Musculoskeletal Symptoms Among Finnish Professional Orchestra Musicians

BACKGROUND: The prevalence of musculoskeletal symptoms is high among professional musicians (73-88%). AIMS: We investigated the prevalence of musculoskeletal symptoms in Finnish symphony orchestra musicians. We compared individual instruments as well as the perceived demands of orchestral programs and difficulties in recovering after performances. METHODS: In this cross-sectional questionnaire 920 of 2,785 members of the Finnish Musicians Union (33%) completed the questionnaire, including 361 full-time members of symphony orchestras. Questions about pain symptoms and frequency were based on the national survey done in 2011. RESULTS: Among the 361 full-time orchestra musicians, those playing all instruments experienced frequent pain, both in the last 30 days and exceeding 30 days in the last 12 months, in their neck or upper extremities. Female musicians experienced significantly more neck (69%), elbow (31%), and wrist (30%) pain than males (neck 52%, elbow 23%, wrist 19%). The profiles varied according to the different instruments and their playing positions. Musculoskeletal symptoms correlated with perceived demand of the orchestral program and difficulties in recovering after performances. Professional musicians experienced nearly twice as often neck pain in the last 30 days (female musicians 69%, male musicians 52%) than persons of the same age in the Finnish working population (female 41%, male 27%). CONCLUSION: Symphony orchestra musicians experience nearly twice as much musculoskeletal symptoms of the neck and upper extremities as others their age. To prevent musicians¿ playing-related problems, special emphasis should be focused on recovery after concerts, including the special demands of different composers and the frequency of rehearsals and performances.

Conception des équipements de travail et prévention des TMS Complémentarités et points d’ancrage des démarches

Après un bref rappel sur les démarches de prévention des TMS et de conception des équipements de travail, cet article présente dans un premier temps les difficultés constatées vis-à-vis de leur articulation. Il propose ensuite des « points d’ancrage » pour accompagner, dans un cadre participatif et multidisciplinaire, les temps de recherche de solutions et de décisions. Les interactions ainsi obtenues favorisent le partage des référentiels et explicitent les processus de décision. Elles fonctionnent à l’identique d’un « moteur méthodologique » qui implante la problématique des TMS à chaque séquence de la conception.
Cette approche doit permettre aux petites et moyennes entreprises (PME) de trouver des réponses à leurs besoins en matière de prévention des TMS très en amont dans le processus de conception d’un équipement de travail. Elle contribue en effet à une meilleure compréhension des leviers favorisant la prise en compte des TMS et à l’élaboration de nouvelles références d’actions vis-à-vis du processus de conception.

Are work organization interventions effective in preventing or reducing work-related musculoskeletal disorders?

A systematic review of the literature
Objectives: We sought to determine whether interventions that target work organization or the psychosocial work environment are effective in preventing or reducing work-related musculoskeletal disorders (WMSD) compared to usual work.
Methods: We systematically reviewed the 2000–2015 English and French language scientific literature, including studies evaluating the effectiveness of an organizational or psychosocial work intervention on incidence, prevalence or intensity of work-related musculoskeletal pain or disorders in the neck, shoulders, upper limbs and/or back or of work absence due to such problems, among non-sick-listed workers. We excluded rehabilitation and individual-level behavioral interventions and studies with >50% attrition. We analyzed medium- and high-quality studies and synthesized the evidence using the Grading of Recommendations Assessment, Development & Evaluation (GRADE) approach. An analysis of key workplace intervention elements supplemented interpretation of results.
Results: We identified 884 articles; 28 met selection criteria, yielding 2 high-quality, 10 medium-quality and 16 low-quality studies. There was moderate evidence that supplementary breaks, compared to conventional break schedules, are effective in reducing symptom intensity in various body regions. Evidence was low- to very low-quality for other interventions, primarily due to risk of bias related to study design, high attrition rates, co-interventions, and insensitive indicators. Most interventions lacked key intervention elements, such as work activity analysis and ergonomist guidance during implementation, but the relation of these elements to intervention effectiveness or ineffectiveness remains to be demonstrated.
Conclusions: Targeting work–rest cycles may reduce WMSD. Better quality studies are needed to allow definitive conclusions to be drawn on the effectiveness of other work organizational or psychosocial interventions to prevent or reduce WMSD.
