title: The dynamic mechanical response characteristics of spinal cord tissue: a preliminary report.
abstract: In the absence of an adequate description of the response of spinal cord to dynamic insult, work is in hand to determine the dynamic characteristics of canine spinal cord tissue. In-vitro experimentation is described. A vibration technique using a low amplitude (0.5 mm), variable frequency (1--40 Hz) forcing frequency is used to describe the resonant property of the tissue in a supporting environment. The canine spinal cord is demonstrated to respond as a non-linear, soft, viscoelastic element suceptible in the frequency range 14--22 Hz.
