Adaptive learning to speed-up control of prosthetic hands: A few things everybody should know.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Domain adaptation methods have been proposed to reduce the training efforts needed to control an upper-limb prosthesis by adapting well performing models from previous subjects to the new subject. These studies generally reported impressive reduction...

Novel neural interface electrode array for the peripheral nerve.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Peripheral neural interface (PNI) is becoming an essential technology in the field of robotic prosthesis due to its potential for providing bidirectional neural signal communication between the prosthetic arm and the brain. However, current PNIs inef...

Inverse estimation of multiple muscle activations based on linear logistic regression.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This study deals with a technology to estimate the muscle activity from the movement data using a statistical model. A linear regression (LR) model and artificial neural networks (ANN) have been known as statistical models for such use. Although ANN ...

Fully embedded myoelectric control for a wearable robotic hand orthosis.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
To prevent learned non-use of the affected hand in chronic stroke survivors, rehabilitative training should be continued after discharge from the hospital. Robotic hand orthoses are a promising approach for home rehabilitation. When combined with int...

Interaction force and motion estimators facilitating impedance control of the upper limb rehabilitation robot.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In order to enhance the performance of rehabilitation robots, it is imperative to know both force and motion caused by the interaction between user and robot. However, common direct measurement of both signals through force and motion sensors not onl...

Gait assessment system based on novel gait variability measures.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, a novel gait assessment system based on measures of gait variability reflected through the variability of shapes of gait cycles trajectories is proposed. The presented gait assessment system is based on SVM (support vector machine) cla...

Comparison of kinematic and EMG parameters between unassisted, fixed- and adaptive-stiffness robotic-assisted ankle movements in post-stroke subjects.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, we present an assist-as-needed scheme that effectively adapted the assistance provided by an ankle rehabilitation robot according to patient's participation and performance during therapeutic movements. We performed an error-based esti...

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...

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...
