Economy - Etymology. 1  The English words economy and economics can be traced back to the Greek word Î¿á¼°ÎºÎ¿Î½ÏÎ¼Î¿Ï (i.e. household management), a composite word derived from Î¿á¼¶ÎºÎ¿Ï (house;household;home) and Î½Î­Î¼Ï (manage; distribute;to deal out;dispense) by way of Î¿á¼°ÎºÎ¿Î½Î¿Î¼Î¯Î± (household management).
Today many people confuse TENS with electrical muscle stimulation (EMS). EMS and TENS devices look similar, with both using long electric lead wires and electrodes. TENS is for blocking pain, where EMS is for stimulating muscles.
