Pilot Study to Investigate Autonomic Function in Patients With Chronic Musculoskeletal Pain.
Pilot Study to Investigate Autonomic Function in Patients With Chronic Musculoskeletal Pain.
Previously it has been demonstrated that exposing the heart to electromagnetic field during exercise stress test improves the recovery following the stress test. This is explained by the effect of the electromagnetic field on the sympathetic activity of the heart. In the present study we would like to further investigate the effects of electromagnetic field on autonomic nervous system function in patients with chronic musculoskeletal pain that usually have high sympathetic activity. Each patient will be exposed to 20 minutes of electromagnetic field during which the autonomic nervous system function will be measured. In addition, patient tolerability to the exposed magnetic field will be investigated. We assume that short exposure to electromagnetic field would result in decreased sympathetic activity and therefore, on the long run, could be suggested as a therapeutic tool for such patients.
Adult patients suffering from chronic muscoloskeletal pain will be recruited to this study during their weekly visits to the Department for Complementary Medicine at Sheba Medical Center. Patient will be exposed to 20 minutes of weak intensity and low frequency electromagnetic field while seated, during which heart rate variability measures will be recorded. In addition, patient tolerability to the exposed electromagnetic field will be investigated, including VAS score (pain score). This is a double blind placebo-control study by which neither the patients nor the physicians know which treatment is given to the patients. The study code will be open only at the end of the trial.
