Why it matters
Spinal fusion surgery often fails to provide relief even when the physical surgery is 'successful,' and doctors have never known why. This study identifies that the speed of a patient's 'alpha' brain waves is a trait-like signature that accurately forecasts whether a patient's nervous system is capable of letting go of chronic pain after the operation.
From the abstract
Objective Postoperative pain outcomes following spinal fusion surgery remain difficult to predict, as structural and surgical indicators alone offer limited insight into who will experience meaningful relief. A substantial proportion of patients continue to report persistent pain after surgery, underscoring the need for objective markers that can help identify those at risk of poor recovery. Peak alpha frequency (PAF) has emerged as a promising trait-like neural signature of pain sensitivity in
