Attacks most often occur in the fingers, but may occur in other extremities as well.\n\nDESIGN NARRATIVE:\n\nRandomized. Patients were assigned to one of four treatment groups: slow release Nifedipine, a calcium channel blocker; pill placebo; temperature biofeedback; or electromyograph biofeedback from the frontalis muscle. The primary endpoint was reduction in number of vasospastic attacks. Other endpoints included: other measures of Raynaud's attacks including frequency, severity, duration, response to laboratory-based cold challenge, and quality of life."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "maximumAge"=>"75 years", "minimumAge"=>"18 years", "healthyVolunteers"=>false, "eligibilityCriteria"=>"Men and women with documented primary or secondary Raynaud's syndrome."}, "identificationModule"=>{"nctId"=>"NCT00000530", "briefTitle"=>"Raynaud's Treatment Study (RTS)", "organization"=>{"class"=>"NIH", "fullName"=>"National Heart, Lung, and Blood Institute (NHLBI)"}, "orgStudyIdInfo"=>{"id"=>"73"}}, "armsInterventionsModule"=>{"interventions"=>[{"name"=>"nifedipine", "type"=>"DRUG"}, {"name"=>"biofeedback (psychology)", "type"=>"BEHAVIORAL"}, {"name"=>"electromyography", "type"=>"PROCEDURE"}]}, "contactsLocationsModule"=>{"overallOfficials"=>[{"name"=>"Bruce Thompson", "affiliation"=>"Clinical Trials & Surveys Corp (C-TASC)"}]}, "sponsorCollaboratorsModule"=>{"leadSponsor"=>{"name"=>"National Heart, Lung, and Blood Institute (NHLBI)", "class"=>"NIH"}}}}
