- Comparisons are made between the Trapezius myalgia (TM) and a healthy control group without pain with respect to pain/exercise provocation. The following acronyms are used: before pain provocation (bpp), after pain provocation (app), Max = maximum value, RMS = Root mean square value, Diff = Difference between the value before, and after pain provocation (result is given in absolute value). The results of the statistical analyses between the two groups are given at the far right. The result shows no significant differences on groups level
