The electrodes that were developed initially were unipolar, and the shortcomings were apparent through its limited field of paresthesia and application. The SCS hardware consists of an electrode lead, an extension cable, a pulse generator, and a programmer. Recently, the outcomes of SCS have improved significantly and have become a widely accepted form of therapy for chronic intractable neuropathic pain. It is strategically aimed to replace the unpleasant sensory experience of pain with a more pleasing tingling sensation referred to as parasthesia. Therefore, the term dorsal column stimulation was replaced with SCS. Low-level electrical impulses, delivered directly into the spinal cord through the SCS that is inserted in the epidural space, interfere with the direct transmission of pain signals traveling along the spinal cord to the brain. However, it has recently been proven that applying an electrical field to the dorsal epidural space might activate a larger number of neural structures. In 1967, Shealy first inserted the dorsal column stimulator into patients suffering from cancer pain. The technique is believed to inhibit chronic pain by stimulating the large diameter afferent nerve fibers in the spinal cord, which is based on the gate control theory of pain proposed by Melzack and Wall. It has been used for approximately four decades in treating chronic neuropathic pains that have been refractory to other conventional treatments. Neuromodulation with Spinal cord stimulation (SCS) is one of the most exciting developments in chronic pain management. Chronic pain is a leading cause for physical and emotional suffering, familial and social disruptions, disability, and work absenteeism.
