Self-administered questionnaire of US/British origin, the objective of which is to measure the functional impact of lumbago in order to determine its natural progression.
This scale was established from the Sickness Impact Profile (SIP) and the specificity for lumbago has been improved by adding the wording "because of your back".
The time taken is short, about 5 minutes.
It consists of 24 items concerning daily life activities graded from 0 to 1 point. The addition of the scores enables an assessment from 0 to 24.
There are numerous variables with a reduction of items: RDQ-23, RDQ-18, RDQ-16, RDQ-12, one version "twice": RDQ (two) to measure the variation at the end of 4 weeks, the RDQ7p in which a Liekert scale 7 points is added [8].
