Abstract(s)
Objetivo: investigar a influência do tempo de uso de smartphone na força muscular da cervical e de preensão manual (PM), assim como nas disfunções da articulação temporomandibular (DTM) de jovens adultos. Metodologia: Participaram no estudo 48 indivíduos (25 do sexo feminino; 23 do sexo masculino), nos quais foi avaliada a força dos músculos flexores, extensores, inclinadores cervicais e de preensão manual por dinamometria, e a presença/severidade de DTM através do Questionário Anamnésico de Fonseca. Após reporte do tempo médio de uso de smartphone nos últimos 7 dias, os participantes foram divididos em 2 grupos (tempo de uso superior e inferior). Resultados: Não se verificaram diferenças entre os grupos nas variáveis de força cervical ou de PM (p>0.05). Também não se verificou associação entre as categorias de DTM e o tempo de uso de smartphone (p=0.741). Conclusão: Os resultados obtidos sugerem que o tempo de uso de smartphone parece não influenciar a força muscular da cervical ou de PM, assim como parece não haver associação com a DTM.
Aim: to investigate the influence of smartphone usage time on cervical and handgrip (HG) strength, as well as in temporomandibular joint disorders (TMD) in young adults. Methodology: 48 individuals (25 females; 23 males) participated in the study, in which the strength of cervical flexors, extensors, inclinators, and handgrip was assessed by dynamometry, and the presence/severity of TMD through the Anamnestic Questionnaire of Fonseca. After reporting the average smartphone usage time in the last 7 days, participants were divided into 2 groups (higher and lower usage time). Results: There were no differences between the groups in the variables of cervical strength or HG (p>0.05). There was also no association between TMD categories and smartphone usage time (p=0.741). Conclusion: The obtained results suggest that smartphone usage time does not seem to influence cervical or HG strength, as well as it appears to have no association with TMD.
