Time Course of the Soleus M Response and H Reflex after Lidocaine Tibial Nerve Block in the Rat

Figure 5

Mean time course of the amplitude of M and H responses, expressed in relation to baseline values, at the initial phase of decline after application of lidocaine. Time (minutes) after application of lidocaine (performed at time 0) is shown on the 𝑥-axis. The mean amplitude of the M and H responses of the 18 rats expressed in relation to baseline values (corresponding to the mean of 10 M and H responses studied before application of lidocaine) is shown on the 𝑦-axis. Time courses and the regression line of the M response are shown in black and the time courses and regression line of the H reflex are shown in gray. The interval shown on the curve corresponds to the standard error.
