“…[6][7][8][9][10] This was adapted to include some further questions related to demographics, as well as the self-reported use of loupes with or without illumination, levels of fitness and exercise, the use of various strategies to help address the problem and the impact of pain on ability to perform dental procedures. Students were offered further support if this problem was having a significant impact on their overall health and quality of life.…”

P S and neck/upper extremity symptoms during computer work (Bergqvist et al, 1995;Faucett and Rempel, 1994;Karlqvist et al, 2002;Punnett and Bergqvist, 1997;Tittiranonda et al, 1999). Conclusions regarding cause-effect relationships cann be drawn from these studies, due to their cross-sectional design.…”

Among this population approximately 40% of the women and 25% of the men experienced symptoms in the neck and/or upper extremities at least once a week during the preceding 3 month. The overall aim of the studies underlying this thesis was to explore possible associations between working technique and perceived exertion, comfort, biomechanical and psychosocial strain as well as neck and upper extremity symptoms among computer users. Specific research questions addressed were a) Whether working technique was associated with muscle activity, wrist positions and forces applied to the computer mouse, respectively? b) Whether working technique was associated with psychological demands, emotional stress and perceived muscle tension, respectively? c) Whether there were associations between self-rated perceived comfort and observations of workplace layout and between self-rated perceived exertion and working postures. d) Whether working technique perceived exertion and comfort was associated with neck and upper extremity symptoms.The results showed that subjects classified as having a good working technique worked with less muscular load in the forearm (p=0.03) and in the trapezius muscle on the mouse operating side (p=0.02) compared to subjects classified as having a poor working technique. Subjects who reported high psychological demands and perceived muscular tension, respectively, used poorer working technique than subjects who did not perceive this conditions (demands, p=0.03, muscular tension, p=0.02). Moreover, the concordance between ratings of comfort and observations of workplace layout was reasonably good concerning the working chair and the keyboard and good regarding the computer screen and the input device. The concordance between ratings of perceived exertion and observations of working postures indicated good agreement for all measured body locations. This applies to the group that rated poor comfort and high exertion. Regarding the group that rated good comfort and low exertion ratings must be supplemented with observations. Furthermore, the results revealed that high perceived exertion and low comfort were related to an increased incidence of neck, and upper extremity symptoms, while poor working technique was not associated with such a risk. It is concluded that working technique is associated with both biomechanical and p...

“…Sua causa nem sempre é evidente e pode, inclusive, ser indefinida. Consideram-se crônicas as dores em que o sintoma ou conjunto de sintomas mantém-se além do tempo fisiológico de cicatrização de determinada lesão, ou, então, as dores que permanecem por mais de três meses continuamente [6][7][8] .…”

RESUMOIntrodução: A dor é uma experiência subjetiva, que pode resultar de características teciduais, mas que também abrange fatores de várias ordens, incluindo os emocionais, culturais e individuais. A dor crônica é persistente ou recorrente, por mais de 3 meses, de causa desconhecida e não está necessariamente associada a uma lesão no organismo. Os gastos associados a essa condição de saúde estimulam o sistema a investigar intervenções eficazes para o tratamento das dores em geral. O fenômeno da analgesia induzida pelo exercício é sobretudo observado em atletas e os mecanismos envolvidos ainda são desconhecidos, embora haja tendência a aceitar a ação do sistema opióide endógeno. Objetivo: Investigar o efeito de um programa de exercícios físicos sobre a dor crônica inespecífica. Método: A amostra foi constituída por 29 indivíduos que aderiram a um programa de exercícios domiciliares. Sendo aplicado o Questionário Internacional de Atividade Física (IPAQ) que permite estimar o tempo semanal gasto em atividades físicas de intensidade leve, moderada e vigorosa e a Escala Visual Analógica (EVA) que foi utilizada para avaliar a intensidade da dor. A análise estatística foi realizada de forma descritiva e inferencial. Conclusão: A aplicação de programas multidisciplinares, predominando a prescrição de exercícios aeróbicos, de fortalecimento e alongamentos, em um protocolo de exercícios domiciliares apresentou melhora efetiva no limiar de dor em paciente com dor crônica inespecífica.Palavras chave: dor crônica, exercício, medicina do esporte. ABSTRACT Introduction: Pain is a subjective experience, which can result from tissue characteristics, but which also includes factors of various types, such as emotional, cultural and individual factors. Chronic pain is defined as persistent or recurrent pain, lasting for more than 3 months, of unknown cause, and not necessarily associated with a bodily injury. The costs associated with this health condition have prompted the system to investigate effective interventions for the treatment of pain in general. The phenomenon of exercise-induced analgesia is mainly observed in athletes
