Abstract

The nonlinear viscoelastic bahavior of the human vocal fold extracellular matrix (ECM) under uniaxial tensile loading was characterized. Vocal fold cover specimens were dissected from larynges excised postmortem from three subjects (97 year old female, 17 year old male, and 65 year old male). A sinusoidal uniaxial tensile stretch-release protocol similar to that of Alipour and Titze was conducted on each cover specimen, at a loading rate of 1-10Hz and at a pre-strain of ∼0-30%. It was found that μ A = 0.90 μ for the 97 year old female and the 17 year old male, and μ A = 0.99 μ for the 65 year old male.
