Electrical Stimulation for the Treatment of Arthritis

DESCRIPTION

Electrical and electromagnetic stimulation are being investigated to improve functional status and relieve pain related to osteoarthritis and rheumatoid arthritis that are unresponsive to standard therapies. Noninvasive electrical stimulators generate a weak electrical current within the target site using pulsed electromagnetic fields, capacitive coupling, or combined magnetic fields. In capacitive coupling, small skin pads/electrodes are placed on either side of the knee or wrist. Electrical stimulation is provided by an electronic device that noninvasively delivers a sub-sensory low-voltage, monophasic electrical field to the target site of pain. Pulsed electromagnetic fields are delivered via treatment coils placed over the skin. Combined magnetic fields deliver a time-varying field by superimposing that field onto an additional static magnetic field.

It is proposed that pulsed electrical stimulation treats the underlying cause of arthritis by stimulating the joint tissue and improving the overall health of the joint to provide a slow-acting, but longer-lasting improvement in symptoms. Pulsed electrical stimulation is proposed to be similar to bone stimulator therapy for fracture nonunion.

ADDITIONAL INFORMATION  

No studies were found for the use of electrical stimulation for rheumatoid arthritis and only a few, small trials were found pertaining to the use of electrical stimulation for treating knee osteoarthritis. There is a lack of evidence showing improved health outcomes with the use of electrical stimulation in comparison to other available treatments for the treatment of arthritis. Therefore this technology remains investigational.
