Influência de um programa de exercícios específicos em estudantes de violino

Introdução: A elevada prevalência de problemas musculosqueléticos relacionados com a performance musical (PMRPM) em estudantes universitários de música, sobretudo violinistas, justifica uma abordagem preventiva junto destes, nomeadamente, através do exercício. Este deve ser específico e baseado nos padrões de movimento durante a performance musical do violinista. Objetivos: verificar a influência de um programa de exercícios específicos (PEE) nos sintomas relacionados com a prática musical, na incapacidade funcional e na autoperceção da performance física e musical, em estudantes universitários de violino. Métodos: estudo quase-experimental baseado num estudo piloto com 24 estudantes para pesquisa da sintomatologia, e 4 para análise cinemática e cinética do gesto técnico. No estudo principal participaram 22 violinistas divididos equitativamente, e por disponibilidade, entre grupo experimental (GE) e grupo de controlo (GC). O GE realizou o PEE bissemanalmente, durante 8 semanas. No momento inicial e após 8 semanas, os participantes preencheram: Questionário de Performance (incluiu Escala Visual Analógica), Disabilities of the Arm, Shoulder and Hand, Oswestry Disability Index versão 2.0, Pain Catastrophizing Scale e Escala de Borg Modificada. Resultados: do estudo piloto constatou-se que os sintomas mais frequentes, dor e fadiga, localizavam-se na cintura escapular, ombros e coluna lombar; os ombros aparentavam maior risco de PMRPM; era necessário aumentar a endurance dos mobilizadores dos membros superiores (principalmente deltóide) e relaxar os estabilizadores da coluna cervical (sobretudo trapézio superior). No final do PEE, o GE apresentou significativamente melhores pontuações do que o GC na percentagem de violinistas com “dor na coluna lombar esquerda” (p=0,007), frequência da dor (U=8,5; W=29,5; p=0,016), número de locais com sintomas (U=18; W=84; p=0,003) e amplificação (U=26; W=92; p=0,021). Conclusão: Um PEE pode produzir efeitos positivos na diminuição dos sintomas relacionados com a prática musical e incapacidade funcional, e na melhoria de alguns parâmetros da performance física autoreportada, em estudantes universitários de violino.

Cultural adaptation and psychometric properties of Brazilian Need for Recovery Scale

OBJECTIVE: To translate the Need for Recovery Scale (NFR) into Brazilian Portuguese and culturally adapt it and assess the stability, internal consistency and convergent validity of the Brazilian scale among industrial workers. METHODS: The translation process followed the guidelines for cultural adaptation of questionnaires including the steps of translation, synthesis, back translation, expert committee review, and pre-testing. The Brazilian Portuguese NFR, final version (Br-NFR) was assessed for stability (n=52) and internal consistency (n=192) and for convergent validity through simultaneous assessment with other instruments: the Borg Scale (n=59); the Chalder Fatigue Questionnaire (n=57) and 3 subscales of the SF-36 (n=56). RESULTS: Stability and internal consistency met the criterion for a reliable measure (ICC=0.80 and Cronbach's alpha =0.87, respectively). The convergent validity between Br-NFR and other instruments also showed good results: Borg Scale (r= 0.64); Chalder Questionnaire (r= 0.67); SF-36 subscales: vitality (r= -0.84), physical functioning (r= -0.54), and role-physical (r= -0.47). CONCLUSIONS: The Br-NFR proved to be a reliable instrument to evaluate work-related fatigue symptoms in industrial workers. Furthermore, it showed significant and good correlations with well-established instruments such as the Borg Scale, the Chalder Questionnaire and SF-36 vitality subscale, supporting the validity of the Br-NFR.

Sleep, stress and compensatory behaviors in Australian nurses and midwives

OBJECTIVE: To describe sleep, stress and compensatory behaviors in nurses and midwives. METHODS: The study included 41 midwives and 21 nurses working in Australian hospitals between 2005 and 2009. Participation was voluntary. All participants recorded on a daily basis their work and sleep hours, levels of stress and exhaustion, caffeine intake and use of sleep aids for a month (1,736 days, 1,002 work shifts). RESULTS: Participants reported moderate to high levels of stress and exhaustion on 20-40% of work days; experienced sleep disruption on more than 50% of work days; struggled to remain awake on 27% of work days; and suffered extreme drowsiness or experienced a near accident while travelling home on 9% of workdays. Age, perceived sleep duration and work hours were significant predictors of caffeine intake. About 60% of participants reported using sleep aids (about 20% reported taking prescription medications and 44% of nurses and 9% of midwives reported alcohol use as a sleep aid at least once during the study). Stress and workdays were significant predictors of sedative use. Overall, 22% reported being indifferent or mildly dissatisfied with their job. CONCLUSIONS: Sleep problems, high levels of stress and exhaustion and low job satisfaction are prevalent among nurses and midwives. The use of alcohol and sleeping pills as sleep aids, and the use of caffeine to help maintain alertness is also common. Nurses and midwives may use caffeine to compensate for reduced sleep, especially on workdays, and sleeping pills to cope with their daily work-related stress.

Efeito de filtros ópticos na função visual de espeleologistas

Speleologist’s perform their activity in demanding visual conditions of very low luminance - many visual tasks involve resolution of detail under conditions of low contrast. Work related conditions in a cave as exposure to heat, chemicals, dust and poor lighting conditions could influence the integrity of the visual system and predispose the eye to diseases that eventually affect vision. Poor lighting conditions cause a variety of symptoms of visual discomfort and may increase the risk of accidents. Good visual acuity is crucial for several and has an important role for safety purposes. The aim of this study was to evaluate lighting conditions and optical filters effects on visual performance in speleologists exposed to cave environments.

Alterations in psychosocial health of people affected by asbestos poisoning

OBJECTIVE To analyze the state of psychosocial and mental health of professionals affected by asbestos.METHODS A cross-sectional study was conducted with 110 professionals working in the Ferrolterra region of Spain, who were affected by asbestos poisoning. This group was compared with a group of 70 shipyard workers with no manifestation of work-related diseases. All the participants were male with a mean age of 67 years. This study was conducted in 2013, between January and June, and used the SCL-90 questionnaire by Derogatis as its primary measure for research. This questionnaire consists of 9 variables that measure psychosomatic symptoms. In addition, an overall index of psychosomatic gravity was calculated. The participants were also asked two questions concerning their overall perception of feeling good. Data were analyzed by ANOVA and logistic regression.RESULTS Participants affected by asbestos poisoning showed high occurrence rates of psychological health variables such as somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism, and global severity index.CONCLUSIONS Social interaction as a differentiating factor between workers affected by work-related chronic syndromes as compared to healthy participants will possibly aid in the development of intervention programs by improving the social network of affected individuals.

Occupational risk in a glass manufacturing industry unit

Risk assessment is one of the main pillars of the framework directive and other directives in respect of health and safety. It is also the basis of an effective management of safety and health as it is essential to reduce work-related accidents and occupational diseases. To survey the hazards eventually present in the workplaces the usual procedures are i) gathering information about tasks/activities, employees, equipment, legislation and standards; ii) observation of the tasks and; iii) quantification of respective risks through the most adequate risk assessment among the methodologies available. From this preliminary evaluation of a welding plant and, from the different measurable parameters, noise was considered the most critical. This paper focus not only the usual way of risk assessment for noise but also another approach that may allow us to identify the technique with which a weld is being performed.

Um olhar sobre a música produzida na ESML para clarinete solo e clarinete e eletrónica

O presente Projeto Artístico propõe como principal objetivo a divulgação de obras para clarinete solo e para clarinete e eletrónica produzidas no seio das classes de clarinete e composição da Escola Superior de Música de Lisboa. A preparação e montagem da obra de Edward Luiz Ayres d’Abreu, aqui realizada em estreia absoluta, pretende manter viva a continuidade de produção artística desta instituição a todos os níveis, neste caso, entre dois estudantes. Neste relatório estão registados os benefícios alcançados com o trabalho de pesquisa relacionado com os aspectos biográficos dos compositores, o contexto da criação das obras, assim como a análise e apuramento de questões interpretativas pouco utilizadas na música convencional como por exemplo, as técnicas clarinetísticas contemporâneas (glissando, frulato, vibrato, som e voz, multifónicos, micro-tons), a prática de música com eletrónica, ou a experiência inovadora da recriação musical em palco de uma partitura gráfica.
