Unilateral Transradial Amputation
Conditions
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Orthotics and Prosthetics User Survey-Upper Extremity Functional Status | 2 weeks | A subjective questionnaire concerning the ability to perform daily tasks. The score ranges from 23 to 115. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Modified Box & Blocks test | 2 weeks | This test is aimed to assess unilateral gross manual dexterity. The test comprises of a two-compartment box and 16 cube blocks.The subject is instructed to transport the blocks as possible over the partition into the opposite compartment. The time in seconds is measured. |
| Time to complete dual tasking test | 2 weeks | The time needed to complete grasping tasks while playing a simple computer game with the other hand is measured in seconds. |
| Activity | 2 weeks | In order to record the actual use of the prosthesis in the natural environment of the subject, a wireless activity monitor that can be easily attached to the prosthesis will be used. The output measure of the activity monitor are activity counts. |
