Figure 2From: Quantitative pinch stimulator for exploring evoked nociceptive responses: A pilot study Specifications of the pinch stimulator. (A) This photograph shows how the strain gauge attaches to the forceps (Dumont, type 2A). (B) Shown is the frequency response. (C) The transfer function of the stimulator, i.e., the relationship between the output voltage and the force produced by the forceps, is shown.Back to article page
