    ABSTRACT: Body posture appears to influence fatigue and musculoskeletal complaints in musicians. Our aim was to determine energy expenditure and to investigate whether energy expenditure is affected by body posture in brass and woodwind instrumentalists. Eighteen musicians (10 women, 8 men; 6 brass, 12 woodwinds), with a mean age of 39 ± 14 years and mean body mass index of 23.8 ± 4.9 kg/m², played their instruments for 30 minutes twice: once in nonoptimized body posture (posture A), and once in a posture according to the postural exercise therapy method Mensendieck (posture B). Patients were randomized to the order of postures in a crossover design AB/BA. Playing sessions were preceded and followed by 60 minutes of rest. Energy expenditure was measured in a respiration chamber with indirect calorimetry. Basal metabolic rate was measured with a ventilated hood. Mean metabolic equivalents (MET) for playing a wind instrument in the sitting position in a nonoptimized posture and posture according postural exercise therapy were 1.69 (SD 0.18) and 1.80 (SD 0.22), respectively. Percent change between resting metabolic rate and total energy expenditure while playing was 32% (95% CI 25-39%) in posture B and 23% (95% CI 17-30%) in posture A (p = 0.021). Average physical activity while playing a wind instrument approximates 1.8 MET. Our data show an association between energy expenditure and body posture while playing a brass or woodwind instrument: playing a musical instrument in a posture according to postural exercise therapy leads to higher energy expenditure as compared to a nonoptimized body posture. These results suggest that fatigue and the general feeling of lack of energy after playing a musical instrument are not related to actual higher energy expenditure.

    ABSTRACT: To assess the course of nonspecific work-related upper limb disorders (WRULD) and the influence of sociodemographic factors, psychologic factors, and physical fitness on clinical status and functional disability. Retrospective cohort study with cross-sectional analysis among computer workers with several stages of nonspecific WRULD; average follow-up 4 years. Sociodemographic and medical characteristics were assessed based on medical records at onset and diagnosis. After informed consent at follow-up, participants received a questionnaire assessing psychologic and physical fitness characteristics. Outpatient department of rehabilitation medicine, University Hospital Maastricht; tertiary referral center for nonspecific WRULD. Computer workers (N=182) with nonspecific WRULD, 18 to 50 years, first consultation 1998 to 2001; those with specific WRULD and incomplete medical records and treatment charts were excluded. Not applicable. Stage of nonspecific WRULD (clinical status) and Disabilities of Arm, Shoulder and Hand questionnaire [DASH] (functional disability). A total of 104 patients (57%) returned the completed questionnaire at follow-up (November 2003). Fourteen percent developed chronic benign pain syndrome, 9% recovered. The remaining (77%) worsened slightly. A higher DASH score was associated with being elderly (unstandardized regression coefficient [B=.64]), being a woman (B=10.42), having a lower educational achievement (B=9.72), and poorer self-reported physical fitness level (B=1.68); lower educational achievement and poorer self-reported physical fitness were associated with a more severe clinical status. Psychologic factors did not influence disability or clinical status. The prognosis of computer workers with nonspecific WRULD is not favorable. Those with a lower educational achievement and poorer self-reported physical fitness are at risk for a more severe clinical status and functional disability. Being elderly and a woman are also risk factors for further disability. A prospective cohort study is needed to unravel these relationships. Nevertheless, computer workers with nonspecific WRULD should be encouraged to enter fitness programs.

    ABSTRACT: To assess the influence of work- and treatment-related factors on clinical status and functional disability in patients with non-specific work-related upper limb disorders (WRULD). 182 computer workers with non-specific WRULD, 18-50 years old, not having specific WRULD nor incomplete medical records. Retrospective cohort study among computer workers with non-specific WRULD; average follow-up 4 years. Medical records at time of diagnosis and during treatment period and a follow-up questionnaire were used. Setting: Outpatient department of Rehabilitation Medicine, University Hospital Maastricht. Non-specific WRULD (clinical status) and Disabilities of Arm, Shoulder and Hand (DASH) at follow-up. 103 patients (57%) returned the questionnaire. Of these, 14% developed a chronic pain syndrome, 9% recovered, 77% worsened slightly. None of the selected work- and treatment-related factors were significantly associated with clinical status. "Number of working hours per week before diagnosis" was negatively (b=-0.66, p=0.00) and "other therapies during treatment" (b=8.76, p=0.02) positively associated with DASH. Computer workers with non-specific WRULD have a poor prognosis. Working more hours before diagnosis seems not predictive for disability while having undergone other therapies during treatment period does. Prospective cohort studies are recommended to unravel the associations found.

    ABSTRACT: In computer workers psychological factors and physical fitness may play an important role in the onset and course of non-specific work-related upper limb disorders (WRULD) beyond socio-demographic factors. Based on our experiences in daily practice we assumed that pain catastrophizing and other psychological variables such as perfectionism, anxiety state and trait, and low physical fitness, are possibly associated with the occurrence of WRULD. We aim to study the association between pain catastrophizing, perfectionism, anxiety (state and trait), physical fitness, sex and level of education and the occurrence of WRULD, controlling for age as a confounder. Eighty-eight computer workers with early non-specific WRULD, who had been recruited for an intervention study, were compared with 31 healthy computer workers (controls) recruited from different departments of a university. This cross-sectional case-control study examined the influence of aforementioned variables on WRULD by means of logistic regression analyses. Among the different predictor variables investigated, pain catastrophizing (OR=1.37; 95%CI 1.17-1.59) and lower physical fitness had a positive relationship with WRULD (OR=0.65; 95%CI 0.48-0.87). According to this study, pain catastrophizing and lower physical fitness seem to be associated with early non-specific WRULD in computer workers. Prospective studies are needed to unravel these relationships.

    ABSTRACT: Are postural exercises delivered by Mensendieck/Cesar therapists more effective in decreasing pain, reducing disability and improving health-related quality of life in visual display unit workers with early non-specific work-related upper limb disorders than strength and fitness exercises delivered by physiotherapists? Randomised trial with concealed allocation and intention-to-treat analysis. Eighty-eight (6 drop-outs) visual display unit workers with early non-specific work-related upper limb disorders. One group received 10 weeks of postural exercises while the other group received 10 weeks of strength and fitness exercises. Pain was measured with a 10-cm visual analogue scale, disability was measured with the Disabilities of Arm, Shoulder and Hand questionnaire, and health-related quality of life was measured with the Short Form-36. Number of participants experiencing upper limb complaints was also collected. Outcome measures were collected at baseline and again at 3, 6, and 12 months. There was no significant difference in decrease in pain between the groups at 3 months (0.6 cm, 95% CI 0.0 to 1.2), 6 months (0.2, 95% CI -0.3 to 0.7), or at 12 months (0.1, 95% CI -0.6 to 0.8). Differences between the groups in upper limb complaints, disability, and health related quality of life were also small and not significant at any measurement occasion. Postural exercises did not result in a better outcome than strength and fitness exercises. However, 55% of visual display unit workers with early non-specific work-related upper limb disorders reported being free of complaints one year after both interventions were commenced.
