Percent maximum force production recovery among treatment groups 14 days after I/R injury. Maximum tetanic force production (P0) of the LGAS was measured in situ from the following groups: PEGylated fibrin (PEG-Fib), PEGylated fibrin conjugated to SDF-1α (PEG-Fib/SDF-1), and PEGylated fibrin conjugated to SDF-1α and IGF-I (PEG-Fib/SDF-1α/IGF-I). The P0 were compared to the contralateral leg that received no injury. Values expressed as mean ± SEM, one-way ANOVA, Tukey post-hoc: *p < 0.05 versus PEG-Fib, n = 6.
