Rehabilitation robot is a type of assistant recovery equipment designed particularly for the sick people having difficulty in walking to get gait rehabilitation training, the research on joint flexibility is of great significance for the program making of walking gait control. The three closed-loops PID control method was proposed for the lower-limb rehabilitation robot MACCEPA (mechanically adjustable...
Rehabilitation Robot is a typical man-machine cooperation robot, which can drive the affected limbs to carry out various motor function recovery trainings within the same workspace of patients. To ensure the safety and comfort of the affected limbs during the training process, the system controller is designed based on the impedance control principle, thus the controller can make the robot has a certain...
Resistance exercise has been widely reported to have positive rehabilitation effects for patients with neuromuscular and orthopaedic disorders. This paper presents the design of a versatile rehabilitation device in the form of a rotation joint mounted on the adjustable arm support that provides a controlled passive resistance during strength training of hand muscles. The resistance is supplied by...
This paper presents the control architecture and preliminary experimental results of a high performance parallel robot used for ankle rehabilitation. The goal of this work was to design suitable control algorithms for diagnostic, training and rehabilitation of the ankle in presence of musculoskeletal injuries. A position control scheme is used for patient-passive exercises while an admittance control...
Numerous haptic devices have been developed for neurorehabilitation of upper extremities, but their wide-spread use has been largely impeded for reasons of complexity and cost. In this paper we describe a variable structure pantograph mechanism that produces a versatile rehabilitation robot for movement training of the shoulder, elbow, and wrist. The device has three operational modes: ARM, REACH...
A novel design of a hand functions task training robotic system was developed for the stroke rehabilitation. It detects the intention of hand opening or hand closing from the stroke person using the electromyography (EMG) signals measured from the hemiplegic side. This training system consists of an embedded controller and a robotic hand module. Each hand robot has 5 individual finger assemblies capable...
In this article the design of a new upper limb rehabilitation system will be presented. A lightweight, modular, and portable system is achieved by the combination of electromyographic (EMG) control, functional electrical stimulation (FES), and the use of miniaturized flexible fluidic actuators (FFA) integrated in an elbow orthosis. First, the state of the art of upper limb rehabilitation devices will...
Rehabilitation for upper limbs is important for the elderly people, the stroked patients and so on. In recent years, the needs for rehabilitation support systems are increasing, which use robot technology, virtual reality technology and neuroscience. In this paper we present about a development of evaluation system of the motor function for upper limbs using 3-D rehabilitation Robot ldquoEMULrdquo...
Restoring hand functions may greatly improve the post-stroke life quality. In this work, we developed a new interactive rehabilitation robot for hand function training after stroke. The robotic system can provide three modes of training: (1) continuous passive motion; (2) electromyography (EMG)-triggered motion; and (3) continuous EMG-driven motion to simulate the hand opening, grip and pinch tasks...
We have developed a robotic interface to train hand and finger function. HandCARE is a Cable-actuated rehabilitation system, in which each finger is attached to an instrumented cable loop allowing force control and a predominantly linear displacement. The device, whose designed is based on biomechanical measurements, can assist the subject in opening and closing movements and can be adapted to accommodate...
