Non-Specific Low Back Pain Lasting 6–12 Weeks in Adults Aged 18 and Over

Clinical scenario

This protocol applies to adults aged 18 and over with non-specific low back pain that has persisted for 6 to 12 weeks — the subacute phase, in which symptoms have outlasted a typical acute episode but have not yet crossed into the chronic range. No specific structural cause underlies the pain.

Relevant guidelines

Multiple international clinical practice guidelines focusing on the management of non-specific low back pain in adult populations (18 years or over) inform this protocol. These guidelines treat the subacute window — pain lasting less than 12 weeks — as a distinct phase requiring targeted recommendations.

Treatment approach — partial overview

Structured management at this stage involves oral analgesic therapy alongside continued therapeutic exercise and encouragement to stay active. The full clinical pathway, including the complete intervention sequence and decision criteria, is set out in the protocol.

CPGs focusing on information regarding the management and/or treatment of non-specific LBP were considered eligible.

The CPG concerned adult populations (18 years or over).

Eight of the guidelines characterised acute and subacute LBP as having a duration of less than 12 weeks but without specific cutoff points to distinguish between the two.

Further recommendations about other drugs like paracetamol, opioids, muscle relaxants and antidepressants vary considerably.
