Participants were instructed to document in the log the amount of pain during sports, 2 h after sports and the next morning (all using the VAS pain scale), as well as the duration (minutes) and intensity (0–100 mm VAS scale) of the athletic performance. It was also documented if the participants who used an orthosis in the intervention week experienced a difference in pain between the 2 weeks with the question: “Did you experience a decrease in pain wearing the orthosis during sports compared to control?” The answer options were yes and no. The participants in the control group did not have to answer this question.
