A simple, structured movement rule may be the key to easing back pain among office workers. A new Australian study found that alternating 30 minutes of sitting with 15 minutes of standing worked better than personalized plans for reducing pain and improving focus.
How to fix lower back pain?
Published in Applied Ergonomics, the three-month research included 56 desk workers already using sit-stand desks. All participants had lower back pain. Half of them followed a fixed 30:15 schedule, while the rest created personalized routines with the help of a physiotherapist.
The results showed that the fixed schedule group saw a larger drop in pain levels. Their worst daily pain went down by 1.33 points on a 10-point scale, and their average pain fell by 0.83 points. In comparison, the personalized group’s worst pain dropped by only 0.69 points, with little change in average pain.
Researchers also found that those who followed the fixed pattern reported better job focus and lower stress. They were more consistent, too, around 72% followed their schedule at least five times a day, compared to only 29% in the personalized group.
Why 30:15 ratio worked better
At first, allowing workers to set their own sit-stand times seemed sensible. Many used a method called “activity pacing,” where people plan breaks based on when pain starts. Some chose to sit for more than two hours or stand for 45 minutes at once. But this flexibility didn’t help.
The personalized group ended up standing about 72 minutes more per day than the fixed group, but the extra standing didn’t improve pain relief. Researchers say the fixed plan removed constant decision-making, helping workers stick to a steady rhythm.
The 30:15 ratio also balances comfort. Sitting for over 30 minutes is considered prolonged, while standing beyond 15 minutes can strain the back. This mix fits well with common office tasks like short meetings or replying to emails.

Frequent position changes didn’t hurt productivity either. Workers reported feeling more focused and less “present but in pain.” Both groups saw less neck pain and tried harder to break up long sitting spells.
Still, by the end of three months, adherence dropped in both groups, though the fixed schedule group remained more consistent. Working from home made things worse, as many lacked sit-stand desks.
For people spending hours at a desk, this study suggests that following a simple 30:15 sit-stand pattern may help reduce back pain better than trying to customize intervals. While the research had limits, such as a small sample and COVID-19 disruptions, it offers practical guidance: structure may matter more than flexibility.
