SC stimulation is used to monitor what during surgical procedures?

Spinal cord stimulation (SC stimulation) is primarily utilized to assess the function of the posterior columns of the spinal cord, which are responsible for proprioception and vibration sensation. During surgical procedures, particularly those involving the spine or surrounding areas, monitoring this specific function is crucial to ensure that sensory pathways remain intact and to prevent postoperative complications such as loss of sensation or motor function.

Thus, the correct focus of assessment is the monitoring of the posterior spinal cord function, as it allows for real-time feedback on the integrity of these critical pathways. This is particularly relevant in surgeries that carry a risk of spinal cord injury, enabling surgeons to make informed decisions to safeguard the patient's neurological outcomes.
