In recent years, several technological innovations have emerged to improve the rehabilitation of traumatic spinal cord injury (SCI). Among them, robotic orthosis, also known as human exoskeletons, are prominent devices for lower limb therapy. Since the early 2000s, numerous clinical studies have begun to investigate the efficacy of these devices, demonstrating the beneficial effects of exoskeletons regarding the prevention and deceleration of the progression of complications following spinal cord injury and subsequent immobilization. Previous works also deal with physiological, psycho-social and social effects, and presents possible risk factors following SCI. In this paper, the main results of the relevant international research is reviewed, the structure and operation of the first devices (ReWalkTM P6.0) in Hungary are presented, also, the main modalities of robotic assisted rehabilitation activity at international level are demonstrated. Based on the international results, the training protocol for a multicentre controlled clinical trial, involving the University of Pécs and the National Institute for Medical Rehabilitation is presented in this work. According to our hypothesis, high intensity exoskeleton-assisted complex rehabilitation induces positive changes in bone density, in the urogenital and gastrointestinal tract. Changes are quantified by objective urodynamic and defecative parameters. The difference in bone density is assessed with DEXA scan, and the effects on mental status are evaluated by questionnaires. The aim of this research is to promote a complementary therapeutic procedure based on validated results for SCI patients with paraplegia, also to establish recommendations for home use of the robotic exoskeletons, and to conceivably join to international scientific research projects.
