About this study

Official title: Investigation of the Arterial Effects of the Veinoplus(r) Stimlator Device.

Stimulation of arterial inflow to the lower limb is important to obtain functional improvement in peripheral artery diseased (PAD) patients with claudication. The clinical effect of muscle stimulation to increase arterial inflow and the direct evaluation of the regional blood flow impairment (RBFI) in the area of stimulation, have not been evaluated in PAD patients.

Fifteen adult patients with stable arterial claudication will participate. Recruitment will be performed among patients referred for exercise oxymetry (treadmill: 3.2km.h-1, 10% slope) After two minutes of rest, the gastrocnemius will be stimulated for 20 minutes at an increasing frequency rate with 5 min steps (1 Hz, 1.25 Hz, 1.5 Hz and 1.75 Hz) on the most symptomatic side.

The investigators record the tcpo2 value, arterial blood inflow with ultrasound of the femoral artery, and near infra-red spectrometry (NIRS) on both sides.

Patients will be instructed to report eventual contraction-induced pain in the stimulated calf.

Read the detailed description

Investigations are conducted in an air-conditioned 22+/-2 °C room, with the patient comfortably seated on an armchair.

Measured ware started at rest and performed throughout the period pf stimulation and for 10 minutes after the end of the stimulation

Muscle stimulation:

We apply a series of 20 minutes of stimulation with the Veinoplus® device. The device delivers a stimulation of incremental rate with 5 minutes intervals, with 1 Hz, 1.25 Hz, 1.5 Hz and 1.75 Hz and then stops automatically.

Ultrasound measurements The Diameter of the superficial femoral artery was measured at rest on both sides before each study. The VTI of 3 cardiac cycles (three peaks systolic velocity) will be measured by duplex ultrasound imaging, to calculate the arterial inflow to the leg. Results will be expressed in l /min.

Tcpo2 recording TcpO2 is measured at the chest and on both calves with TCM 400 (Radiometer, DK). Results are expressed in DROP index(mmHg) values.

Near Infra-red spectroscopy (NIRS) We use the ARTinis NIRS device (ARTinis; NL) to estimate tissue saturation (StO2) on both gastrocnemius muscles of the leg.

Systemic hemodynamic parameters

Systemic and diastolic arterial pressures and heart rate are recorded every two minutes using Dinamap V100 (GE france).

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing electrical muscle stimulation in people with Peripheral Artery Disease, run by University Hospital, Angers at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

arterial inflow (time frame: during stimulation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01592812, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Mar 2013.
