The Ducest Neurostimulator V opens up new minimally invasive possibilities for the additive therapy of peripheral arterial occlusive disease (PAD) and chronic pain. Through intermittent stimulation using a stimulation needle applied to the ear, Ducest neurostimulation therapy involves the brain stem in the treatment. The autonomic nervous system is modulated and positively influenced via an afferent nerve plexus located at the triangular fossa, which leads via C2 and C3 to the nucleus tractus solitarii in the brain stem. This results in higher parasympathetic activity, better blood flow in the capillaries and an increase in transcutaneous oxygen partial pressure.

When the stimulation needle is connected to the Ducest neurostimulator, the device is activated and starts stimulating at 1 Hertz. After 40 minutes of stimulation, there is a 20-minute break. The alternation of both phases continues automatically for 21 days. The device is fixed to the shoulder and the current intensity is set so that it is barely perceptible to the patient. In later therapy phases, the impulses are often no longer perceived subjectively.

Therapy with the Ducest Neurostimulator V increases the chances of PAD patients walking longer distances and reducing the sensation of pain. Ducest neurostimulation therapy is a new option for the complementary and patient-friendly treatment of PAD and other chronic pain disorders.
