Restless Legs Syndrome (Willis-Ekbom Disease)
A sensorimotor neurological disorder characterized by an uncontrollable urge to move the legs, usually accompanied by uncomfortable or unpleasant sensations. These symptoms typically occur or worsen during periods of rest or inactivity, such as sitting or lying down, and are partially or totally relieved by movement. The symptoms follow a circadian pattern, worsening in the evening or at night.
Prevalence: Affects approximately 5-10% of adults in North America and Europe. It is twice as common in women as in men. Can affect children (often misdiagnosed as growing pains or ADHD).
Common Symptoms
- Overwhelming, irresistible urge to move the legs
- Uncomfortable sensations described as creeping, crawling, pulling, itching, tingling, burning, or aching
- Sensations typically located deep within the calf muscles, but can affect thighs or feet
- Symptoms worsen significantly during periods of inactivity (sitting in a car, watching TV, lying in bed)
- Symptoms follow a circadian rhythm, being most severe in the evening and at night
- Immediate and temporary relief obtained by movement (walking, stretching, shaking legs)
- Involuntary leg twitching or jerking during sleep (Periodic Limb Movements of Sleep - PLMS)
- Difficulty falling asleep due to leg discomfort
- Frequent nighttime awakenings
- Daytime sleepiness and fatigue due to poor sleep quality
- Restlessness and inability to sit still for long periods
- Mood disturbances including irritability and anxiety
Risk Factors
- Female gender
- Pregnancy (especially third trimester)
- Family history of RLS (genetic link)
- Iron deficiency or anemia
- End-stage renal disease (kidney failure)
- Peripheral neuropathy (diabetes)
- Medication use (SSRIs, tricyclics, dopamine antagonists, antihistamines)
- Smoking and alcohol use
- Age (risk increases with age)
Treatment Approaches
- Iron replacement therapy (oral or IV iron)
- Alpha-2 delta ligands (gabapentin, pregabalin, gabapentin enacarbil) - First-line treatment
- Dopamine agonists (pramipexole, ropinirole, rotigotine patch) - Caution due to augmentation risk
- Opioids (low dose) for severe refractory cases
- Review and discontinuation of triggering medications (e.g., switching antidepressants)
- Cognitive Behavioral Therapy for Insomnia (CBT-I)
- Sleep hygiene education
Self-Help & Natural Approaches
- Moderate aerobic exercise (walking, cycling) - avoid intense exercise late in day
- Leg massage before bed to relax muscles
- Warm baths or heating pads to soothe muscles
- Cold packs (some find cold more effective than heat)
- Stretching exercises focusing on calves and hamstrings
- Yoga and relaxation techniques to reduce muscle tension
- Compression socks or stockings
- Pneumatic compression devices (foot pumps)
- Vibration pads placed under legs
- Mental alerting tasks (crosswords, video games) during rest periods to suppress urges
- Relaxis pad (counter-stimulation device)
- Avoiding prolonged sitting in evenings

- Sleep is significantly disrupted
