Study design: Individual participant data meta-analysis of 21 randomised trials (4,223 participants)

What the study looked at

Chronic low back pain is one of the most common reasons people seek hands-on care, and spinal manipulative therapy, the manual techniques used to move the joints of the spine, is one of the more debated treatments for it. This was a big, careful attempt to settle how well it works.
Rather than just pooling published summaries, the researchers gathered the raw data on individual patients from 21 randomised trials, 4,223 people in all. That kind of individual participant data meta-analysis is about as robust as this evidence gets.

Why this matters to us

Low back pain is bread-and-butter work in any clinic. Knowing how spinal manual therapy stacks up against other recommended treatments helps us set honest expectations.

What the treatment involved

Spinal Manipulative Therapy

Manual techniques applied to the spine, including manipulation and mobilisation, aimed at improving movement and reducing pain in the lower back.

Compared With Recommended Care

The trials compared spinal manual therapy against other recommended treatments for low back pain, such as exercise and standard care, and tracked pain and function over time.

What the results showed

The headline is a fair and useful one: spinal manual therapy worked about as well as the other recommended options.

As Good as Other Care

Spinal manual therapy gave similar pain relief and function to other recommended treatments at every time point.

Holds Up Over Time

The benefits were maintained out to 12 months, not just straight after treatment.

Moderate-Quality Evidence

The evidence was rated moderate quality for function, which is reasonably solid ground.

A Valid Option

Taken together, it supports spinal manual therapy as a legitimate choice, not a second-rate one.

Key finding in plain terms

Spinal manual therapy was neither a miracle nor a dud. It performed on par with other recommended treatments for chronic low back pain, and the benefit lasted up to a year. That makes it a reasonable option to choose based on your preference.

What this means for myotherapy and physiotherapy

This backs hands-on spinal treatment as a genuine, evidence-supported choice for chronic low back pain, sitting alongside exercise rather than competing with it. Because it works about as well as other recommended care, your preference and how you respond can reasonably guide the plan.
In practice we rarely use manual therapy on its own. Pairing it with exercise and activity advice is how we aim for results that hold, and this review supports manual therapy being part of that mix.

Clinical relevance by discipline

Myotherapy

Supports hands-on spinal and soft-tissue work as an effective option for chronic low back pain, alongside exercise.

Physiotherapy

Backs spinal manipulation and mobilisation as being as effective as other recommended care, best combined with exercise.

Remedial Massage

Reinforces manual treatment of the low back and surrounding muscles within a broader plan.

Dry Needling

Complements needling of tight lower-back muscles as part of a combined approach.

Limitations to be aware of

Only about half of the eligible trials shared their individual patient data, which can introduce some bias, and there was variation between studies that could not be fully explained. Reporting of side effects was limited across the trials, though serious problems from this kind of care are uncommon.
As always, low back pain has many causes. If you have significant leg symptoms, numbness, or any red-flag signs, it is important to be assessed by a doctor.

Summary

Pooling individual data from 21 trials and over 4,000 people, this meta-analysis found spinal manual therapy as effective as other recommended treatments for chronic low back pain, with benefits lasting up to a year. It is a solid, honest option, and it works best combined with exercise.
