Optimal parameters for studying referred pain using pressure stimulation – An explorative study

Takeaway

  • Pressure intensity at the pressure pain threshold (PPT) value +30% may be ideal for exploring the mechanisms of referred pain in a non-invasive manner.

Why this matters ?

    Studying of referred pain is often induced by injecting of hypotonic saline stimulation. Pressure stimulation offers a non-invasive approach to studying referred pain, but the optimal parameters have yet to be established.
