Abstract
AIMS: The aim of this study was to investigate the effects of different frequencies of transcutaneous electrical nerve stimulation (TENS) regarding to accommodation and pleasantness of the different forms of application. METHODS: The sample consisted of 20 subjects randomly divided into 3 groups, in which they were submitted to 3 different frequencies of TENS: 7 Hz, 100Hz, 255Hz, pulse duration of 250 µs, for 20 minutes once a week over three weeks. The volunteers were instructed to indicate the first and subsequent accommodation moments. At the end of the period of data collection, subjects were asked about which frequency they thought most enjoyable. RESULTS: For the threshold of adaptation, considering all frequencies analyzed, it was found that there was no significant difference (p> 0.05), a fact that was also repeated for the number of adaptations in 20 minutes (p> 0.05). With regard to pleasantness, 11 subjects indicated the frequency of 7 Hz as the most enjoyable. CONCLUSIONS: There was no significant difference in threshold for adaptation and the number of adaptations between the frequencies used. The frequency of 7 Hz was identified as the most enjoyable then the frequency of 100 Hz.

Danilo de Oliveira Silva[1], Amanda Schenatto Ferreira[2], Ana Valéria Gonçalves[2], Marina Dalla Costa[2], Marina Zilio[2], Andersom Ricardo Fréz[3], Gladson Ricardo Flor Bertolini[4]. Objetivos: Investigar os efeitos de diferentes frequências da estimulação elétrica nervosa transcutânea (TENS - transcutaneous electrical nerve stimulation), em relação à acomodação e agradabilidade nas diversas formas de aplicação. Métodos: A amostra foi composta por 20 indivíduos, divididos aleatoriamente em três grupos, que foram submetidos à TENS, com três frequências diferentes: 7 Hz, 100 Hz e 255 Hz, com duração de pulso de 250 μs, por 20 minutos, uma vez por semana no período de três semanas. Resultados: Para o limiar de acomodação, considerando todas as frequências analisadas, verificou-se que não houve diferença significativa (p>0,05), fato que também se repetiu para o número de acomodações em 20 minutos (p>0,05). 11 indivíduos indicaram a frequência de 7 Hz como a mais agradável. Conclusões: Não houve diferença significativa no limiar de acomodação e no número de acomodações entre as frequências utilizadas. DESCRITORES: ESTIMULAÇÃO ELÉTRICA NERVOSA TRANSCUTÂNEA; PERCEPÇÃO DO TATO; MODALIDADES DE FISIOTERAPIA
