An Electrical Stimulator to Suppress the Nervous Pain in Diabetic Neuropathic Patients

Abstract

Peripheral neuropathy is an acute disorder in diabetic patients who are suffering a very agonized pain in their peripheral nerves. Symptomatic relief can be achieved by some analgesic pain killers. One of the best approaches is using an electrical stimulation method where the sensory nerve fibers get excited by the application of pulsed currents at the site of pain. This could block the pain signals from reaching the brain, followed either by the pain gate theory or opioid mechanism. This study primarily focuses the feedback principle where the stimulus is given with respective to the patient’s skin intensity to avoid skin burning in therapy. The opioid mechanism has been proved scientifically that it provides long-lasting pain relief even after the stimulation. This paper documents the design and operation of feedback system which provide a constant output by varying the width of pulses. Thereby, the patient’s pain as well as the sufferings of skin reactions upon stimulus is reduced. As this electrical nerve stimulation strategy is a simple, safe, non-pharmacological, cost-effective it proves to be a better alternative for pain relief
