Summary

This research project is a study designed to address both motor and cognitive changes after stroke. Treatment for SN is elusive however there is support for prism adaptation treatment (PAT). Therapists need to know more about the effects of this treatment and if it is feasible in a group of stroke survivors with multiple lesions because these are the patients they are treating in the clinical setting. Also, it has not been investigated that using PAT to remediate SN will then as a result increase spontaneous UE movement of the weak limb.

BEHAVIORAL

Prism Adaptation

PAT uses wedged prism lenses to displace the entire visual field horizontally to the left or right (depending on the orientation of the base of the prism). The left-base prism lenses (thicker on the left) shift the entire visual field to the right. The result is a curving reaching trajectory, aiming toward the image location (right to the actual location) and then corrected toward the actual location. After several reaching movement, the coordinates of motor and visual systems are aligned, which in other words, is that the motor output adapts to the visual input, and thus the reaching trajectory is straight ahead to the object. This visually-guided goal-oriented movement is essential in PAT.
