Effects of Rhythmic Sensory Stimulation on Ehlers-Danlos Syndrome: A Pilot Study.

Ehlers-Danlos syndrome (EDS) is a connective tissue disorder characterized by joint hypermobility and skin extensibility and is often accompanied by chronic pain. Rhythmic sensory stimulation (RSS) can be defined as the stimulation of the senses in a periodic manner within a range of low frequencies. Music plus sound delivered through a vibroacoustic device is a form of RSS and has demonstrated utility in managing pain. In this current study, we conducted an open-label pilot study of 15 patients with hypermobile EDS using RSS as the intervention. Posttreatment improvements were seen in 11 of the 15 patients (73%), whereas 3 of the 15 patients (20%) experienced worse outcomes. Of the 14 patients that completed the experiment, 6 participants (43%) were classified as "responders" to the device while 8 participants (57%) were classified as "nonresponders." Responders demonstrated significant improvements in pain interference (51.5 ± 16 preintervention vs. 43.5 ± 16.4 postintervention BPI score) and depression symptoms (34.0 ± 15.9 preintervention vs. 26.8 ± 12.1 postintervention CESD score). Poststudy interviews confirm the improvements of pain interference, mood, and bowel symptoms. Furthermore, analysis of medical conditions within the responder group indicates that the presence of depression, anxiety, irritable bowel syndrome, and fibromyalgia may indicate a greater likelihood for patients to benefit with vibroacoustic applications. These results indicate a possible potential for RSS, delivered using a vibroacoustic device, in managing pain-related symptoms. Further research is necessary to elucidate the exact mechanism behind the physiological benefits of RSS.

A parallel randomized controlled trial examining the effects of rhythmic sensory stimulation on fibromyalgia symptoms.

This double-blind, two-arm parallel randomized controlled trial investigated the effects of gamma-frequency rhythmic sensory stimulation on fibromyalgia. We were interested in whether rhythmic sensory stimulation would promote significant changes in fibromyalgia and associated symptoms, and whether treatment effects would differ between two distinct treatment parameters. Fifty patients with a formal diagnosis of fibromyalgia were randomly assigned to two test groups. One group received vibrotactile stimulation from a continuous sine wave single-frequency stimulation (40 Hz) for 30 minutes, five days per week, over five weeks, concomitant with usual care. The second group completed the same treatment protocol but received a different stimulation, consisting of random and intermittent complex wave gamma-range vibrotactile stimulation. Fibromyalgia symptoms, pain severity and interference, depression symptoms, quality of life and sleep quality were assessed at baseline and post-intervention. Results indicated that there were statistically significant changes from baseline to post-treatment in measures of fibromyalgia symptom severity, pain interference, depression, and sleep quality. However, treatment outcomes did not differ significantly between groups. These findings provide preliminary evidence that gamma-frequency rhythmic vibroacoustic stimulation may decrease fibromyalgia symptoms and ease associated comorbidities, opening new avenues for further investigation of the effects of rhythmic sensory stimulation on chronic pain conditions.

Development, implementation and evaluation of a pain management and palliative care educational seminar for medical students.

BACKGROUND: Despite calls for the development and evaluation of pain education programs during early medical student training, little research has been dedicated to this initiative. OBJECTIVES: To develop a pain management and palliative care seminar for medical students during their surgical clerkship and evaluate its impact on knowledge over time. METHODS: A multidisciplinary team of palliative care and pain experts worked collaboratively and developed the seminar over one year. Teaching methods included didactic and case-based instruction, as well as small and large group discussions. A total of 292 medical students attended a seminar during their third- or fourth-year surgical rotation. A 10-item test on knowledge regarding pain and palliative care topics was administered before the seminar, immediately following the seminar and up to one year following the seminar. Ninety-five percent (n=277) of students completed the post-test and 31% (n=90) completed the follow-up test. RESULTS: The mean pretest, post-test and one-year follow-up test scores were 51%, 75% and 73%, respectively. Mean test scores at post-test and follow-up were significantly higher than pretest scores (all P<0.001). No significant difference was observed in mean test scores between follow-up and post-test (P=0.559), indicating that students retained knowledge gained from the seminar. CONCLUSIONS: A high-quality educational seminar using interactive and case-based instruction can enhance students' knowledge of pain management and palliative care. These findings highlight the feasibility of developing and implementing pain education material for medical students during their training.

Evaluation of the frequency and the association of sexual pain and chronic headaches.

BACKGROUND: Sexual pain and chronic headaches are both complex conditions with associated high disability. Little research has examined whether there is a relationship between the 2. The aim of this survey-based study was to explore the frequency of sexual pain in a population of women being treated for chronic headache. Peripheral aims included exploring the number of patients receiving treatment for sexual pain and the association between sexual pain and libido, and history of abuse. METHODS: Patients presenting to an ambulatory chronic headache clinic were administered a short 10-item survey. RESULTS: Forty-four percent of patients reported that they had pelvic region or genital pain brought on by sexual activity. Only half of these patients had ever discussed their pelvic pain with a health care provider, and 31% of these patients had not received treatment. Almost all patients would be interested in treatment if available. Seventy-five percent of patients indicated a change in libido. CONCLUSION: Chronic headaches and sexual pain are both conditions that have a significant impact on patients and the health care system, and they do coexist. More research is needed to look at the relationship between these conditions in addition to epidemiology, symptomatology, evaluation, and treatments.
