To date, however, this technology has never been evaluated in the peripheral circulation.The magnetic susceptibility of iron in the circulating blood and the ionic currents in the blood stream generate a very weak induced magnetic current, which can be detected by the micro-sensor of the prototype investigators wish to study.Proving the validity of this prototype would make it a new diagnostic and even prognostic tool, non-invasive, less costly and more accessible than Doppler for screening peripheral arterial disease., conditionsModule conditions: Lower Extremity Artery Disease, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: NA, interventionModel: SINGLE_GROUP, primaryPurpose: DIAGNOSTIC, maskingInfo masking: NONE, enrollmentInfo count: 70, type: ESTIMATED, armsInterventionsModule interventions name: Evaluation by magnetic sensor, outcomesModule primaryOutcomes measure: Correlation of the two curve amplitudes (y) versus time (x) between the signal recording obtained by the CapMagic prototype on the radial artery and the pulsed echo-Doppler recording on the radial artery, secondaryOutcomes measure: Correlations of the two curve amplitudes (y) versus time (x) between the signal recording obtained by the CapMagic prototype and the pulsed echo-Doppler recording, measured on the plantar artery on one side and on the pulpal artery on the other, secondaryOutcomes measure: Correlation of the Pulsatility index (or Gosling Pulsatility index) between the signal recording obtained by the CapMagic prototype and the pulsed echo-Doppler recording, secondaryOutcomes measure: Correlation of the Systolic rise time (SRT) between the signal recording obtained by the CapMagic prototype and the pulsed echo-Doppler recording, secondaryOutcomes measure: Correlation of the Systolic peak between the signal recording obtained by the CapMagic prototype and the pulsed echo-Doppler recording, secondaryOutcomes measure: Correlation of the Type of flow according to Saint-Bonnet classification between the signal recording obtained by the CapMagic prototype and the pulsed echo-Doppler recording, secondaryOutcomes measure: Correlation of Presence of critical ischemia measured by the CapMagic prototype and the pulsed echo-Doppler recording, eligibilityModule sex: ALL, minimumAge: 18 Years, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: University Hospital Center, status: RECRUITING, city: Montpellier, country: France, contacts name: Gudrun BOGE, MD, role: CONTACT, phone: 467336279, phoneExt: 33, email: g-boge@chu-montpellier.fr, contacts name: Gudrun BOGE, role: PRINCIPAL_INVESTIGATOR, geoPoint lat: 43.61092, lon: 3.87723, hasResults: False
