About the trial
What the trial wants to find out
Restless leg syndrome (RLS) is not uncommon and can also affect people's health and quality of life. Mainly, RLS is diagnosed based on clinical criteria subjectively. Sometimes it is difficult to differentiate between RLS and mimickers, especially in patients with comorbidities such as diabetes or parkinson's disease. We believe that using objective tests would facilitate accuracy in RLS diagnosis, which leads to proper management of patients.
The group in the trial
- Clinical diagnosed restless leg syndromeTreatment being tested
Participants with appointment of sleep test and clinical diagnosed restless leg syndrome according to International Restless Legs Syndrome Study Group (IRLSSG) are reruited and undergo a suggested immobilization test before the standard polysomnographic study.
