Currently there is insufficient evidence base for effective treatment for many OFP conditions resulting in multiple medical and surgical interventions failing on our patients rendering many with persistent pain. When a condition is termed idiopathic does that render that condition ‘refractory’ due to its non-responsive nature? ‘Refractory’ is a term loosely used in most of the orofacial pain literature. It is often used inter-changeably with persistent, resistant or intractable orofacial pain. What does the term refractory mean when applied chronic pain? The term ‘refractory pain’ is often used to refer patients for high risk and/or costly interventions otherwise unavailable to them. There are recent agreed criteria and definitions for resistant and refractory migraine and refractory Cluster headache. No other orofacial pain condition has these agreed published criteria for refractory pain. The insufficient evidence underpinning clear diagnostic criteria and proven treatments for many of the conditions we see also undermines the effective management of these conditions. In addition, we often fail to phenotype the patients pain sufficiently and or holistically endotype the patient, which thus undermining any clear relationship between supposed diagnosis and treatment outcomes. There may be many reasons for poor or non-response to treatment are many, however, the often over looked factors are; significant AXIS 2 issues, comorbid pain conditions, sleep disorders, medication overuse, medication sensitivity, lack of treatment compliance and using a multidisciplinary approach. Many patients also provide a diagnostic challenge due previous multiple medications and interventions masking the original pain phenotype. In future we may also look to assessing genetics and epigenetic and microbiome variants which will substantiate our patient endotype. By using a stratified holistic approach, we will optimise the patient’s pain management and provide the necessary evidence base for future improved care. However, there will always be some patients with pain that does not respond to conventional approaches, which we must acknowledge and define what other high risk and costly interventions may assist this group. and as a specialty we need to identify what approaches may benefit this group. Thus, there is a need for clearer definitions for Refractory states in Orofacial pain.

Jay P. Shah, MD is a physiatrist and clinical investigator in the Rehabilitation Medicine Department at the National Institutes of Health in Bethesda, Maryland. His interests include the pathophysiology of myofascial pain and the integration of physical medicine techniques with promising integrative approaches in the management of neuro-musculoskeletal pain and dysfunction. He also completed the UCLA Medical Acupuncture course and a two-year Bravewell Fellowship at the Arizona Center for Integrative Medicine.

Jay is a well-known lecturer on mechanisms of chronic pain, myofascial pain, acupuncture techniques and other related topics. He and his co-investigators have utilized novel microanalytical and ultrasound imaging techniques that have uncovered the unique biochemical milieu and viscoelastic properties of myofascial trigger points (MTrPs) and surrounding soft tissue. Their studies have demonstrated objective, reproducible and quantifiable muscle tissue properties associated with MTrPs and the quantitative effects of dry needling of active MTrPs on these tissue properties, in addition to showing significant improvements in pain, range of motion and patient self-report outcomes in mental health and physical function. Jay was selected by the American Academy of Pain Management as the 2010 recipient of the Janet Travell Clinical Pain Management Award for excellence in clinical care and by the National Association of Myofascial Trigger Point Therapists as the 2012 recipient of the David G. Simons Award for excellence in clinical research.

Dr. Quan is a Senior Physician in the Division of Sleep and Circadian Disorders at Brigham and Women’s Hospital and the McGinnis Professor of Sleep Medicine at Harvard Medical School. He was the founding editor of the Journal of Clinical Sleep Medicine and has served as the president of the American Academy of Sleep Medicine. His current research activities focus on the epidemiology of sleep and sleep disorders.

Dr. Janey Prodoehl is a Professor and Assistant Program Director in the Physical Therapy Program at Midwestern University Downers Grove, Illinois. She completed her entry level physical therapy degree in Leeds, England, an advanced Master of Science degree in physical therapy at Rosalind Franklin University, and doctoral and post-doctoral studies at the University of Illinois at Chicago. She has over 30 years of experience as a physical therapist primarily in out-patient orthopedic settings and was certified as an orthopedic clinical specialist by the American Board of Physical Therapy Specialties.

Her doctoral studies examined motor control in focal dystonia, and her post-doctoral work examined functional and structural neuroimaging in patients with movement problems. She sees patients in the Physical Therapy Institute at Midwestern University with a physical therapy practice focused on neck pain, orofacial pain, and headache, and dry needling for musculoskeletal dysfunction. Her research focus is to ask questions related to motor control that will lead to an improved understanding of musculoskeletal movement dysfunction, particularly as it relates to orofacial pain and postural dysfunction. Dr. Prodoehl has authored numerous publications from her work. She is a Certified Cervical & Temporomandibular Therapist by the Physical Therapy Board of Craniofacial & Cervical Therapeutics. She currently serves on the Board of Directors of the Illinois Physical Therapy Foundation.
