Abstract

This study aimed at evaluating and comparing the effects of low-level laser therapy (LLLT) and a forced swimming training in a joint nociception model on Wistar rats, in order to functionally register pain by observation of paw elevation time (PET) during gait on a metal cylinder. Thirty-two Wistar rats were divided into four groups: CG-untreated animals submitted to nociception induction on right knee; LG-nociception and treated with 670 nm and 8 J/cm2 LLLT; SG-nociception and swimming for 10 minutes in water at 30-32° C; SLG-nociception and treated with swimming and laser. To achieve the nociception, 50 μL of 5% formalin were injected in the medial tibiofemoral space of each animal. Pain was assessed according to a functional incapacity test, which registered paw elevation time (PET) as well as their gait for one minute on a metallic cylinder. The evaluations occurred before nociception induction (EV1), after 15 minutes (EV2) and after 30 minutes (EV3) of it, with treatment protocols being administered after EV2. The analyses showed that LLLT was the only group to present the restoration values in the EV3 when compared to EV1. SG was the only one which did not show any reduction when compared to EV2 and EV3. Hence, it can be inferred that, by functional evaluation, LLLT had some analgesic effects, while the swimming treatment produced pain increase, which was partially reversed by the use of LLLT.

Fatores associados à prática insuficiente de atividade física em professores escolares brasileiros: um estudo de revisão integrativa

“…Com tais resultados, é possível notar que se torna importante a prática de atividade física regular, já que é considerado um tratamento não medicamentoso e uma ação preventiva eficaz, além de ser um mecanismo de controle de peso, regulação de gordura corporal e de prevenção de doenças cardiovasculares, itens importantes quando se trata da saúde dos professores (WORLD HEALTH ORGANIZATION, 2010; THE EUROPEAN SOCIETY OF CARDIOLOGY, 2012;GHORAYEB et al, 2013).…”
