Restless legs syndrome and near-infrared light: An alternative treatment option

Abstract

There are few treatment options in managing restless legs syndrome (RLS); the most frequently used are dopaminergic drugs and movement. New treatment options are highly sought after. This study evaluated the effectiveness of monochromatic near-infrared light treatment in decreasing symptoms associated with RLS. The design used was 2×6 repeated-measures design with two groups (treatment and control) and six repeated measures (baseline, weeks 1-4, and posttreatment). Data collection took place in the university modalities laboratory. Thirty-four volunteers with symptoms of RLS were randomly assigned to a treatment or control group. Over a 4-week period subjects underwent twelve 30-min treatments to their lower legs with near-infrared light. The International RLS rating scale (IRLS) was used to assess and track patient symptoms. There was a steady decrease in symptoms associated with RLS over the 4 weeks in the treatment group. After 4 weeks of treatment the treatment group had a significantly greater improvement in restless legs syndrome symptoms than the control group (p<0.001); improvement was still significant after 4 weeks posttreatment compared to baseline (p<0.001). Treatment with near-infrared light does decrease symptoms associated with RLS as demonstrated in lower IRLS scores. This new noninvasive method of treating RLS might become a valuable new management option. More research is needed to determine the mechanism(s) behind infrared light treatment and RLS.

“…155 Lifestyle modifications including exercise, 178 sleep hygiene, massage, and warm water baths, may help ameliorate the symptoms. 179 Other therapies including acupuncture, 180 pneumatic compression devices, 181 and near infrared light 182 have been evaluated for RLS in small studies.…”

Sleep improvement for restless legs syndrome patients. Part I: pooled analysis of two prospective, double-blind, sham-controlled, multi-center, randomized clinical studies of the effects of vibrating pads on RLS symptoms

“…Three physical RLS treatment modalities have been evaluated with the randomized clinical trial (RCT) design: leg compression, 39 leg heating, 40,41 and leg vibration. Compression therapy assumes that leg venous and/or lymphatic stasis (insufficiency) contributes to or causes RLS.…”

“…40 Three times a week, over 4 weeks, each leg was wrapped with a pad for half-hour treatments. Treatment was not coincident with RLS attacks.…”

Stabilization Versus McKenzie Exercises in Patients With Mechanical Neck Dysfunction

“…Instruments Visual Analogue Scale (VAS): The tester used the VAS to measure current pain intensity, average pain intensity over the past 2-3 days, and the worst level of pain experienced during the past 2-3 days. The tester calculated the mean of the scores to provide a valid and reliable pain measure score [13]. Neck Disability Index (NDI): The tester used the NDI to measure functional disability.…”
