Currently, lower limb robotic rehabilitation is widely developed, However, the devices used so far seem to not have a uniform criteria for their design, because, on the contrary, each developed mechanism is often presented as if it does not take into account the criteria used in previous designs. On the other hand, the diagnosis of lower limb from robotic devices has been little studied. This chapter presents a guide for the design of robotic devices in diagnosis of lower limbs, taking into account the mobility of the human leg and the techniques used by physiotherapists in the execution of exercises and the rehabilitation of rehabilitation and diagnosis tests, as well as the recommendations made by various authors, among other aspects. The proposed guide is illustrated through a case study based on a parallel robot RPU+3UPS able to make movements that are applied during the processes of rehabilitation and diagnosis. The proposal presents advantages over some existing devices such as its load capacity that can support, and also allows you to restrict the movement in directions required by the rehabilitation and the diagnosis movements.

In this research was implemented the use of an Arduino UNO R3 microcontroller to control the movements of a prototype robotic functional developed to perform rehabilitation exercises in the wrist joint; This device can be used to assist the physiatrist to rehabilitate the tendinitis, synovitis, rheumatoid arthritis and for pre-operative and post-operative therapy in this joint. During the design stage of the functional prototype, the methodology of the industrial design process was used from a concurrent engineering approach, through which anthropometric studies could be performed related to the dimensions and angles of movement of the wrist joint in the population Venezuelan from the information collected, the design proposal was elaborated, and the use of CAD programs defined the different forms, geometries and materials of the components of the rehabilitation device, which were later analyzed using the finite element method for the determination The tensional state of efforts and safety factors through the use of CAE programs. In addition, a software was developed for the acquisition, registration, reproduction and execution of the different movements produced during the rehabilitation therapy. Through the research developed, a device was designed that will help the rehabilitation of the wrist joint allowing the combination of dorsal-palmar flexion and ulnar-radial movements to recover the joint function of various pathologies presented in the Venezuelan population.
