DESIGN OF A SYSTEM FOR UPPER-LIMB REHABILITATION BASED ON AN ELECTROMECHANICAL ORTHOSIS AND sEMG WIRELESS SENSORS

摘要

Nowadays, upper-limb injury or impairment represent a widespread problem, related to sport accidents or traumas, surgery operations, stroke and so on. The typical approach to the rehabilitation is one or more physiotherapy sessions, to restore muscular mass and strength. Despite this, over the years, several works proposed innovative solutions, including electromechanical orthoses, which work in relation to the muscular activity, measured by techniques such as superficial electromyography (sEMG). Yet, these systems are still far from commercialization because of their cost, complexity and difficulties in using. A currently unmet need regards the ability of the therapist to control and manage data through a remote interface, by exploiting some of the latest technological resources on the market (smartphones, tablets). The present works aims at designing an upper-limb rehabilitation system, based on an orthosis, sEMG wireless sensors and a dedicated software architecture to overcome these limitations. This will lead to an important change of perspective in physiotherapy procedures since data collection and correlation will produce innovative medical protocols, addressed to people affected by several types of injury or impairment.
