Interferential current therapy

Interferential current therapy or IFC is treatment involving applying an electrical current to the skin using an alternating current. IFC is well-established treatment and is typically used for pain relief, muscle stimulation, to reduce swelling and to activate the autonomic nervous system (ANS). It is most commonly used in combination with other treatments such as ultrasound treatment.

Evidence
Very few studies have conducted trials of interference current therapy in patients with fibromyalgia that included a control group, but there is limited evidence of the effectiveness of IFC for pain and sleep problems in fibromyalgia.
