Results

95 and 116 had a vaginal delivery without and with epidural analgesia. The median number of steps increased daily in both groups, with no significant difference between the groups. Postpartum pain was mild overall, with median pain scores <4 and similar between the groups. MFI and EQ-5D-5L scores were worst on postpartum (PP) day 1 and gradually improved to antenatal level by 1-month PP visit. The use of epidural analgesia was associated with lower odds of achieving adequate PP ambulation.

Baseline Characteristics

Primiparous women anticipating a vaginal childbirth between January 2020 and May 2021 were enrolled. Women with major comorbidities or postpartum complications and those who underwent a cesarean delivery were excluded.

Participant flow

Daily step count was measured using a wrist-worn activity tracker (FitbitTM Inspire HR) for 120 hours after vaginal childbirth. Subjective
fatigue levels and health-related quality of life were assessed using the Multidimensional Fatigue Inventory (MFI) and EuroQol 5 Dimension 5 Level (EQ-5D-5L), respectively, at the 3rd trimester antenatal visit, on postpartum day 1 and 3, and at the one-month postpartum visit. Rest and dynamic pain scores and the
