Compliance effects in a randomised controlled trial of yoga for chronic low back pain: a methodological study.

ABSTRACT:

Study design

Methodological study nested within a multicentre randomised controlled trial (RCT) of yoga plus usual general practitioner (GP) care vs usual GP care for chronic low back pain.

Objective

To explore the treatment effects of non-compliance using three approaches in an RCT evaluating yoga for low back pain.

Summary of background data

A large multicentre RCT using intention-to-treat (ITT) analysis found that participants with chronic low back pain who were offered a 12-week progressive programme of yoga plus usual GP care had better back function than those offered usual GP care alone. However, ITT analysis can underestimate the effect of treatment in those who comply with treatment. As such, the data were analysed using other approaches to assess the problem
