The Effect of Information on the Time Course of Pain During an Episode of Acute Experimentally Induced Low Back Pain-A Randomised Experiment.

ABSTRACT:

Background

We compared the time course of pain intensity ratings between two groups who were given different information during an episode of acute experimentally induced LBP.

Methods

Fifty weight-training naive and pain-free people participated in this randomised clinical experiment. Immediately after performing a back exercise intended to cause delayed onset muscle soreness, one group was told that their muscles had been damaged and advised they needed to protect their back over the coming days. The other group's symptoms were described in terms of tissue sensitisation, and they were advised to keep moving. The primary outcome was movement-evoked low back pain intensity measured using an 11-point numeric rating scale (NRS 0-10). Pain intensity was recorded at baseline, imm
