Onderzoeksopzet
Measuring instrument is a diary used by the subject to record the experienced itch, pain and disability on a 100mm Visual analoge scale (one for each item) on a daily basis. Exposure to cold is registered daily using records of the Royal Netherlands Meteorological Institute (KNMI). There will be 6 face to face contacts: Intake (t1), end of week 1 (t2), end of week 4 (t3), end of week 7 (t4), end of week 10 (t5) and end of week 13 (t6).
Primary and secondary outcomes are evaluated using data before and after intervention or placebo treatment (using data from t2, t4 and t6).
Statistical analyses wil be performed using the repeated measures mixed effects model and with regard to possible temperature change during the rechearch period.
