Quantitative Sensory Testing (QST) in Predicting Outcomes for Spinal Cord Stimulation (SCS) for Neuropathic Pain

Thursday, November 13, 2025
3:45 PM - 4:05 PM CT
Introduction: SCS is an effective intervention for refractory pain, yet patient response remains variable. QST, a standardized psychophysical test, offers a structured method to assess somatosensory function and may identify predictors of SCS treatment response. QST involves the application of calibrated mechanical, thermal, or vibratory stimuli to assess sensory detection and pain thresholds across different fiber types (Aβ, Aδ, C). QST and SCS offer a powerful clinical and research framework to better treat refractory pain.
