Study of the Effectiveness of an Interactive Robot for the Rehabilitation of the Upper Limb in Acute Stroke Patients by Evaluating the 3 Fields of the ICF: a Prospective, Randomized, Controlled, Simple Blind Study

INTRODUCTION

The cerebral vascular accident affects two people per thousand each year (Duncan et al. 2005). This injury is the leading cause of permanent disability in our population. The brain damage is expressed by different neurological impairments and functional disabilities. These disabilities justify intensive and sustained multidisciplinary rehabilitation to reduce neurological impairments, to improve the activities and participation of patients, and, ultimately, their quality of life (Duncan et al., 2005).

Recently appeared in rehabilitation to stimulate maximum brain plasticity robotic devices meet the actual recommendations existing in stroke's rehabilitation (Langhorne et al., 2011). Indeed, the robots allow the execution of a large number of movements whose quality is controlled. A visual interface gives the patient a feedback of its movements, and offers exercises oriented functional tasks that have meaning for him and the possibly dive into a virtual reality. All these elements justify the clinical development of robots to assist the therapists (Pignolo et al. 2009).

The therapeutic efficacy of these robots for the rehabilitation of the upper limb was evaluated especially in chronic stroke patients (> 6 months after stroke) (Mehrholz et al., 2012). Unfortunately, few quality studies was conducted in these patients at the acute stage of rehabilitation, during which the potential of brain plasticity is the most important and the largest functional progress are observed (Stinear et al. 2012). In addition, few studies have evaluated the effect of these therapies robotic on the three fields of the ICF (Mehrholz et al., 2012). Many studies focus on impairments (e.g. muscle strength) without assessing the functional ability of the patient in activities of daily living.
