During this period, then, daily stimulation of the affected muscles is necessary, the galvanic current being employed until response is obtained with the faradic current ; both are then employed for a time till finally the faradic current is employed alone .as described under the procedure for Graduated Contractions. Resisted exercises form the last stage of treatment for the recovering muscles upon the return of voluntary power. The same considerations apply, then, to the care of a limb immobilised from paralysis through injury to a muscle-nerve as apply to the care of a limb with fractured bone. There is the same liability to adhesions of joints, of muscle-tendons to their sheaths, and of muscle-wasting as with any other cause of immobiUsation ; but the muscle-wasting is infinitely more serious, the muscles require a special type of electrical stimuli for their contraction, and the period of treatment must continue till the nerve has been repaired and is able to conduct voluntary impulses. Exhaustive study, by the late Dr. Lewis Jones, of the problem of obtaining a standardised instrument as regards impulse length voltage and rate of inter- ruption, which would supply impulses of any required length, resulted in the production of his condenser apparatus, which in turn has undergone some slight further modifications. It is only by such an instru- ment that any satisfactory investigation of the exact condition of a muscle is possible. With its help we can detect defect in a muscle which appears to re- spond well to voluntary effort ; we can ascertain improvement in a muscle which is still unable to respond to
