Overview
Brief Summary
Investigators wish to evaluate the effects of adding VTF to upper limb prostheses on functional outcome measures of upper limb prosthetic users.
Detailed Description
Investigators will perform three experiments: 1. Investigators will add vibrotactile feedback to prosthetic users during the execution of a standardized functional test and performance of simple grasping tasks, with a disruption to the normal visual feedback, and examine whether their performance and arm kinematics are improved with tactile feedback; 2. Investigators will examine the effects of adding the feedback to a prosthesis on the performance and visual attention during a dual task assignment in prosthetic users, and 3. Investigators will provide prosthetic users with the feedback, to use it at their natural surroundings for a week, and study the reported activity and satisfaction levels.
