The first point of the S/D curve will be plotted and the pulse width will
decrement to the next width setting. It will now be necessary to increase the
output intensity until muscle contraction occurs again – at this point press
‘Next’ and the next point in the S/D curve will be plotted.
Repeat this process until the ‘End’ pulse width is reached. The S/D curve is
now plotted. Waiting for or pressing ‘Stop’ or manually reducing the output
to zero will cause the Rheobase and Chronaxie to be calculated and
displayed.
Pressing ‘OK’ will return to the S/D curve set-up screen to allow another test
to be run.
Note: As the S/D curve set-up is not appropriate to use in Combination
therapy, the Combination button will be found to be greyed-out and
inoperable if S/D curve was previously selected. Choose a different
stimulation setting if Combination treatment is required.
