Evaluation of a Non-invasive Sensory Feedback System in Hand Prostheses in Everyday Life.

Implication and evaluation of a non-invasive sensory feedback system in hand prostheses in everyday life.

Study Overview

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: sensory feedback

A non-invasive air-mediated sensory feedback system embedded in the prosthesis socket.

Group description: Individuals with acquired forearm amputation.

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment of Myoelectric Control - ACMC
Time Frame: 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.
2 days
Task performance questionnaire
Time Frame: 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.
2 days
Pointing task
Time Frame: 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.
2 days
