Modified Bishop's Score

Modified Bishop’s Score is a criterion that can be used as a prognostic index for the success of induction. It takes into consideration factors such as condition of cervix and station of presenting part. It is calculated as follows:

Position of cervixPosteriorAxialAnterior
Dilatation of cervix0cm1cm>2cm
Length of cervix2cm1cm<0.5cm
Consistency of cervixFirmSoftSoft and stretchable
Station of head-2-10

Total score is calculated by adding the individual scores. A value more than 6 indicated that the cervix is favourable for induction (high probability for vaginal delivery). Values less than 3 indicates that caesarian section may be required.
