Evaluation of the Effect of Pulsatile Cuts Stendo3 on Vascular Function Patients With Diabetes Type 2

The purpose of the study is to demonstrate an improvement of vascular function, and particularly dependent vasodilation flow and micro-vasculature, by STENDO for diabetic patients compared to a control period in crossover.

Action by shear stress causing vasodilation away from the microcirculation, STENDO should have a beneficial effect on vascular function in type 2 diabetics. These effects could be both treble just after the completion of a session with the device, and chronic with a potentiating effect of different sessions.

The investigators propose to study the different vascular function evaluation parameters we have, to highlight these acute and chronic changes. The investigators will also study the physical abilities to change topics and behavioral changes (spontaneous physical activity in particular) and impact on subject quality of life.

Patients will be screened during a visit V0. A collection of consent (informed consent form), clinical examination and a fasting blood test will be carried out during this visit. Laboratory tests run-in will be composed of: Cell Blood Count (CBC) platelets, renal function tests (serum electrolytes, urea and creatinine), liver function tests, fasting blood glucose levels and Lipid Profile). Measurement of blood Pressure (2 successive measurements at intervals of 5 min) and an electrocardiogram will be realized. The different information collected at enrollment will allow stratification of cardiovascular risk by reference integrators scores (ESC-SCORE (European Society of Cardiology Score) and Framingham Heart Study).

The feasibility of measures for study criteria (functional measurements and assays) will be tested fasting during this visit as the blood test.

V1 - Day 1 of the study At V1, patients have a clinical examination and a blood test fasting for the determination of endothelial parameters (Endothelial Micro Particles EMP).

Subjects will be randomized into two groups determining the sequence: STENDO then control, or control then STENDO .

Furthermore, the functional measurements will be performed at baseline, the morning after fasting for 12 hours in a room specially dedicated to the study of vascular reactivity (calm, stable temperature between 23 and 25 ° C).

When the patient has the STENDO technical, biological and functional assessments will be renewed at the end of the first session STENDO (immediately after).

For three months, patients will benefit from one-hour sessions of STENDO three times a week.

V2 30 days after inclusion +/- 1 week and V3 60 days after inclusion +/- 1 week - intermediate visits V2 and V3 intermediate visits will avoid lost sight especially during the monitoring period.

An evaluation of the quality of life (SF-36 and VAS) and physical activity (IPAQ questionnaire control and collection of eMouve) will be made for the 2 groups.

V4 at 90 days after inclusion +/- 1 week or End of 1st period V4 visit will take place in the same way that the V1 visit the day after the last session STENDO (where applicable): clinical examination, functional measurements, fasting blood test, measures of physical functions.
