Proportional change in vibration sensation by mode of delivery. Proportional change = 3 or 6 months postnatal perception threshold/ antenatal perception threshold. Yellow line at 1.0 represents no change from antenatal baseline, if value < 1.0 sensation improved compared to antenatal baseline, if value > 1.0 sensation deteriorated. Kruskal Wallis group-wise comparison shown below boxes and significant Dunns post-hoc pairwise comparisons above boxes. Two outliers excluded. Index finger missing data (n = 4) at antenatal with corresponding missing proportional change data. CS caesarean section, NVD normal vaginal delivery, AVD assisted vaginal delivery.
