Self-aligning exoskeleton hip joint: Kinematic design with five revolute, three prismatic and one ball joint.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Kinematic compatibility is of paramount importance in wearable robotic and exoskeleton design. Misalignments between exoskeletons and anatomical joints of the human body result in interaction forces which make wearing the exoskeleton uncomfortable an...

On the stiffness analysis of a cable driven leg exoskeleton.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic systems are being used for gait rehabilitation of patients with neurological disorder. These devices are externally powered to apply external forces on human limbs to assist the leg motion. Patients while walking with these devices adapt thei...

Cross-wire assist suit concept, for mobile and lightweight multiple degree of freedom hip assistance.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, we present our cross-wire assist concept, for assisting a single joint in multiple degrees of freedom. It is comprised of four motor driven Bowden cable actuators (wires) per assisted joint, with the wires crossed over each other at th...

Timing of intermittent torque control with wire-driven gait training robot lifting toe trajectory for trip avoidance.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Gait training robots are useful for changing gait patterns and decreasing risk of trip. Previous research has reported that decreasing duration of the assistance or guidance of the robot is beneficial for efficient gait training. Although robotic int...

Design and experimental evaluation of a lightweight, high-torque and compliant actuator for an active ankle foot orthosis.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
The human ankle joint plays a crucial role during walking. At the push-off phase the ankle plantarflexors generate the highest torque among the lower limb joints during this activity. The potential of the ankle plantarflexors is affected by numerous ...

Toward goal-oriented robotic gait training: The effect of gait speed and stride length on lower extremity joint torques.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robot-assisted gait training is becoming increasingly common to support recovery of walking function after neurological injury. How to formulate controllers capable of promoting desired features in gait, i.e. goals, is complicated by the limited unde...

Position and torque control via rehabilitation robot and functional electrical stimulation.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Two common rehabilitation therapies for individuals possessing neurological conditions are functional electrical stimulation (FES) and robotic assistance. This paper focuses on combining the two rehabilitation strategies for use on the biceps brachii...

Use of Robotic Manipulators to Study Diarthrodial Joint Function.

Journal of biomechanical engineering
Diarthrodial joint function is mediated by a complex interaction between bones, ligaments, capsules, articular cartilage, and muscles. To gain a better understanding of injury mechanisms and to improve surgical procedures, an improved understanding o...

Development of a Robotic Colonoscopic Manipulation System, Using Haptic Feedback Algorithm.

Yonsei medical journal
PURPOSE: Colonoscopy is one of the most effective diagnostic and therapeutic tools for colorectal diseases. We aim to propose a master-slave robotic colonoscopy that is controllable in remote site using conventional colonoscopy.

Robotic-assisted locomotor training enhances ankle performance in adults with incomplete spinal cord injury.

Journal of rehabilitation medicine
OBJECTIVE: Ankle joint control plays an important role in independent walking. This study investigated the effects of robotic-assisted locomotor training on impaired ankle joint control in individuals with chronic incomplete spinal cord injury.
