Pain from Desk Work

The neck, shoulders and low back that start complaining after eight hours at a screen. This page covers what has actually been shown to help — and why it is not a new chair.

About sitting "correctly"

Your posture is not the main cause

This contradicts almost everything you have been told, so let's go straight to the data. A 2019 meta-analysis of 15 studies did find an association between forward head posture and neck pain in adults — but the association was weak, and in adolescents it was absent altogether. A review of systematic reviews on spinal posture and low back pain concluded there is no consensus on causality. So posture is not irrelevant — it is simply a much smaller factor, and a far less certain one, than it is usually sold as.

What does hold up: sustained slumped sitting does provoke neck pain and raises shoulder muscle activity — that has been shown in controlled trials. The distinction is subtle but it matters. What loads you is not the shape of the posture but how long you hold any position without changing it.

That is good news, because changing how often you move is far more achievable than holding a "correct" posture for eight hours — something nobody actually manages.

The change with the best evidence: two- to three-minute breaks

A 2022 systematic review of six trials found that short breaks — around two to three minutes every half hour — reduced neck, shoulder and lower back discomfort in desk workers. That review did not test whether sitting posture changed the result; a separate review found the strongest evidence for breaks that involve actually changing position. Not long breaks, not elaborate stretches. Stand up, walk to the water cooler, roll the shoulders a few times, come back.

If you change one thing after reading this page, make it that. Most people can fit it between meetings without anyone's permission and without buying anything.

On standing desks: a Cochrane review found sit-stand desks cut workplace sitting by roughly 84 to 116 minutes a day in the short term (up to three months), on low-quality evidence; over the medium term the difference roughly halves. That review did not assess pain as an outcome, so it has nothing to tell us about reducing back pain. So buy one if you want to sit less; do not buy one expecting the pain to go.

What we work on in the clinic

Once the pain is there, changing habits alone is often not enough — muscle and tissue that have become sensitive need settling first. We assess neck and back movement, the strength and endurance of the muscles that hold you upright, how you breathe when you concentrate, and whether a nerve is involved if the pain travels.

After that the program is usually simple and staged: endurance work for the neck and upper back, hip strength so your low back is not doing all the work when you sit, and variety in working positions. We will also look at a photo of your desk — there is often one thing you can change for free, like screen height or where the mouse sits.

What we do not promise: a particular chair, a particular cushion, or a posture brace that makes the pain go away.

What to bring

  • A photo of your desk from the side, while you are sitting as you normally do
  • How many hours a day at a screen, and how long you go without standing
  • When it hurts most — morning, late afternoon, or oddly at the weekend
  • What you have already tried: chairs, cushions, posture braces, massage
  • If the pain travels into an arm or leg, how far it goes

Frequently asked questions

Do I need an expensive ergonomic chair?

A decent chair helps, but getting the ergonomics right on its own gives inconsistent results in the research, on moderate-to-low quality evidence. Even the most expensive chair is hard on your body if you sit in it for eight hours without moving. On a limited budget, prioritise getting the screen to eye height and an alarm to stand every 30–45 minutes — both free.

People say I slouch. Is that the cause?

Most likely not the main cause. The research has not found that people with rounded shoulders or a forward head get pain more often. What matters more is how long you hold one position, how strong your muscles are and how much endurance they have, and factors like sleep, stress and activity level. We will still look at your posture — not to judge its shape, but to learn which positions you avoid and why.

I use a standing desk and it still hurts. Why?

Because standing still for three hours is also one position held for a long time. Sit-stand desks have been shown to cut sitting time, but there is not yet enough evidence that they reduce back pain. The benefit shows up if you actually alternate — sit, stand, walk — not if you swap eight hours of sitting for eight hours of standing.
