While not a standardized medical practice, gentle pressure four finger-widths above the anklebone can help induce labor in a woman ready to give birth, according to Giving Birth Naturally. Regardless of its efficacy, it's harmless and can be attempted with no risk.
Giving Birth Naturally details the procedure for pressure point manipulation of both the feet and hands to induce labor in a woman who is 41 or more weeks pregnant. The first spot is located four finger-widths above the ankle bone on the inside of both calves and requires firm, direct pressure in a circular motion, making the area feel slightly sore but not unduly painful. The practitioner stops applying pressure once a contraction begins and starts again once the contraction ends.
Giving Birth Naturally reports the second accupressure point is the webbing between the thumb and forefinger on both hands. The spot is massaged in a circular motion for 30 to 60 seconds, with a 1- to 2-minute break between contractions.
According to Giving Birth Naturally, this accupressure technique has no effect on inducing contractions or birth prematurely and only works when a baby is at full term and ready for birth. It's an effective and pleasant method of stimulating labor, the site says.
