Growing Pains: Are they Due to Increased Growth During Recumbency as
Documented in the Lamb Model? ", J. Pediatric Orthopedics, Vol. 24, No.6,
Nov/Dec 2004
The notion that children grow taller while they sleep is probably true, US
researchers say. They put MicroStrain wireless DVRT sensors into the leg
bones of baby lambs and confirmed that most growth spurts occurred when the
animals were at rest or sleeping. The sensors, mounted directly to bone,
transmitted linear displacement data from a fully implantable, hermetically
sealed, battery powered module. This was the first time that direct
measurements of growth plate displacements were made in living bone. Their
results showed that rapid periods of bone growth occur when the animals were
lying down. When the animals were standing or walking, the sensors measured
oscillatory displacements, as the growth plate compressed and then recoiled
during gait.
