RESUMO
The twitch properties of denervated muscle were found to be altered contributing to the derangement in the contractile machinery of the denervated muscle. Cathodal polarity treatment minimized the fluctuations and tried to restore denervated muscle back to normalcy to some extent. The anodal polarity treatment was not able to produce favourable effect. The differential effect of polarity treatment on the contractile kinetics of the denervated muscle is discussed.

The activity levels of succinate dehydrogenase (SDH), malate dehydrogenase (MDH) and cytochrome-C-oxidase showed a decrement whereas lactate dehydrogenase (LDH) evinced maximum activity during first 3 days of denervation. Under the impact of cathodal polarity treatment an elevation in the activity levels of these 4 enzymes was relatively more potent when compared to anodal polarity treatment. The role of polarity treatment in the regulation of these oxidative enzymes was discussed.
