Validation and Test-Retest Reliability of New Thermographic Technique Called Thermovision Technique of Dry Needling for Gluteus Minimus Trigger Points in Sciatica Subjects and TrPs-Negative Healthy Volunteers

Figure 1

TTDN related thermograms presenting temperature reaction measured on skin surface of TrPs and non-TrPs sciatica patients and healthy volunteers. In rows: I: two cases of TrPs-negative sciatica, II: two cases of TrPs-positive sciatica, and III: two cases of healthy volunteers were shown. In rows Ia, IIa, and IIIa full thermogram was presented. In rows Ib, IIb, and IIIb the picture of the isothermal-area above called AURP was shown (visualization of the vasodilation). In columns: (a) Before TTDN (initial state), (b) state immediately after DN, and (c) state immediately after observation were presented.
