Effect of one session of tDCS on the severity of pain in women with chronic pelvic pain.

AIM: The present study aimed to investigate the effects of tDCS on pain score in women with Chronic Pelvic Pain (CPP). MATERIALS & METHODS: A total of 16 women with CPP participated in the present double-blind sham-controlled cross-over study. Each participant received a 20-min 0.3 MA of trans Cranial Direct Stimulation (tDCS) with a current density of 0.1 mA/cm2. In addition to the pain intensity, the Quality of Life (QOL), disability, and depression statuses were assessed prior to and one week after the treatment. Shapiro-Wilks goodness-of-fit test for normality, dependent t-Test, and Wilcoxon Signed- Rank Test were used for data analysis. Values of p < .05 were considered statistically significant. FINDINGS: Active tDCS treatment was effective in the reduction of pain (p = .0001), improving QOL (208.938 > 193.313, P = .025), and the disability (22.375 < 30.375, P = .025). The results showed no effect of active or sham treatment on the depression (p ≥ .05). CONCLUSION: The positive effects of active tDCS on CPP suggest the need to study the effect of this method on other types of chronic pain.

Pelvic musculoskeletal dysfunctions in women with and without chronic pelvic pain.

AIM: This study aimed to compare the prevalence of pelvic musculoskeletal dysfunctions in women with and without Chronic Pelvic Pain (CPP). MATERIALS &METHODS: A total of 84 women with and without CPP (42 in each group), participated in this cross-sectional analytical study. After collecting demographic information, clinical examinations were carried out to compare pelvic musculoskeletal dysfunctions between two groups. Kolmogorov-Smirnov (K-S) goodness-of-fit, Independent t, X2 and Pearson correlation tests were used for data analysis. Values of p < 0.05 were considered statistically significant. FINDINGS: Significant differences were found in the asymmetric iliac crest and pubic symphysis height (45.2% vs 9.5%), positive sacroiliac provocation and positive Carnett's tests (50% vs 4.8%), (p < 0.05). CPP Patients exhibited more tenderness at Levator ani, Piriformis, and Obturator Internus muscles, also higher degrees of pelvic inclination (p < 0.05). CONCLUSION: Higher frequency of pelvic musculoskeletal dysfunctions in women with CPP suggests the value of routine musculoskeletal examinations for earlier diagnosis of musculoskeletal originated CPP and effective management of these patients.
