Human Machine Interface System With the H2 Lower Limb Exoskeleton for Rehabilitation
University of Houston
Summary
This research study will investigate the use of smart lower limb robotic exoskeleton (developed by the CSIC, Spain) in rehabilitation after stroke. It will compare robotic-assisted rehabilitation with supervised motor practice. Additionally, it will also examine the use of noninvasive scalp electroencephalography (EEG) to learn specific brain wave patterns associated with learning to walk on the powered lower limb exoskeleton. The findings will be used to understand human-robot interaction and to design smart orthotic devices that can be controlled by thought activity and assist those that have lost all or part of their walking abilities.
Description
Stroke is the leading cause of neurological disability in the United States and accounts for the poor physical health and the social dysfunction evident in survivors. Gait impairment is a large contributor to long-term disability and ambulatory function in daily living. Many patients, however, lose the ability to walk independently, and furthermore, a large proportion does not regain their normal walking speeds following a stroke. In this context, newer robotic-aided therapeutic tools such as "wearable" lower-limb robotic exoskeletons have been developed, which allow for the user to be augment…

Interventions
- BehavioralRobot-assisted training with the H2 lower limb powered exoskeleton
The H2 is a powered, robotic lower limb exoskeleton with actuated hips, knees and ankles. A custom control algorithm has been implemented in this device, which allows for provision of assistance to lower limb segments during movement, dependent on user needs.
- BehavioralSupervised motor practice
Supervised motor practice involves lower limb rehabilitation, primarily walking and other applicable lower limb exercises performed by participants under the guidance and supervision of a research physical therapist.
