Labour Ball Positioning in Labour

Elevate the upper leg as far away from the lower leg as possible to increase the transverse diameter of the pelvic outlet.

Encourage your patient to curl forward creating a C-shape of the spine. This aligns the uterus with the pelvis and the baby’s presenting part with the pelvic inlet. Try to keep the patient upright to create an angle between the patient’s spine and the uterus. The contractions will then direct the baby toward the larger posterior half of the pelvic inlet where there is more room for the baby to flex, rotate and descend.

Ensure the sacrum and coccyx are free to move back, thereby increasing the anterior-posterior diameter of the pelvis.

Sizing Recommendations

• 40cm – Recommended for women who are under 5’ 3”
• 50cm – Recommended for women who are 5’3“ to 5’6” (Most common size)
• 60cm – Recommended for women who are 5’7” or taller or obese women
• 70cm – ONLY to sit on and straddle

Keep your patient moving. Change positions every 30 min.

Movement and position change promote labour progress.
