Electrotherapy

Electrotherapy is the use of electrical energy as a medical treatment. In medicine, the term electrotherapy can apply to a variety of treatments, including the use of electrical devices such as deep brain stimulators for neurological disease. The term has also been applied specifically to the use of electric current to speed wound healing. Additionally, the term "electrotherapy" or "electromagnetic therapy" has also been applied to a range of alternative medical devices and treatments. Electrotherapy is primarily used in physical therapy for: relaxation of muscle spasms prevention and retardation of disuse atrophy increase of local blood circulation muscle rehabilitation and re-education electrical muscle stimulation maintaining and increasing range of motion management of chronic and intractable pain including diabetic neuropathy acute post-traumatic and post-surgical pain post-surgical stimulation of muscles to prevent venous thrombosis wound healing drug delivery Some of the treatment effectiveness mechanisms are little understood, with effectiveness and best practices for their use still anecdotal. In general, there is little evidence that electrotherapy is effective in the management of musculoskeletal conditions. In particular, there is no evidence that electrotherapy is effective in the relief of pain arising from osteoarthritis, and little to no evidence available to support electrotherapy for the management of fibromyalgia. A 2016 review found that, "in evidence of no effectiveness," clinicians should not offer electrotherapy for the treatment of neck pain or associated disorders. Earlier reviews found that no conclusions could be drawn about the effectiveness of electrotherapy for neck pain, and that electrotherapy has limited effect on neck pain as measured by clinical results. A 2015 review found that the evidence for electrotherapy in pregnancy-related lower back pain is "very limited". A 2014 Cochrane review found insufficient evidence to determine whether electrotherapy was better than exercise at treating adhesive capsulitis.

Therapy
A therapy or medical treatment (Both words, "Treatment" and "Therapy" are often abbreviated tx, Tx, or Tx) is the attempted remediation of a health problem, usually following a medical diagnosis. As a rule, each therapy has indications and contraindications. There are many different types of therapy. Not all therapies are effective. Many therapies can produce unwanted adverse effects. Medical treatment and therapy are generally considered synonyms. However, in the context of mental health, the term therapy may refer specifically to psychotherapy.
Electrical muscle stimulation
Electrical muscle stimulation (EMS), also known as neuromuscular electrical stimulation (NMES) or electromyostimulation, is the elicitation of muscle contraction using electric impulses. EMS has received an increasing amount of attention in the last few years for many reasons: it can be utilized as a strength training tool for healthy subjects and athletes; it could be used as a rehabilitation and preventive tool for people who are partially or totally immobilized; it could be utilized as a testing tool for evaluating the neural and/or muscular function in vivo.
Capacitor
A capacitor is a device that stores electrical energy in an electric field by accumulating electric charges on two closely spaced surfaces that are insulated from each other. It is a passive electronic component with two terminals. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.
