How much does a rock weigh? Trains come in all shapes and sizes, from a single-carriage passenger train (approx 40t) to freight trains with multiple locos, dozens of wagons and hundreds of tons of cargo. A ballpark figure of about 200t probably covers a lot of passenger D/EMUs. Formations can be made up of one or more D/EMUs.
Electrotherapy is a medical technique in which an electric current is used to perform a wide variety of tasks associated with pain, neurological disorders, muscle-related conditions, and drug delivery. Electrotherapy includes a range of medical techniques, some of which are under much debate and criticism.
Electrotherapy (and more specifically Interferential-IF-Stimulation) has three major clinical benefits: the reduction of pain, the stimulation of healing and the reduction in recovery time.Pain reduction occurs because the applied electrical fields act to close the body's pain gate mechanism.n addition, electrical stimulation causes the body to produce more endorphins -- pain reducing chemicals made naturally by the body. Interferential Stimulation also activates the body's motor nerves. This results in increased blood flow and reduced edema (excess fluid). Electrotherapy is safe and comfortable.
