Abstract
Restless legs syndrome (RLS) is defined by an irresistible need to move associated with leg paresthesia. Two additional features are essential for diagnosis: (1) worsening of symptoms at rest with temporary relief by activity, and (2) worsening of symptoms during the evening and/or during the night. The suggested immobilization test (SIT) has been developed to evaluate the presence of these criteria. This test quantifies leg movements and leg discomfort during a 1‐hour period of immobility prior to bedtime. We used the SIT to evaluate the effects of immobility on leg discomfort and leg movements experienced by 19 patients with RLS and 19 control subjects. Results show that immobility significantly worsens both leg discomfort and periodic leg movements (PLM) in patients with RLS but not in controls. Patients with RLS showed a higher leg discomfort score (32.6 ± 15.1 mm vs. 5.7 ± 7.9 mm; P < 0.00001), a greater maximum leg discomfort value (63.4 ± 27.4 mm vs. 13.7 ± 23.0 mm; P < 0.00001) and a greater PLM index (88.4 ± 62.6 vs. 10.4 ± 20.6; P < 0.00004) than control subjects. These results further validate the use of the SIT as a diagnostic and research tool for RLS and confirm the contention of the International RLS study group that RLS symptoms worsen at rest. © 2001 Movement Disorder Society.

Results show that immobility significantly worsens both leg discomfort and periodic leg movements (PLM) in patients with RLS but not in controls. Patients with RLS showed a higher leg discomfort score (32.6 ± 15.1 mm vs. 5.7 ± 7.9 mm; <i>P</i> < 0.00001), a greater maximum leg discomfort value (63.4 ± 27.4 mm vs. 13.7 ± 23.0 mm; <i>P</i> < 0.00001) and a greater PLM index (88.4 ± 62.6 vs. 10.4 ± 20.6; <i>P</i> < 0.00004) than control subjects. These results further validate the use of the SIT as a diagnostic and research tool for RLS and confirm the contention of the International RLS study group that RLS symptoms worsen at rest. © 2001 Movement Disorder Society.</p></abstract></abstractGroup></contentMeta></header></component></istex:document></istex:metadataXml><!--Version 0.6 générée le 3-12-2015--><mods version="3.6"><titleInfo lang="en"><title>Effects of immobility on sensory and motor symptoms of restless legs syndrome</title></titleInfo><titleInfo type="abbreviated" lang="en"><title>RLS Sensory and Motor Symptoms</title></titleInfo><titleInfo type="alternative" contentType="CDATA" lang="en"><title>Effects of immobility on sensory and motor symptoms of restless legs syndrome</title></titleInfo><name type="personal"><namePart type="given">Martin</namePart><namePart type="family">Michaud</namePart><namePart type="termsOfAddress">MSc</namePart><affiliation>Centre d'étude du sommeil et des rythmes biologiques, Hôpital du Sacré‐Cœur, Montréal, Canada</affiliation><affiliation>Département de Psychiatrie, Faculté de Médecine, Université de Montréal, Canada</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Gilles</namePart><namePart type="family">Lavigne</namePart><namePart type="termsOfAddress">DMD, MSc</namePart><affiliation>Centre d'étude du sommeil et des rythmes biologiques, Hôpital du Sacré‐Cœur, Montréal, Canada</affiliation><affiliation>Faculté de Médecine Dentaire, Université de Montréal, Canada</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Alex</namePart><namePart type="family">Desautels</namePart><namePart type="termsOfAddress">MSc</namePart><affiliation>Centre d'étude du sommeil et des rythmes biologiques, Hôpital du Sacré‐Cœur, Montréal, Canada</affiliation><affiliation>Douglas Hospital et Centre de recherche en Sciences Neurologiques, Université de Montréal, Canada</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Gaétan</namePart><namePart type="family">Poirier</namePart><namePart type="termsOfAddress">MSc</namePart><affiliation>Centre d'étude du sommeil et des rythmes biologiques, Hôpital du Sacré‐Cœur, Montréal, Canada</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">Jacques</namePart><namePart type="family">Montplaisir</namePart><namePart type="termsOfAddress">MD, PhD</namePart><affiliation>Centre d'étude du sommeil et des rythmes biologiques, Hôpital du Sacré‐Cœur, Montréal, Canada</affiliation><affiliation>Département de Psychiatrie, Faculté de Médecine, Université de Montréal, Canada</affiliation><description>Correspondence: Centre d'étude du sommeil et des rythmes biologiques, Hôpital du Sacré‐Coeur de Montréal, 5400 Blvd. Gouin Ouest, Montréal, Québec, Canada H4J 1C5</description><role><roleTerm type="text">author</roleTerm></role></name><typeOfResource>text</typeOfResource><genre authority="originalCategForm">article</genre><originInfo><publisher>John Wiley & Sons, Inc.</publisher><place><placeTerm type="text">New York</placeTerm></place><dateIssued encoding="w3cdtf">2002-01</dateIssued><dateCaptured encoding="w3cdtf">2001-02-20</dateCaptured><dateValid encoding="w3cdtf">2001-06-26</dateValid><copyrightDate encoding="w3cdtf">2002</copyrightDate></originInfo><language><languageTerm type="code" authority="rfc3066">en</languageTerm><languageTerm type="code" authority="iso639-2b">eng</languageTerm></language><physicalDescription><internetMediaType>text/html</internetMediaType><extent unit="figures">1</extent><extent unit="tables">1</extent><extent unit="references">10</extent><extent unit="words">2320</extent></physicalDescription><abstract lang="en">Restless legs syndrome (RLS) is defined by an irresistible need to move associated with leg paresthesia. Two additional features are essential for diagnosis: (1) worsening of symptoms at rest with temporary relief by activity, and (2) worsening of symptoms during the evening and/or during the night. The suggested immobilization test (SIT) has been developed to evaluate the presence of these criteria. This test quantifies leg movements and leg discomfort during a 1‐hour period of immobility prior to bedtime. We used the SIT to evaluate the effects of immobility on leg discomfort and leg movements experienced by 19 patients with RLS and 19 control subjects. Results show that immobility significantly worsens both leg discomfort and periodic leg movements (PLM) in patients with RLS but not in controls. Patients with RLS showed a higher leg discomfort score (32.6 ± 15.1 mm vs. 5.7 ± 7.9 mm; P < 0.00001), a greater maximum leg discomfort value (63.4 ± 27.4 mm vs. 13.7 ± 23.0 mm; P < 0.00001) and a greater PLM index (88.4 ± 62.6 vs. 10.4 ± 20.6; P < 0.00004) than control subjects. These results further validate the use of the SIT as a diagnostic and research tool for RLS and confirm the contention of the International RLS study group that RLS symptoms worsen at rest. © 2001 Movement Disorder Society.</abstract><subject lang="en"><genre>Keywords</genre><topic>restless legs syndrome</topic><topic>suggested immobilization test</topic><topic>periodic leg movements</topic><topic>visual analog scale</topic><topic>immobility</topic><topic>sensory report</topic></subject><relatedItem type="host"><titleInfo><title>Movement Disorders</title></titleInfo><titleInfo type="abbreviated"><title>Mov.
