Electrical stimulation can be used to relieve pain, reduce inflammation, providebiofeedback to enhance muscle contraction, and promote muscle relaxation. All electrical stimulation should be comfortable. Most people are familiar with a TENS unit. TENS stands for transcutaneous electrical nerve stimulation. In certain cases, this mode of stimulation can assist in blocking pain signals from getting to the brain. Instead, sensations generated by the TENS unit reaches the brain first.
Interferential electrical stimulation is a mode commonly used in the clinic to promote relaxation.
Pulsed biphasic electrical stimulation helps to fatigue spasming muscles or promote improved circulation through a muscle pump method.
High volt electrical stimulation can assist in diminishing swelling.
Neuromuscular electrical stimulation is normally used to strengthen connection between the nervous system and musculoskeletal system. For example, after a patient has anterior cruciate ligament reconstruction, the patient will experience quadriceps atrophy. An NMES unit is applied in therapy after the surgery in order to regain a solid muscle contraction.
