Robotic Hand-Assisted Training for Spinal Cord Injury Driven by Myoelectric Pattern Recognition: A Case Report.

American journal of physical medicine & rehabilitation
A 51-year-old man with an incomplete C6 spinal cord injury sustained 26 yrs ago attended twenty 2-hr visits over 10 wks for robot-assisted hand training driven by myoelectric pattern recognition. In each visit, his right hand was assisted to perform ...

Repeatability of grasp recognition for robotic hand prosthesis control based on sEMG data.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Control methods based on sEMG obtained promising results for hand prosthetics. Control system robustness is still often inadequate and does not allow the amputees to perform a large number of movements useful for everyday life. Only few studies analy...

Megane Pro: Myo-electricity, visual and gaze tracking data acquisitions to improve hand prosthetics.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
During the past 60 years scientific research proposed many techniques to control robotic hand prostheses with surface electromyography (sEMG). Few of them have been implemented in commercial systems also due to limited robustness that may be improved...

"Wink to grasp" - comparing eye, voice & EMG gesture control of grasp with soft-robotic gloves.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
The ability of robotic rehabilitation devices to support paralysed end-users is ultimately limited by the degree to which human-machine-interaction is designed to be effective and efficient in translating user intention into robotic action. Specifica...

Application of support vector machines in detecting hand grasp gestures using a commercially off the shelf wireless myoelectric armband.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
The propose of this study was to assess the feasibility of using support vector machines in analysing myoelectric signals acquired using an off the shelf device, the Myo armband from Thalmic Lab, when performing hand grasp gestures. Participants (n =...

Improved grasp function with transcranial direct current stimulation in chronic spinal cord injury.

NeuroRehabilitation
BACKGROUND: Recovering hand function has important implications for improving independence of patients with tetraplegia after traumatic spinal cord injury (SCI). Transcranial direct current stimulation (tDCS) is a noninvasive neuromodulation techniqu...

Combining a hybrid robotic system with a bain-machine interface for the rehabilitation of reaching movements: A case study with a stroke patient.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Reaching and grasping are two of the most affected functions after stroke. Hybrid rehabilitation systems combining Functional Electrical Stimulation with Robotic devices have been proposed in the literature to improve rehabilitation outcomes. In this...

Robot-assisted microsurgical forceps with haptic feedback for transoral laser microsurgery.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
In this paper, a novel, motorized, multi-degrees-of-freedom (DoF), microsurgical forceps tool is presented, which is based on a master-slave teleoperation architecture. The slave device is a 7-DoF manipulator with: (i) 6-DoF positioning and orientati...

Design and development of a sensorized cylindrical object for grasping assessment.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Aim of this work is to design and develop an instrumented cylindrical object equipped with force sensors, which is able to assess grasping performance of both human and robotic hands. The object is made of two concentric shells between which sixteen ...

An effective 3-fingered augmenting exoskeleton for the human hand.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Every year, thousands of Americans suffer from pathological and traumatic events that result in loss of dexterity and strength of the hand. Although many supportive devices have been designed to restore functional hand movement, most are very complex...
