Height measurement
Standing height is measured using a free standing stadiometer. When measuring a person's standing height, the guidelines re as follows;
1) The sample stands straight with the head facing forward and shoulders relaxed
2) Arms are hang loosely at the sides with the palms facing forward to
3) Feet are placed together and knees straightened
4) Heels, buttocks and shoulder blades of the sample should touch the vertical backboard of the stadiometer.
5) The sample is barefoot without wearing any socks.
6) Make sure that the Frankfurt plane is horizontal.
7) During measurement, the subject takes a deep breath and stands still
8) Measurements are recorded to the nearest millimeter.
9) The time of measurement is recorded.
Knee height A knee height caliper (Fig. 3.2) is used to measure the knee height of a person. Both right and left knees are measured. In cases where both legs cannot be measured due to cast, amputation or sores, only one leg is measured. During measurements, the following are recommended:
1) The sample sits on a chair with knee on a 90 degree angle.
2) The fixed caliper is positioned under the heel of the foot while the movable caliper is positioned on the anterior surface of the thigh above the femoral condyles and proximal to the patella.
3) Measurements are recorded to the nearest 0.1 centimeter.
4) Both left and right knee height measurements are performed.
5) Measurements are repeated in cases when the results differ by greater than 0.4 centimeter.
