Study procedures
Physical therapists screened patients for eligibility at their first consultation. After providing informed consent, eligible patients were included and asked to complete questionnaires on clinical outcomes and costs at baseline (T0), 3-month follow-up (T3), 6-month follow-up (T6), and 12-month follow-up (T12), in addition to a questionnaire at 9-month follow-up (T9) for costs only, to avoid recall bias.
