Skills Training and Relief for Orofacial Pain

Chronic orofacial pain (COFP) is comprised of various disorders in the temporomandibular region causing pain that lasts more than three months and are associated with substantial physical and psychological burden. These disorders often co-occur with other conditions such as headache, general chronic pain, and psychiatric disorders. The etiology of COFP is complex, with environmental, psychosocial, emotional, and genetic factors contributing to the development, chronicity, and maintenance of these disorders. Regardless of etiology, COFPs are impactful, commonly resulting in interference with daily activities, reduced quality of life (QoL), and mental health difficulties. COFP disorders are therefore best treated with multidisciplinary approaches combining psychological interventions and comprehensive orofacial pain care. Numerous psychological interventions for chronic pain are available, drawing from numerous theoretical orientations. Cognitive behavioral therapy (CBT) is a goal focused intervention designed to teach patients skills in restructuring cognitive distortions and thought patterns while promoting self-efficacy, which have shown to reduce pain intensity and psychological distress. Many relaxation techniques use a self-management approach by encouraging patients' role in managing their condition by learning skills to implement within their daily routine. Carlson (2008) categorizes multiple methods of relaxation techniques ranging from brief, easily taught skills to structured therapist-led interventions. He categorizes multiple methods of relaxation techniques ranging from brief, easily taught skills (brief relaxation techniques) to structured therapist-led interventions such as Physical Self-Regulation, where a therapist trains the patient through breathing exercises, clenching awareness, postural relaxation, and postural reeducation (progressive relaxation training). Despite the multitude of empirically-supported psychological interventions available, they all share common obstacles; namely, that uptake of these interventions in COFP clinic is low due to lack of sufficient specialized orofacial pain treatment providers, financial resources, and mental health stigma, and patients not expecting to have clinical psychologists involved in their COFP management, which has historically been treated (with minimal success) by dental providers alone, among other obstacles. Additionally, while literature suggests the effectiveness of these interventions for COFP populations, patients are often met with access related issues. These treatments introduce barriers through financial costs associated with healthcare and travel, lack of geographic access, especially for patients in rural communities, and few professionally certified clinicians to provide services. Consequently, there is also a lack of multimodal tertiary clinics available that offer treatments combining dental, psychological, and behavioral healthcare, leading patients to travel far distances for interdisciplinary treatments that can last hours across multiple sessions. Geographic access also poses a significant issue because interdisciplinary COFP clinics are scarce, with many states not having any access to specialty care, despite their being empirical evidence for greater longitudinal outcomes in COFP patients. Recent literature has identified Empowered Relief (ER), a virtual single-session, two-hour group-based intervention developed at Stanford University that overcomes many of the existing obstacles. ER introduces evidenced-based skills through a single session, two-hour course where patients develop tools that allow them to become self-sufficient in managing their chronic pain. The session can be held through a virtual format, providing accessible care and reducing patient travel or long stays. The training also provides space for multiple patients to receive care at one time as ER is hosted in a group format, allowing more patients to receive treatment over time. The effectiveness of ER was first demonstrated through a pilot study that included participants with various chronic pain conditions which indicated significant reduction in distress and improved participants' ability to use self-regulation strategies for pain management 4 weeks post intervention. Additionally, a randomized control study found that one session of ER was just as effective as eight weeks of traditional CBT for reducing pain catastrophizing and pain intensity in individuals with chronic lower back pain. Currently, no literature to date has investigated the feasibility and acceptability of ER in patients with COFP, indicating a gap in literature. The present study aims to fill this gap to work towards the identification of a low-cost and low-burden intervention for this underserved population.
