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:
| Character | 0 | 1 | 2 |
| 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.
