Chronic Low Back Pain: Physiotherapy vs. CBT, What New Research Shows

If your low back has been sore for months, you have probably heard plenty of advice. Stretch more. Rest more. Strengthen your core. Manage your stress. It can be hard to know where to start. A large study published in 2026 put two common options head to head for chronic low back pain: physiotherapy and cognitive behavioural therapy (CBT). This guide from Lake Country Physiotherapy in Orillia explains what the researchers found, what chronic low back pain physiotherapy looks like, and what the results mean if you are living with a back that will not settle.

What Is Chronic Low Back Pain?

Low back pain is called chronic when it lasts longer than about three months. That is different from a sudden strain that eases within a few weeks (you can read more in our post on acute pain vs. chronic pain). Low back pain is one of the leading causes of disability around the world, and in most people no single damaged structure can be pinned down as the cause (Foster et al., 2018).

Because there is rarely one simple fix, guidelines recommend starting with non-drug treatments. The American College of Physicians advises that people with chronic low back pain begin with options such as exercise, multidisciplinary rehabilitation, mindfulness-based stress reduction, CBT, and spinal manipulation before turning to medication (Qaseem et al., 2017). The open question has been which of these to try first.

About the Study: Physiotherapy vs. CBT

The trial, led by Dr. Julie Fritz and published in the Annals of Internal Medicine, was designed to answer two practical questions: which treatment works better as a first step, and what should happen next if the first step does not work (Fritz et al., 2026). Here is how it was set up:

  • 749 adults with chronic low back pain took part, across three health care systems in the United States.
  • Each person was randomly assigned to eight weeks of either physical therapy (physiotherapy) or CBT.
  • People who had not improved by at least half on a disability questionnaire were then randomly assigned to a second eight-week stage: either mindfulness training or switching to the other treatment.
  • Everyone was followed for a full year, with check-ins at 10, 26, and 52 weeks.

Unlike many programs that blend everything together, this study offered the treatments one after the other. That made it possible to compare them directly.

How Did They Measure Improvement?

The researchers tracked two main outcomes. The first was function, measured with the Oswestry Disability Index (ODI). This is a 0 to 100 questionnaire that asks how much back pain gets in the way of everyday tasks like sitting, walking, sleeping, lifting, and getting out of the house. Lower scores are better. The second was pain intensity on a 0 to 10 scale.

What Did the Research Find?

  • Physiotherapy came out ahead on function. After 10 weeks, the physiotherapy group had improved more on the ODI than the CBT group, by an average of 2.8 points.
  • The gap was modest. A change of about 6 points is usually seen as the smallest difference a person would notice, so the extra benefit from physiotherapy was real but small.
  • Pain improved by a similar amount in both groups. There was no meaningful difference in pain intensity at 10 weeks.
  • For people who did not respond at first, the next step mattered less than expected. After a year, people who moved on to mindfulness did about as well as people who switched treatments, for both function and pain.

The authors concluded that people with chronic low back pain may benefit from physiotherapy as a first-line treatment (Fritz et al., 2026).

Keep the Limitations in Mind

No single study is the final word. Fewer people started their assigned treatment than the researchers expected, especially in the CBT group and in the second stage. Participants knew which treatment they were getting, and the COVID-19 pandemic reduced the number of people who could be enrolled (Fritz et al., 2026).

What This Means for You

Here are our main takeaways for anyone dealing with a stubborn back:

  • Physiotherapy is a sensible place to start. It was slightly better for getting people back to their daily activities, and it is backed by clinical guidelines.
  • Your mind and your back are connected. CBT helped pain just as much. Stress, sleep, worry about movement, and mood can all affect how much your back hurts, which is why good physiotherapy also covers education and confidence, not only exercises.
  • Not improving right away is not a dead end. If the first approach does not help enough, adding something like mindfulness or trying a different approach are both reasonable next steps.
  • Active care matters. Both treatments in the study asked people to take part in their own recovery rather than simply receiving treatment.

What Chronic Low Back Pain Physiotherapy Looks Like

Every back is different, so your plan should be built around you. At your first visit, a physiotherapist will usually:

  • ask about your history, your daily routine, and what you want to get back to
  • check how you move, along with your strength, flexibility, and any nerve symptoms
  • explain what is likely going on in plain language, so movement feels less scary
  • start a therapeutic exercise program that builds up gradually
  • use hands-on care such as manual therapy or joint mobilization when it helps you move more comfortably
  • help you pace activity so you can do more without big flare-ups

When to Get Help Right Away

Most chronic back pain is not dangerous. Seek urgent medical care if back pain comes with any of the following:

  • loss of bladder or bowel control, or numbness in the groin or inner thighs
  • weakness in one or both legs that is getting worse
  • fever, or feeling unwell along with back pain
  • unexplained weight loss or a history of cancer

Frequently Asked Questions

Do I need a doctor’s referral to see a physiotherapist in Ontario?

No. Physiotherapists in Ontario are direct access providers, so you can book without a referral. Some insurance plans ask for one before they will pay, so check your coverage.

How long does physiotherapy for chronic low back pain take?

In this study, the first stage of treatment lasted eight weeks. Your own timeline depends on how long you have had pain, your goals, and how you respond. We will review your progress regularly and adjust the plan.

Does this mean CBT does not work for back pain?

No. CBT reduced pain about as well as physiotherapy, and it remains a recommended option. The study suggests physiotherapy is a slightly better first step for function, not that other approaches lack value.
