This study investigates the simple reaction time (SRT) and response time (RT) to a vibrotactile stimulus presented on two body locations at the lower extremity of the foot on different types of surface during walking. We determined RTs while walking on Concrete, Foam, Sand, and gravel surface. Also, for RT, we evaluated two vibrotactile stimulus (VS) locations on the lower extremity: the ankle (AL) and under the foot plantar (FP). A total of 21 young adult participants (n = 21), aged mean 24 ± 2.9 years, took part in a two-session experiment with two main conditions (at rest and while walking on four types of surface). The control session included 2016 repeated measures, with one-way and two-way ANOVA analyses. The findings have consistently revealed slowness of RT to VS, in particular on sand and gravel surface. In addition, we found that body location has a significant effect on RT in certain surfaces. These results showed that RTs increased with environment changes during the performance of dual tasks.

“…In contrast to both simple and recognition tests, in the choice tests, HRT is estimated from multiple stimuli and it is expected the reacting individual makes a choice from among multiple responses. Several systems were developed and reported to estimate the reaction time of drivers using virtual reality time [8], computer-based measurement of cognitive functioning [9] and wearable systems [10][11][12]. The latter ones usually incorporate motion sensors mounted on the reacting individual.…”

The design and implementation of a wearable system to estimate the human reaction time (HRT) to visual stimulus based on two identical wireless motion sensors are described. Each sensor incorporates a motion sensor (gyroscope), a processor and a transceiver operating at the industrial, scientific and medical frequency of 2.45 GHz. Relevant tests to estimate the HRT are performed in two different scenarios including simple and recognition tests for 90 pairs of measurements. The obtained results are compared with a computer-based system to determine the accuracy of the proposed system. The root mean square error, standard deviation error and mean error of the results are 2.88, 6.17 and 0.3 ms for simple test while for recognition test as low as 3.34, 7.83 and 0.35 ms, respectively. The outcomes of the HRT estimation tests confirm HRT can increase by 40–87% due to increased fatigue levels.

“…A realização de testes de avaliação cognitiva ao longo da vida diária oferece oportunidades para detectar precocemente alterações na eficiência cognitiva, pois permite a identificação dos primeiros sintomas de comprometimento cognitivo em grupos de risco, como os idosos, ou para reduzir o risco de sobrecarga cognitiva para os trabalhadores que realizam tarefas complexas como assistentes de voo 2 , sendo o TR um teste simples e sensível para a detecção de variação na eficiência cognitiva 1,6 .…”

Este estudo analisou a produção científica relacionada ao uso de softwares de tempo de reação (TR), identificando o mais utilizado e descrevendo a temática dos estudos que fizeram uso deste software, a partir de artigos publicados na base de dados ScienceDirect (de 2001 até 2013), por ser abrangente e cobrir as principais áreas de interesse no uso deste tipo de software. A partir das palavras "reaction time" e "computer ou software", identificou-se o software E-Prime ® como o mais utilizado, totalizando 11 artigos que foram selecionados para esta pesquisa. Os itens investigados foram: periódico, objetivo do estudo, amostra, área de aplicação ou especialidade, acessório utilizado para resposta, tipo de TR, descrição da tarefa e resultados. O periódico Appetite publicou dois artigos, as demais publicações ocorreram em periódicos distintos. Predominaram pesquisas com adultos saudáveis (n=5), com média de 57,6 participantes. Para registro da resposta, foi utilizado um acessório externo que acompanha o software. Quanto ao tema, foram identificados e apresentados resultados sobre análises da coordenação e planos motores (n=2), análises de transtornos relacionados ao uso de substâncias (n=2), transtornos da visão (n=1), análises no comportamento alimentar (n=2), o efeito da motivação sobre o desempenho no TR (n=1) e os transtornos da fala e da linguagem (n=2), além da avaliação dos distúrbios da atenção em Parkinsonianos (n=1). Os resultados demonstram a diversidade de aplicabilidade de estudos com tarefas de TR com o uso de apenas um software e a forte relação entre TR e medidas de saúde física e cognitiva.Palavras-chave: tempo de reação; software; transtornos das habilidades motoras. ABSTRACTThe study analyzed scientific production related to the use of reaction time software (RT), to identify the most used and describe the main issues of studies that have made use of this software published from 2001 to 2013 in the ScienceDirect electronic database, since this database is comprehensive and covers the main areas of interest with the use of this software. From the words "reaction time" and "computer or software", the E-Prime ® software was identified as the most used, totaling 11 articles, which were selected for the study. The items investigated were: journal, objective, sample, application area or specialty, accessory used to reply, RT type, task description and results. The Appetite journal published two articles; the other articles were published in different journals, with predominance of research with healthy adults (n=5) with 57.6 participants on average. To record response in the data collection, it was used an external accessory accompanying the software. In relation to the topic, the results of articles on the analyses of coordination and motor plans (n=2), analyses of disorders related to the use of substance (n=2), vision disorders (n=1), analyses of feeding behavior (n=2), effect of motivation on performance in RT (n=1), speech and language disorders (n=2), and evaluation of attention disorders in Parkins...
