OBJECTIVES To assess the frequency, impact, and medical response to the restless legs syndrome (RLS) in a large multi-national primary care population. METHOD Questionnaire surveys of matched patients and primary care physicians (PCPs) in five modern industrialized western countries. RESULTS An RLS screening questionnaire was completed by 23,052 patients: 2223 (9.6%) reported weekly RLS sym...

In this paper, we propose a new pipelining extended Givens Rotation Recursive Least Square (PEGR-RLS) architecture using look-ahead technique. The square-root-free forms of QRD-RLS are also difficult to pipeline. The PEGR-RLS algorithm (referred to as Scaled Tangent Rotation, STAR-RLS) is designed such that fine-grain pipelining can be accomplished with little hardware overhead. Similar to STAR...

BACKGROUND In the past few decades, much has been learned about the pathophysiology of restless legs syndrome (RLS). Investigators have studied neuropathology, imaging, electrophysiology, and genetics of RLS, identifying brain regions and biological systems affected in RLS. This manuscript will review RLS pathophysiology literature, examining the RLS state through consideration of the neuroanat...

STUDY OBJECTIVES To investigate the prevalence of restless legs syndrome (RLS) in fibromyalgia (FM) and determine the presence and amount of sleep disruption in FM patients with RLS. RLS and FM have been associated in uncontrolled studies using a variety of RLS definitions. We explored this relationship using a cross-sectional study design. METHODS FM cases that met the American College of Rh...

BACKGROUND Monitoring retinal oxygenation is of primary importance in detecting the presence of some common eye diseases. To improve the estimation of oxygen tension in retinal vessels, regularized least-squares (RLS) method was shown to be very effective compared with the conventional least-squares (LS) estimation. In this study, we propose an accelerated RLS estimation method for the problem ...

Restless legs syndrome (RLS) is a common neurological disorder that is characterized by an urge to move the legs (or arms), usually accompanied by uncomfortable and bothersome sensations in the affected limbs. The prevalence of RLS ranges from 7.2% to 11.5% in the general population, and its symptoms are frequent or severe enough to require medical treatment by approximately 3% of the populatio...

OBJECTIVE This study was cross sectional survey conducted to find the prevalence of Restless legs syndrome (RLS) in end stage renal disease (ESRD) patients on haemodialysis (HD). METHODS Data were obtained from 250 patients on chronic maintenance HD. To assess the prevalence of RLS, Clinical diagnostic criteria for RLS was used which is established by the International RLS Study Group. RESU...

INTRODUCTION Restless legs syndrome (RLS) affects 5-15% of adults, but is often unrecognized and consequently misdiagnosed. The International Restless Legs Scale (IRLS) has been developed and validated to assess the severity of RLS. Currently, the most common treatment for RLS is levodopa, but this may lead to augmentation of symptoms. Pramipexole has been developed as an alternative treatment ...

STUDY OBJECTIVES To determine the frequency of nocturnal eating (NE) and sleep related eating disorder (SRED) in restless legs syndrome (RLS) versus psychophysiological insomnia (INS), and the relationship of these conditions with dopaminergic and sedative-hypnotic medications. DESIGN Prospective case series. SETTING Sleep disorders center. PATIENTS Newly diagnosed RLS or INS. INTERVENT...

In this paper, a new computationally efficient algorithm for recursive least-squares (RLS) filtering is presented. The proposed Split RLS algorithm can perform the approximated RLS with O ( N ) complexity for signals having no special data structure t o be exploited. Our performance analysis shows that the estimation bias will be small when the input data are less correlated. We also show that ...
