Spinal Cord Stimulation ($\text{SCS}$) is a form of neuromodulation therapy used primarily in the United Kingdom for patients with severe, chronic, intractable pain syndromes—such as failed back surgery syndrome or complex regional pain syndrome—who have not responded adequately to conservative treatments, pharmacological regimens, or standard interventional procedures.

The technology involves the surgical implantation of an electrode array (lead) into the epidural space near the spinal cord and a pulse generator (IPG) under the skin, which delivers mild electrical impulses to interfere with pain signals traveling to the brain, offering a non-opioid alternative for pain relief.

Recent technical innovations have significantly advanced the utility of $\text{SCS}$ systems. Traditional tonic stimulation is being supplemented by newer waveforms, including Burst and High-Frequency ($10 \text{ kHz}$) stimulation, which often provide superior pain relief, especially for patients with limb or axial pain, sometimes without the paresthesia (tingling sensation) associated with older systems. The selection of patients is highly rigorous, involving a mandatory psychological evaluation and a temporary trial phase where external leads are placed for several days to determine efficacy before permanent implantation. This structured assessment is crucial for ensuring cost-effectiveness and appropriate patient selection within the National Health Service ($\text{NHS}$) framework. Furthermore, the longevity and size of the implantable pulse generators have improved dramatically with rechargeable batteries and smaller form factors. The long-term success of $\text{SCS}$ relies not just on the hardware but on the comprehensive multidisciplinary approach involving pain specialists, physiotherapists, and nurses to manage expectations, optimize programming, and integrate the system into a broader rehabilitation strategy.
