The influence of non-specific low back pain on pressure pain thresholds and disability

When the group of patients with LBP was divided into two subgroups in terms of having an Oswestry disability index (ODI) lower than 40 (“moderate LBP disability”) or an ODI higher than 40 (“severe LBP disability”) it was surprising to notice that there was no significant difference between the PPTs of the Erector spinae and the hip musculature. This study has shown the possibility of the existence of muscular disorder in the lumbar part of the Erector spinae in patients with non-specific low back pain, but also reveals the strong inter-individual differences in muscular fibrosis sensitivity and pain behaviour related to gender.
