Exercise may ease office workers' back pain, but the proof is thin

Office workers spend most of the day sitting, and chronic low back pain is one of the most common complaints in that group, making it a major occupational health concern. Exercise therapy is widely recommended for chronic low back pain in general, yet surprisingly few studies have tested it specifically in desk-based workers. This review asked whether exercise actually helps this particular population, and not just with pain: it also looked for effects on daily function, physical activity levels and the ability to do the job.

The authors ran a systematic review and meta-analysis of randomised controlled trials, searching electronic databases for studies published up to 31 March 2025. Four trials qualified, covering 263 office workers with chronic low back pain. The primary outcomes were pain intensity and work productivity, with functional disability and physical activity level as secondary outcomes. Results were pooled using a random-effects model, and the certainty of the evidence was assessed with the standard GRADE approach.

At short-term follow-up, the pooled estimate suggested that exercise interventions may reduce pain intensity compared with control conditions. That positive signal came heavily qualified: the reviewers rated the certainty of the pain evidence as very low. Evidence for functional disability and physical activity level was judged insufficient to draw conclusions. Most strikingly, none of the included trials assessed work productivity or presenteeism using validated instruments, so the work-related question the review set out to answer remains completely open.

Exercise is already the standard recommendation for chronic low back pain, so a positive short-term signal is consistent with the wider evidence base. What this review adds is a warning about how thin the office-worker-specific literature is: four small trials, very low certainty, and a total absence of validated work outcomes. It leaves open whether pain relief translates into better function, more activity or fewer lost working hours, and whether any benefit lasts. The authors call for high-quality, long-term trials that treat productivity as a primary outcome.

If desk work has left you with persistent lower back pain, this review offers a modest reason for optimism about exercise: the pooled signal pointed towards less pain in the short term. It is equally a reason to keep expectations realistic, because the evidence behind that signal is weak and says nothing yet about long-term relief or performance at work. Nothing here argues against moving more; it simply shows the science specific to office workers has not caught up with the advice.
