dc.description.abstractThe aim of this study was to evaluate the kinematic and sensorimotor parameters after application of photobiomodula- tion (PBM) in rats with experimentally induced spinal cord injuries (SCI). The animals were randomly divided into 3 experimental groups containing 5 animals each and respecting the following arrangement: C (control, simulation of sur- gical procedures); I (injury, induction of SCI) and PBM (photobiomodulation, SCI+application of photobiomodulation therapy). All animals underwent movement tests after 3, 7, 10 and 14 days, respectively, after the surgical procedure, and the following movement parameters were evaluated: mean velocity (MV), ground reaction force (GRF) and sciatic func- tional index (SFI) using integrated equipment capable of digitally collecting the proposed data. The mean results of the MV data obtained by groups C, I and PBM were compared and a statistically significant difference was found, being: C x I (p=0.001) and I x PBM (p=0.002), respectively. Considering the SFI data obtained by groups C, I and PBM, a statisti- cally significant difference was observed when comparing C x I (p = 0.011). The mean results of the GRF data obtained by groups C, I and PBM were compared and the results showed a statistically significant difference in C x I (p=0.001), C x PBM (p=0.026) and I x PBM (p=0.002), respectively. Therefore, there was an improvement in motor function between the 7th and 14th day after SCI, represented by the increase in speed and better GRF distribution in the PBM group.
