Abstract
This study presents subject specific lower limb joint angular kinematic and dynamic analysis at time and frequency domain as well as joint mechanical work, power and dynamic stiffness assessment during normal gait, stiff knee gait and slow running for indicative range operation of personalized active gait aid device. Gait aid devices present increasing interest for the generalization of gait rehabilitation, as an answer to the growth demand of population with gait rehabilitation need, as well as the insufficient health care personnel. Nevertheless, the large costs and standardized equipment leave out many patients without gait rehabilitation, with the need for low cost, personalized gait rehabilitation equipment, based on subject-specific analysis. In vivo and noninvasive case study was assessed of a healthy male subject 70 kg mass and 1.86 m height on human gait lab. Reflective adhesive marks were applied at skin surface of lower limb selected anatomical points and images captured with eight 100 Hz camera Qualisys along with ground reaction forces and force moments acquired at 2000 Hz with two AMTI force plates during foot contact with the ground on normal gait (NG) at comfortable auto-selected velocity, stiff knee gait (SKG) with lower knee flexion and slow running (SR) at minimum run velocity on stiff knee condition. Inverse kinematics and dynamics were performed using AnyGait with TLEM model and lower limb joint angular signal analyzed. Indicative range operation from lower limb joint mechanical assessment were obtained at complementary domain for subject specific gait aid device selection and parametrization.

Abstract
The amputation is a millennial surgical intervention which occurs mainly due to accidents and wars. Actually, considering the greater of people's longevity, there was an increase in the incidence of amputations, especially because of pathologies inherent to age, modern life's habits and urban violence. As the amputation is millennial, the artifices used by the amputated people to gait adaption also are. Today there are many transfemoral prosthesis models and, thinking about that, this research has the objective of compare two prosthesis models, a mechanical (3R15, provided by the Unified Health System-SUS) and a microprocessed (C-Leg). Therefore, was performed a search for volunteers which has been using a mechanical prosthesis for at least 2 years produced by the Associacao de Assistencia a Crianca Deficiente of Pernambuco (AACD-PE). After an initial screening of volunteers, mobility and functionality tests were realized for evaluation of kinematic performance. The tests were realized in linear tracks and tracks with obstacles, based on Ottobock (R) test protocol. On average, the velocity in linear and square tracks improved of 33.33% and 36.75%, respectively, there was a decrease in the time spent in the obstacle test of 35.96% and an increase in the distance in the slop test of 21, 98%. Based on this and in the reduced number of volunteers, it is concluded, in this first moment, that the C-Leg microprocessed prosthesis is kinetically better than the mechanical prosthesis 3R15, allowing a greater quality of life for the user, but it is necessary increase the number of volunteers to have more robust results.

Abstract
Population aging is a global reality, which can be characterized by morphological, psychological and functional changes. With the limitations resulting from the aging state, changes can occur in the performance of activities of daily living, such as decreased muscle strength, reduced bone mass, loss of flexibility and decreased capacity of the sensory system. Physiotherapy actively assists in the health promotion and prevention process, reducing the effects of the aging and improving the life quality. This paper has the objective of develop a movement monitoring device to assist in the rehabilitation of elderly people. The accelerometers or motion sensors, store data for long periods of time, providing information about the movement activities of the subjects over a desired period. These sensors are a useful tool in the assessment of physical activity. Through the data of accelerometer, it is possible to evaluate all type of physical activities. This is a pilot study composed by three steps: development, validation and application of the instrument. For the application and validation of this study, it was used a protocol of exercises, in order to capture the variations of the X, Y and Z axes of the accelerometers in each exercise. In the study, it was possible to identify the movements during the performance of the proposed protocol. Through he accelerometers position and the varying of his axes, it was possible to classify the exercises according to the number of repetitions and the time spent performing the exercise. In addition, it was possible to monitor remotely in real time by a physiotherapist. It is concluded that this device can assist in the management of elderly patients, assisting the health professional during the rehabilitation process.

Abstract
The human gait shows the single efficiency and functionality and can be considered the most complex functional activity of the human being. Foot drop can be defined as a significant weakness in the dorsal flexion of the foot. The functional electrical orthosis (FEO) are devices that use electrical stimulation to promote functional movements. Besides the FEO promotes the improvement of muscular tropism, this mechanism can be a source of relearning, because all events are interpreted by the body as his owns. This research sought to analyze the impact of the electrostimulation through the Walkaide (R) system in the angular movement of individuals with foot drop. The data were collected from seven patients and the focus of the evaluation of this research was the subtalar joint angle. After analyze the results, it could be seen that the Walkaide (R) promoted a significant gait improvement, meanly about the compensatory movements.
