As an Ergonomics Consultant you already know the value of limiting the duration of posture - even when that posture is optimal or non-optimal.
*NOTE: There is one hyper-counterintuitive piece of advice, so make sure you read this whole post to find out what it is!*
There's a long established a link between the highest reported discomfort and the most sedentary positions.
This is the most surprising thing about this research: Those who work in office jobs usually reported more discomfort when compared to other jobs that are more physically active.
How counter-intuitive is that?
One way I've told my clients to limit discomfort is to limit the amount of prolonged sedentary activity by incorporating some movement into the day. This is an obvious point and it's supported by past research.
Past research has indicated that movement is necessary to reduce discomfort, however there always seems to be conflicting information surrounding this.
There seems to be differing advice in how to limit the ergonomic risk in the office setting:
Research has always indicated a strong link between prolonged sitting and user discomfort, particularly in data entry and call centre operator positions. My hypothesis is that it psychosocial risks play a role in this too (but I'll save this in depth review until another time!).
Interestingly, even the most ergonomic posture held for significant portions of time would be considered to increase risk.
This is one of the reasons why a sit-stand workstation is so tempting for many; its purpose is to promote a dynamic movement by allowing the worker to switch between sitting and standing throughout the day wherever they see fit. Musculoskeletal complaints in sit-stand workstations tend to be lower when compared to a normal workstation.
The big concern with these workstations is that there has always been low compliance: in some offices, sit-stand workstations collect dust.
I've found that sit-stand workstations have been the most successful for those who sought out the workstation in the first place. For those who were ambivalent about sit-stand workstations, I have found that they are always very unlikely (past the first couple of months) to change between sitting and standing.
This study has found an extremely useful strategy that any office can easily incorporate:
Interestingly, even with taking more frequent breaks throughout the day, the researchers of this study found that productivity improved by 10%.
BOOM. There it is.
Do you think stretching should be part of ergonomics or it should be kept separate?
