A Study on the Reliability of Sasang Constitutional Body Trunk Measurement

Table 1

A comprehensive training for sasang constitutional body trunk measurement.

Training contentDescription

5-width measurement and training

Observer postureAn observer measures a subject with locating his face in subject’s midline.
Subject respirationA subject maintains stable respiration and measurement is conducted between inspiration and expiration.
Maintenance of horizontal orientation of measuring instrumentsMeasuring instrument should be located in the same point of the lateral body.
Measuring intensity of measuring instrumentApplied pressure should not distort skin or other human tissue during the measurement.
Measuring method
Interaxillary widthA subject with attention posture everts left and right arms from the trunk for 5 degrees. An observer places fixed end of the large caliper on the right starting point of subject’s axilla. He places movable end of the caliper on the left starting point of subject’s axilla and measures the distance between two starting points.
Chest widthA subject with attention posture everts left and right arms from the trunk for 5 degrees. An maginary line is drawn from the right starting point of subject’s axilla to lateral corner of the right anterior superior iliac spine (ASIS). This line is superimposed over the line connecting right and left nipples. Fixed end of the caliper is placed on the intersection point of the two lines. Movable end of the caliper is placed on the point contralateral to the intersection point in the left side. Horizontal distance between these two points is measured.
Rib widthA subject with attention posture everts left and right arms from the trunk for 5 degrees. An imaginary line connecting subject’s right axillary starting point and distal corner of the right ASIS. Another line connecting right and left 7th and 8th prominence of costochondral junction is drawn. Fixed end of the caliper is placed on the intersection point of the two lines. Movable end of the caliper is placed on the point contralateral to the intersection point in the left side using observer’s right hand. Horizontal distance between these two points is measured.
Waist widthA subject with attention posture everts left and right arms from the trunk for 5 degrees. An imaginary line connecting subject’s right axillary starting point and distal corner of the right ASIS. Another line connecting right and left Tianshu (ST25) is drawn. Fixed end of the caliper is placed on the intersection point of the two lines. Movable end of the caliper is placed on the point contralateral to the intersection point in the left side using observer’s right hand. Horizontal distance between these two points is measured.
Pelvic widthFixed end of the caliper is placed on the lateral part of subject’s right ASIS and movable end of the caliper is placed on the distal of subject’s left ASIS. Horizontal distance between these two points is measured.

8-circumference measurement and training

Observer postureAn observer measures in front of a subject.
Subject respirationA subject maintains stable respiration and measurement is conducted between inspiration and expiration.
Maintenance of horizontal orientation of measuring instrumentsA measuring instrument is placed parallel with observer’s hand, eye, and location of the measurement (exception: the shortest distance is measured for the neck circumference).
Measuring intensity of measuring instrumentApplied pressure should not distort skin or other human tissue during the measurement (exception: forehead circumference is measured with finger pressure firmly on subject’s hair).
Measuring method 
Forehead circumferenceA subject sits up on the chair with his back straightened. An observer holds the “0 point” with one hand. He wraps the tapeline around subject’s forehead passing the glabella and the opisthion and overlaps the tapeline and measures. The observer should apply sufficient pressure on subject’s hair.
Neck circumferenceA subject sits on the chair with his back straightened. He maintains his forehead position parallel to the floor. An observer stands in front of the subject and wraps the measuring tape around the neck passing the area between the thyroid cartilage and the cricoid cartilage. The shortest distance is recorded.
Axillary circumferenceA subject undresses upper body and stands up straight with balanced pressure on the right and left feet. An observer stands in front of the subject. The subject raises his arms laterally and the observer wraps measuring tape around the subject’s upper body to pass the right and left axilla and midpoint of the chuhndohl (CV22) and the joongjuhng (CV16). The subject lowers their arms in a natural way and the circumference is recorded.
Chest circumferenceA subject undresses upper body and stands up straight with balanced pressure on the right and left feet. An observer stands in front of the subject. The subject raises his arms laterally and the observer wraps measuring tape around the subject’s upper body to pass the right and left nipple point. The subject lowers their arms in a natural way and the circumference is recorded.
Rib circumferenceA subject undresses upper body and stands up straight with balanced pressure on the right and left feet. An observer stands in front of the subject. The subject raises his arms laterally and the observer wraps measuring tape around the subject’s upper body to pass the right and left 7th and 8th prominence of costochondral junction. The subject lowers their arms in a natural way and the circumference is recorded.
Waist circumferenceA subject undresses upper body and stands up straight with balanced pressure on the right and left feet. An observer stands in front of the subject. The subject raises his arms laterally and the observer wraps measuring tape around the subject’s upper body to pass the umbilical cord. The subject lowers their arms in a natural way and the circumference is recorded.
Pelvic circumferenceA subject undresses upper body and sufficiently rolls down the pants and underwear to expose measuring areas. He stands up straight with balanced pressure on the right and left feet. The subject crosses his arms on the chest. An observer stands in front of the subject wraps the measuring tape to pass the right and left ASIS. The circumference is recorded.
Hip circumferenceA subject undresses upper body and sufficiently rolls down the pants and underwear to expose measuring areas. He stands up straight with balanced pressure on the right and left feet. The subject crosses his arms on the chest. An observer stands in front of the subject wraps the measuring tape to pass right over the pubis. The circumference is recorded.
