[Neuromodulation--controlled analgesia. Criteria for long efficiency]

Area of Science:

• Neurosurgery
• Pain Management
• Neuromodulation

Background:

• Chronic pain management has shifted from destructive procedures to neuromodulation techniques over the past three decades.
• Surgical neuromodulation includes electric stimulation (ES) and intrathecal drug delivery systems.
• Neurostimulation is increasingly utilized for non-cancer pain syndromes.

Observation:

• Destructive surgical methods for chronic pain have largely been replaced by neuromodulation.
• Electric stimulation (ES) of nerves, spinal cord, and brain are key neurostimulation techniques.
• Intrathecal drug delivery via programmed pumps is another neuromodulation approach.

Findings:

• Negative outcomes in neuromodulation were primarily observed in patients with significant deafferentation.
• Postoperative testing of electric stimulation (ES) is a critical predictor of effectiveness for spinal cord stimulation (SCS).
• Contrary to some beliefs, chronic ES demonstrated positive outcomes in a 3-year follow-up for several patients.

Implications:

• Neurostimulation offers high efficiency and minimal invasiveness for treating neurogenic pain.
• The technique has a low complication rate and potential for improved long-term effectiveness.
• Neurostimulation may serve as an early surgical intervention for neurogenic pain syndrome.
