ABSTRACT
The model of brace developed consists of a neoprene kneepad that has an inflatable cuff positioned over the popliteal region of the knee. It provides stimuli on joint structures as well as a better biomechanical alignment during the stance phase of the gait. The aim of this study was to quantify the changes and adaptations induced by gait training with the use of orthotic device in hemiparetic patients. A quasi-experimental before-after study was held with twelve adult patients with hemiparesis due to cerebrovascular accident. The peaks of plantar pressure were the markers used to compare the three moments of the study: the baseline, when they were using the brace, and post-gait training. After the sessions of gait retraining with the orthosis, the redistribution of plantar pressures showed increased symmetry during the stance phase, mainly by reducing the pressure on the paretic forefoot (p=0.024) and by the increase in the rearfoot in the paretic side (p=0.010). In addition, these changes were associated with a decrease in pressure on all regions of the foot not affected, especially in the rearfoot after training. The results of the study suggest a change in the gait pattern of participants after using the brace. There has been greater symmetry of the values of the plantar pressure peaks when the affected side was compared with the nonaffected side. Training with the brace helps in the rehabilitation process, since it provides baropodometric values approaching the normal pattern of plantar distribution.
