Exoskeleton-assisted Training to Accelerate Walking Recovery Early After Stroke: the TARGET Phase II Study

In the experimental groups, participants are provided with 1-hour sessions of gait training with robot assistance, 4 times per week for 4 weeks. Assistance is provided by the Ekso GT (Ekso Bionics, Richmond, CA, USA), an exoskeleton consisting of fitted metal braces that supports the legs, feet, and trunk of the patient. Powered motors drive knee and hip joints in the sagittal plane to assist during standing up and walking over level surfaces. Steps are initiated if an active weight-shift towards the stance leg is performed by the patient. The provided assistance in stance and swing is adaptable to the patient's ability and can be adjusted for each leg separately.
