NCT04228224

Brief Summary

This research will study the effects of a rehabilitation program assisted by a powered lower extremity exoskeleton in patients after stroke. It will compare clinical and biomechanical features of patients at baseline and after intervention. Additionally, it will also examine the use of a brain-computer-interface (BCI) to command movements on the powered lower limb exoskeleton. The findings will be used to improve understanding human-robot interaction, to improve the design of the robotic devices and to improve rehabilitation services.

Study Arms (2)

Robot-assisted Rehabilitation

EXPERIMENTAL

Participants will receive Robot-assisted training with a lower extremity powered exoskeleton (H3 Exoskeleton, Spain). Patients will perform lower limb exercises assisted by the device. Training involve 24 sessions, 2 sessions per week for 12 weeks, each lasting about 1 hour.

Device: Robot-assisted training with a lower extremity powered exoskeleton (H3 Exoskeleton, Spain)

Conventional Gait Rehabilitation

ACTIVE COMPARATOR

Participants in this group will perform conventional gait rehabilitation on a rehabilitation institution with assistance of a physical therapist. Training involve 24 sessions, 2 sessions per week, each session lasting about 1 hour.

Behavioral: Conventional gait rehabilitation

Interventions

The H3 is a powered lower extremity exoskeleton with actuated at hips, knees and ankles joints. A novel control software has been design and implemented in this device, which allows selective joint movement and recording of data from each rehabilitation session.

Robot-assisted Rehabilitation

Conventional gait rehabilitation consist in walking and other applicable lower limb exercises performed by participants with assistance of a physical therapist.
