Multicenter Trial Assessing an Innovative VAS of Pain Among Deaf People

Assessment of an Innovative Visual Analogue Scale of Pain (Pictorial VAS) Versus the Usual VAS (VAS) Among Deaf People

The purpose of this study is to assess an innovative Visual Analogue Scale of pain (pictorial VAS) versus the usual VAS (VAS) among Deaf People.

The assumption of this study is that pictorial VAS is more suited to Deaf people than usual VAS.

Indeed French literature showed that 80% of Deaf people are illiterate. Moreover, lip-reading only allows to recognize one third of words.

Pictorial VAS includes elements which promote understanding of Deaf people: colours and 6 detailed expressive faces.
