ABSTRACT
The performance of intelligent prosthetic knee has an important effect on the realization of physiological gait of transfemoral amputees. A new type of single axis hydraulic damping knee prosthesis was designed based on the analysis of physiological gait. The training methods of the stance and swing phase were proposed. Knee prosthesis test was done through simulation and measurement device. The control target of peak flexion angle during swing of knee prosthesis is chosen to be 60-70°. When the damper valve closure was 0%, maximum swing-phase knee flexion angle of knee prosthesis were (86±2)°, (91±3)° and (97±3)° with the speed of 0.8 m/s, 1.2 m/s and 1.8 m/s, respectively. Once the valve closure was changed, maximum swing-phase knee flexion angle with different speeds could be adjusted between 60° and 70° and the required valve closure percentage were separately 25%, 40% and 70%. The damping adjustment law of intelligent knee prosthesis to achieve physiological gait was revealed.
ABSTRACT
O presente trabalho pretendeu comparar a ansiedade relatada através da Escala Analógica de Humor (EAH) no Teste da Simulação do Falar em Público em adolescentes surdos e ouvintes. Participaram do experimento quinze surdos que dominam o alfabeto digital e a Língua Brasileira de Sinais (LIBRAS) (grupo experimental) e quinze ouvintes (grupo controle) com idades entre 11 a 18 anos, pareados em relação a variáveis sócio-econômicas e sexo. Ambos os grupos foram submetidos individualmente ao teste da simulação do falar em público, no qual a escala analógica de humor foi aplicada nas fases de adaptação, pré-discurso, durante o discurso e pós-discurso. Os resultados obtidos em ambos os grupos indicam que para a população de adolescentes o teste não gerou a ansiedade tipicamente relatada em adultos e não houve diferença estatística significativa entre os grupos segundo tipo de linguagem usada.
The purpose of this study was to compare the anxiety reported by deaf and normal hearing teenagers on the Public Speaking Simulation Test through the Humor Analog Scale (HAS). Fifteen deaf teenagers expert on the digital alphabet and on the Brazilian Sign Language (Libras) and fifteen normal hearing (control group) with 11 to 18 years of age participated on the study. Social economic class and genre were similar in the two groups. Both groups were individually submitted to a Public Speaking Simulation Test, and evaluated by the Humor Analog Scale applied on the adaptation phase, pre-speech phase, during the speech phase and after the speech phase. For the teenager population the test did not cause anxiety, typically obtained with adults. There was no significant statistic difference between the two different language groups.
