EFEITOS DA LASERTERAPIA NA REGENERAÇÃO NERVOSA PERIFÉRICA

Objective: The influence of dose of low power lasertherapy (AsGaAl, 830 nm) on the regeneration of the fibular nerve of rats after a crush injury was evaluated by means of the functional gait analysis and histomorphometric parameters. Methods: Controlled crush injury of the right common fibular nerve, immediately followed by increasing doses (G1: no irradiation; G2: simulated; G3: 5 J/cm2 ; G4: 10 J/cm 2 ; G5: 20 J/cm 2 ) laser irradiation directly on the lesion site for 21 consecutive days. Functional gait analysis was carried out at weekly intervals by measuring the peroneal/fibular functional index (PFI). The animals were killed on the 21 st postoperative day for removal of
