From: Intensive vasodilatation in the sciatic pain area after dry needling
Average skin temperature changes of the sciatic leg (thigh, calf and foot) dependent on trigger points confirmation. Legend. The histograms reflected average temperature (Tavr) changes depending on TrPs presence for the thigh, calf and foot in the light of two phases (post-dry needling and post-observation). A statistically significant Tavr increase of TrPs-positive sciatica corresponding to vasodilatation (thigh, calf) contrary to Tavr decrease (calf, foot) and insignificant Tavr thigh increase of non-TrPs sciatica subjects was confirmed.
