The expected results of this study will have a significant impact on the treatment of RLS/WED patients. Magnesium supplementation (if proven to be beneficial) can be utilized as an inexpensive, safer, biologically plausible alternative to dopamine agonists and α2δ calcium-channel ligands.
This is an open-label, prospective, non-placebo controlled pilot study. 15 subjects with a diagnosis of restless legs syndrome (ICSD-3 diagnostic criteria) will be recruited from OSF Healthcare Saint Francis Medical Center sleep center and Illinois Neurological Institute. RLS/WED patients who meet inclusion and exclusion criteria during the initial clinic visit will be offered study participation. Standard treatment options will be discussed prior to the enrollment. Patients will be reassured that not participating in the study will not affect the future care they receive at OSF HealthCare. The potential risks and benefits of the study will be provided and, if the patient is interested, informed consent will be obtained. If the subject withdraws consent or does not finish both pre and post evaluation, we will replace the subject with another new recruit. The subject will come to the clinic for 2 visits, a pre-magnesium visit and a post-magnesium visit. Following the completion of the pre-magnesium visit, the subject will be given 200 mg elemental magnesium daily (will be instructed to take with food at dinner) for 8 weeks. Both Visits the following study procedures will be performed: magnesium level, (International Restless Legs Syndrome) IRLS scale, Kohnen Restless Legs Syndrome Quality of Life Instrument (KRLS-QOL) scale and (Multiple Suggested Immobilization (MSI) test. The post magnesium visit will be schedule at the completion of the 8 week dose of magnesium.

| Subjective Improvement of Restless Legs Symptoms measured by the International Restless Legs Syndrome Scale (IRLS) | International Restless Leg Syndrome Scale. (IRLS) is a 10 question scale that subjects rate on a scale of 0-4; RLS can be classified as mild, moderate, severe and very severe, if the score is 0-10 (mild), 11-20 (moderate), 21-30 (severe) or 31-40 (very severe) respectively. The lower score reflects less symptom burden. Minimum score is 0 with a Maximum of 40. | Completion of Study participation at 8 weeks |
| Subjective Improvement of Restless Legs Symptoms measured by the Kohnen Kohnen Restless Legs Syndrome Quality of Life Instrument (KRLS QOL) | Kohnen Restless Legs Syndrome Quality of Life instrument (KRLS QOL) is a self-administered validated patient-reported outcome measure with 12 questions that assess the quality of life in RLS patients. Scores range from 0-60.The lower score represents less impact of RLS symptoms on quality of life. | Completion of Study participation at 8 weeks |
| Objective Improvement of Restless Legs Symptoms: Multiple Suggested Immobilization test (MSI) Score | Reduction in Multiple Suggested Immobilization test (MSI) discomfort Scores, range: 0-10, with a maximum total sum of 60 per hour. Three 1 hour trials will be conducted. Periodic limb movements during wakefulness will also be measured. Periodic limb movement index (PMLI) reflects periodic limb movements per hour. PMLI value of 0 indicates absence of limb movements and higher scores are often seen in patients with severe RLS | Completion of Study participation at 8 weeks |
| Correlation of magnesium levels with Kohnen Restless Legs Syndrome Quality of Life Instrument (KRLS) and Multiple Suggested Immobilization test (MSI) scores | Assessment of Magnesium level, lab value will be assess. Normal values range from 1.6 - 2.6 mg/dl. The rationale of measuring serum magnesium level is to analyze whether serum magnesium levels correlate with other subjective and objective RLS outcome measures |
