Transcript

Hello and welcome to the Spinemathema podcast. I’m Ahmed Sadek, a neurosurgeon, and this is our very first Spine Research Roundup.

The idea is simple. Every fortnight, I’ll pick out a handful of new studies that matter to people living with back and neck problems, and I’ll explain what they found in plain English. No jargon, and no hype.

This episode covers research published in the last couple of weeks of September and the first week of October twenty twenty six. I’ve also included one review from early September, because I think it answers a question a lot of you ask.

We’ve got five studies today. How much exercise you really need for long term back pain. When a slipped disc should be operated on. What actually helps a brand new bout of back pain. Mental wellbeing after surgery on the neck. And finally, whether back braces are worth it.

Let’s get started.

The first study is about exercise and chronic low back pain. By chronic, we simply mean pain that has gone on for more than about three months.

Exercise is one of the main treatments we recommend. But a question I hear all the time is, how much should I actually be doing? Is twenty minutes enough? Do I need to be in the gym every day?

A large international team set out to answer that. They brought together two hundred and thirty nine randomised trials of exercise in adults with chronic low back pain, and used a statistical method to work out which amount of exercise seemed to give the best results.

Here’s what they found. For reducing disability in the short term, the sweet spot looked like about four sessions a week, around twenty five minutes each, over roughly thirteen weeks. For reducing pain in the short term, it was about three sessions a week, around thirty minutes each, over eight weeks.

The really encouraging part is that low to moderate amounts of exercise gave most of the benefit. Doing a lot more didn’t add much.

Now, I want to be honest about the limits. Most of the trials had weaknesses in how they were run, and the researchers rated their confidence in the evidence as low to very low. The estimates for different doses also overlapped quite a bit, so there isn’t one magic number. And almost all the trials were in people with general back pain, not sciatica, so we know much less about exercise for nerve pain down the leg.

So what does this mean for you? You don’t need to exercise for hours. Three or four sessions a week of around half an hour is a realistic target. Side effects were mostly minor aches and strains. The best exercise is the one you’ll actually keep doing, whether that’s walking, swimming or a programme from a physiotherapist.

The second paper is a set of expert recommendations from AO Spine, which is a large international spine surgery organisation. The question is one I discuss with patients almost every week. When should a slipped disc in the lower back be operated on?

The group looked closely at six important studies, including several randomised trials, and agreed some practical advice.

The trials showed that people who would rather avoid surgery can often reach similar results in the long run without it, although recovery tends to be slower. The main benefit of early surgery is quicker relief of leg pain.

For people whose sciatica had lasted between four and twelve months, one trial found that a microdiscectomy, which is a small operation to remove the part of the disc pressing on the nerve, did better than carrying on with non surgical care at six months.

Where there is weakness in the leg or foot, timing matters more. Quicker surgery was linked with better nerve recovery, and the panel recommends aiming to operate within three days when the weakness is moderate or severe.

I should say this is an expert consensus built on a small number of studies, rather than a brand new trial. But it’s a useful summary of where the evidence stands.

What does it mean in practice? If you have sciatica without any weakness, there’s usually time to think. How long the pain has lasted, how bad it is, and what you would prefer should all guide the decision, and surgery becomes more worthwhile the longer the pain goes on.

New or worsening weakness is different, and should be checked promptly. And please remember, any change in your bladder or bowel control, or numbness around the saddle area, needs urgent medical attention, because that can be a sign of a rare but serious condition called cauda equina syndrome.

The third study is about acute low back pain, meaning pain that has been there for less than six weeks.

A team of researchers in the United States carried out a large review of the evidence to support a new guideline. They looked at one hundred and five studies covering how back pain is assessed and how it’s treated.

A few findings really stood out. First, early scans didn’t make any difference to pain or function in people without warning signs of something serious. That’s reassuring, because many people feel they need a scan straight away.

Second, the treatments with the best support were anti inflammatory tablets, muscle relaxants, spinal manipulation and mobilisation, acupuncture, simple advice to stay active, and early referral to a physiotherapist.

Third, paracetamol didn’t do better than a dummy tablet. And opioids, the strong painkillers, were no better than a dummy tablet at improving pain or function, but they did carry more risk of side effects.

They also found that how people cope with pain, their general health, and their mental health were the best predictors of who would go on to have long lasting pain.

Most of the improvements were modest, and they happened in the first few weeks.

So the message is a hopeful one. Most new back pain settles. Keep moving, take an anti inflammatory if it’s safe for you, and consider seeing a physiotherapist early. Scans are rarely needed at the start, and strong painkillers are unlikely to help much.

The fourth study moves us up to the neck. It’s about a condition called degenerative cervical myelopathy. That’s when wear and tear in the neck squeezes the spinal cord, which can cause clumsy hands, problems with balance, or numbness.

Surgery can stop the condition getting worse. But we know much less about how it affects mental wellbeing.

This Canadian study followed seven hundred and twenty nine people who had surgery and tracked their mental health over time. They found four different patterns.

About thirty eight percent had good mental health that stayed good. About thirty six percent stayed somewhere in the middle. About fourteen percent started low but improved after surgery. And about twelve percent stayed low throughout.

People in the good and improving groups were far more likely to feel satisfied with their surgery a year later than people whose mental health stayed low. The improving group also had bigger gains in disability and neck pain, even though the changes in nerve function were similar.

This was an observational study, so it shows a link rather than proving cause and effect. But the message for patients is clear. How you feel emotionally matters just as much as what the scans show. If you’re struggling with low mood or anxiety, before or after neck surgery, please tell your surgical team or your family doctor, your GP.

Our final paper is a Cochrane review. Cochrane reviews are among the most careful summaries of evidence we have. This one asked whether lumbar supports, belts and braces help people with chronic low back pain.

The reviewers found eight randomised trials, with five hundred and one people in total, all testing lumbar supports.

On their own, supports made little or no difference to pain or disability at three months. When they were added to anti inflammatory tablets, there may have been a small extra reduction in pain over three to four weeks. But the trials were small, most had weaknesses, and none of them reported on side effects.

The authors concluded there isn’t enough evidence to recommend lumbar supports routinely.

So, a support might feel comforting for a short while, but the evidence that it helps long term pain is weak. Building strength and confidence through gradual activity has much better support. If you’ve been given a brace after spinal surgery or for a fracture, that’s a different situation, so do follow your surgeon’s advice.

That brings us to the end of our first roundup.
