    The study analyzed 17 patients with isolated generalized dystonia undergoing GPi-DBS to assess electrode placement and treatment outcomes.

  • 2

    Significant improvements were observed in postoperative BFMDRS-M and BFMDRS-D scores, indicating enhanced motor function after GPi-DBS.

  • 3

    Electrode positions closer to the ventral GPi correlated with better improvement rates in motor function, emphasizing precise targeting.

  • 4

    Preoperative anxiety levels, as measured by HAMA, were identified as an independent predictor of poor motor outcomes post-surgery.

  • 5

    The findings support the importance of accurate electrode placement and preoperative anxiety assessment in optimizing DBS outcomes for IGD patients.
