Skin Resistivity Value of Upper Trapezius Latent Trigger Points

Figure 1

Example of TrPs, control (TrPs-negative), and norm electrodes localization during SkR measurement. The black electrodes show TrPs localization (x1 and x2) and, on the opposite site, next two black electrodes TrPs negative x1 and x2 localization. The electrodes with the letter “B” show “reference points,” and the three white electrodes on each side refer to the norm (not tender points of the surrounding tissue).
