Uterine contractions: intensity, frequency, efficiency.
Women’s preferences
One consistent finding across studies: none report higher degree of comfort in the supine position.Not statedThe included trials are of variable quality and include different outcome measures. Hence the low EL grading and the inability to pool data.

Apgar scores (1 and 5 min)
Fetal heart rate: More women in ambulant group had fetal heart rate accelerations (10 vs. 1, p<0.01) and fewer decelerations 4 vs. 17, p<0.005)

First stage of labour significantly shorter (4.1 vs. 6.7 hours, p<0.001)

Contractions were less frequent in the ambulant group (8.53 vs. 10.13 in 30 min, p<0.05) but stronger (55.53 vs. 46.54 mmHg, p<0.005)
Significantly more ambulant women used no analgesia during labour (20 vs. 0, p<0.001)
The overall dose of pethidine administered to ambulant women was signif. lower (103 vs. 153 mg, p<0.001)
Apgar scores were significantly better for babies born to women in the ambulant group (1 min: 8.8 vs. 7.5, p<0.001; 5 min: 9.9 vs. 9.4, p<0.05

Maternal comfort (as measured by observer)
Women in upright group had signif. shorter active phase of labour (mean difference 90.25 minutes, p=0.003).
