Subject position:The subject assumes a relaxed standing position with the left arm hanging by the side.The subject's right arm is slightly flexed at the shoulder,the elbow is extended,the forearm supinated and the hand relaxed.
This girth measurement is taken distal to the styloid processes.It is the minimum girth in this region.Manipulation of the tape measure is required to be sure the minimal girth is obtained.The tissues should not be compressed by excessive tension.
Subject position:The subject assumes a relaxed standing position with the arms hanging by the sides and slightly abducted.
This girth is taken at the level of the mesosternale.The anthropometrist stands to the right of the subject who abducts the arms to the horizontal position allowing the tape to be passed around the thorax.The stub of the tape and the housing are then both held in the right hand while the anthropometrist uses the left hand to adjust the level of the tape at the back to the adjudged level of the marked mesosternale.
The anthropometrist resumes control of the stub with the left hand and using the cross-hand technique positions the tape in front at the level of the marked mesosternale.
The subject is instructed to lower their arms to the relaxed position with the arms slightly abducted.The tape is then readjusted as necessary to ensure it has not slipped and does not excessively indent the skin.The subject should breathe normally and the measurement is taken at the end of a normal expiration.
