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