Robot-Assisted Training of Arm and Hand Movement Shows Functional Improvements for Incomplete Cervical Spinal Cord Injury.

American journal of physical medicine & rehabilitation
OBJECTIVE: The aim of the study was to demonstrate the feasibility, tolerability, and effectiveness of robotic-assisted arm training in incomplete chronic tetraplegia.

Variable Thumb Moment Arm Modeling and Thumb-Tip Force Production of a Human-Like Robotic Hand.

Journal of biomechanical engineering
The anatomically correct testbed (ACT) hand mechanically simulates the musculoskeletal structure of the fingers and thumb of the human hand. In this work, we analyze the muscle moment arms (MAs) and thumb-tip force vectors in the ACT thumb in order t...

MoBio: A 5 DOF trans-humeral robotic prosthesis.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, a 5 DOF trans-humeral robotic prosthesis: MoBio is proposed. MoBio includes 2 DOF at wrist which is rare in other trans-humeral prostheses. Through anthropometric features MoBio prosthetic arm can achieve elbow flexion/extension, forea...

Design of a wearable interface for lightweight robotic arm for people with mobility impairments.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Many common activities of daily living like open a door or fill a glass of water, which most of us take for granted, could be an insuperable problem for people who have limited mobility or impairments. For years the unique alternative to overcame thi...

Learning from demonstration: Teaching a myoelectric prosthesis with an intact limb via reinforcement learning.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Prosthetic arms should restore and extend the capabilities of someone with an amputation. They should move naturally and be able to perform elegant, coordinated movements that approximate those of a biological arm. Despite these objectives, the contr...

Robots testing robots: ALAN-Arm, a humanoid arm for the testing of robotic rehabilitation systems.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotics is increasing in popularity as a method of providing rich, personalized and cost-effective physiotherapy to individuals with some degree of upper limb paralysis, such as those who have suffered a stroke. These robotic rehabilitation systems ...

A research on the postural stability of a person wearing the lower limb exoskeletal robot by the HAT model.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper proposes a method of detecting the postural stability of a person wearing the lower limb exoskeletal robot with the HAT(Head-Arm-Trunk) model. Previous studies have shown that the human posture is stable when the CoM(Center of Mass) of the...

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 =...

Shoulder motion assistance using a single-joint Hybrid Assistive Limb robot: Evaluation of its safety and validity in healthy adults.

Journal of orthopaedic surgery (Hong Kong)
PURPOSES: To evaluate the feasibility of using the single-joint Hybrid Assistive Limb robot (HAL) to assist with shoulder flexion-extension in healthy adults, and to assess the capacity of the HAL to analyze the bioelectrical signals of muscle activi...
