Spinal Cord Stimulation (SCS) is the single most dominant application within the electrical therapy domain, largely due to its proven efficacy in managing chronic, intractable pain, especially neuropathic pain that has failed to respond to conventional treatments. This includes conditions like Failed Back Surgery Syndrome (FBSS), Complex Regional Pain Syndrome (CRPS), and severe nerve pain.

The procedure involves placing thin leads (electrodes) in the epidural space near the spinal cord. A small, implanted pulse generator delivers mild electrical pulses that intercept the pain signals travelling from the nerves to the brain. According to the "Gate Control Theory," the electrical pulses replace the painful sensation with a tingling feeling (paresthesia), or, with newer systems, deliver sub-perception therapy where the stimulation is not felt at all.

The initial success of SCS systems is often confirmed through a temporary "trial phase," allowing patients to test the therapy's effectiveness before committing to a permanent implant. This minimal-risk, customizable, and reversible approach makes it a preferred, non-opioid alternative for long-term chronic pain relief.

FAQ Q: What is the main neurological principle behind how Spinal Cord Stimulation (SCS) works? A: SCS works based on the Gate Control Theory, where electrical impulses are used to block or modulate pain signals before they reach the brain.

Q: What is the benefit of the "trial phase" often used with SCS therapy? A: The trial phase allows the patient to test the device's effectiveness using temporary electrodes for a few days, ensuring the therapy is beneficial before they commit to a permanent implant.
