The Color of Itch; Itch Modification by Color Viewing
An observational study of Itch and Pruritus, run by University Hospital, Basel, Switzerland at 1 site in Switzerland.
Trial summary
Itch is the commonest skin-related symptom. There is increasing evidence that itch can be influenced by visual cues. The impact of colors on itch has not yet been studied. This study investigates Itch modification by color viewing and whether patients can match or counteract their itch with a color. Read more about this study

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
exploratory survey on Itch modification by color viewingOther
Patients relate their itch to a color of the Manchester Color Wheel (MCW) and choose a color of the MCW aimed at counteracting their itch. They complete the ItchyQoL (German version), which is a standard tool to assess itch-related quality of life. Then patients look at their "antipruritic" monochrome color for five minutes on a lap-top screen. Itch intensity (0-10 NRS) will be assessed at baseline and again after the patients looked at this color for 5 minutes.
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in itch intensity
Change in itch intensity (measured on a 0-10 Numerical Rating Scale, NRS); 0 = no itch; 10 = most intensive itch
Measured: assessed at baseline and again after the patients looked at the "antipruritic" color for 5 minutes

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in itch intensity (time frame: assessed at baseline and again after the patients looked at the "antipruritic" color for 5 minutes). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
