Devices to Treat Restless Legs Syndrome

There are several theories for what causes the unpleasant sensation of restless legs syndrome (RLS). Several neurotransmitters are thought to be involved. Iron stores also have a significant role in RLS.

Devices for RLS generally use compression, massage, stimulation, or vibration to relieve unpleasant sensations in the legs. Most of this equipment is not approved or tested by the US Food and Drug Administration (FDA). Only 2 devices – the Restiffic foot wrap and Nidra by Noctrix – are currently approved by the FDA to treat RLS.^1-3

The appeal of devices is that they do not have side effects, the way some RLS drugs do. Some people find that these devices work, while others do not. Restiffic was studied and was found to be clinically effective. Nidra has been tested in a clinical setting and was also clinically effective. Both require a prescription from your clinician.^1-3

These devices may be a good option for people who cannot take medicine for RLS, such as people who are pregnant or people with end-stage kidney disease. Some people find great relief while others find little.⁴

Restiffic foot wraps

Restiffic foot wraps provide a type of acupressure to specific muscles in the feet. The device includes 2 foot wraps that go around the center of each foot. The wraps exert gentle pressure on the abductor hallucis and flexor hallucis brevis muscles on the bottom of the foot.^2,5

Researchers think the foot wraps tell the brain to relax your leg muscles, which can reduce the sensations of RLS.^2,5

Restiffic requires a prescription from your doctor.^2,5

Nidra Tonic Motor Activation System

This is a device worn on both legs just under the knees. It has been clinically proven to be effective. It was tested in people who did not receive enough relief from medicine alone. It stimulates your nerves to activate your muscles and provides similar relief to walking around. It is worn when you go to bed. It is FDA-approved and requires a prescription from your doctor.⁶

Compression devices

Some people find that compression socks or compression devices that fit over the legs help relieve the symptoms of RLS. The theory is that compression increases blood flow, which increases oxygen levels in the tissue. In turn, this reduces the muscle contractions and nerve sensations of RLS.¹

Near-infrared light devices

Near-infrared light devices include 4 pads that are attached around the leg and a power cord. The idea is that the device emits light that stimulates blood flow in the muscles. This extra blood flow is thought to decrease RLS symptoms.¹

Relaxis pad

Relaxis was FDA-approved but is no longer clinically available by prescription. It is a pad placed under the legs that vibrates. The theory is that the vibrations stimulate the nerves, which interrupts the signals that cause the uncomfortable sensations in the legs.^1,3

Other devices for restless legs syndrome

Weighted blankets and hot or cold pads help some people. Online stores carry a wide variety of vibrating mats, leg massagers, leg pillows, and electrical nerve stimulators for RLS.⁵

Other treatments for restless legs syndrome

Home remedies are popular and often provide at least some relief from the leg sensations. Diet and lifestyle changes also help many people with RLS. These include getting regular exercise, reducing caffeine, and reducing alcohol.⁷

Several prescription drugs are available for moderate to severe RLS. Mild RLS is most often treated with nondrug therapies. Iron pills or an iron infusion are sometimes prescribed to help with RLS symptoms.⁷

Before beginning treatment for RLS, tell your doctor about all your health conditions and any other drugs, vitamins, or supplements you are taking. This includes over-the-counter drugs, including sleep aids.
