Transcript of Electrotherapy
It also blocks the nerves in the system that produce pain. Healthcare providers.
During 1855 Guillaume Duchenne, the developer of electrotherapy, announced that alternating was superior to direct current for electrotherapeutic triggering of muscle contractions. What he called the 'warming affect' of direct currents irritated the skin, since, at voltage strengths needed for muscle contractions, they cause the skin to blister and pit. Furthermore, with DC each contraction required the current to be stopped and restarted. Moreover alternating current could produce strong muscle contractions regardless of the condition of the muscle, whereas DC-induced contractions were strong if the muscle was strong, and weak if the muscle was weak.
