Prosthetic Limb Movement Feedback for Upper and Lower Extremity Amputees
To assess the functional characteristics and utility of upper and lower limb prosthetic devices (advanced bionic and current clinical standard-of-care) that incorporate physiologically relevant touch and/or movement feedback.
Arms and Interventions
|Experimental: Amputee and Able Bodied Subjects
Map the locations in the skin or deeper muscle where limb movement perceptions occur. Use tactors (small robots providing touch and vibration) to mechanically provide sensation to the residual muscles in amputees and the intact muscles in able-bodied. The functional experiments will occur concurrently with development and application of new prosthetic socket designs to incorporate control and feedback.
The tactor is a small robot providing touch and vibration.
Primary Outcome Measures
- Skin or tendon location [36 months]
Locations in the skin or muscle of the residual where percepts of touch or movement occur.
Secondary Outcome Measures
- Sorting Task [36 months]
Performance on a sorting task with and without tactor feedback.
- Sense of Agency Questionnaire [36 months]
Agreement with statements of agency and ownership related to perceptions of limb movement including unstructured self-reports.
Inclusion criteria are adults (18 years or over) with major limb amputation (at or above wrist or ankle).
Exclusion criteria are any skin or pain conditions that would preclude ability to withstand pressures on their limb or to wear a prosthetic socket, or cognitive barriers precluding providing informed consent.
