These authors conclude that the idea that some back pain patients respond better to some treatments is probably still mostly hype.

Most low back pain has no known cause and is therefore considered “non-specific,” and there’s a wide range of response to treatment in these patients. A common assumption is that they actually have specific causes for their pain, even though we can’t identify them — but there is a hope that we can identify the patients who respond to specific treatments. This is the hope or hype about “subgrouping”: you don’t necessary have to understand how their pain works to identify types of patients that will respond better to treatment. There is a large, enthusiastic movement in back pain research to achieve this.

In this paper, in which the authors thoroughly “have deliberately chosen to argue 2 extreme positions,” both for and against the investigation of subgroups. Key points in favour:

And key points against:

They conclude: “the current research initiatives and achievements in this field are far from optimal and not yet ready to be implemented in clinical practice.”

Clinicians and clinical researchers share a common goal of achieving better outcomes for patients with low back pain (LBP). For that, randomized controlled trials and systematic reviews are the most reliable study designs to determine the effects of interventions. Subgroup analyses in these research designs have been used to examine treatment-effect modification across subgroups defined by patient characteristics. In this Viewpoint, the authors present supporting and opposing arguments for the subgrouping approach in nonspecific LBP, considering the progress made so far in the LBP field and the relevant literature in adjacent fields.
