Clinical Studies
Electrical calf muscle stimulation with Veinoplus device in postoperative venous thromboembolism prevention
80 patients undergoing high-risk surgery under general anesthesia were randomized to one of two groups: Main (addition of VEINOPLUS) and Control (no calf muscle stimulation).
Electrical calf muscle stimulation (EMS) with the VEINOPLUS device was performed for not less than 5 periods of 20 minutes per day (total > 100 minutes) in the main group.
The incidence of post of DVT was 2.5% in the main group and 25% in the control group.
The efficacy of a new stimulation technology to increase venous flow and prevent venous stasis
Using neuromuscular electrostimulation to substantially increase venous velocity (up to 10X) and total venous flow (up to 12X).
With a venous velocity and venous flow this high, it is unlikely that blood will clot. Stimulation rates of 2 and 8 beats per min. were used. The clinical endpoint of acute post-op DVT will be addressed in the following reference.
Electromuscular stimulation with VEINOPLUS® for the treatment of chronic venous edema
Chronic painful limb edema of venous etiology was addressed by Bogachev VY., et al. All patients were treated with the Veinoplus neuromuscular stimulator.
during 30 days: 3 20-minute sessions per day for 10 days, then 2 sessions per day for 10 days, then 1 session per day for 10 days. Results showed either partial or complete.
Resolution of leg and ankle edema in 94% of patients. The number of painful limbs decreased by 57%, and the venous clinical severity score decreased from 8.3 to 3.8 (p<0.001). QOL was significantly improved and venous refill time was also significantly improved.
Electrical calf muscle stimulation in patients with post-thrombotic syndrome and residual venous obstruction after anticoagulation therapy
Post-Thrombotic venous disease and recurrent venous thrombosis are serious clinical problems. Ryzhkin VV et al. studied the impact of EMS with the Veinoplus device on recurrent DVT following a full course of anticoagulation for Acute lower extremity DVT.
They followed thrombus resolution over a 12-month follow-up period with venous duplex imaging as well as post-thrombotic discomfort.
They randomized 60 patients who completed a full course of anticoagulation for acute DVT, 30 who received EMS (Main group), and 30 who had standard care without EMS.
At 12-month follow-up, the frequency of recurrent venous thrombosis was 0 in the Main group and 7 (23%) in the Controls (p<0.001). There was also significant thrombus resolution on ultrasound in the Main group, along with a reduction in symptoms of post-thrombotic venous disease.
Electrical muscle stimulation with Veinoplus® device in the treatment of venous ulcers
Electrical muscle stimulation (EMS) with the Veinoplus device for the treatment of Venous Ulcers was studied by Bogachev VY et al.
They randomized 60 legs with an active venous ulcer to the Main group, which underwent EMS at least 3 times per day in addition to standard of care, or to the Control group, which received standard of care alone.
At day 90 pain was significantly reduced in the main group, ankle circumference (swelling) was significantly reduced in the main group as was the Venous Clinical Severity Score.
Healing rates were significantly higher in the main group, with 87% healed in the main group and 60% healed in the control group.
The Effectiveness of Calf MuscleElectrostimulation on Vascular Perfusion and Walking Capacity
Using variable frequency calf muscle electrostimulation (1-250 Hz, 1 hr/day, 12 weeks) to improve arterial perfusion and walking capacity in diabetic PAD patients who cannot tolerate traditional exercise.
Walking distance improved 41% and ABPI increased significantly (P=.001), likely driven by collateral vessel development at higher stimulation frequencies. No control group was used.
