Transvaginal Photobiomodulation Improves Pain in Women with Pelvic Muscle Tenderness and Interstitial Cystitis/Bladder Pain Syndrome: A Preliminary Observational Study.

PURPOSE: Interstitial Cystitis/ Bladder Pain Syndrome (IC/BPS) is characterized by pelvic/bladder pain, associated with pelvic muscle tenderness, urgency, frequency, and dysuria. Prior studies show that transvaginal photobiomodulation (TV-PBM) reduces pain in women with chronic pelvic pain (CPP). Our objective was to obtain preliminary data on treatment effect and adherence, in women with IC/BPS who selected TV-PBM therapy for management of pelvic pain. MATERIALS AND METHODS: Before-and-after observational cohort study of women with IC/BPS who received TV-PBM in 17 US practices. Pain was measured using a 0-10 numeric rating scale (NRS). The primary outcome was a minimal clinical important difference (MCID); reduction of overall pelvic pain severity by ≥2 NRS points from baseline compared to after 8 treatments. Cohen d coefficient measured effect size (low effect size d<0.2, medium 0.20.8). RESULTS: Of 140 patients with IC/BPS who self-selected to start TV-PBM therapy, 89.3% (n=125) completed 4 treatments and 59.3% (n=83) completed 8. Improvement ≥1 NRS point was reported by 73.5% (n=61) and meaningful improvement (≥2 points) was reported by 63.9% (n=53) after 8 treatments. In this group, patients with severe / moderate pain decreased from 83.1% (n=44) to 38.5% (n=20); p<0.001. Pain levels decreased as follows: overall pelvic pain MCID=-2.7, d=1.07, pain with urination MCID=-2.6, d=1.0; pain with exercise MCID=-2.6, d=0.91, pain with intercourse MCID=-2.5, d=0.82. CONCLUSION: In real-world clinical settings, 2/3 women with IC/BPS who opted to undergo TV-PBM therapy reported significant decrease in pelvic pain and dysuria. These findings are promising; however, controlled studies are needed.

Transdermal posterior tibial nerve laser therapy is not effective in women with interstitial cystitis.

PURPOSE: Interstitial cystitis (IC) is a debilitating condition which causes irritative bladder symptoms, pain and a decrease in health status. The pathophysiology is poorly understood so therapeutic options are diverse. Percutaneous posterior tibial nerve stimulation is an effective treatment and pulsed transdermal laser stimulation is an established technique for pain management. We evaluated the efficacy of transdermal laser stimulation of the posterior tibial nerve for patients with IC. MATERIALS AND METHODS: Women meeting the National Institutes of Health National Institute for Diabetes and Digestive and Kidney Diseases criteria for IC were prospectively recruited and randomized to treatment (29) or placebo (27) cohorts in a double-blind trial. At home the patient performed laser therapy daily for 30 seconds over the SP6 acupuncture point for 12 weeks. Measures at baseline and at 84-day followup included the 7-day voiding diary, the Interstitial Cystitis Problem Index, Interstitial Cystitis Symptom Index and RAND 36-Item Health Survey questionnaires. RESULTS: There were no significant differences between the treatment and control cohorts on any of the measures. However, there was a significant decrease between baseline and 12-week followup in the amount voided, symptom problems and severity, and on all 8 SF-36 scales. There was no significant effect of fluid intake. CONCLUSIONS: This study demonstrated no difference between the active and sham device. However, it is interesting that treatment and control cohorts experienced similar improvements, suggesting that the control cohort improvements may have been due to participants' belief that they were receiving active treatment from the stimulator. These findings provide support for investigating placebo effects in randomized trials.

Multiple modality therapy of interstitial cystitis (IC)--the disease characterized by nicturia, pelvic pains, imperative pollakiuria--is considered. As IC nature is not well known, its treatment remains empiric. Among the underlying causes, most probable are autoimmune, allergic, infectious, neurological, vascular. Therefore, the treatment should be multi-modality. Most usable now is combined chemotherapy. Perspective is also IC treatment with medicines in combination with physiotherapy (electromagnetolaser AELTIS-SYNCHRO-02-YARILO"). Endovesical electrophoresis can be also applied.
