aceThree-Dimensional Point-Cloud Learning for Patient-Specific Deep Brain Stimulation Motor Response Prediction in Parkinson Disease
Objective: To develop a patient-specific 3-dimensional (3D) point-cloud deep learning framework for predicting motor improvement after deep brain stimulation (DBS) in Parkinson's disease. Impact Statement: This study introduces an electric-field-aware point-cloud representation that preserves patient anatomy, electrode geometry, and local electric-field distributions for individualized DBS motor response prediction. Introduction: DBS response varies because of complex interactions among electrode location, anato…
Patient-specific 3D point-cloud model predicted motor improvement within 5 MDS-UPDRS-III points for 15 of 24 test cases, outperforming a voxelized CNN baseline in this fixed split.
Small fixed test set of 24 patients limits generalizability; authors state estimates do not support claims of superiority or clinical utility, and 37 patients were excluded for incomplete data.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-1202 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
