Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Quantitative Sensory Testing (QST, DFNS protocol), conditioned pain modulation (CPM) and skin temperature measurement in the affected area and contralateral were examined at first with inactivated stimulation and then with activated stimulation. QST investigates the function of thick-, thinly- and unmyelinated nerve fibers (A-ß, A-d and C nerve fibers). CPM evaluates the efficacy of diffuse noxious inhibitory controls (DNIC). Temperature measurement is an established indirect technique to detect sympathetic blockade, shown through an increase of skin temperature. | — |
