Dry Needling Related Short-Term Vasodilation in Chronic Sciatica under Infrared Thermovision
Visualization of short-term vasodilation (the area of vasodilation higher than of the initial state). In order to describe the area of short-term vasodilation using IRT procedure, patient temperature reaction was isolated—grey pictures column. In rows, cases one and two (TrPs-positive) and three and four (non-TrPs) were shown. In column (a) pre-DN (initial) state, in column (b) vasomotor referred pain after DN (phase II), and in column (c) the vasomotor referred pain after observation (phase III) were presented.
