UC in adenomyosis patients according to VAS score of dysmenorrhoea during Menses UC feature Direction of UC feature Reported VAS Score (n) Pvalue* 2 (n=1) 5 (n=1) 6 (n=2) 8 (n=5) 9 (n=1) 10 (n=1) CF (contraction s/minute) AW in radial direction 1.25 1.28 1.10 (0.25) 1.24 (0.18) 1.07 1.04 0.401 PW in radial direction 1.83 1.30 1.41 (0.15) 1.20 (0.24) 1.07 1.07 0.012 Amplitude (SD) AW in radial direction 0.040 0.032 0.039 (0.015) 0.056 (0.01) 0.050 0.061 0.027 PW in radial direction 0.040 0.044 0.034 (0.009) 0.040 (0.01) 0.040 0.065 0.305 Velocity (mm/s) F2C propagation, AW 0.90 0.61 0.90 (0.40) 0.64 (0.11) 0.63 0.49 0.109 C2F propagation, AW 0.76 1.05 0.82 (0.06) 0.70 (0.14) 0.72 0.55 0.112 F2C propagation, PW 0.90 0.50 0.78 (0.22) 0.78 (0.24) 0.79 0.40 0.493 C2F propagation, PW 1.25 0.75 0.69 (0.01) 0.79 (0.20) 0.68 0.38 0.028 Coordination (MSE) 0.28 0.07 0.17 (0.08) 0.20 (0.06) 0.13 0.49 0.469 All data are presented as mean (SD). *p-value was considered significant at <0.05. The association between the UC features and dysmenorrhea (VAS score) in the adenomyosis group during M phase was measured using the Pearson correlation coefficient. VAS: visual analogue scale; UC: uterine contractions; CF: contraction frequency; AW: anterior wall; PW: posterior wall; F2C; fundus-to-cervix; C2F: cervix-to-fundus Mid-follicular phase UC features of adenomyosis patients were compared to those of healthy controls during the MF phase of the menstrual cycle (see Table 8.4). The CF was statistically significantly lower in the adenomyosis group compared to the healthy controls in the PW (1.48±0.21 vs. 1.69±0.16, p=0.013). Contraction coordination was statistically significantly worse in the adenomyosis group compared to the healthy controls (0.30±0.09 vs. 0.20±0.08, p=0.019). No other UC features differed statistically significantly.
