The scientific researches in the field of rehabilitation engineering are increasingly providing mechanisms in order to help people with disability to perform simple tasks of day-to-day. Several studies have been carried out highlighting the advantages of using muscle signal in order to control rehabilitation devices, such as experimental prostheses. This paper presents a study investigating the use...
A body-weight support locomotion training (BWSLT) device has been developed for the lower limb rehabilitation. In order to evaluate the effectiveness of the device, seven healthy subjects have participated the walking experiments. The experiments include the walking along a floor mat and the walking with the assistance of the device. On the other hand, experiments have been conducted on one spinal...
Robot-assisted rehabilitation has only recently begun to be applied to improvement of hand function after stroke. In a preliminary study, involving 4 post-stroke subjects, more than 2 years following the stroke, we have been able to show that 8 weeks of robot-assisted training leads to changes in patterns of arm and finger muscle activation. The patterns were quantified in terms of synchronous muscle...
Individuals who have upper limb movement problems include people with cerebral palsy (CP) and stroke victims. Both these conditions lead to difficulties in daily activities such as reaching, grasping etc. Virtual reality (VR), which could provide a repetitive multimodal task-oriented rehabilitation environment for patients to undertake self-training in safety, is considered to be a suitable tool for...
Quantitative evaluation for estimating motor function is a prerequisite for clinical application of rehabilitation robot. The current clinical evaluations, such as Fugl-Meyer assessment, still have some deficiency. The study provided an innovative evaluation method, which contrasted the physiological character of impaired limb with the contralateral upper limb of post stroke hemiplegic patients, and...
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...
This article describes a patient training evolution to achieve myoelectric control in the remnant limb. The methodology is divided in two main stages: (i) the training procedure, where the patient is submitted to a protocol for educating the muscles of the remnant limb, and (ii) myoelectric signal acquisition and analysis, in order to measure the patient evolution to reach different contraction levels...
This paper presents the design of an admittance-based assistive controller and preliminary experimental results for a high performance parallel robot used for ankle rehabilitation. The goal of this work was to design a suitable control algorithm for diagnosis, training and rehabilitation of the ankle in presence of musculoskeletal injuries. An admittance control technique is used to perform patient-active...
A functional electrical stimulation (FES)-robot system controlled by subjects' motor intention was developed in our previous study. The effectiveness of the FES-robot on wrist training was investigated in this work. Five hemiplegic subjects with chronic stroke were recruited for an FES-robot assisted wrist training with 20 sessions. After the training, motor improvements were found in the wrist and...
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...
Accidents happen and unfortunately people may loose part of their body members. Studies have shown that in this case, most individuals suffer physically and psychologically. For this reason, actions to restore the patient's freedom and mobility are imperative. Traditional solutions require ways to adapt the individual to prosthetic devices. This idea is also applied to patients who have congenital...
The hand motion function of Cerebral Palsy (CP) and stroke patients could be improved by task-oriented rehabilitation. Nowadays, there is a move in the development of the rehabilitation environment from the real world to virtual worlds. Patients could benefit from virtual reality (VR) based rehabilitation by multimodal and multiform feedback. However, it is recognised that such feedback might cause...
In order to improve the functional ability of hand through the identified functional activities of daily living (ADL) and rehabilitation training, we have considered the fundamental issues that constitute systematic, objective and quantitative assessment together with the development of a hand rehabilitation system. The targeted rehabilitation groups are those patients with motor weakness, such as...
Games-based biofeedback training uses augmented feedback signals to control the action of computer games. The NeuroGymreg system of games-based biofeedback has been used to improve the muscle activation and gait pattern of a patient with spinal cord injury. Training with this system also improved functional balance in a group of active older adults.
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...
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...
The effect of using robots to improve motor recovery has received increased attention, while the treatment effectiveness remains a topic of study. We compared the training effects by treatments on the wrist joint of chronic stroke patients with an electromyography (EMG)-driven robot (interactive group, n = 15) and a robot with continuous passive motion (passive group, n = 12) by a randomized controlled...
The Children's Rehabilitation Center Telethon of the State of Mexico (CRIT-EM) provides care to disabled children carriers of neural-muscle-skeletal diseases. The CRIT-EM's medical model includes the use of high technology as a tool for assessment and treatment. The objective of this work is to show how high technology is used in the rehabilitation process. The technologies included are the motion...
In this paper, a methodology for gait rehabilitation, combines over-ground walking, body weight support, pelvic control, and gait assistance are introduced and the integrated platform has been developed. This paper also discusses the gap of state-of-the-art research in gait rehabilitation. Systems like Lokomat and Kineassist were studied and discussed. Initial testing and EMG experiments have been...
The evaluation and teaching of motor skills in relation to patients are two important aspects of motor skill training. These two points or problems must be resolved in order to make such training effective. To address the issues simultaneously within a single system, this study proposes a cybernetic rehabilitation aid (CRA) under the concept of direct teaching using tactile feedback with an EMG-based...
