The investigators will seek to enroll people with Parkinson's disease (PD) who have been approved for deep brain stimulation surgery (DBS) as part of their routine clinical

The investigators will seek to enroll a cohort of age- and sex-matched healthy individuals to act as a control group. This group will NOT undergo DBS surgery

During DBS surgery, tasks will be administered via a tablet PC or mounted monitor, and the subject may hold a response box, joystick, or dynamometer to record responses. During task periods, sensory stimuli will be delivered to the participant, who may be asked to perform a motor behavior in response. Stimuli will consist of audiovisual cues presented on a computer screen, vibration applied to specific parts of the body via a tactor, mild electrical pulses delivered through the skin of specific parts of the body via the attached EMG electrodes, and/or a movement of the arm or joint. Motor responses will consist of simple movements such as finger-tapping or hand-opening, or use of a joystick or dynamometer to move a computer cursor on the screen. Participants may be asked to respond only to a particular sensory stimulus and ignore others, in order to modulate the relevance of each stimulus to the task.

Intraoperative Behavioral Testing

Behavioral Testing

Zachary Irwin, PhD

The investigators are investigating the brain activity associated with sensory information in movement disorders in order to improve treatment of these symptoms beyond what is currently available.

The purpose of this study is to investigate the functional role of the human basal ganglia in the sensorimotor system. In particular, the investigators are interested in the possibility that the basal ganglia participate in "filtering out" sensory stimuli that are irrelevant to the current behavioral goal. Additionally, the investigators are interested in how this type of sensorimotor processing in these brain areas is related to the severity of movement disorders such as Parkinson's disease and essential tremor.

To do this, the investigators will study both healthy individuals and Parkinson's disease patients undergoing routine deep brain stimulation (DBS) surgery. During the surgery, investigators will place the DBS electrode as routinely performed and additionally place an extra, temporary "strip" electrode along the surface of the brain. Participants will then perform a short behavioral task testing sensorimotor function while investigators record the neural signals from these electrodes. The task will involve the delivery of sensory stimuli (visual, vibrotactile, electrical, and/or proprioceptive), to which the participant will be asked to perform a certain motor response. In order to fully measure the variables of interest, investigators will also attach small stickers (electrodes) to the skin of areas involved in movements for measuring muscle activity (such as the face and limbs), and may attach small, noninvasive devices around the wrist, finger, or arm (e.g., accelerometers) that measure position. The investigators may also apply EEG electrodes to the scalp to measure global brain activity or place a microphone in front of the subject to record speech.

In addition to recording this baseline brain activity, the investigators will evaluate whether deep brain stimulation and dopaminergic medication alters the recorded activity and task performance. Typical deep brain stimulation involves administering specific parameters of high-frequency electrical pulses to achieve clinical benefit. Routine operations involve testing these parameters in the OR in awake patients. For this study, investigators will administer either this high-frequency stimulation or various other patterns of stimulation (e.g., low-frequency, burst stimulation) and measure the changes in behavior and brain activity. As a method of validation, the investigators will also deliver paired pulses of stimulation that enable analysis of stimulation-evoked activity.

Finally, the investigators will correlate recorded brain activity with measures of participants' individual disease severity.

An Ericksonian hypnosis session given to patients during a scintigraphic or PET examination, in a conventional manner, i.e. the hypnotherapist (MERM) is close to the patient in the examination room at the time of the session and communicates with him/her without any special device dedicated to this purpose.

Ericksonian Hypnosis

A hypnosis session given to patients during a scintigraphic or PET examination, in a remote manner, i.e. the hypnotherapist (MERM) is in the control room at the time of the session and communicates with the patient via a microphone and the patient has headphones.

In Nuclear Medicine, the examinations are long (20-60 minutes) and the patients must remain immobile, sometimes fasting. The anxiety of the latter can lead to poor quality examinations and sometimes, although already injected with radioactive drugs, the patients refuse the examination. In imaging, the use of hypnosis (prior to the MRI examination or with the patient during a scintigraphic examination) is frequent due to the conformation of MRI or scintigraphic machines, particularly for claustrophobic patients (2-2.5% of cases).

Medical electroradiology manipulators (MERM) have been trained to practice Ericksonian hypnosis whose effectiveness in combating anxiety is no longer in question. Scientific studies by Faymonville et al, 2006 and Rainville et al, 2002, have shown the effectiveness of this method in managing anxiety using the simplified STAI-6 scale before and after hypnosis.

The dosimetric study of the MERM position would then be greatly modified in favor of a decrease in exposure targeted by the June 4, 2018 decree on personnel safety. The impact of whether or not the MERM is physically present near the patient would also be studied. If minimal, this will resolve the current contradiction between the quality of patient care delivered and the radiation protection imposed in nuclear medicine.

The investigators propose here a pilot study evaluating remote-delivered Ericksonian hypnosis versus conventionally-delivered Ericksonian hypnosis, which will allow for the sizing of a subsequent multicenter randomized non-inferiority controlled trial. Indeed, there is currently no data available on the non-inferiority margin of this technique.

Scientific studies by Faymonville and Rainville have shown the effectiveness of this method in managing anxiety using the simplified STAI-6 scale before and after hypnosis.

During nuclear medicine examinations, the proximity of MERMs to patients to practice conventional hypnosis results in significant exposure to radioactive radiation, which is not compatible with radiation protection guidelines. Some MERMs have been practicing hypnosis for several years, others are reluctant. However, exposure decreases as a function of the decrease in exposure time and the distance to the radioactive source. If the examination time cannot be modified, the distance to the patient could be by using an original method, remote hypnosis using a headset and microphone to provide Ericksonian hypnosis sessions in the same way as those provided in conventional sessions. The dosimetric study of the MERM position would then be greatly modified in favor of a decrease in exposure targeted by the June 4, 2018 decree on personnel safety. The impact of whether or not the MERM is physically present near the patient would also be studied.

Indeed, there is currently no data available on the non-inferiority margin of this technique. This pilot study will also allow for extensive documentation of the implementation of the remote hypnosis technique and for any necessary adjustments to the intervention to ensure its feasibility, acceptability, and reproducibility in the subsequent trial.

The hypothesis is that the use of remote-assisted hypnosis in nuclear medicine reduces patient anxiety as much as conventional Ericksonian hypnosis, while limiting the radiation exposure of the MERMs.
