Post-laceration parameter percentage of pre-laceration values for (a) nominal stress parameters, (b) MRA stress parameters, (c) stiffness, and (d) specified load parameters. (a) Nominal stress percentages decrease for both cyclic and relaxation parameters. (b) MRA stress parameters begin to increase at 2.0 mm laceration. (c) Stiffness decreases with increasing laceration size. (d) Strain and MRA stress increase post-laceration. Error bars represent standard error (n = 8) and differing Greek letters (α, β, γ) represent significant differences between laceration groups within each parameter determined by the Fisher's least significant difference post hoc analysis (p < 0.05).
