Abstract

In the context of the diseases they leave neurological sequelae with the full or partial impairment of the functional activities of body essential parts, these functions may involve motor, sensory, behavioral, perceptual and language. The major concern turns to situations where it loses full or partial movement control, making the affected unable to perform daily living activities (ADL), as with the affected by stroke, stroke, which is a complex neurological deficiency symptoms which results in brain damage caused by changes in blood flow. In such cases, the motor deficits are characterized by hemiplegia (complete paralysis) or hemiparesis (partial or incomplete paralysis) on the opposite hemisphere to the site of injury occurred in the brain. The location and extent of the injury caused by stroke determine the neurological picture presented by the affected and range from mild to severe and can be temporary or permanent. If treated right away through rehabilitation therapy in the form of physical exercise (PE), in most cases the stroke of the frame can be reversed through physiotherapy action efficiency. However, to date not recorded an effective mechanical device that simulates physical training in the simultaneous movements of all injured parties arising from a stroke in coordinated exercise active or liability. In this context, the development of a device capable of performing effectively in physiotherapy action rehabilitation of the patient can be welcome. For this, we intend to study the conceptual design of a multi-axis chair to perform the EF of all structures affected by hemiplegia or hemiparesis (head, trunk, limbs). The conceptual design will address the study, design and simulation and computational validation using commercial CAD drawing programs.
