Spring 2014

  • Landmarking necessary for repeatability of measures
  • Only a few landmarks are required for the measures used in this course

Landmarks must be

short horizontal lines

Standard Landmarking & Measurement Position

stretch stature height
Stretch Stature (Height)
  • Head held in Frankfort Plane
  • Requires two people to measure
  • Feet together
  • Stretch justified as overcoming diurnal variation
  • Check for heel lifting (especially in children)
variability of height
Variability of Height
  • Height can vary up to 2.5cm a day or more
  • Compression of the intervertebral discs occurs
  • Lost height can be restored with fetal curls
  • Fluctuation
  • Calibrated scale
  • Beam balances tend to hold calibration longer
  • OMRON Scale and Body Composition Analyzer
  • Parallel fold of double thickness of skin plus subcutaneous adipose tissue
  • Caliper applied perpendicular to the fold
  • Fold held firmly by left hand while full pressure is applied by caliper
  • 2 second timing until reading
  • Skinfolds can be measured at any site where there is a loose junction between subcutaneous adipose tissue and the underlying fascia.

Skinfold Descriptions


the caliper distance when applied one centimeter distally from the left thumb and index finger raising a fold beneath the inferior angle of the scapula in a direction running obliquely downwards at an angle determined by the natural lines of tension in the skin. The pick up can be made consistent by placing the little finger of the left hand on the angle of the scapula then placing the index finger just to the right of it and the thumb just below it.


  • Circumference perpendicular to the long axis of the body segment
  • Tape should be touching but not indenting skin
  • Cross-handed technique
projected heights
Projected Heights
  • Perpendicular distance from floor to landmark
  • Tibiale Height usually measured standing although sometimes used seated for disabled populations.
  • Derived length = difference between two projected heights
direct lengths
Direct Lengths
  • From landmark to landmark
bone widths breadths
Bone Widths & Breadths
  • Caliper type and placement specific to measurement
  • Press firmly while measurement is made
  • Vernier Scale

measurement reliability
Measurement Reliability
  • How do you quantify reliability?
  • Is a correlation coefficient adequate?
  • Technical Error of Measurement?
correlation coefficient poor indicator of reliability
Correlation Coefficient: Poor indicator of reliability
  • A high correlation between trials does not necessarily indicate reliability unless slope is 1 and intercept is 0.
  • Means of trials 1 and 2 would be different. Paired t-test with no sig. diff. between means with a high correlation would show high reliability. But this would be clumsy analysis.

r = > 0.9

Technical Error of Measurement

Measure of variability between two trials

  • To compare the relative reliabilities of measures using different units such as height and weight, a %TEM is used.
  • %TEM is the absolute TEM divided by the mean of the measurements multiplied by 100.
  • A dimensionless score that can be compared across measurements.
  • Also for same measurement when size is an issue
