Clinical effectiveness of combined virtual reality and robot assisted fine hand motion rehabilitation in subacute stroke patients.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robot-assisted therapy is regarded as an effective and reliable method for the delivery of highly repetitive rehabilitation training in restoring motor skills after a stroke. This study focuses on the rehabilitation of fine hand motion skills due to ...

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...

Comparison of kinematic and EMG parameters between unassisted, fixed- and adaptive-stiffness robotic-assisted ankle movements in post-stroke subjects.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
In this paper, we present an assist-as-needed scheme that effectively adapted the assistance provided by an ankle rehabilitation robot according to patient's participation and performance during therapeutic movements. We performed an error-based esti...

Kinematic effects of inertia and friction added by a robotic knee exoskeleton after prolonged walking.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
The capabilities of robotic gait assistive devices are ever increasing; however, their adoption outside of the lab is still limited. A critical barrier for the functionality of these devices are the still unknown mechanical properties of the human le...

Automated stand-up and sit-down detection for robot-assisted body-weight support training with the FLOAT.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Patients with impaired walking function are often dependent on assistive devices to retrain gait and regain independence in life. To provide adequate support, gait rehabilitation devices have to be manually set to the correct support mode or have to ...

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...

Lokomat therapy in Colombia: Current state and cognitive aspects.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Neurological disorders frequently affect walking function which is one of the most fundamental skills to improve quality of life and autonomy, and Lokomat has been a key piece for gait's rehabilitation. In this study, a diagnosis about the developmen...

Effects of partial body-weight support and functional electrical stimulation on gait characteristics during treadmill locomotion: Pros and cons of saddle-seat-type body-weight support.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
Robotic therapy for rehabilitation of the lower extremity is currently in its early stage of development. Aiming at exploring an efficacious intervention for gait rehabilitation, we investigate the characteristics of an end-effector gait-training dev...

Preliminary assessment of a lower-limb exoskeleton controller for guiding leg movement in overground walking.

IEEE ... International Conference on Rehabilitation Robotics : [proceedings]
This paper describes the design, implementation, and preliminary validation of a controller for a powered lower-limb exoskeleton that reshapes a user's leg movement during over-ground walking. The intended application of the controller is to facilita...

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...
