ABSTRACT A limited number of clinical studies have examined the effect of poststroke rehabilitation with robotic devices on hemiparetic arm function. We systematically reviewed the literature to assess the effect of robot-aided therapy on stroke patients' upper-limb motor control and functional abilities. Eight clinical trials were identified and reviewed. For four of these studies, we also pooled short-term mean changes in Fugl-Meyer scores before and after robot-aided therapy. We found that robot-aided therapy of the proximal upper limb improves short- and long-term motor control of the paretic shoulder and elbow in subacute and chronic patients; however, we found no consistent influence on functional abilities. In addition, robot-aided therapy appears to improve motor control more than conventional therapy.

    ABSTRACT: To assist physically disabled people with impaired upper limb function, we have developed a new 7-DOF exoskeleton-type robot named Motion Assistive Robotic-Exoskeleton for Superior Extremity (ETS-MARSE) to ease daily upper limb movements and to provide effective rehabilitation therapy to the superior extremity. The ETS-MARSE comprises a shoulder motion support part, an elbow and forearm motion support part, and a wrist motion support part. It is designed to be worn on the lateral side of the upper limb in order to provide naturalistic movements of the shoulder (vertical and horizontal flexion/extension and internal/external rotation), elbow (flexion/extension), forearm (pronation/supination), and wrist joint (radial/ulnar deviation and flexion/extension). This paper focuses on the modeling, design, development, and control of the ETS-MARSE. Experiments were carried out with healthy male human subjects in whom trajectory tracking in the form of passive rehabilitation exercises (i.e., pre-programmed trajectories recommended by a therapist/clinician) were carried out. Experimental results show that the ETS-MARSE can efficiently perform passive rehabilitation therapy.

    ABSTRACT: Cerebrovascular accident (CVA) or stroke is one of the main causes of disability. It affects millions of people worldwide. One symptom of stroke is disabled arm function. Restoration of arm function is necessary to resuming activities of daily living (ADL). Along with traditional rehabilitation techniques, robot-aided therapy has emerged in recent years. Robot-aided arm therapy is more intensive, of longer duration and more repetitive. By using robots repetitive dull exercises can turn into a more challenging and motivating tasks such as games. Besides, robots can provide a quantitative measure of the rehabilitation progress. This paper introduces a new robot for shoulder rehabilitation. The shoulder rehabilitation system (S.R.S) has three degrees of freedom (DOFs) for three rotational degrees of freedom of the shoulder. It also allows the additional translational DOFs of the shoulder to avoid discomfort to the patient. A new open circular mechanism is proposed for the third joint. The mechanical structure is designed and optimized in Solidworks and it is based on the properties of upper limb of an adult person. The proposed control algorithm is inverse dynamics control which is intended to be used in passive rehabilitation. The proposed control can efficiently track the desired trajectory and reject constant bounded disturbance input to the system.

    ABSTRACT: The Social Assistive Robotics (SAR), is an emerging technology that uses social interactive robotic platforms to assist people with special needs. Fields of application include the care of elderly subjects, patients with dementia or Alzheimer's diseases, cognitive/motor disorders, treatment of post-stroke patients and education of children with disabilities including autism spectrum disorder. Exploring the recent alliance between the fields of robotic and psychology, the paper deals with various studies on the acceptability of the robotic instrument in different application contexts. This contribution is concluded with objectives and future trend of development in this young research area.
