NCT01581580
Background: \- Deep brain stimulation (DBS) is an approved surgery for certain movement disorders, like Parkinson's disease, that do not respond well to other treatments. DBS uses a battery-powered device called a neurostimulator (like a pacemaker) that is placed under the skin in the chest. It is used to stimulate the areas of the brain that affect movement. Stimulating these areas helps to block the nerve signals that cause abnormal movements. Researchers also want to record the brain function of people with movement disorders during the surgery. Objectives: * To study how DBS surgery affects Parkinson s disease, dystonia, and tremor. * To obtain information on brain and nerve cell function during DBS surgery. Eligibility: \- People at least 18 years of age who have movement disorders, like Parkinson's disease, essential tremor, and dystonia. Design: * Researchers will screen patients with physical and neurological exams to decide whether they can have the surgery. Patients will also have a medical history, blood tests, imaging studies, and other tests. Before the surgery, participants will practice movement and memory tests. * During surgery, the stimulator will be placed to provide the right amount of stimulation for the brain. Patients will perform the movement and memory tests that they practiced earlier. * After surgery, participants will recover in the hospital. They will have a followup visit within 4 weeks to turn on and adjust the stimulator. The stimulator has to be programmed and adjusted over weeks to months to find the best settings. * Participants will return for followup visits at 1, 2, and 3 months after surgery. Researchers will test their movement, memory, and general quality of life. Each visit will last about 2 hours.

Parkinson's disease (PD) is one of the most common neurodegenerative diseases. Patients frequently experience decreased amplitude and speed of movements, balance, and gait problems. Although the basal ganglia have been the target neuroanatomical region for movement disorders in Parkinson's disease for many years, recent neuroscience studies have shown that the cerebellum also plays an important role in the disease and is an important alternative target for treatment applications. While medical applications are becoming current for this purpose, there is a significant deficiency in the literature in terms of physiotherapy applications. Reaction and dual task are activities that have been shown to naturally stimulate the cerebellum. The aim of this study is to examine the effects of combined exercise training, which includes dual skills and reaction activities that have been shown to stimulate the cerebellum in PD, on the reaction time, intuitive postural adjustments, and balance of PD. Our study is an original study that targets the cerebellum in PD with reaction training according to current neuroscience results, aims to contribute to the field of neuroscience and translational medicine, and has no previous example in the literature. This study will include patients diagnosed with idiopathic Parkinson's disease by a specialist physician. The PD patients included in the study will be randomly divided into two groups. The reaction group will be applied a combined reaction training program consisting of 15 exercises, including a light reaction measurement and an exercise system. The conventional group will be applied an exercise program consisting of only 15 exercises without reaction training. The patients included in the study will be subjected to reaction time, amplitude of intuitive postural adjustments, balance, and functional mobility assessments before and after the training. The light reaction measurement and exercise system will be applied for the measurement of reaction time of the volunteers, the static-dynamic balance assessment device for the assessment of intuitive postural adjustments and the static-dynamic balance assessment device for balance assessments, and the Timed Up and Go Test will be applied to assess functional mobility. At the end of the study, we aim to demonstrate the effect of combined exercise training targeting the cerebellum compared to conventional exercise training in Parkinson's patients, to create clinical outcomes for the inclusion of the cerebellum in more physiotherapy programs in Parkinson's disease, and to provide clinical outcomes for physiotherapists for a new exercise protocol, as well as making scientific contributions to the fields of translational medicine and neuroscience.
