Pilates for sciatica: what helps, which moves to change, and when to stop

Keep moving

The NHS says to "start gentle exercise as soon as you can", and that "even if moving hurts, it's not harmful". NICE recommends carrying on with your normal activities.

Sources 1, 2

Pilates is one of NICE's kinds of exercise

NICE suggests a group exercise programme for back pain with or without sciatica, and its guideline counts Pilates as "biomechanical" exercise, alongside core stability work.

Sources 2, 3

The evidence in sciatica is thin

NICE's evidence review found no trials of mind-body exercise in sciatica, the Cochrane review of Pilates for back pain left out trials that included people with nerve root problems, and only two small trials have tested Pilates in people with a slipped disc.

Sources 3, 4, 5, 6

Exercise helps leg pain a little

Structured exercise eased leg pain a little more than advice to stay active in the short term, with no difference later on. Physiotherapy in general hasn't been shown to beat other care, in trials at high or unclear risk of bias.

Sources 7, 8

Let your leg guide you

Keep moves that ease your leg or leave it the same, and make smaller or leave out moves that send pain further down it (our suggestion, following our sciatica guide). In a trial of 181 people with severe sciatica, exercises chosen by how their symptoms responded did better than sham exercises.

Know the red flags

Call 999 or go to A&E for sciatica in both legs, numbness around your genitals or bottom, or new trouble peeing or pooing. Don't drive yourself.

What it is

"Sciatica happens when the sciatic nerve, which runs from your lower back to your feet, is irritated or compressed", the NHS says. It usually affects your bottom and the back of one leg, often down to the foot and toes: a sharp or burning pain, pins and needles, numbness or weakness, often worse when you move, sneeze or cough. Back pain is usually milder than the leg pain, and "You probably do not have sciatica if you only have back pain".

Causes and how long it lasts

A slipped disc is the most common cause. Others include spinal stenosis (narrowing of the space the nerves pass through), a vertebra slipping out of place (spondylolisthesis) and back injuries. Sciatica "usually gets better in a few weeks to a few months but can last longer", and it can come back.

Why straight legs can pull on a sore nerve

Doctors test for an irritated nerve root by lifting your straight leg while you lie on your back (the straight-leg raise), or by straightening your knee while you sit slumped (the slump test). In people having surgery for a slipped disc, the straight-leg raise was positive in 92%. Pilates moves that fold forward over straight legs put the nerve in a similar position.

A direction that eases the leg

In some people, repeating a movement in one direction, often bending back, eases the leg pain or draws it up towards the back (centralisation). About 40% of people with back pain centralise, and about 2 in 3 have a direction of movement that eases their pain. It's a good sign for recovery, though it hasn't been shown to pick out who does better with a matching exercise, and clinicians often disagree about it.

NICE: stay active, and consider group exerciseStrong evidence

NICE recommends advice to help you manage back pain with or without sciatica yourself, including "encouragement to continue with normal activities". It says to "Consider a group exercise programme (biomechanical, aerobic, mind-body or a combination of approaches)" for a flare-up of back pain with or without sciatica, taking your needs and preferences into account. Hands-on treatment, such as manipulation or massage, should only be part of a package that includes exercise.

Source 2

Where Pilates fits in NICE's termsStrong evidence

NICE's full guideline defines biomechanical exercise as exercise aimed at improving how the spine moves, including strengthening, stretching and "motor control exercise (including core stability programmes and Pilates)". Its evidence review found "No evidence ... for the use of mind-body exercise in the sciatica population", and inconsistent evidence for mixed exercise programmes in sciatica.

Source 3

The NHS: start gentle exerciseStrong evidence

For sciatica, the NHS says to carry on with your normal activities as much as possible, try regular exercises, "start gentle exercise as soon as you can" and not to sit or lie down for long periods. For back pain, it says walking, swimming, yoga and Pilates may help, and for a slipped disc, "The type of exercise is not important as long as it does not cause pain or make your back pain worse".

Sources 1, 12, 13

Where advice on pain differs

The NHS sciatica page says moving isn't harmful even if it hurts, while the safety notes on NHS exercise videos, including its sciatica and back pain Pilates videos, say to stop if you feel any pain. Our sciatica guide's rule sits between them: moving may hurt, but the pain shouldn't spread down your leg.

Sources 1, 14, 15

Little direct trial evidenceStrong evidence

NICE found no trials of mind-body exercise in sciatica. The 2015 Cochrane review of Pilates for back pain (10 trials, 510 people) found Pilates eased pain more than minimal care, but it left out trials in which more than 5% of people had nerve root problems, so it says nothing direct about sciatica.

Sources 3, 4

Two small Pilates trials in slipped discsMixed evidence

In 54 people aged 30 to 60 with a bulging disc and back and leg pain for at least 6 weeks, physiotherapist-led Pilates 3 times a week for 6 weeks cut a disability score from about 29 to 15, against about 26 to 23 without exercise, and eased pain. People were put into groups in the order they arrived, the groups differed at the start, and nobody was followed up after 6 weeks.

In 45 women with a slipped disc, adding Pilates to water exercise 3 times a week for 8 weeks improved mobility, disability and quality of life more than water exercise alone. Both trials were small and short.

Sources 5, 6

A Pilates trial NICE counted under sciaticaMixed evidence

NICE listed one trial of Pilates or stationary cycling in 64 people under back pain with sciatica. Pilates lowered disability more at 8 weeks, but not at 6 months. The trial itself describes long-term back pain without a specific cause, and the Cochrane review, which left out trials with nerve root problems, included it, so it says little about sciatica.

Sources 16, 3, 4

Exercise eases leg pain a little, at firstEmerging evidence

In 5 trials, structured exercise eased leg pain by about 11 points out of 100 more than advice to stay active in the short term (low-quality evidence), with no difference in disability, and no difference in the long term (moderate-quality evidence).

Source 7

Other treatments: low certainty tooMixed evidence

A 2023 review of 18 trials (2,699 people) found physiotherapy no better than control treatments for pain or disability, and all the trials were at high or unclear risk of bias. Two 2025 reviews of 40 and 50 trials of non-surgical treatments found the evidence for every treatment was very low confidence.

Sources 8, 17, 18

Exercises chosen by how your leg respondsEmerging evidence

In a Danish trial of 181 people with pain below the knee, many of whom would usually be offered surgery, exercises chosen by how their symptoms responded did better on most measures than sham exercises, after an average of about 5 sessions. Both groups got information and advice to stay as active as possible "but to reduce activity if leg pain increased".

Source 9

After disc surgeryMixed evidence

A 2024 review of rehabilitation in the first 3 months after disc surgery found one trial in which adding Pilates to routine care and cognitive behavioural therapy improved function straight after the programme. No studies in the review looked at side effects. Follow your surgical team's timetable; our guide to exercise after back surgery has more.

The rule

A little discomfort while you move is fine: the NHS says moving isn't harmful even if it hurts. But make a move smaller, or leave it out for now, if it sends pain, tingling or numbness further down your leg, or leaves your leg worse the next day (our suggestion, following our sciatica guide).

Sources 1, 9

Find the direction that eases itEmerging evidence

Try a gentle back bend, such as the sphinx, and a gentle knee to chest, and keep whichever eases your leg or draws the pain up towards your back. Easing in one direction is a good sign for recovery, though it hasn't been shown to pick out the best exercise.

Source 11

Why we suggest changing straight-leg foldsMixed evidence

Our suggestion, based on how doctors test for an irritated nerve root: while your leg pain is bad, swap forward folds over straight legs for knees-bent versions. No trial has tested this, and the one Pilates trial in people with a slipped disc used the saw and the spine stretch in its cool-down, with no harm reported. So test each fold on its own, and keep it if your leg doesn't mind.

Sources 10, 5

No need to braceEmerging evidence

In a trial of 152 people with long-term back pain, being taught to keep the tummy relaxed and move smoothly during Pilates gave slightly better disability results than being taught to hold the core tight. Breathe and move; you don't need to brace all the time.

Source 20

Forward folds over straight legs

Bend your knees, sit on a block, or leave them out for now:

• the spine stretch forward and the saw: bend your knees or sit on a block
• the single and double straight-leg stretches: use the knee fold instead
• the teaser

Source 10

Rolling and heavy curling

Leave out the roll-over, jack knife, rolling like a ball, open-leg rocker, corkscrew, neck pull, boomerang, control balance, crab and rocking. For the roll-up, use the half roll back if rounding doesn't spread your leg pain. The NHS says the type of exercise matters less than whether it causes pain or makes it worse.

Source 13

Tummy work with the legs out long

Do the hundred and the double leg stretch with your knees bent and your head down, or use the knee fold and dead bug heel taps instead.

Source 20

Single-leg circles

Bend the other knee and keep the circles small, or leave them out if they pull down your leg.

Source 10

In the first days and weeks

Keep moving: short walks of 5 to 15 minutes several times a day, and the lying or seated nerve slider, 10 slow repetitions 2 to 3 times a day, the move page's dose from an NHS service. Our sciatica guide sets these out in stages.

Source 1

Adding Pilates

The Pilates trial in slipped discs used physiotherapist-led sessions of 45 to 60 minutes, 3 times a week for 6 weeks, starting with a one-to-one session. Our editorial starting point: the 15-minute Pilates for back pain routine 2 or 3 times a week, with the swaps above, once walking doesn't spread your leg pain.

Classes

NICE suggests group exercise, and a physiotherapist-led (clinical) Pilates class is closest to the trial. Tell the teacher about your sciatica, and ask for knees-bent versions while your leg is sore.

Go to A&E or call 999 if you

The NHS says to go to A&E or call 999 (911 in the US) if you:

• have sciatica on both sides
• have weakness or numbness in both legs that's severe or getting worse
• have numbness around or under your genitals, or around your bottom (anus)
• find it hard to start peeing, can't pee or can't control when you pee, and this isn't normal for you
• don't notice when you need to poo or can't control when you poo, and this isn't normal for you
• have changes in how your penis or vagina feels during sex, can't get or keep an erection, or can't orgasm

Sources 1, 12

Don't drive yourself

These can be signs of a serious back problem, cauda equina syndrome, which needs treating in hospital as soon as possible. "Do not drive to A&E. Ask someone to drive you or call 999 and ask for an ambulance."

Get an urgent GP appointment or call NHS 111

If you have back pain and feel hot, cold, shivery or generally unwell, or the pain is severe and started suddenly or is getting worse quickly. Our sciatica guide lists other same-day signs, such as a foot that drags or slaps down as you walk.

See a GP

If your sciatica hasn't improved after a few weeks of looking after it at home, is getting worse, or is stopping you doing your normal activities. In many areas you can refer yourself to NHS physiotherapy for back problems.

"Pilates cures sciatica"Strong evidence

The evidence in sciatica is thin: NICE found no trials of mind-body exercise in sciatica, the Cochrane Pilates review left out people with nerve root problems, and the two small Pilates trials in slipped discs had no long-term follow-up. Most sciatica gets better in a few weeks to a few months.

Sources 3, 4, 5, 1

"Rest until it goes"Strong evidence

The NHS says not to sit or lie down for long periods, because "even if moving hurts, it's not harmful and can help you get better faster". NICE advises carrying on with normal activities.

"Some Pilates moves are banned with sciatica"Mixed evidence

No trial shows that a particular move harms sciatica, and the one Pilates trial in slipped discs used forward bends in its warm-up and cool-down. What helps is choosing moves by how your leg responds.

"You must brace your core all the time"Emerging evidence

In a trial of 152 people with back pain, Pilates with a relaxed tummy did slightly better for disability than Pilates with the core held tight.

"Stretch the nerve hard to free it"Mixed evidence

Straight-leg positions put an irritated nerve root on stretch, which is how doctors test for it. The nerve sliders in our sciatica guide move the nerve gently without holding a stretch.
