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 cervix||Posterior||Axial||Anterior|
|Dilatation of cervix||0cm||1cm||>2cm|
|Length of cervix||2cm||1cm||<0.5cm|
|Consistency of cervix||Firm||Soft||Soft and stretchable|
|Station of head||-2||-1||0|
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.
