By using theinterrupting handle (Fig. 114) the rapidly interrupted current can beused when individual muscles are treated. In using the slowly inter-rupted current we may take both electrodes of equal and medium sizein the hand, as in Fig 169; then, with a current just strong enough toproduce contraction, the two electrodes are placed over the belly ofeach muscle, being treated one after the other.

That is, if we weretreating the muscles of the thigh, we would first place them over therectus femoris, causing eight or ten contractions in it, then over thevastus internus, causing the same number of contractions in it, thenover the vastus externus, and so on. Another method is to place one electrode of good size at some indif- STIMULATION ferent point, preferably over or near the nerve trunks suppl^dng themuscles being treated, while the other electrode of smaller size is placedover the motor points of each muscle in turn, and contractions caused Fig. 169. Method of holding electrodes in one hand. (Mills.) as above described (Figs. 154 and 172). A combination of the influencesof massage and electricity may be obtained by employing a roller elec-trode (Figs. 170 and 171) as the active one. This, of course, is rolled Fig. 170
