Online sparse Gaussian process based human motion intent learning for an electrically actuated lower extremity exoskeleton.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
The most important step for lower extremity exoskeleton is to infer human motion intent (HMI), which contributes to achieve human exoskeleton collaboration. Since the user is in the control loop, the relationship between human robot interaction (HRI)...

Gait assessment system based on novel gait variability measures.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, a novel gait assessment system based on measures of gait variability reflected through the variability of shapes of gait cycles trajectories is proposed. The presented gait assessment system is based on SVM (support vector machine) cla...

Towards human-knee orthosis interaction based on adaptive impedance control through stiffness adjustment.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Rehabilitation interventions involving powered, wearable lower limb orthoses that can provide high-challenging locomotor tasks for repetitive training sessions, mainly when assist-as-needed strategies, such as adaptive impedance control, are designed...

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...

Biomechanical effects of robot assisted walking on knee joint kinematics and muscle activation pattern.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Since manual rehabilitation therapy can be taxing for both the patient and the physiotherapist, a gait rehabilitation robot has been built to reduce the physical strain and increase the efficacy of the rehabilitation therapy. The prototype of the gai...

OBJECTIVE: To evaluate the security and efficiency of a surgical robotic assisted percutaneous screw fixation for the treatment of pelvic and acetabular fractures.

The features of Gait Exercise Assist Robot: Precise assist control and enriched feedback.

NeuroRehabilitation
BACKGROUND: In a patient with severe hemiplegia, the risk of the knee giving way is high during the early stage of gait exercise with an ankle-foot orthosis. However, use of a knee-ankle-foot orthosis has many problems such as large amount of assista...

Relationship between magnitude of applied torque in pre-swing phase and gait change for prevention of trip in elderly people.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
Elderly people are at risk of tripping because of their narrow range of articular motion. To avoid tripping, gait training that improves their range of articular motion would be beneficial. In this study we propose a gait-training robot that applies ...

A wearable robotic orthosis with a spring-assist actuator.

Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference
This paper introduces a wearable robotic orthosis with spring-assist actuators, which is designed to assist people who have difficulty in walking. The spring-assist actuator consists of an electrical motor and a spring, which are attached to a rotati...
