A Systematic Analysis of Noninvasive Sensory Feedback Reconstruction Methods for Upper Limb Amputees

Abstract

The sensory feedback plays a vital role in hand grasping to prevent objects from sliding down, relieve the stump pain and muscle fatigue, and improve the sense of belonging to own body for the prosthetic users. However, reconstructing the sensory feedback of upper limb amputees remains a big challenge in robotic area. Following the recent achievements, this paper makes a systematic analysis of non-invasive sensory feedback reconstruction methods for upper limb amputees from a comprehensive perspective contained the whole process of sensory feedback reconstruction. Moreover, the sensory feedback physiology of the healthy and the latest progress in the assessment metrics of sensory feedback are surveyed. This paper can be used as a guideline for researchers to understand the gap and further improve the performance of sensory feedback reconstruction.
