We are currently undertaking an epidemiological study establishing the prevalence of patellofemoral pain in European adults between the ages of 18 and 40, using a self-report SNAPPS questionnaire (Survey instrument for Natural history, Aetiology and Prevalence of Patellofemoral pain Studies).
As of right now, we have initiated the translation and the cultural validation of the SNAPPS questionnaire into Finnish and Turkish. Also, we have begun the early stages of migrating the questionnaire into a digital version.
