This two-day course introduces information critical to the assessment and treatment of patients with acute, sub-acute and chronic pain. Utilizing pain science research regarding pain mechanisms this course teaches pain clinicians how to classify and treat pain as it relates to the peripheral and central nervous system. A Pain Mechanism Classification System (PMCS) will be introduced and then guide the selection of patient education and active care interventions for each pain mechanism. The PMCS demonstrated through live patient demonstrations when available, video and paper case studies will aid application to pain clinicians practice. This course highlights a subgrouping method, PMCS, which addresses pain throughout the continuum from acute, subacute and chronic stages covering chemical, structural, mechanical, cognitive, emotional, social, psychological and cortical mechanisms. This course integrates pain science research into a biopsychosocial approach with practical application for patient education and active care interventions. Promoting a common language between pain clinicians of all disciplines and patients. Included in this course, the application of peripheral nervous system neurodynamic evaluation, treatment, and central nervous system sensory and motor evaluation, patient-rated outcome measures and psychometric tools outlined by the dominant pain mechanism. The PMCS patient education and active care interventions support all patient ages and musculoskeletal to neurological diagnoses suffering from pain.
