Two main treatments that provide electrical stimulation therapy are: ● TENS TENS is known as transcutaneous electrical nerve stimulation. It is often used for long-term (chronic) pain and short-term (acute) pain. ● EMS EMS is known as electrical muscle stimulation; it is often used for the stronger current that the other electrical stimulation device is able to contract. However, other electrical stimulation therapies are similar to what electrical stimulation therapy offers:   ● Electrical stimulation for tissue repair ● Interferential current ● Neuromuscular electrical stimulation ● Functional electrical stimulation ● Spinal cord stimulation ● Iontophoresis
