Resumen
Objective: To verify the functionality through muscle grip strength in animals with obesity induced by monosodium glutamate (MSG) and in control animals, which suffered compression of the right median nerve, and treated with swimming with overload. Methods: During the first five days of life, neonatal Wistar rats received subcutaneous injections of MSG. The control group received a hypertonic saline solution. Forty-eight rats were divided into six groups: G1 (control); G2 (control + injury); G3 (control + injury + swimming); G4 (obese); G5 (obese + injury); G6 (obese + injury + swimming). The animals in groups G2, G3, G5 and G6 were submitted to compression of the median nerve and G3 and G6 groups were treated, after injury, with swimming exercise with load for three weeks. The swimming exercise had a progressive duration, according to the week, of 20, 30 and 40 minutes. Muscle strength was assessed using a grip strength meter preoperatively and on the 3 rd, 7 th, 14th and 21st days after surgery. The results were expressed and analyzed using descriptive and inferential statistics. Results: When the grip strength was compared among assessments regardless of group, in the second assessment the animals exhibited lower grip strength. G1 and G4 groups had greater grip strength, compared to G2, G3, G4 and G6. Conclusion: The swimming exercise with overload has not been effective in promoting improvement in muscle grip strength after compression injury of the right median nerve in control and in obese-MSG rats. © 2013 Elsevier Editora Ltda. 55 1 43 47 Cavalcante, V.E.V., Montenegro, E.J.N., Pontes Filho de, N.T., Efeitoda eletroestimulação no músculo desnervado de animais:revisão sistemática (2012) Fisioter Mov., 25, pp. 669-678 Stafford, M.A., Peng, P., Hill, D.A., Sciatica: a review of history, epidemiology, pathogenesis, and the role of epidural steroidinjection in management (2007) Br J Anaesth., 99, pp. 461-473 Gordon, T., The role of neurotrophic factors in nerveregeneration (2009) Neurosurg Focus., 26, p.
