Point Location
When you draw an imaginary line between the bony prominence of the neck (C7), and the top of the shoulder joint (the acromion process), this point lies midway along this curved line, at the highest point of the shoulder muscle. It will feel tender with a numbing/ buzzing/ warming sensation (this sensation varies with individuals). The sensation is stronger on this point than any other points along this line You can find this point on yourself by bringing your hand diagonally across your chest and palpating with your index finger along this "imaginary line."
Acupressure Technique
It is important that support people apply firm downwards pressure with their thumb/ knuckle/ elbow. This acupressure point responds to pressure, massaging and rubbing the area can be irritating for women during labour.
When using the thumbs the pressure needs to come from the arms rather than the thumb joint - otherwise people will end up with very sore thumbs.
It is not unusual for support people to resort to using the ends of two wooden spoons, but it is preferable to start with using hands when possible. These acupressure points are usually used with the support person applying pressure using their knuckles on both shoulders together, but I know of women who have successfully used this on themselves using only one shoulder at a time.
The pressure can be applied at the beginning of each contraction or continual gentle pressure applied that is intensified during contractions.
This acupressure point has a descending action to aide the first and second stages of labour and can stimulate uterine contractions.
This acupressure point is to be used with caution during pregnancy
