Restless Leg Syndrome
Síndrome de Piernas Inquietas
What it means
Restless legs syndrome (RLS) causes a powerful urge to move the legs. The legs become uncomfortable when a person is lying down or sitting; some people describe it as a creeping, crawling, tingling, or burning sensation. Moving makes the legs feel better, but not for long, and RLS can make it hard to fall asleep and stay asleep. The National Institute of Neurological Disorders and Stroke (NINDS) describes RLS, also known as Willis-Ekbom disease, as a neurological condition and a sleep disorder triggered by resting and attempting to sleep. MedlinePlus says that in most cases there is no known cause; in other cases RLS is caused by a disease or condition, such as anemia or pregnancy. In Spanish it is síndrome de piernas inquietas.
Restless Leg Syndrome in Spanish
- Spanish term
- Síndrome de Piernas Inquietas
- Gender and article
- masculine: el síndrome de piernas inquietas
- Pronunciation
- SEEN-droh-meh deh PYEHR-nahs een-KYEH-tahs
| Other Spanish terms | Where it is used | Note |
|---|---|---|
| síndrome de las piernas inquietas | General | Form with the article las, used as the title of the MedlinePlus en español topic page and encyclopedia article. |
| SPI | General | Spanish abbreviation used by the Spanish-language NINDS page. |
| enfermedad de Willis-Ekbom | General | The Spanish-language NINDS page says the syndrome is also known by this name; the MedlinePlus en español encyclopedia lists it among its alternative names. |
The sources write this name in lower case: síndrome de piernas inquietas. Síndrome takes the masculine article, as in el síndrome de piernas inquietas. MedlinePlus en español titles both its topic page and its encyclopedia article síndrome de las piernas inquietas, with the article las, and writes both that form and síndrome de piernas inquietas in the text. NINDS says the syndrome is also known as enfermedad de Willis-Ekbom.
The abbreviation depends on the publisher: the Spanish-language NINDS page writes SPI, while the MedlinePlus en español encyclopedia keeps the English abbreviation RLS, explaining that it comes from the English name (por sus siglas en inglés). Words these pages use for the sensations are hormigueo (tingling), ardor (burning) and picazón (itching). The urge to move is described as un deseo irresistible de mover sus piernas by MedlinePlus en español and as una necesidad imperiosa de mover las piernas by NINDS.

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
