Clinical Trials

clinical trials

While the RLS Foundation does not conduct clinical trials, we do list clinical trial opportunities below and in our quarterly member newsletter, NightWalkers. If you are interested in participating in a study, please scroll down to contact the researcher listed below. Clinical trials are research studies that enlist volunteers to investigate specific health questions. When carefully conducted, they are the fastest and safest way to find treatments that actually work for people. When you volunteer for a restless legs syndrome (RLS) clinical trial, you explore emerging treatment options for yourself while actively contributing to the advancement of RLS research. If you are a researcher who would like to include your study in our listings, please contact us at All studies must be approved by the Institutional Review Board (IRB) to qualify. There is no charge to publish a listing.

The Emotional State in RLS

RLS is associated with emotional distress and depression. Researchers at Yale are conducting a study that looks at this emotional stress and depression. The study is entirely an on-line questionnaire study. You will not need to talk to anyone to complete this study and it is completely anonymous. There is no way for the researchers or anyone to determine your identity even after you have completed the questionnaires. The first set of questions are to determine if you are eligible. We are looking to study primary RLS, that is RLS that occurs in the absence of diseases like, Parkinson disease, multiple sclerosis, severe neuropathy, end stage renal disease, schizophrenia, terminal cancer, and others. The questionnaires will take about 20 minutes to complete.

We also need a control group, so we ask that you identify someone without RLS that also does not have conditions, such as the ones mentioned above. For controls filling out the questionnaires will take under 10 minutes.
