The data presented in this graph represent the average tensile strength (± SEM) needed to induce a response in the hindlimb of rats pre-exposure toiSSC, and 2 and 10 days after injury. Two days after exposure to iSSCs, both the young and old rats showed an increase in sensitivity to mechanical stimulation (i.e., they responded to a fiber with a lower tensile strength). By day 10 sensitivity had returned to pre-exposure levels in young but not old rats (p <0.05; * < pre-exposure values and # < young rats).
