Viscoelastic properties of cat tendon: Effects of time after death and preservation by freezing

摘要: Abstract In this study postmortem changes in the character of stress-strain limit cycle were analyzed for cat extensor communis and lateralis tendons maintained a stream Ringer's solution loaded with short series symmetrical triangular-wave stress cycles. The mechanical behavior these was compared that similar which had been preserved by freezing. It found overall stiffness (average apparent elastic modulus) did not change significantly first 3 hrs after death shape characteristics curves changed little under conditions. Tendons freezing displayed cyclessimilar to those fresh material. average moduli frozen lower than from degree statistically significant.
