Restless legs syndrome (RLS), also called Willis-Ekbom disease, is a neurological condition that affects an estimated 5 to 10 percent of adults in Canada and many other countries. It produces an uncomfortable urge to move the legs, usually worse at rest and in the evening, and it can have a significant impact on sleep. While medications and lifestyle measures are the foundation of treatment, many Canadians ask whether compression hosiery has a role to play. This article summarises what RLS actually is, what the small body of research on compression has shown, and how compression typically fits alongside other strategies. It is general information and not a substitute for medical advice.
What is restless legs syndrome?
RLS is a sensorimotor disorder. The four core diagnostic features, as summarised by the National Institute of Neurological Disorders and Stroke, are:
- An urge to move the legs, usually accompanied by uncomfortable sensations.
- Symptoms that begin or worsen during rest or inactivity.
- Symptoms that are partially or totally relieved by movement.
- Symptoms that are worse in the evening or at night.
People describe the sensations differently — crawling, tugging, electrical, fizzy, or restless. Severity ranges from a mild evening nuisance to nightly sleep disruption that affects daytime functioning.
What causes RLS?
RLS is thought to involve abnormalities in dopaminergic pathways and iron metabolism in the brain. It can be primary (with a strong family history) or secondary to other conditions such as iron deficiency, kidney disease, pregnancy, peripheral neuropathy, or certain medications. A thorough assessment usually includes blood work to check iron stores, especially ferritin, which is often a target of treatment.
How compression has been studied for RLS
Compression hosiery is not a first-line treatment for RLS, and current major neurology guidelines do not list it as a primary intervention. However, a small body of literature has explored mechanical interventions, including compression. The most cited study is a 2013 randomised pilot trial that compared medical-grade compression stockings with sham stockings in adults with RLS. Participants who wore the active stockings reported reduced RLS symptoms compared with the sham group, though the study was small and short. The trial is indexed by the National Library of Medicine for readers who want to explore it directly. Subsequent reviews have noted that more research is needed before compression can be considered an evidence-based treatment for RLS.
This is the careful framing most Canadian clinicians use: compression hosiery is not a cure for RLS, but some patients report that wearing graduated compression stockings in the evening reduces the intensity of their symptoms enough to fall asleep. Because compression is low-risk for most adults without arterial disease, it is a reasonable adjunct to discuss with a physician once standard care has been considered.
How compression might help
Several proposed mechanisms could explain why some people experience relief from compression in the evening:
- Graduated compression reduces venous pooling, which can ease the heavy, restless feeling some people experience after long periods of standing or sitting.
- Steady pressure provides a constant low-level sensory input that may, in some individuals, blunt the urge to move.
- By improving venous return, compression may help those whose RLS is exacerbated by chronic venous insufficiency.
None of these are definitive. They are reasonable hypotheses that are still being explored in clinical research.
What pressure class is typically used?
For RLS adjunctive use, most discussion in the literature centres on 15-20 mmHg compression. This is a milder, generally well-tolerated class that delivers measurable graduated pressure without being uncomfortable to wear for several hours in the evening. Browse 15-20 mmHg compression socks for typical options. Some patients with overlapping venous disease wear 20-30 mmHg stockings during the day for those venous symptoms and find that the evening RLS is less intense as a side effect of better venous return.
How to try compression for RLS
If you and your physician decide to trial compression hosiery for RLS, a few practical points help:
- Choose graduated medical-grade compression rather than novelty athletic sleeves. The graduated profile is what produces the venous and sensory effects.
- Knee-high stockings are usually sufficient because RLS symptoms most often centre on the calves.
- Put the stockings on a few hours before bedtime to capture the period when symptoms typically peak.
- Remove the stockings before sleep unless your physician specifically advises otherwise. Venous pressure is low when you are horizontal, so overnight compression is rarely necessary and can interfere with sleep comfort.
- Track your experience for two to four weeks. RLS varies day to day, and a brief trial can be misleading.
Foundational RLS care to consider in parallel
Compression is, at most, an adjunct. Foundational RLS care typically includes:
- Iron evaluation. Many RLS patients have low brain iron stores; serum ferritin is commonly checked, and iron supplementation may be prescribed.
- Medication review. Some antidepressants, antihistamines, and anti-nausea drugs can worsen RLS.
- Caffeine, alcohol, and nicotine moderation. All three can worsen symptoms in many people.
- Sleep hygiene. Regular schedules and a cool, dark bedroom reduce baseline sleep instability.
- Exercise. Moderate daily activity is associated with milder symptoms; very heavy late-evening exercise can sometimes worsen them.
- Prescription therapies. When indicated, physicians may prescribe alpha-2-delta ligands, dopaminergic agents, or other medications. Choice has shifted in recent years to reduce the risk of augmentation, a long-term complication of some dopaminergic drugs.
Who should not use compression for RLS
Compression hosiery is contraindicated or requires medical supervision in several situations:
- Moderate to severe peripheral artery disease.
- Untreated cellulitis or infected skin on the legs.
- Significant peripheral neuropathy with sensation loss.
- Decompensated heart failure.
This is not a comprehensive list. A physician should review the legs before recommending compression, especially in older adults with overlapping conditions.
Putting it together
Restless legs syndrome is a real neurological condition with established medical treatments, and compression hosiery is not a substitute for that care. The current literature is small but suggestive that, for some adults, evening use of graduated 15-20 mmHg compression stockings may reduce symptom intensity enough to support sleep. Because compression is low-risk for most healthy adults, it is reasonable to explore as part of a broader RLS plan in conversation with a physician. People with overlapping venous disease may notice broader benefits beyond the RLS symptoms themselves.
Frequently asked questions
Is compression an evidence-based treatment for RLS?
No. The evidence base is small and exploratory. Major neurology guidelines do not list compression as a primary treatment, though some patients report symptom relief.
What pressure class should I try?
15-20 mmHg graduated compression is the most commonly discussed class for RLS adjunctive use. Pressure decisions should be confirmed with your physician.
Can I wear compression to bed?
Most clinicians recommend removing compression at bedtime. Venous pressure is low when horizontal, and overnight wear is rarely necessary.
How quickly might compression help?
If compression helps you, the effect is usually felt within the first few evenings. Trial it for two to four weeks before deciding.
Will compression help if my RLS is from iron deficiency?
The underlying iron deficiency needs to be diagnosed and treated. Compression may help with comfort, but it is not addressing the root cause.
