What is EMS?

An injured muscle usually experiences little if any movement. EMS therapy remedies this by using low voltages to stimulate motor nerves to cause involuntary muscular contractions. Like exercise, EMS helps strengthen the injured area, and has been found to effectively treat a variety of musculoskeletal and vascular conditions. Common candidates for EMS therapy are patients recovering from orthopedic surgery, muscle strains or tears, or athletes who have undergone cartilage or tendon repair. EMS is non-invasive and does not use pharmaceuticals.

  • Relaxation of muscle spasm 
  • Prevention or retardation of disuse atrophy 
  • Increasing local blood circulation 
  • Muscle re-education 
  • Immediate postsurgical stimulation of calf muscles to prevent venous thrombosis 
  • Maintaining or increasing range of motion
    Powered muscle stimulators should only be used under medical supervision for adjunctive therapy for the treatment of medical diseases and conditions.

  • This device should not be used by patients with cardiac demand pacemakers.
