The intervention is a visceral abdominal self-massage.\n\nBecause individuals tend to respond differently to physiotherapy methods, the investigators aim to assess the effect of performing the self-massage regularly on the self-reported perception of menstrual pain and related symptoms of female students in Germany, with a series of N-of-1 trials.\n\nN-of-1 trials lasting up to 60 days are conducted with participants who regularly experience dysmenorrhea. Participants undergo a control (A) and an intervention phase (B), with a probable second control phase (A) depending on the individual cycle lengths and study start. Daily symptoms are recorded via the StudyU smartphone application. The baseline questionnaire collects demographic, lifestyle, and menstrual history information to identify potential effect modifiers. The intervention's effects will be estimated across individual and population levels.
