The aim is to explore the link between electrode placement, volume of tissue activated, and treatment efficacy in isolated generalized dystonia.
Enrolled 17 patients with isolated generalized dystonia receiving bilateral GPi-DBS at Beijing Tiantan Hospital.
Utilized preoperative MRI and postoperative CT for accurate electrode localization.
Evaluated clinical efficacy using multiple scales including BFMDRS for dystonia assessment.
Postoperative BFMDRS-M and BFMDRS-D scores significantly decreased compared to preoperative scores (P < 0.001).
Significant correlation found between electrode position and BFMDRS-M improvement rate (left side: P = 0.004; right side: P = 0.041).
Preoperative HAMA score identified as an independent predictor of poor motor outcomes (P = 0.0189).
