How big is the effect of spinal manipulation on the pressure pain threshold and for how long does it last? - secondary analysis of data from a systematic review.

ABSTRACT:

Background

Spinal manipulation (SM) has been shown in a systematic review to have a statistically significant effect on the pressure pain threshold (PPT) in asymptomatic subjects, when SM is compared to a sham intervention. The magnitude and duration of this effect is unclear.

Objectives

To determine the effect-size of SM in asymptomatic subjects and its duration.

Method

This is a secondary analysis of data from a previous review. We sought to compare the effect-sizes in the various articles but had to calculate them ourselves, at different follow-up time measurements. Effect-sizes (Cohen's d or Hedge's g coefficient) were considered low, medium, and large, at the cut points of 0.2, 0.5, and 0.8, respectively.

Results

Effect-sizes were reported in 6/8 studies,
