Diabetes Mellitus is a chronic and systemic disease which causes serious complications in worldwide scale. Within the several complications, the diabetic symmetric distal polyneuropathy stands out, and usually progresses from a sensorial loss to a motor impairment, resulting many times in autonomic involvement. One of the consequences of the diabetic neuropathy is the alteration in the muscular trophism, mainly in the intrinsic muscles of the ankle-foot complex, which can lead to deformities, limitation of joint mobility and alterations in the muscles activities during locomotion. Many studies describe the neuropathic diabetic gait in level floor, however literature is still scarce in the description of the activities of daily living of these individuals. Going up and down stairs represent a more real demand of the activities of daily living, beyond being mechanically different of the level walking. These activities require the motor system the ability and capacity to win vertical force to displace the body through the space. Therefore, our proposal is to describe and to compare the electrical activities of the tibialis anterior, lateral gastrocnemius, peroneus longus and vastus lateralis during the stance phase of the going up and down stairs between neuropathic diabetic and non diabetic subjects. The groups will be formed by 30 adult volunteers of both genders, divided equally into two groups: the control group and the neuropathic diabetic group. The experimental protocol will have two stages: (1) initial evaluation for an investigation of aspects related to diabetes and the diabetic neuropathy, (2) kinematic and electromyographic assessment of lower limb during the motor skills of go up and down stairs. Considering the functionality and the independence of this population is important to investigate the motor strategies adopted by diabetic neuropatic patients on your daily activities, because these alterations will help to understand part of the mechanism that makes this population ulcerate their feet in circumstances of daily living. Such information will be extremely relevant for the orientation of these people, beyond assisting the rehabilitation conducts of patients with diabetic neuropathy.
