E.M.S. stands for Electrical Muscle Stimulation. EMS is predominately used by doctors to prevent, or reduce, muscle atrophy. Atrophy is the weakening and loss of muscle tone, which is usually experienced after surgeries or injuries. Doctors also see EMS as a means of increasing blood flow to muscles, increasing range of motion, increasing muscle strength, as well as enhancing muscle endurance. EMS also has pain management attributes in regards to muscle related pain, such as a spastic muscle, sore muscles, or tight muscles. While using the EMS, the brain sends a nerve impulse to the “motor point” of your muscle. This signal is a message to the muscles to expand and contract. Electrodes are placed over the motor points of the muscle group to be exercised. When the stimulation is applied through the pads, the signal finds its way to these motor points and causes the muscle to expand and contract. This makes it possible to duplicate a conventional exercise, similar to an isometric exercise. Electrical muscle stimulation uses an outside electrical source that stimulates the nerves to send signals to your muscle to expand and contract. This is done by sending electrical current through self adhesive electrodes placed over the muscle. The current passes through your skin to the nerves in that area, causing the muscle to expand and contract. EMS can increase muscle growth, endurance and strength.
