421 effects of slow repetitive transcranial magnetic stimulation (tms) on complex regional pain...
TRANSCRIPT
ing students, 10 physician assistant students and twopharmacy students.
Results. Pre-course assessment demonstrated that ineach of the programs, with the exception of pharmacy,pain education received little attention, including less than2 h within medical education. Post-course assessmentindicated satisfaction with the course, as well as the aimsof an interdisciplinary approach to pain education.
Conclusion. Goals of this project include the compila-tion of a curriculum, including teaching materials, pow-erpoints, and other tools to assist in the implementationof similar programs at other institutions.

421EFFECTS OF SLOW REPETITIVE TRANSCRA-
NIAL MAGNETIC STIMULATION (TMS) ON
COMPLEX REGIONAL PAIN SYNDROME (CRPS)

Background. The key symptom of CRPS is continu-ous, intense pain out of proportion to the injury. Redskin, increased temperature, sweating and swelling arecommon. These symptoms suggest an inflammatoryprocess. One theory is that an auto-immune process trig-gers the immune response. A single 20-min session ofprefrontal repetitive TMS can alleviate pain, as shownby a 40% reduction in total morphine use after gastricbypass surgery. A similar single session applied to themotor cortex can decrease the pain of CRPS, asreported by seven of 10 patients.
Aims. The aims of this study are to: (1) replicate thefinding that one session of TMS provides temporaryrelief from CRPS pain; (2) determine if 10 sessions pro-vide more lasting relief and (3) determine if molecularmarkers support the theory that CRPS is an inflamma-tory process.
Methods. Ten participants will receive 10 real and 10sham TMS treatments; five will start with real, and fivewith sham. Patients will rate the intensity of pain on avisual analogue scale. C-reactive protein and lipopro-tein-associated phosholipase A2 (known molecularinflammatory markers) will be measured at baseline,after sham TMS and after real TMS.
Results and conclusions. This study is not yet com-plete; results and conclusions will be added to theabstract by March 31, 2007.

422PULSED RADIOFREQUENCY TREATMENT (PRF)

Introduction. The Pasha Cath is a multifunctionalcatheter used for diagnostic and therapeutic aims.The catheter is placed exactly on the wished nervousroot, using the fluoroscopic images, the impedance val-ues and sensory stimulation a 50 Hz current. This cur-rent evokes paraesthesias on the metameric arearelated.
At this point it can proceed to the selective infusion ofdrugs and/or PRF.
Objective. To evaluate the analgesic effectiveness ofPRF treatment in periferic neuropathic pain.
Design. Prospective, open-label, nonrandomized trial.Setting. Department of Pain Medicine, Private Hos-
pital, Italy.Inclusion criteria. All patients affected by lumbar
radiculopathy for more than six months, with pathoge-netic diagnosis of periferic neuropathic pain.
Interventions. In all patients it has been used a PRFtreatment for 240 s using Pasha Cath, on the target root,through sensory neurostimulation.
Effectiveness assessments. NRS at rest and incident,Oswestry test, QUID test (Italian Pain Questionary) atbaseline, first and third month.
Results: Follow-up in progress.

Introduction. The Pasha Cath is a multifunctionalcatheter used for diagnostic and therapeutic aims. Thecatheter is placed exactly on the wished nervous root,using the fluoroscopic images, the impedance valuesand a sensory stimulation of a 50 Hz current. This cur-rent evokes paraesthesias on the metameric area related.
At this point we can proceed to the selective infusionof drugs and/or PRF.
