Exploring the benefits of the linear lead in deep brain stimulation.
Full description
Detailed Description:
This is a single-centre, double-blinded cross-over study comparing the 4 contact vs 8 contact electrodes of deep brain stimulation (DBS) patients.
The study will follow 2 phases.
Phase 1:
Visit 1 Screening/Baseline (T0):
As per current standard care for patients undergoing subthalamic deep brain stimulation (STN-DBS), participants will be screened 3-6 months before the surgery (T0) according to the inclusion/exclusion criteria.
Visits for standard programming of VerciseTM system between 1 to 3 months after the surgery of 10 patients will be done in an open label fashion in order to find the best program for optimization of patient motor symptoms without side effects. This will be done according to the standard of practice currently adopted at Toronto Western Hospital.
Phase 2:
Visit 1
Randomization: 4 months +/- 4weeks of the surgery, patients will be randomized to two type of stimulation:
Visit 2
Follow up visit at 6 months +/- 4 weeks of the surgery for neurological examination if required.
Visit 3 (T1):
Cross over : 7 months +/- 4 weeks after the surgery patients will be switched to the other type of stimulation . Raters and patients will be blinded to the group allocation.
Visit 4:
Follow up visit at 9 months +/- 4 weeks of the surgery for neurological examination if required.
Visit 5 (T2):
End of study visit at month 10 +/- 4 weeks after the surgery. Raters and patients will be blinded to the group allocation.
There might be unscheduled visits in case of unexpected clinical conditions (i.e. occurrence of side effects or worsening of motor conditions). Participants will be in this study for a maximum of 17 months. Throughout the whole study, participants will visit the clinic without their regular medication for PD as part of standard treatment practice. All the stimulation adjustment will be performed by the same unblinded physician using the GuideTM software provided by the company.
