Arms of the Study
Arm 1
Experimental
Impedance spectroscopy
24 women will be included in the study and divided into two subgroups. 12 of them (first subgroup) came from patients within 6 to 8 weeks after natural delivery, that had a perianal tear of grade 1 or 2 in OASIS classification. Remaining 12 (second subgroup) came from patients within 6 to 8 weeks after natural delivery, that had a perianal tear of grade 3 or 4 in OASIS classification. The planned interventions are: Blood and faeces tests Impedance spectroscopy test Full gynecological and proctological examination Transanal ultrasonography Anorectal manometry
