Brief Summary:
Deep Brain Stimulation represents the golden standard for surgical treatment of Parkinson disease (PD), but it is not optimally effective for controlling every motor sign and adverse events are not so infrequent Therefore, other approaches should be considered.We identified the motor cortex as a possible candidate and therefore we propose a double-blind randomized prospective study in 20 Parkinson patients in order:
* to test the efficacy of epidural motor cortex stimulation in Parkinson disease (primary endpoint: UPDRS III at 12 months at the end of the cross-over)
* to find out optimal electrode position and optimal stimulation parameters
* to test the efficacy of epidural motor cortex stimulation in Parkinson disease (primary endpoint: UPDRS III at 12 months at the end of the cross-over)
* to find out optimal electrode position and optimal stimulation parameters
Detailed Description:
20 Parkinsonian patients will be enrolled. After implantation of a bilateral strip electrode (Resume, Medtronic) over the motor cortex, after setting of optimal stimulation parameters, and after implantation of a neurostimulator, Medtronic, the patient will be randomly assigned to group A (Motor cortex stimulation on) or to group B ( sham stimulation) for 6 months. Randomization will be based on the output of a program based on a random number generation function that will output a 0 or 1 with a 50% chance of having a 1.
At the 6 months visit, a cross-over is scheduled: group A will receive sham stimulation and group B will receive stimulation of the motor cortex for the next 6 months. In group A, the stimulation of the motor cortex will be resumed before the end of the 6 month sham stimulation, when the clinical status of the patient will come back to the status quo ante (UPDRS score equal to baseline pre-implant score).
Both the patients and the evaluating neurologists and neuropsychologists will be blind; only the neurosurgeon will know the state of the stimulator (on or off) and the position and parameters of MCS.
At 12 months, all the patients will be programmed as stimulation on and followed up for further 18 months. At 30 months visit, the clinical evaluation will be performed in on stim-on med, on stim-off med conditions; then the stimulator will be switched off for 1 month and the clinical evaluation will be repeated in off stim-off med and off stim-on med conditions.
The primary endpoint will be the UPDRS III at 12 months (end of the cross over), and subsequently at 18 and 30 months. We will compare the clinical results with the precise site of the stimulating electrodes and we will try to correlate the clinical results with the amount of inhibition induced by motor cortex stimulation.
At the 6 months visit, a cross-over is scheduled: group A will receive sham stimulation and group B will receive stimulation of the motor cortex for the next 6 months. In group A, the stimulation of the motor cortex will be resumed before the end of the 6 month sham stimulation, when the clinical status of the patient will come back to the status quo ante (UPDRS score equal to baseline pre-implant score).
