| Abstract: | The system is designed for data-acquisition and computationof a relatively large nwnber of parameters of a single twitchor tetanic contraction generated by an electrically stimulatedskeletal muscle. The parameters that can be computed using theprogram facilities are: (i) the rise time (Tc), 50% relaxationtime (50% Tr) and the maximwn tendon (Pt) of the twitch contraction;(ii) the approximate number of motor units innervating the muscleand the fatigue index; (iii) the fission frequency of the tetaniccontraction and the twitch to tetanus ratio; (iv) the maximumtetanic tension (P0) and its Tc and 50% Tn (v) the P0 versusmuscle length diagram; (vi) the fatigue-time course. |
