Multidimensional Analysis of the Clinical Spectrum and Symptom Burden of Unexplained Myofascial Pain.

This was a single measurement in time, so it cannot say which factor came first or whether changing one changes another. The authors state their results do not imply causal links between the physical and psychosocial components. Everyone fell into one of three groups classified by myofascial examination, and the 'normal' comparison group was not truly pain-free: 41% reported no current pain, but many still had trigger points and symptom burden, which limits how the comparisons should be read. Records were incomplete for 14 of the 96 recruited participants, and there were more women in the active group. Only 82 people were analysed and the active group was small for the network analysis. The authors say the network stability was only moderate and that the findings need confirming in a larger sample. The analyses were exploratory with no adjustment for testing many comparisons at once, so the authors say the p-values are a guide rather than a firm level of significance. Eligibility criteria were deliberately broad, and several results come from subgroup analyses of the three groups rather than from the sample as a whole.

Do not read this as evidence that treating catastrophizing, mood, sleep, hypermobility or physical function will reduce neck and shoulder pain. Everyone was measured at a single point in time, so the study cannot show which factor came first or whether changing one changes the others, and the authors say their results do not imply causal links.
