Sensitivity of the SHR model parameters in (a) aging—solid lines represent mature, dashed lines represent aging, and dotted lines represents aged b mature group healing, c aging group healing, and d aged group healing. In (b)–(d), solid lines represent uninjured, dashed lines represent 3 weeks post-injury and dotted lines represents 6 weeks post-injury. $\mathit{\psi }$, the fascicle alignment angle was the most influential
