A Novel Wrist Device for Characterizing the Components of Proprioceptive Acuity.

Proprioception is important in human motor control but can be impaired by neurological disease. Unfortunately, our understanding of proprioceptive deficit is very limited, especially for important joints such as the wrist. To address this gap, we have constructed a robotic testbed designed to measure different aspects of proprioceptive acuity at the human wrist during pronation/supination.
