Amputation; Traumatic, Hand Clinical Trial

Official title:
Sensor Glove and Non-Invasive Vibrotactile Feedback Insole to Improve Hand Prostheses Functions and Embodiment

Clinical Trial Summary

State-of-the-art myoelectric prostheses provide upper limb amputees with a remarkable variety of grip patterns but lack proper feedback from touch sensation. This restriction limits the controllability of multi-articulated robotic hands, resulting in the rejection of the device in many cases. Amputees have often reminiscing sensations in the stump, i.e. by touching certain regions, it feels as if no longer existing fingers were touched. These regions form a phantom map and show promising results for touch feedback. However, not every amputee has one and the socket of a prosthesis offers limited space for additional devices. Thus, the investigators developed a feedback display which is worn in the shoe instead of the prosthesis itself. The investigators want to assess the viability of vibrotactile feedback stimulus on the foot as a substitution for pressure on the fingers of an artificial hand in a clinical study. The efforts are based on the hypothesis that a hand prosthesis with tactile feedback has better performance in manipulating fragile and heavy objects, compared with a standard commercial hand prosthesis without tactile feedback.
