Surface electromyography diagnostics in women with partial vaginismus with or without vulvar vestibulitis and in asymptomatic women.
The aim of this study was to investigate to what extent women with superficial dyspareunia can be diagnosed for both partial vaginismus (PaV) and vulvar vestibulitis (VVS) and to discover to what extent surface electromyography (sEMG) of the pelvic floor muscles (PFM) can distinguish between women with PaV solely, PaV+ VVS, and asymptomatic women. A total of 224 consecutive women with superficial dyspareunia were examined clinically for both PaV and VVS diagnoses. We examined 47 women with PaV+/-VVS and 27 asymptomatic women with sEMG of the PFM. The results showed that 102/224 women with superficial dyspareunia and 33/47 women with PaV in the sEMG part of the study had both PaV and VVS. All women with VVS had vaginismus, while 42/224 had PaV but not VVS. sEMG measurements revealed no significant differences between the three groups of women (PaV solely, PaV + VVS, and asymptomatic). Almost half of the women with superficial dyspareunia referred to our clinic have both the diagnosis PaV and VVS. sEMG was not a method of any value to distinguish between women with PaV solely, PaV + VVS, or asymptomatic women. The increased tone found clinically in the PFM of women with PaV+/-VVS may be of other origin than electrogenic contractions.
