Probabilistic Targeting of the VIM

NCT03696420 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 1

Summary

After having included the most improved patients by DBS among those implanted in Bordeaux Hospital University, and having defined the most active plots on tremor by its prospective grading on Fahn-Tolosa-Marin (FTM) scale and accelerometry, coordinates of active plots and landmarks will be calculated on post-operative imaging. Association between landmarks and active plots coordinates will be modelled with machine-learning algorithms. The aim is to retrieve the position of the VIM on the basis of the landmarks coordinates.

Conditions

Interventions

OTHER

Coordinates of active plots and VIM landmarks calculation

Stimulation efficacy will be assessed by comparing, according to usual care, the clinical evaluation (FTM scale) with and without stimulation, and the four contacts of each electrode will be tested clinically, with an accelerometer and an electromyography to determine which one is the most active on tremor. Coordinates of the anatomical landmarks will be calculated on the pre-operative MRI and those of the active plots on the fusion between post-operative CT-scan and pre-operative MRI.
