Cognitive behavioural interventions, and function and pain outcomes among patients with chronic neck pain managed...

Graded activity and graded exposure in vivo are recommended cognitive behavioural approaches to improve function and pain outcomes for patients receiving physiotherapy for chronic nonspecific neck pain. The McKenzie method is a common treatment approach for patients with neck pain. The study objectives were to examine associations between interventions with graded activity and/or graded exposure, as determined by the treating physiotherapist, and function and pain outcomes for patients with chronic nonspecific neck pain managed by clinicians with credentials in the McKenzie approach.

A cohort study was carried out, in which subjects (n = 366) with chronic nonspecific neck pain completed intake surveys (i.e., the Neck Functional Status Computerized Adaptive Test and the Numeric Pain Rating Scale), and questions related to their demographic, lifestyle and health status. Treatment with graded activity/graded exposure during the episode of care was recorded. Function and pain measures were repeated at discharge. Multivariable models examining associations between patients receiving versus not receiving graded activity/graded exposure, and pain and function outcomes were constructed, controlling for potential confounding effects.

Despite statistical significance, there were no clinically relevant differences between treatment versus no treatment with graded activity/graded exposure, and function or pain outcomes.

There is insufficient evidence to suggest that patients being managed with McKenzie methods will attain clinically relevant improvements in function or pain outcomes when augmenting treatment with graded activity and/or graded exposure when the choice to intervene with these cognitive behavioural approaches is determined by the treating physiotherapist.
