Sensory Filtering in Parkinson's Disease

This study is looking at how the brain processes sensory information in people with Parkinson's disease. Researchers want to understand if a part of the brain called the basal ganglia helps "filter out" unimportant sensory signals and how this relates to movement problems. You may be able to join if you are an adult (18-89 years old) with advanced Parkinson's disease who is planning to have Deep Brain Stimulation (DBS) surgery. During the study, you would perform tasks involving sensory stimuli (like sights or touches) while brain activity is recorded during and after your DBS surgery. The study aims to see how your body responds to these stimuli, both during the surgery and one month later. This is an observational study, meaning researchers are watching and recording, not testing a new treatment. The study plans to enroll 30 participants, but its current recruitment status is unclear.

Study design
This is an observational study that plans to enroll 30 participants. It is not testing a new treatment but rather observing brain activity.
What's involved
You would perform behavioral tasks involving sensory stimuli during your DBS surgery and again one month after surgery. This involves responding to stimuli while brain activity is recorded.
Compensation
Not stated in the trial record.
Follow-up
Your body's response to stimuli will be measured one month after your DBS surgery.

  • Kinematic response to stimulus (intraoperative)Intraoperative

    Arm movements (hand position, velocity) recorded following stimulus onset, measured by joystick outputs.

  • Kinematic response to stimulus (postoperative)1 month post-op

    Arm movements (hand position, velocity) recorded following stimulus onset, measured by joystick outputs.

  • Latency of response to stimulus (intraoperative)Intraoperative

    Time from stimulus onset to start of motor response, measured by electromyography (EMG)

  • Latency of response to stimulus (postoperative)1 month post-op

    Time from stimulus onset to start of motor response, measured by electromyography (EMG)

  • Neural response to stimulusIntraoperative

    Brain activity recorded following stimulus onset, measured by local field potentials recorded from the electrocorticography (ECoG) and DBS electrodes.
