Preliminary evidence for the features of non-reducible discogenic low back pain: Survey of an international physiotherapy expert panel with the Delphi technique

Abstract

Objectives: The lumbar intervertebral disc is a known source of low back pain (LBP). Various clinical features of discogenic pain have been proposed, but none have been validated. Several subgroups of discogenic pain have been hypothesised, with non-reducible discogenic pain (NRDP) proposed as a relevant clinical subgroup. The objectives of this study were to obtain consensus from an expert panel on the features of discogenic low back pain, the existence of subgroups of discogenic LBP, particularly NRDP, and the associated features of NRDP. Design: Three-round Delphi survey. Participants: Twenty-one international physiotherapists with expertise in LBP. Methods: Panellists listed and ranked f..
