“…Supporting the forearm during computer work has been previously recommended as it promotes stability of the upper body with less strain on thoracic muscles such as trapezius, deltoid, and extensor digitorum (recorded using electromyography) (Delisle et al, 2006;Karlqvist, 1998;Nevala-Puranen et al, 2003;Saarni et al, 2007). However, in terms of postural benefit, the findings of this study support the previous literature in that forearm supported posture potentially promotes a more stooped head and shoulder posture (Bendix et al, 1985;Zacharkow, 1988).…”

“…This is somewhat in contrast to Chapter 6, where cultural differences in depression and anxiety symptoms appeared to be explained by other factors such as job strain and coping resources. These contrasting findings overall suggest that future studies will need to consider the potential effect of cultural differences when making inferences about findings observed in just one culture.Several ergonomic factors impacted on the maintenance of neutral posture in office workers.Interestingly the majority of participants (67.9%) in this study postured their forearms such that they were supported on the desk top while working with the mouse or keyboard.Supporting the forearm during computer work has been previously recommended as it promotes stability of the upper body with less strain on thoracic muscles such as trapezius, deltoid, and extensor digitorum (recorded using electromyography) (Delisle et al, 2006;Karlqvist, 1998;Nevala-Puranen et al, 2003;Saarni et al, 2007).

A longitudinal study of risk factors for non-specific neck pain in office workers

Neck pain at work is associated with reduced productivity, work absenteeism, and often requires treatment resulting in substantial costs to society. Working with a computer has been linked to the development of neck pain. Computer work is a constant factor in the office work environment, and within industry, office workers show the highest incidence of neck pain among all occupations. Therefore prevention of neck pain for office workers has become a priority. While there is an emerging body of literature investigating risk factors for the development of neck pain in office workers it is evident that major gaps still exist. For example, a current model exploring the aetiology of neck pain in workers (Bone and Joint Decade Task Force Model) has not sufficiently explained physical risk factors (workplace and worker), not explored the role of coping on the interaction between workplace psychosocial factors and psychological distress, and has not considered the impact of cultural diversity. The aim of this thesis is to address these deficits.In Study 1 physical risk factors for the development of neck pain in office workers were evaluated through a systematic review with meta-analysis. The review highlighted the poor standardization and quantification of working postural behavior that was mostly limited to subjective or momentary observational assessments.In Study 4 a direct quantitative measure of postural behaviour (percent of time spent in neutral upper body posture) with during office work using wireless sensors was developed with known measurement properties (good to excellent reliability) which could be included in the longitudinal study.A longitudinal study of 220 office workers (160 from Brisbane, Australia and 60 from Daegu, South Korea) without neck pain was recruited from industry. These office workers completed baseline self-report questionnaires measuring psychosocial factors, psychological distress, and coping resources. Follow-up measurements were taken over a 12 month period to evaluate the incidence of neck pain. Physical factors (postural behaviour during office work, neck range of motion, and upper body physical performance) were also evaluated at baseline. 3In Studies 5 and 6, measurements recorded at baseline were analyzed to clarify the physical and psychosocial characteristics of the office worker sample. Study 5 showed that the relationship between job strain and psychological distress (depression, anxiety, and stress symptoms) was moderated by coping strategies. In particular a greater dependence on escape coping strategies enhanced the effect of job strain on depression symptoms, which was in turn reduced when accompanied by higher levels of social support.Study 6 showed that postural behaviour of office workers was governed by multiple factors including both workplace and individual factors. In particular, ergonomic factors (e.g., higher desk height, greater distance on desk top between keyboard and the edge of desk), individual physical factors (e.g., less neck flexor strength/endu...

Work related neck pain is common problem in nurses, especially among those who are intensive computer users. It is generally agreed that the its etiology is multidimensional which is associated with 9%). Generally, the respondents were reported that their neck pain was associated with working hours on computer for more than 4 hours (56.7%); neck bending (56.4%) and Personnel shortage (53.2%). In bivariate; Chi square analysis, the result of present study indicated that there were seven factors significantly associated with neck pain i.e. age, BMI, physical exercises, night shifts, neck bending, prolonged working hours on computer and personnel shortage.Further analysis, by using multiple logistic regression showed that age groups [30][31][32][33][34][35][36][37][38][39]) and [40][41][42][43][44][45][46][47][48][49] physical exercises (p= 0.025,, working time on computer (p= 0.029, night shifts (p= 0.001, personnel shortage (p= 0.005, and neck bending (p= 0.013,

“…In summary, according to the results of our study, this represents change in the system away from coercion towards one which encourages voluntary action, i.e., Näppärä. There is a great demand for (a) new methods using techniques which assess physical exposure to workrelated musculo skeletal risks and (b) practical exposure assessment tools that meet the needs of ergonomics experts and practitioners [17,18,19,20,21]. Moreover, Näppärä can be used by both OHC professionals and computer operators.…”

Employers and workers need concrete guidance to plan and implement changes in the ergonomics of computer workstations. The Näppärä method is a screening tool for identifying problems requiring further assessment and corrective actions. The aim of this study was to assess the work of occupational safety and health (OSH) government inspectors who used Näppärä as part of their OSH enforcement inspections (430 assessments) related to computer work. The modifications in workstation ergonomics involved mainly adjustments to the screen, mouse, keyboard, forearm supports, and chair. One output of the assessment is an index indicating the percentage of compliance items. This method can be considered as exposure assessment and ergonomics intervention used as a benchmark for the level of ergonomics. Future research can examine whether the effectiveness of participatory ergonomics interventions should be investigated with Näppärä.
