Abstract:
1. A system for measuring an upper limb reaching capability of a user with an impaired limb, comprising: a horizontal surface including a default position; sensors for detecting limb choice, position information and elapsed time; a target display device displaying sequentially a plurality of spaced apart targets on the horizontal surface; and a controller operably connected to the target display device and the sensors, wherein the controller is configured to adaptively present the user with a series of targets to reach for based on the user's past performance, and to determine a measurement for the user's upper limb reaching capability based on a set of parameters comprising voluntary paretic limb use, non-use and limb function, and wherein the controller measures non-use of the limb by comparing the probability of reach in a forced use sequence to the probability of using the limb in a free choice sequence.
