Brief summary
Implication and evaluation of a non-invasive sensory feedback system in hand prostheses in everyday life.
Detailed description
A non invasive sensory feedback system in embedded in the prosthetic socket will be tested on forearm amputees in their everday life. Pretests and follow up will contain objective outcome assessments and semi-structured interviews.
Interventions
DEVICEsmartskin non-invasive sensory feedback
The sensory feedback system used was a simple non-invasive, non-electronic system based on air-mediated pressure. A silicone glove with bulbs (35 mm in length) volar in every fingertip was made and applied on a VariPlus Speed hand (OttoBock), size 7¾. The sensory feedback system was embedded in the prosthetic socket.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of Myoelectric Control - ACMC | 2 days | An observational assessment where you rate the subjects' capacity of myoelectric control in a bimanual activity. The scoring was made by an experienced external rater. |
| Task performance questionnaire | 2 days | 21 questions about sensory feedback from the prosthesis, agency, body ownership, performance in activity and phantom limb pain. Self-administered estimation on a 7 grade Likert-scale. |
| Pointing task | 2 days | A objective measurement of body ownership. The subject are asked to mark on a ruler, with the hand prosthesis hidden, where they estimate the location of the prosthetic index finger. |
