Normalized creep function curve of normal human sciatic nerve and amniotic membrane specimens.

The Y-axis represents the normalized creep function (zero dimension, greater than 1) and the X-axis represents time. The normalized creep function was calculated according to the formula of J(t)=L(t)/L(0), in which L(t) is the normalized creep function, L(0) is the length of specimen at 0 second, and L(t) is the length of specimen at a given time point. Data are expressed as mean ± SD, n = 15. The 7 200-second creep function value was greater in the amniotic membrane group compared with the sciatic nerve group (P < 0.05; paired t-test).
