Clinical usefulness and validity of robotic measures of reaching movement in hemiparetic stroke patients.

Journal of neuroengineering and rehabilitation
BACKGROUND: Various robotic technologies have been developed recently for objective and quantitative assessment of movement. Among them, robotic measures derived from a reaching task in the KINARM Exoskeleton device are characterized by their potenti...

Human upper-limb force capacities evaluation with robotic models for ergonomic applications: effect of elbow flexion.

Computer methods in biomechanics and biomedical engineering
The aim of this study was to apply models derived from the robotics field to evaluate the human upper-limb force generation capacity. Four models were compared: the force ellipsoid (FE) and force polytope (FP) based on unit joint torques and the scal...

Robot-supported upper limb training in a virtual learning environment : a pilot randomized controlled trial in persons with MS.

Journal of neuroengineering and rehabilitation
BACKGROUND: Despite the functional impact of upper limb dysfunction in multiple sclerosis (MS), effects of intensive exercise programs and specifically robot-supported training have been rarely investigated in persons with advanced MS.

Combined Clinic-Home Approach for Upper Limb Robotic Therapy After Stroke: A Pilot Study.

Archives of physical medicine and rehabilitation
OBJECTIVE: To investigate the feasibility of a combined clinic-home intervention using a robotic elbow brace and, secondarily, to collect preliminary data on the efficacy of this clinic-home intervention.

Robotic and clinical evaluation of upper limb motor performance in patients with Friedreich's Ataxia: an observational study.

Journal of neuroengineering and rehabilitation
BACKGROUND: Friedreich's ataxia (FRDA) is the most common hereditary autosomal recessive form of ataxia. In this disease there is early manifestation of gait ataxia, and dysmetria of the arms and legs which causes impairment in daily activities that ...

Invited commentary on comparison of robotics, functional electrical stimulation, and motor learning methods for treatment of persistent upper extremity dysfunction after stroke: a randomized controlled trial.

Archives of physical medicine and rehabilitation
In this issue of Archives of Physical Medicine and Rehabilitation, Jessica McCabe and colleagues report findings from their methodologically sound, dose-matched clinical trial in 39 patients beyond 6 months poststroke. In this phase II trial, the eff...

Human Joint Angle Estimation with Inertial Sensors and Validation with A Robot Arm.

IEEE transactions on bio-medical engineering
Traditionally, human movement has been captured primarily by motion capture systems. These systems are costly, require fixed cameras in a controlled environment, and suffer from occlusion. Recently, the availability of low-cost wearable inertial sens...

A review of technological and clinical aspects of robot-aided rehabilitation of upper-extremity after stroke.

Disability and rehabilitation. Assistive technology
Cerebrovascular accident (CVA) or stroke is one of the leading causes of disability and loss of motor function. Millions of people around the world are effected by it each year. Stroke results in disabled arm function. Restoration of arm function is ...

Comparison of robotics, functional electrical stimulation, and motor learning methods for treatment of persistent upper extremity dysfunction after stroke: a randomized controlled trial.

Archives of physical medicine and rehabilitation
OBJECTIVE: To compare response to upper-limb treatment using robotics plus motor learning (ML) versus functional electrical stimulation (FES) plus ML versus ML alone, according to a measure of complex functional everyday tasks for chronic, severely i...
