Preliminary study of a robotic foot-ankle prosthesis with active alignment.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic prosthetic foot-ankle prostheses typically aim to replace the lost joint with revolute joints aimed at replicating normal joint biomechanics. In this paper, a previously developed robotic ankle prosthesis with active alignment is evaluated. I...

Quantitative assessment of motor functions post-stroke: Responsiveness of upper-extremity robotic measures and its task dependence.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Technology aided measures offer a sensitive, accurate and time-efflcient approach for the assessment of sensorimotor function after neurological impairment compared to standard clinical assessments. This preliminary study investigated the relationshi...

Robotic assessment of the contribution of motor commands to wrist position sense.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Assessing joint position sense for rehabilitation after neurological injury provides a prognostic factor in recovery and long-term functional outcomes. A common method for testing joint position sense involves the active replication of a joint config...

Towards quantifying dynamic human-human physical interactions for robot assisted stroke therapy.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Human-Robot Interaction is a prominent field of robotics today. Knowledge of human-human physical interaction can prove vital in creating dynamic physical interactions between human and robots. Most of the current work in studying this interaction ha...

EMU: A transparent 3D robotic manipulandum for upper-limb rehabilitation.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper introduces the EMU, a three-dimensional robotic manipulandum for rehabilitation of the upper extremity for patients with neurological injury. The device has been designed to be highly transparent, have a large workspace, and allow the use ...

Transverse forces versus modified ashworth scale for upper limb flexion/extension in para-sagittal plane.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Spasticity is a common impairment following an upper motor neuron lesion in conditions such as stroke and brain injury. A clinical issue is how to best quantify and measure spasticity. Recently, research has been performed to develop new methods of s...

Nonlinear disturbance observer based sliding mode control of a cable-driven rehabilitation robot.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper introduces a cable-driven robot for upper-limb rehabilitation. Kinematic and dynamic of this rehabilitation robot is analyzed. A sliding mode controller combined with a nonlinear disturbance observer is proposed to control this robot in th...

Utilization of kinematical redundancy of a rehabilitation robot to produce compliant motions under limitation on actuator performance.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper addresses the mechanical structure and control method of a redundant drive robot (RDR) to produce compliant motions, and show how the design parameters of the RDR can effect the produced motions and the mechanical and performance limitatio...

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...

Randomized, sham-controlled trial based on transcranial direct current stimulation and wrist robot-assisted integrated treatment on subacute stroke patients: Intermediate results.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
The main goal of this study is to analyse the effects of combined transcranial direct current stimulation (tDCS) and wrist robot-assisted therapy in subacute stroke patients. Twenty-four patients were included in this study and randomly assigned to t...
