  1. Rehabilitation for the Sensitized Nervous System: What Can PT and OT do for the pain patient? Nora Stern, PT, MSPT

  2. Conflict of Interest DisclosureNora Stern, PT, MS, PT Has no real or apparent conflicts of interest to report.

  3. Looking at what is sensitizing the systems: • Nociceptive input • Peripheral • Central • Output driven

  4. Nocioceptive • Active inflammatory process: • Treatment: Explain Pain Address fear avoidance Motion is lotion: flushing inflammation

  5. Peripheral neurogenic presentation • Follows nerve pathway or adjacent pathway, but in new areas along pathway • Shooting up or down along pathway

  6. Treatment for peripheral neurogenic • Motion is lotion • Address neurodynamics • Health of container: taping, manual therapy • Decrease in threat value: pain education, normalize experience • What does pt need to hear?

  7. Assessing central sensitization • Pain searing, stabbing, like a knife, hot poker • Diffuse • Appearing on other side of body, pain in new area • Not consistent w findings • Does not follow anatomy • Large or diffuse areas of pain • Black body diagram • Altered 2 point discrimination • Delay in laterality recognition > 1.5 sec, < 90% accuracy

  8. Central: Beliefs about painStarT Generic Screening Tool

  9. Assessing sensory cortical reorganization: • Two point discrimination testing

  10. Assessing central involvement: cortical reorganization: Smudging Altered Two Point Discrimination Associated with Distorted Body Image in Back Pain Fig. 1 Patient data: TPD threshold, normal distribution of pain, and body image. Two-point discrimination threshold (TPD) was assessed bilaterally at 16 levels, shown here superimposed over line drawings of the sense of physical self, or body image, of six... Moseley, GL, “I Cant’ find it! Distorted body image and tactile dysfunction in patients with chronic back pain.” Pain Vol 140, Issue 1, 2008, 239-243

  11. Central: what aspects of the brain processing are contributing to central sensitization? • Thinking • Feeling • Sensing • Acting/moving

  12. Disruption of output, mirror neurons and sensory and motor homuncular representation (smudging) • Swelling • Sweating • Itching • cold sensitivity • Pain w thinking about movement, watching someone move • Altered 2 point discrimination • Altered body schema • Poor motor planning

  13. Treatment interventions:Central • Pain education: • Fear Avoidance and Graded Exposure: Moseley and Butler’s twin peaks

  14. Treatment Interventions: Central • Cortical Reorganization: • Graded Motor Imagery • Body scan • General kinesthetic sensing with exercise • Whole body movement to restore virtual body representation

  15. Graded Motor Imagery • Laterality recognition: • Activates pre-motor but not primary motor cortex Norm of 90% accuracy and 1.5 sec reaction time • Imagined movement • Mirrors

  16. Graded exposure • Pacing: twin peaks • Vary the task: • Laterality recognition • Imagine movement • Change setting • Do in pleasurable context • Do parts of a task; eg knees to chest as component of bending over

  17. Treatment Interventions:Central • Stress response: physiological quieting • www.meditationcenter.com: easy to follow meditations. • http://www.allaboutdepression.com/relax/ 8 free breathing tapes, relaxation activities. • http://vcc.asu.edu/relaxaindex.shtml: free guided instruction in progressive muscle relaxation and guided imagery.
