Representing high-dimensional data to intelligent prostheses and other wearable assistive robots: A first comparison of tile coding and selective Kanerva coding.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Prosthetic devices have advanced in their capabilities and in the number and type of sensors included in their design. As the space of sensorimotor data available to a conventional or machine learning prosthetic control system increases in dimensiona...

Quantitative measures with WREX usage.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper presents the results of two surveys conducted with users of a functional upper extremity orthosis called the Wilmington Robotic EXoskeleton (WREX). The WREX is a passive anti-gravity arm orthosis that allows people with neuromuscular disab...

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...

Intuitive adaptive orientation control of assistive robots for people living with upper limb disabilities.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic assistive devices enhance the autonomy of individuals living with physical disabilities in their day-to-day life. Although the first priority for such devices is safety, they must also be intuitive and efficient from an engineering point of v...

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...

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...

Rehabilitation for hemiplegia using an upper limb training system based on a force direction.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Hemiplegia patients have complete paralysis of half their body, and encounter many challenges in living an independent life. Rehabilitation of the lower body is more important than that of the upper body for independent living; thus, recovering upper...

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...
