Why are bony landmarks preferred to skin landmarks for measuring?
- They are always visible
- They are identical to the millimetre in everyone
- They hardly move with the skin or with body weight
- They need no palpation
Show the answer
They hardly move with the skin or with body weight
A measurement's repeatability depends on how stable the landmark is.
