Outline of Final Research Achievements |
We investigated the effects of neuromuscular electrical stimulation (ES) training with eccentric contraction (ECC) on skeletal muscle dysfunction in adjuvant-induced arthritis (AIA) rat. AIA was induced by an injection of complete Freund’s adjuvant. ES was applied every other day for three weeks. There was a reduction in specific force production in skinned fibers from medial gastrocnemius (MG) muscles from AIA rats, which was accompanied by the aggregation of actin. Moreover, the protein expressions of the pro-oxidative enzymes NADPH oxidase, neuronal nitric oxide synthase, and p62 were increased in AIA EDL muscles. These deleterious changes were prevented by ES training. The present data suggest that NMES training prevents AIA-induced skeletal muscle weakness presumably by counteracting the formation of actin aggregates. Thus, ES training with ECC can be effective in treatment of muscle dysfunction seen in patients with arthritis disorders.
