Treatment targets of exercise for persistent non-specific low back pain: a consensus study

Abstract

Objectives
Despite several hundred previous randomised controlled trials (RCTs), the key treatment targets of exercise for persistent non-specific low back pain (NSLBP) remain unclear. This study aimed to generate consensus about the key treatment targets of exercise interventions for patients with NSLBP.

Design
Consensus was generated using modified nominal group technique in two, sequential, workshops. The results of a previous systematic review informed the first, national, workshop idea generation and the results of this workshop informed the second, international, workshop. We generated a starting list of 30 treatment targets from the systematic review. A pre-specified consensus threshold of 75% was used in the voting stage.

Participants
Workshop participants included people with experience of using exercise to manage their persistent NSLBP, clinicians who prescribe exercise for persistent NSLBP, and researchers who design and evaluate exercise interventions in RCTs. All participants generated, voted and ranked the treatment targets in each workshop using an online platform.

Results
A total of 39 participants contributed to the consensus (15 in the national workshop and 24 in the international workshop), comprising two people with NSLBP, six clinicians and 31 researchers/ clinicians. A total of 40 exercise treatment targets were generated, and 25 were retained after voting and ranking. The prioritised targets of exercise for persistent NSLBP were: improving function, improving quality of life, reducing pain, meeting patient-specific goals and reducing fear of movement.

Conclusions
Future RCTs of exercise should specify the targets of their exercise intervention and consider assessing these treatment targets as well as including mediation analyses.
