Posture & Ergonomics: who to see and what helps

Posture & Ergonomics · Kitchener, Waterloo & Cambridge

Posture is how you hold your body when you sit, stand and move; ergonomics is fitting your work to your body. Research does not support one “correct” posture, and the link between posture and pain is weaker than is commonly assumed. The advice Canadian sources give is to change position often and stay active. If pain or stiffness is the reason you are reading this, the first visit at CARESPACE is with a physiotherapist, a chiropractor or a kinesiologist.

What posture and ergonomics are

Posture is not a diagnosis, and neither is “bad posture”. Spines vary naturally in their curves, and comfortable positions differ from person to person. In 2019 a group of physiotherapy researchers summed up the evidence in seven points, which an NHS hospital trust has since turned into a leaflet; the first is that there is no “correct” posture.

Some patterns have names. Upper Crossed Syndrome is the head-forward, rounded-shoulder pattern and Lower Crossed Syndrome the tilted-pelvis one; both describe what a clinician sees and neither is a disease. A curve that is part of the spine’s structure is different: see Scoliosis, and the note on kyphosis below.

What people notice

• Rounded shoulders, a head carried forward, a rounded upper back or a deep curve in the lower back
• A stiff neck or numb legs after long spells of sitting, which are reported more often by people who work seated
• Discomfort that eases when you get up, move or change position

How each CARESPACE service helps with posture and ergonomics

Physiotherapy

A physiotherapist can watch how you sit, stand and move, and try other positions with you to see whether they ease your symptoms. Treatment leans on exercise, which has trial evidence for changing measured posture, and on variety, which is what Canadian workplace guidance advises: a program for the neck, shoulders and trunk, and more ways to sit and stand, not one position to hold.

Chiropractic

A chiropractor can examine how the joints of your neck and back move and treat the neck or back pain that often prompts the question about posture. None of our sources tested spinal manipulation as a way of changing posture itself, so expect exercise and advice about your day alongside any hands-on care.

Kinesiology

For posture, a kinesiologist can build a strength and stretching program of the kind the exercise trials used, and a practical plan for breaking up a seated day: when to stand, walk and stretch.

Occupational Therapy

The Ontario Society of Occupational Therapists describes occupational therapists assessing the work environment and recommending changes, such as a piece of equipment or a work routine with regular breaks built in, and consulting with employers about accommodations.

See our occupational therapy team →

Personal Training

The movement guidelines ask for muscle strengthening at least twice a week. A personal trainer can build and supervise that program once any pain has been assessed.

Massage therapy. None of the reviews we read tested massage as a way to change posture.

Where most people start

With pain, start with a physiotherapist or a chiropractor: both assess and treat at the first visit. Without pain, a kinesiologist is a good first visit for an exercise plan. If it is the workstation or the job that needs changing, ask about occupational therapy.

How your team works together

If more than one service is involved, a sensible order is assessment and treatment of any pain first, then a kinesiologist or personal trainer for strength and activity, with an occupational therapist where the workplace itself needs to change.

Browse by service: physiotherapists, chiropractors, kinesiologists, occupational therapists and personal trainers.

What to expect at your first visit

1. What you want from it: less pain, a better workstation, or a body that copes better with your day.
2. Your day: hours sitting, standing and driving, and how your desk is set up.
3. How you move: sitting, standing, bending and reaching, and whether a change of position changes what you feel.
4. A plan to leave with. If the visit is with a physiotherapist or a chiropractor, it includes treatment that day.

What shapes your posture

• How you are built. Variation in the curves of the spine is normal, and no single curve is strongly associated with pain.
• What your day asks of you. Computer work involves very few changes of position. So do plenty of days in this region: desk work in the tech sector, exam season at the universities and the college, a long drive on the 401.
• Mood and belief. Posture can reflect a person’s emotions, thoughts and body image.
• Pain, which can change how you hold yourself.
• The structure of the spine. Kyphosis, a hunched or rounded upper back, is often postural in teenagers but can come from the bones themselves. Loss of height in an older adult can be a sign of a spine fracture.

How posture is assessed

By watching how you sit, stand and move, and asking what your day involves. Screening people’s posture and movement has not been shown to prevent pain at work. If the shape of your spine has changed, a physician can arrange an X-ray.

What the evidence says about posture and ergonomics

• No single correct posture. The 2019 summary found no strong evidence that one optimal posture exists, or that avoiding “incorrect” postures prevents low back pain. It is a viewpoint from clinical researchers, not a trial, and the question is not settled: the NHS neck pain page still advises sitting upright.
• Posture and back pain: linked in some studies, not shown to cause it. A review of 41 systematic reviews found both positive and null associations between back pain and sitting, standing, bending and awkward postures, and no consensus on cause.
• The named patterns hold up no better. Adults with neck pain carry the head further forward on average, but the studies cannot show which came first, and people with back pain tend to have a flatter lower-back curve, not a deeper one. The two crossed-syndrome pages have the detail.
• Exercise changes measured posture. Across seven randomized trials with 627 participants there was strong evidence that exercise changes the angle of the head and neck, and moderate evidence that it may ease neck pain. The reviewers added that the link between head posture and pain “remains to be established”.
• Ergonomic equipment: one modest win. In a Cochrane review of 15 studies in 2,165 office workers, an arm support used with an alternative mouse reduced new neck or shoulder problems (moderate certainty, two studies). Either one alone did not; workstation adjustment and sit-stand desks had no effect on upper limb pain; and the evidence on ergonomic training was low to very low quality.
• Sit-stand desks have not been shown to reduce pain. In a second Cochrane review, two randomized trials of sit-stand desks found no significant short-term difference in low back or upper back symptoms, on low-quality evidence. Its authors add that some changes to the work environment, sit-stand desks among them, were suggestive of an improvement, and that larger and longer studies are needed.
• Movement has a national guideline behind it. The Canadian 24-Hour Movement Guidelines for adults advise limiting sedentary time to eight hours or less, breaking up long periods of sitting as often as possible, and muscle strengthening at least twice a week on top of 150 minutes of moderate to vigorous activity.

What you can do at home and at work

• Change position often. Canada’s occupational health and safety centre describes a good sitting position as one that lets you change position frequently, and suggests about five minutes of walking or similar activity for every 40 to 50 minutes of sitting.
• Set the chair: feet flat on the floor or a footrest, the backrest fitted to the hollow of your lower back, elbows at about a right angle and level with the work surface.
• Set the screen about an arm’s length away and just below eye level. Too high can cause neck and shoulder problems; lower it further if you wear bifocals or progressive lenses.
• At a sit-stand desk, alternate. Standing too long can lead to foot, knee, hip and back problems. Set the surface at about standing elbow height.
• Stretch at your desk with shoulder rolls or by gliding your head straight back without lifting your chin. You should feel a stretch, not pain; stop if it hurts.

How long change takes

Our sources give no timeline for changing posture, and the exercise research has mostly not looked at long-term effects. Kyphosis is a different matter: the NHS says physiotherapy exercises may help with back pain and stiffness but will not improve the curve or stop it getting worse. Most neck pain lasts only a few weeks, and back pain usually improves within a few weeks.

When it is not a posture problem

Call 911 for new problems walking, loss of bladder or bowel control, a sudden loss of coordination, for example with buttoning a shirt, or the signs of a stroke: a face that droops on one side, not being able to lift both arms and keep them up, or speech that is slurred or garbled.

Call 911 or go to an emergency department right away if back or buttock pain comes with any of these: pain, tingling, weakness or numbness in both legs; a loss of feeling in one or both legs, or around your genitals, anus or bottom; changes in your bladder or bowels, such as difficulty peeing, not being able to pee, or peeing or pooing yourself; changes in how your penis or vagina feels during sex, not being able to get or keep an erection, or not being able to orgasm; chest pain; or pain that started after a serious accident, such as a car crash. Do not drive yourself, and do not wait for an appointment: nobody at CARESPACE can rule these out.

The emergency departments in Waterloo Region are:

• WRHN @ Midtown (formerly Grand River Hospital), 835 King St. W., Kitchener
• WRHN @ Queen’s Blvd. (formerly St. Mary’s General Hospital), 911 Queen’s Blvd., Kitchener
• Cambridge Memorial Hospital, 700 Coronation Blvd., Cambridge

If you cannot get there safely, call 911.

Get medical advice the same day, from a physician or nurse practitioner or at an urgent care clinic, if you feel hot, cold, shivery or generally unwell; for severe neck or back pain that starts suddenly or is getting worse quickly; for heaviness or weakness in your arms or legs; for pins and needles in an arm together with neck or arm pain; or for pain between your shoulder blades.

See a physician or nurse practitioner if you think you or your child might have kyphosis, a hunched or rounded upper back; if your back has changed shape or has a lump or swelling; or if you have lost height. Osteoporosis Canada counts a measured loss of 2 cm, or 6 cm from the tallest you remember being, as a possible warning sign of a spine fracture, and many of those fractures are painless. Neck Pain and Back Pain list the other reasons to have pain checked.

Common questions

Is there a correct way to sit?

Not one that research supports. There is no strong evidence that an optimal posture exists, and comfortable positions vary between people. Change position often.

Does bad posture cause neck or back pain?

It is associated with pain in some studies and not in others, and reviews have found no agreement that it causes it. Pain can also change posture.

Are standing desks worth it?

They let you change position more often. In trials they have not been shown to reduce back symptoms, and standing too long brings problems of its own, so alternate.

Can posture be changed in an adult?

Measured posture, yes: in trials, exercise changed head and shoulder angles. Whether the change lasts, and whether it matters for pain, is less clear.
