Rehabilitation strategy for post-stroke recovery using an innovative elbow exoskeleton

Abstract

Intensive and adaptive rehabilitation therapy is beneficial for post-stroke recovery. Three modes of rehabilitation are generally performed at different stages after stroke: external force-based control in the acute stage, assistive force-based rehabilitation in the midway of recovery and resistive force-based rehabilitation in the last stage. To achieve the above requirements, an innovative elbow exoskeleton has been developed to incorporate the three modes of rehabilitation in a single structure. The structure of the exoskeleton has been designed in such a way that the whole working region is divided into three where each region can provide a different mode of rehabilitation. Recovery rate can be varied for individuals since it depends on various parameters. To evaluate the rate of recovery, three joint parameters have been identified: range of angular movement, angular velocity and joint torque. These parameters are incorporated into the framework of planning a novel rehabilitation strategy, which is discussed in this article along with the structural description of the designed exoskeleton.

Adaptive Admittance Control of an Upper Extremity Rehabilitation Robot With Neural-Network-Based Disturbance Observer

“…The control strategy applied in therapeutic robot is one of the most important factors influencing the effectiveness of robot-aided rehabilitation training [19], [20]. Clinical research results indicate that the repetitive training and taskoriented functional activities contribute to improving the overall coordination of affected limb and preventing muscle atrophy.…”

“…In addition, a significant group of such patients are elderly people (6–10 million Poles) with similar negative deterioration of upper limb function due to neurodegenerative changes in the aging process [ 1 ]. Three modes of rehabilitation are used at different stages after a stroke: In the acute phase: external force-based control; Middle phase of recovery: supportive force-based rehabilitation; and Last phase: resistance-based rehabilitation [ 2 ]. …”
