Summary

Use these resources to provide understandable information about this study to patients, families, and health care providers: The present randomized clinical trial (RCT), conducted at the IRCCS Carlo Besta Neurological Institute, aims to evaluate the effectiveness of Pain Reprocessing Therapy (PRT), a form of psychological support/psychotherapy based on cognitive-behavioral therapy, which has already proven effective in the treatment of other types of primary chronic pain. Chronic Primary Orofacial Pain (CPOP) is a rare and complex form of chronic pain that predominantly affects adult women and occurs without evident lesions, yet has a significant emotional and functional impact. It was recently classified among chronic primary pain conditions in the ICD-11 and is considered a form of nociplastic pain, associated with alterations in brain connectivity. At present, pharmacological treatments have shown limited effectiveness. This randomized clinical trial (RCT), conducted at the IRCCS Carlo Besta Neurological Institute, aims to evaluate the effectiveness of Pain Reprocessing Therapy (PRT), a form of psychological support/psychotherapy based on cognitive-behavioral therapy, which has already proven effective in the treatment of other types of primary chronic pain. Sixty participants, all diagnosed with CPOP according to ICD-11 criteria, will be selected and randomly assigned to two groups: one will receive PRT, the other will receive treatment as usual (TAU). The primary outcome of the study is the assessment of pain intensity reduction. Secondary outcomes include a broad range of psychosocial variables: improvement in quality of life, reduction of anxiety-depressive symptoms, catastrophizing, and other psychopathological traits. The effects of the therapy on brain connectivity will also be analyzed using fMRI, and on pain neurophysiology through the Conditioned Pain Modulation (CPM) paradigm. The protocol provides for the evaluation of therapy effectiveness at three follow-ups (3, 6, and 12 months) in order to measure the duration of effects. Finally, through advanced statistical analysis tools and the support of artificial intelligence, the study also aims to identify specific clinical-neurofunctional profiles that may be useful for differential diagnosis and for tailoring therapeutic interventions.

Conditions

• Chronic Primary Orofacial Pain (CPOP)
• Persistent Idiopathic Facial Pain (PIFP)

Interventions

Type	Name	Description
BEHAVIORAL	Pain Reprocessing Therapy	One cohort of 30 patients (PRT+TAU group) will receive eight sessions of Pain Reprocessing Therapy (PRT) in addition to Treatment-as-Usual (TAU). PRT is a cognitive-behavioral-inspired approach aimed at helping patients reinterpret chronic pain as brain-generated rather than structurally caused. A second cohort of 30 patients (TAU group) will undergo the same assessment phases but will receive only Treatment-as-Usual without PRT. Use this module to add a description of each group or cohort in the study and to list any interventions of interest.
BEHAVIORAL	Usual Therapy	Patients undergo yhe usual pharmacological tretment as prescrived by neurologist
