Protocol schedule. The BPI (Brief Pain Inventory) and the HAD (Hospital Anxiety and Depression scale) were assessed before the start (D0) and after the end (D22) of the therapeutic protocol. The protocol consisted of 4 therapeutic sessions (S1–S4), each lasting 30 minutes and spaced 7 days apart (D1–D7, D7–D14, and D14–D21). The Numeric Pain Rating Scale (NS) was collected just before and just after each session.
