Toward goal-oriented robotic gait training: The effect of gait speed and stride length on lower extremity joint torques.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robot-assisted gait training is becoming increasingly common to support recovery of walking function after neurological injury. How to formulate controllers capable of promoting desired features in gait, i.e. goals, is complicated by the limited unde...

Biomechanical effects of robot assisted walking on knee joint kinematics and muscle activation pattern.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Since manual rehabilitation therapy can be taxing for both the patient and the physiotherapist, a gait rehabilitation robot has been built to reduce the physical strain and increase the efficacy of the rehabilitation therapy. The prototype of the gai...

Research of the BWS system for lower extremity rehabilitation robot.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Body weight support (BWS) system is increasingly used in conjunction with treadmills to assist the patients with neurological impairments. Owing to lower limbs of the patients unable to bear the whole weight during the rehabilitation training, some w...

The effect of haptic interaction between balance assessment robot and pelvis on muscle activation of leg muscles.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Admittance control is considered as a promising paradigm in rehabilitation that provides us with means to establish well controlled and adjustable interaction and cooperation between rehabilitation devices and patients. Recently we developed balance ...

A novel robot-assisted training approach for improving gait symmetry after stroke.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Gait asymmetry as a consequence of hemiparesis is known as a serious long-term disability, where typical compensatory gait movements are used by stroke subjects in order to cope with their daily activities. This study presents a gait symmetry trainin...

MIT-Skywalker: On the use of a markerless system.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper describes our efforts to employ the Microsoft Kinect as a low cost vision control system for the MIT-Skywalker, a robotic gait rehabilitation device. The Kinect enables an alternative markerless solution to control the MIT-Skywalker and al...

How do strength and coordination recovery interact after stroke? A computational model for informing robotic training.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic devices can train strength, coordination, or a combination of both. If a robotic device focuses on coordination, what happens to strength recovery, and vice versa? Understanding this interaction could help optimize robotic training. We develo...

A multichannel-near-infrared-spectroscopy-triggered robotic hand rehabilitation system for stroke patients.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
There is a demand for a new neurorehabilitation modality with a brain-computer interface for stroke patients with insufficient or no remaining hand motor function. We previously developed a robotic hand rehabilitation system triggered by multichannel...

Improving robotic stroke rehabilitation by incorporating neural intent detection: Preliminary results from a clinical trial.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper presents the preliminary findings of a multi-year clinical study evaluating the effectiveness of adding a brain-machine interface (BMI) to the MAHI-Exo II, a robotic upper limb exoskeleton, for elbow flexion/extension rehabilitation in chr...

A novel method for muscle fatigue assessment during robot-based tracking tasks.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this work we propose a novel method based on sEMG signals, easy and fast to perform, administered with a robotic device to maximize repeatability and objectivity. Muscle fatigue, which is frequently experienced by healthy subjects, can be a highly...
