Accurate subthalamic beta activity could guide deep brain stimulation programming in Parkinson's disease, but bipolar recordings complicate contact selection. In 39 patients, we validated three methods to estimate pseudo-monopolar beta power. Distance-weighted methods (Euclidean, Strelow) agreed consistently with the externalized "ground-truth" beta distribution. Maximal beta power across 20s windows was more stable in ring than in directional channels. Beta-contacts from all methods aligned with clinically active stimulation contacts one year after surgery.
