What the New Acute Low Back Pain Guideline Recommends

Who wrote it and who it is for

The guideline was developed for the American Academy of Pain Medicine with the Pacific Northwest Evidence-based Practice Center at Oregon Health & Science University.¹ It covers adults seen in outpatient care for low back pain of less than six weeks, with or without pain travelling down the leg. Recommendations were graded with the GRADE system, which separates strong recommendations from conditional ones.

1. Most people do not need a scan

For most episodes of acute back pain, no single structure can be identified as the cause. The guideline makes a strong recommendation against routine imaging when there are no warning signs of a serious problem.^1,2 Scans become useful when there are red flags, or when pain is not settling or is getting worse after about four to six weeks.

2. Staying active is the starting point

Understanding the usual course of back pain, and knowing that gentle activity will not cause harm, is the foundation of care. Lighter daily activity is encouraged over bed rest.²

3. What it says about medication

Medication is outside a chiropractor's scope of practice in Ontario, so talk to your family doctor or pharmacist before starting anything. For reference, the guideline's main points are:²

• Heat and non-prescription anti-inflammatories (NSAIDs), used briefly, are options for people who can take them safely.
• Acetaminophen is not recommended for routine use, because a large placebo-controlled trial found it did not help. It remains a fallback for people who cannot take NSAIDs.
• Opioids are not recommended as a first treatment. A short course may be considered for severe, disabling pain when other options cannot be used.
• The panel found no support for antidepressants or gabapentinoids for acute low back pain.

4. If it is not improving after a week or two

If pain has not eased, or is worse, after one to two weeks, the guideline suggests adding at least one more treatment, such as physical therapy, acupuncture or a muscle relaxant.² Muscle relaxants are prescription medications, so discuss them with your doctor. Hands-on care and exercise can be part of that plan. It is one option among several, not something everyone needs, and the evidence specific to the first six weeks is thinner than many people assume.

The honest caveats

• This is a brand-new guideline. At the time of writing the full text was behind a paywall, so this summary is based on the published abstract and public reporting of the recommendations.
• Some recommendations are conditional, meaning the evidence is limited and the right choice can depend on the person.
• A guideline describes what tends to help groups of people. Your own plan should still be based on your history and exam.

Take-home

• Scans usually are not needed early on. Warning signs change that, not pain intensity alone.
• Keep moving within your limits.
• If you want to try medication, ask your doctor or pharmacist which options are safe for you. Opioids are not a starting point.
• If you are not improving after a week or two, add another treatment rather than waiting it out alone.
