Electrotherapy

[Gourav]

In 1855 Guillaume Duchenne, the promoter of the Electrotherapy, announced that the alternancia was superior to the direct current for electrotherapeutic triggering of the muscular contractions. What it calls the “heating to affect” of the direct currents irritates the skin, since, if the intensity of the necessary voltage for the muscular contractions, that cause that the skin blisters (in the anode) and of well (in the cathode). In addition, with each contraction DC it requires that the current stops and is reinitiated. On the other hand the alternating current can produce strong muscular contractions, of the condition of the muscle independently, whereas DC-induced the contractions were strong if the muscle is strong and weak if the muscle is weak.

Since then it has been almost all the participation rehabilitation of the muscular contraction does with a rectangular symmetrical two-phase wave. During the decade of 1940, nevertheless, the US. Department military, the investigation of the application of the electrical stimulation not only to delay and to prevent the atrophy, but to recover the muscular mass and forces, used what the galvanic exercise in the atrophied hands of the patients was denominated who had an injury of the ulnar nerve of a surgery in a wound. These exercises galvanic used a single-phase, current waveform electrochemical.
