Mohammad, T., and A. R. Youssef, "Time to recovery of sciatic function index after induced tibialis anterior strain in rats.", Muscles, ligaments and tendons journal, vol. 7, issue 3, pp. 576-582, 2017 Jul-Sep. Abstract

Background: Muscle strain is a common injury with a high recurrence rate. Due to the heterogeneity of strain injuries, experimental animals provide controlled and reproducible models to investigate such injuries. Sciatic Function Index (SFI) is a clinically feasible method to assess hind limb recovery in rodents after induced injuries.

Objectives: To investigate time to recovery of SFI after induced-strain in tibialis anterior (TA) muscle in rats.

Methods: Sixteen adult male Wister rats were randomly and equally divided to a normal control group that received no intervention, and TA induced muscle strain group. Muscle strain was induced using an external weight that corresponded to 150% of the animal body weight. SFI was tested only once in the control group. For the muscle strain group, SFI was tested on the 1, 2, 3, 4, 7, 11, 20 and 24 days after strain induction.

Results: Comparisons between group showed significant difference in SFI on the 1, 2, 3 and 4 days (p= 0.012, 0.012, 0.012 and 0.028, respectively).

Conclusions: In a rat animal model of TA induced muscle strain, functional recovery measured by SFI is evident on the 7 day post-injury, which corresponds to the sub-acute phase of injury.
