Robot rehabilitation devices are attracting significant research interest, aiming at developing viable solutions for increasing the patient’s quality of life and enhancing clinician’s therapies. This paper outlines the design and implementation of a low-cost robotic system that can assist finger motion rehabilitation by controlling and adapting bot...

This work presents a novel application of a system to assist therapies during upper limb rehabilitation. The design and kinematic analysis of a device proposed is presented. Two mechanisms are driven by only one motor develop circular, arc and linear paths in order to move the shoulder and elbow joints in rehabilitation therapies. The first mechani...

This document describes the method for identifying the trajectory of the index finger using image processing analysis, the analyzed trajectory corresponds to the flexion-extension movements performed by the fingertip naturally. As the trajectory identification method considers pixel units, the camera calibration process is performed using the Heikk...

Due to the growing demand for assistance in rehabilitation therapies for hand movements, a robotic system is proposed to mobilize the hand fingers in flexion and extension exercises. The robotic system is composed by four, type slider-crank, mechanisms that have the ability to fit the user fingers length from the index to the little finger, through...

Abstract This work presents a novel application of a four-bar mechanism to assist therapies during hand fingers rehabilitation. The system is a mechatronic device able to perform fingers flexoextension exercises and can be adapted to different hand sizes. Fingers flexoextension analysis is based on a kinematic finger model from index to little to d...
