ABSTRACT
AIMS:
Platelet-Rich Fibrin (PRF) is a new and promising technique for tissue repair, however, there is still a gap about its action on peripheral nerve injury, as well as its association with physical exercise. Thus, the aim of this study was to evaluate the effects of the PRF associated with physical exercise in a model of median nerve compression.METHODS:
42 rats, divided into Control, non-injured limb, and other six groups with nerve lesion (Control lesion; Treated with PRF; Treadmill walking; Free swimming; PRF and treadmill; PRF and swimming). The lesion model was performed with median nerve compression. To obtain the PRF, 1.5 mL of blood was centrifuged and the fibrin clot positioned directly over the compression region. The exercise protocols were performed during 2 weeks. The evaluations performed were grip strength tests and histologic analysis.RESULTS:
both, grip strength and histomorphometric evaluations (fiber numbers and axon density) did not present significant differences between the treated and lesion groups, however, in the morphological evaluation it was possible to distinguish characteristics of the repair process for the treated groups.CONCLUSION:
a slight qualitative improvement was observed for the treated groups, especially when it was associated PRF with free swimming.(AU)
