Key Points Related Workstation Setup:
1. Jobs requiring the use of a computer or video display terminal can result in awkward and sustained postures which has been demonstrated as causes of work-related neck and shoulder pain (1).
2. Various studies have shown that those working with a computer experience neck and shoulder pain, with an incidence rate as high as 70% and 54% respectively (2, 3, 4, 5).
3. Previous research has shown a significant reduction in individual insurance claim costs among a group from an average of $15,141 to an average of $1,553 after ergonomic intervention was implemented (6).
4. There is inconsistency in research studies to demonstrate the benefit of a mouse based on neutral posture, arm support to reduce neck and shoulder region pain (7).
5. Supplementary breaks (e.g. 4 x 5 minute breaks in addition to conventional breaks) may reduce neck and arm discomfort among data entry workers (7). However, current available research is limited when investigating interventions aiming to increase standing or walking time to reduce musculoskeletal symptoms (13).
6. Neck/shoulder specific strengthening exercises have been shown to be effective in reducing neck pain intensity in office workers (8). Limited research suggests workstation adjustments may be effective in office workers that are symptomatic (8).
What About Sit-Stand Desks?
Physiotherapist’s are often asked about whether sit-stand desks can be helpful to reduce neck and shoulder symptoms.
1. Those who sit from 8 to 11 hours per day have a 15% increase in mortality rate in the next 3 years compared to those who sit for less than 4 hours per day (9).
2. A study found that the implementation of sit-stand desks decreased time spent sitting at work by 73 minutes per workday and increased standing time at work by 65 minutes per workday (10).
3. Another study comparing a group who transitioned to sit-stand desk (increasing their standing between 73 to 96 minutes per workday) time to those who continued at their desk seated showed similar levels of productivity (11). This suggests that a sit-stand desk does not decrease the worker’s ability to be productive at work
4. A review of all the studies investigating the effects of increased standing time related to pain and discomfort showed a significant effect for reducing lower back symptoms however research is limited to indicate it’s effect on neck and shoulder pain. Interestingly, some studies found lower limb pain (hips to feet) was increased related to increased standing time (9).
5. Therefore increasing standing time may be beneficial on improving our health in reducing conditions such as obesity, cardiovascular disease and type 2 diabetes (12) and reducing lower back pain however research is unclear on it’s effects on reducing neck and shoulder pain.
