The physiotherapists were asked to fill in the following information:
The CDQ-24, a CD-specific assessment of quality of life with a special focus on CD-related problems in daily living [17 (link)], was obtained as a patient self-rating. It consists of 24 single items within five domains: stigma (question 7, 8, 9, 10, 18 and 22); emotional well-being (question 11, 12, 13, 14 and 15); pain (question 4, 5 and 21); activities of daily living (question 1, 2, 3, 6, 19 and 20) and social/family life (question 16, 17, 23 and 24). Each item ranks between 0 and 4 points, a higher score means a higher disease severity. The maximum score is 100 points, with 0 being the best and 100 being the worst possible CD-related Quality of Life [18 (link)].
We collected the rating of the TWSTRS severity score [19 ] and the details on the last BoNT treatment from the electronic medical records. The following BoNT preparations were used: OnabotulinumtoxinA (Botox®, Allergan, AbbVie company, Ireland), AbobotulinumtoxinA (Dysport®, Ipsen Pharma, France) and IncobotulinumtoxinA (Xeomin®, Merz Pharmaceuticals, Germany). To ensure comparability of the applied BoNT preparations, we used the following formula to calculate the equivalent dose for AbobotulinumtoxinA: 1 U OnaA or IncoA = 2.5 U AboA. This ratio showed similar efficacy and side effects according to a systematic literature review [20 (link)]. The TWSTRS was assessed in an unblinded manner prior to the injection of BoNT during the patients’ visit to our BoNT outpatient clinic.
