[New method of iterative measurement of muscular force in normal and dystrophic mice].

A new method is described, to perform repeated measures of twitch and tetanic tensions during isometric contractions of the tail's extensor muscles, in anesthetized mice. The results obtained from 20 normal and 15 dystrophic (S57 BL/6J dy/dy) mice are presented. This method may be a good tool for long term therapeutic trials in dystrophic mice.
