Transverse forces versus modified ashworth scale for upper limb flexion/extension in para-sagittal plane.
IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Jul 1, 2017
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]
Jul 1, 2017
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]
Jul 1, 2017
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]
Jul 1, 2017
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]
Jul 1, 2017
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...
Gait assessment system based on novel gait variability measures.
IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Jul 1, 2017
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]
Jul 1, 2017
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...
Kinematic effects of inertia and friction added by a robotic knee exoskeleton after prolonged walking.
IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Jul 1, 2017
The capabilities of robotic gait assistive devices are ever increasing; however, their adoption outside of the lab is still limited. A critical barrier for the functionality of these devices are the still unknown mechanical properties of the human le...
Automated stand-up and sit-down detection for robot-assisted body-weight support training with the FLOAT.
IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Jul 1, 2017
Patients with impaired walking function are often dependent on assistive devices to retrain gait and regain independence in life. To provide adequate support, gait rehabilitation devices have to be manually set to the correct support mode or have to ...
Towards human-knee orthosis interaction based on adaptive impedance control through stiffness adjustment.
IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Jul 1, 2017
Rehabilitation interventions involving powered, wearable lower limb orthoses that can provide high-challenging locomotor tasks for repetitive training sessions, mainly when assist-as-needed strategies, such as adaptive impedance control, are designed...
