- Disorders in the musculoskeletal system have been associated with a high physical workload as well as psychosocial and individual factors. It is however not obvious which of these factors that is most important to prevent. Musculoskeletal disorders in neck and upper extremity was assessed by interview and clinical examination in 79 teachers and 93 assisting nurses, all females. Psychosocial work environment was assessed by questionnaire. The physical workload was recorded by technical measurements of postures, movements and muscular load, in 9 teachers and 12 nurses. The physical workload was lower among the teachers, but they had a more demanding psychosocial work environment. Among the nurses, but not in the teachers, the neck-shoulder disorders were associated with a high body mass index (BMI). The teachers reported neck-shoulder complaints to a higher extent than the nurses, but had much lower prevalence of diagnoses in the clinical examination (12% vs. 25%; POR 0.3 CI 0.1 - 1.2; adjusted for age and BMI). The results suggest that adverse psychosocial conditions among the teachers give rise to a different kind of pain in the neck-shoulder region than from physical overload, troublesome but not as severe as the one afflicting the nurses.

- This study was performed between 2004 and 2011 at mail sorting facilities in Sweden. During this time, different interventions were performed. The first was a lighting intervention that had a positive impact on the postal workers, especially those with eyestrain. A new lighting system also improved the illuminance and gave better light distribution. The second intervention involved new personal spectacles for the postal workers who needed them and this had a positive effect on eyestrain. The third intervention involved a specific type of sorting spectacles for the postal workers who already used progressive lenses privately. The reading distances that the postal workers had while sorting the mail was inverted to the distances in their regular progressive lenses. The new sorting spectacles had a positive effect on head postures and on muscular activity.

- BACKGROUND: Sorting mail into racks for postmen is visually demanding work. This can result in backward inclination of their heads, especially more pronounced for those who use progressive addition lenses. OBJECTIVE: To evaluate the effects of customized working spectacles on the physical workload of postmen. METHODS: Twelve male postmen sorted mail on two occasions: once using their private progressive spectacles and once using customized sorting spectacles with inverted progressive lenses. Postures and movements of the head, upper back, neck, and upper arms were measured by inclinometry. The muscular load of the trapezius was measured by surface electromyography. RESULTS: With the customized sorting spectacles, both the backward inclination of the head and backward flexion of the neck were reduced (3 degrees), as well as the muscular load of the right upper trapezius, compared to sorting with private spectacles. However, with the sorting spectacles, there was a tendency for increased neck forward flexion, and increased sorting time. CONCLUSION: The reduction in work load may reduce the risk for developing work-related musculoskeletal disorders due to the positive reduction of the backward inclination of the head. But the tendency for increased neck forward flexion may reduce the positive effects. However, the magnitude of the possible reduction is difficult to predict, especially since quantitative data on exposure-response relationships are unknown. Alternative working spectacles with inverted near progressive lenses ought to be evaluated. They should still result in a positive reduced backward inclination of the head and may not cause any increased forward flexion.

- Objective. Formal joint assessments are critically important to improve rheumatological care of patients with RA. The aim of this study was to determine the usefulness of patient-recorded 28 tender joint counts (TJCs) and swollen joint counts (SJCs) using a tablet personal computer and to explore the possibility of using patient-recorded data to calculate 28-joint DAS (DAS-28) and EULAR response. Methods. Forty-seven patients were included before initiation of adalimumab therapy and assessed at baseline and after 3 months. SJC and TJC were registered by the patients and thereafter by an experienced rheumatology specialist. Changes were correlated using Spearman’s rank correlation test. Results. The correlations between SJC and TJC derived by the physician and the patient at baseline were excellent (r = 0.78 and 0.87, respectively P < 0.01 for both). After 3 months, the correlations were less strong (0.645 and 0.745, respectively, P < 0.001 for both). When using the patient-derived SJC/TJC for calculation of the DAS-28 (patDAS-28), similar values were obtained, and correlations between DAS-28 and patDAS-28 were excellent (r = 0.91 at baseline, r = 0.90 at 3 months). According to the EULAR response criteria, the percentage of responders at the group level was nearly identical, although there was some disagreement at the individual level when DAS-28 and patDAS-28 were used to determine response to therapy. Conclusion. Patient-reported SJC and TJC can in research settings be used instead of physician-reported ones. Patient-derived SJC and TJC may also make it possible for rheumatologists to obtain quantitative joint count recordings much more frequently than is feasible for traditional joint counts.
