Figure 2. Interstitial glycerol concentrations in the stimulated subcutaneous area and the unstimulated control area in the contralateral leg in 7 healthy female subjects.

Glycerol concentrations were significantly higher in the stimulated subcutaneous area (○) from the start of measurement, in all probability due to the preceding neural search procedure and trial stimulations, and was further increased during 10 min of intraneural stimulation while no effect was seen in the control area of the contralateral leg (•). * P < 0.05.
