with real-time tracking and visualization. 

Ascension trakSTAR magnetic motion analysis system

The electromagnetic motion analysis system is comprised of a mid-range wired transmitter and 8 wired sensors (Model 800: 8 mm wide). The system provides both position and rotation measurements with a total of 6 degrees of freedom. The system incorporates the pulsed DC magnetic technology which is 5 times less susceptible to distortion caused by nearby metal than AC technology. For upper extremity kinematics (as the main focus of the laboratory), one can examine shoulder proprioception, scapula kinematics, and end-point reaching accuracy for subjects with various pathologies (e.g., anterior shoulder instability).
