The lower limbs have the locomotion function and body weight support. The articulation that composes it are organized by chains, allowing that ascending and or descending musculoskeletal adequations, from articular pathology in lower limbs, are installed, altering biomechanical patterns of the gait. Two frequent and chronic diseases that affects the world's population are characterized by diabetic peripheral neuropathy (DPN) and by osteoarthrosis (OA). The DPN's primary manifestation is the injured ankle and foot and in OA is more significant on the knee. Several studies showed that painful stimuli and sensibility alterations in intermediate and distal extremity promotes changes on the march pattern, as reduction of the weight over the rearfoot and redistribution and reorganization to other plantar regions, possibly because of the protective mechanism and after because of the muscular weakness. On nowadays literature, we can observed the identification of the kinematic variables among for planning and applying rehab interventions to help on the compromised march, localised on the compromised segments, most of the times not amplifying the visibility to more than two articulations. In conclusion, the importance and need to verify the characterization and kinematics and kinetics behavior, ascending and descending, of Distal articulations manifests (ankle) and intermediate (knee), in all inferior members during locomotion, it is impossible to isolate one segment when approaching the course of a disease or the final result of a rehabilitation. In this context, the need to verify the kinematics and kinetics of the three articular inferior members is observed, in pathologies that affect different articular levels. The identification of the behaviour of these variables can help on planning, therapeutic result and on the success of the rehabilitation. That being, this present study's main goal is to verify the kinematics and kinetics among the three articular complexes of the inferior members (hips, knees and ankles) during gait.
