conceptual design of a gait rehabilitation robot
Authors
abstract
gait rehabilitation using body weight support on a treadmill is a recommended rehabilitation technique for neurological injuries, such as spinal cord injury. in this paper, a new robotic orthosis is presented for treadmill training. in the presented design the criteria such as low inertia of robot components, backdrivability, high safety and degrees of freedom based on human walking are considered. this robot is composed of a leg exoskeleton for leg control and a segment for pelvis control. in the exoskeleton two degrees of freedom are considered for the hip joint and one for the knee joint. also two degrees of freedom are considered for the pelvis joints. the inertia of moving components and the required force for the robot motion are measured to evaluate the robot backdrivability and transparency. further, a walking algorithm is implemented on the robot and is tested on a human subject. evaluation of the design showed that the robot is suitable for gait rehabilitation exercises.

Gait therapy is important to a person’s recovery following spinal cord or brain injury, stroke, lower extremity surgery, as well as with many chronic conditions (e.g., Parkinson’s disease or multiple sclerosis). Although some affordable equipment for adult gait rehabilitation exists, such equipment for adaptive gait rehabilitation across the spectrum of pediatric sizes is not commercially avail...
full textThe Design and Realization of a Gait Rehabilitation Training Robot with Body Supporting Mechanism
With the increasing number of people who have problems with their walking, a new type of gait rehabilitation training robot has been put forward and designed. In order to meet the requirements of the gait rehabilitation training, the whole mechanical structure and control system have been designed, and the model machine for gait rehabilitation training robot has been made. Using the human gait ...
full textReview: Robot Devices for Gait Rehabilitation
The main motivation of gait rehabilitation is to help a patient recovering from injury, illness or disease, to recover some locomotor abilities in order to promote as much independence as possible in activities of daily living tasks, and to assist the patient in compensating for deficits that cannot be treated medically. However, the amount of hands-on therapy that patients can receive is limit...
