Several studies have shown that spinal cord stimulation (SCS) is a very effective way to treat chronic pain when other treatments, such as medications and surgery, have not been effective. This study examines the mechanics, clinical results, and particular indications of the three main SCS protocols: burst, high-frequency, and tonic stimulation. Based on the gate control principle, tonic stimulation has been applied extensively but has several drawbacks, such as decreasing effectiveness with time. A superior treatment option for back and leg pain is high-frequency stimulation, which lessens discomfort without producing paresthesia. By modifying brain activity, especially in the anterior cingulate cortex, burst stimulation targets the affective components of pain and improves patients’ quality of life. Even with SCS’s advances, problems like tolerance and decreased long-term efficacy still exist. Closed-loop and data-driven intelligent SCS systems are among the future directions that will usher in a new era in chronic pain management by providing real-time modifications and individualized treatment programs.
