Aim of the study is to determine heat pain thresholds (HPT in °C) and cold pain thresholds
(CPT in °C) during topical capsaicin 8% application, and mechanical pain thresholds (MPT in
g) immediately after to find out the exact skin temperature by which capsaicin initiates the
application pain (heat pain threshold, HPT in °C) but also the temperature by which capsaicin
does not yet trigger a cold pain (cold pain threshold, CPT in °C). Moreover the investigators
want to find out the mechanical pain threshold in g from topical capsaicin and to verify a
prolonged effect of capsaicin on the pain thresholds.
