RLS symptoms (urge to move the leg and leg paresthesia) are primarily observed during wakefulness, especially at rest, in the evening, and\u002For during the night. During the test, the patient remains in a bed (or a reclining chair), at a 45° angle with legs outstretched. Originally, the SIT only quantified leg motor activity. Since 2002, it also includes the assessment of leg discomfort, which is estimated by the patient every 5 min, on a 100-mm horizontal visual analogue scale. Leg movements are quantified using surface electromyography (EMG) from bilateral anterior tibialis muscles. Using these pathological thresholds, the clinical RLS\u002FWED diagnosis is correctly predicted in 88% of subjects with a sensitivity of 82% and a specificity of 100%.
