Desk posture: what's worth changing, and what isn't

Most of the office workers we see for neck and back pain have already bought something: a lumbar cushion, a posture corrector, a standing desk they no longer stand at. Some of these help a little. None of them fix the underlying problem, which is usually spending eight hours in roughly the same position.

This article covers the four desk adjustments we think are worth five minutes of your time, a few things you can safely stop worrying about, and when pain is a sign to get checked rather than adjust your chair again.

The four adjustments that matter

These are listed in the order we'd tackle them. Each one takes a few minutes and costs little or nothing.

1. Raise your screen. If you work on a laptop, your head is probably tilted down for most of the day. Put the laptop on a stand or a stack of books so the top of the screen is roughly at eye level, and use a separate keyboard and mouse. This is the single change that helps the most people with neck pain.
2. Bring the keyboard closer. If you're reaching forward to type, your shoulders round and your upper back works harder. The keyboard should sit close enough that your elbows stay near your sides.
3. Set the chair height for your feet, not the desk. Feet should rest flat on the floor with your knees roughly level with your hips. If that leaves the desk too high, raise the chair and use a footrest. A sturdy box works fine.
4. Sit back in the chair. Use the backrest. Perching on the front edge means your back muscles hold you up all day. If the backrest doesn't fit the curve of your lower back, a small rolled towel is as good as a bought cushion.

What you can stop worrying about

• Sitting perfectly upright. Slouching for a while is not damaging your spine. Being stuck in any one position is the issue, upright included.
• The "right" chair. An expensive ergonomic chair is pleasant, but a normal office chair with a backrest and adjustable height does the job once it's set up properly.
• Standing all day. Standing desks are useful for variety. Standing for eight hours brings its own aches. Alternate between sitting and standing instead.
• Posture correctors and braces. They remind you to sit differently for a few days. They don't build the strength or habits that last.

A two-minute routine for the middle of the day

Do this once or twice a day, at your desk. None of it should hurt; if something does, skip it.

• Chin tucks: sitting tall, slide your chin straight back as if making a double chin. Hold for three seconds, ten times.
• Seated rotation: cross your arms, turn your upper body slowly to the left, then the right. Five each way.
• Shoulder blade squeeze: draw your shoulder blades back and down, hold for five seconds, ten times.
• Stand and lean back: hands on your lower back, gently arch backwards. Five times.

When to get it checked

Most desk-related aches settle within a few weeks once you change your setup and move more. Book an assessment if pain has lasted more than three or four weeks, keeps coming back, or wakes you at night.

See a doctor promptly if neck or back pain comes with numbness or weakness in your arms or legs, changes to bladder or bowel control, fever, or unexplained weight loss. These are uncommon, but they need medical attention rather than physiotherapy first.
