EMS is effective in helping people recover from injuries and surgery, warming-up prior to a workout, helping people relax, managing pain, and treating sore aching muscles in the aftermath of a strenuous workout. Many people also use the electrical muscle stimulation machine to help relieve pain and others as a way to help burn fat. Muscle stimulation can also help in the repair and recovery of joints that have been injured while playing sports. And EMS is being used to help those suffering from impaired movement (such as stroke victims) to prevent muscle atrophy and regain movement, if only on a limited scale.
