Active clinical trials for "Parkinson Disease"

The purpose of this study is to evaluate the benefits of a biomechanical wedge system - The APOS system, for improving the stability of gait, mobility and quality of life in Parkinson's disease patients.

This study will identify symptoms and other characteristics of Parkinson s disease that may be associated with changes in a gene called leucine-rich repeat kinase 2 (LRRK2). Changes in this gene have been found in patients with and without a family history of Parkinson s disease. This study will examine people with Parkinson s disease to try to identify how symptoms develop over time. First-degree relatives of patients will also be studied. People 18 years of age or older with Parkinson s disease or people who have a first-degree relative with Parkinson s disease may be eligible for this study. Participants visit the NIH Clinical Center every other year for 10 years for some or all of the procedures listed below. Each visit requires 3-4 days of testing, which may be done on an inpatient or outpatient basis. Telephone interviews are conducted during the alternate years. History and physical examination. Smell testing: Subjects are asked to identify 40 different scents. Sensory testing: Objects with grooves and ridges are touched to subjects fingertips. With their eyes closed, the subjects are asked to say which way the grooves and ridges run on the objects. Neuropsychological evaluation: Subjects are asked about their memory and thinking and may be asked to complete some pen and paper tests. Psychiatric evaluation: Subjects are asked about psychiatric symptoms, including anxiety and depression. Blood drawing: Blood is drawn through a needle in the arm. Magnetic imaging resonance (MRI) scans of the brain: MRI uses a strong magnetic field and radio waves to obtain images of body organs and tissues. During the test, subjects lie on a table that can slide in and out of the MRI scanner (a metal cylinder surrounded by a strong magnetic field). The procedure lasts about 30 minutes, during which the subjects may be asked to lie still for up to 5 minutes at a time. Transcranial sonography (TCS): TCS uses sound waves to obtain images of the brain. Subjects lie on their back and an ultrasound device is moved around the scalp. Sleep study (1-2 night hospital admission): Subjects brain waves are recorded during sleep using electroencephalography (EEG). Their breathing rate, pulse and oxygen level are also monitored. Questionnaire: Subjects complete several questionnaires designed to obtain information on symptoms or traits that have been reported to be associated with Parkinson s disease.

The purpose of this pilot program is to develop and evaluate a new treatment program for depression in Parkinson's disease (PD). The treatment uses Cognitive Behavior Therapy(CBT)to teach patients how to become more aware of their thoughts and feelings and to change thinking patterns and behaviors that may be related to depressive symptoms. This is the first time that this treatment has been used in a group setting for depression in PD. Target population is patients in the Movement Disorders Clinic at Oregon Health & Science University who have Parkinson's disease and mild to moderate depression.

This study was designed to evaluate the symptomatic effects or potential disease progression slowing down effect of a kind of Traditional Chinese Medicinal Mixture in Parkinson's disease (PD) patients. The treatment phase includes 12 months period of Traditional Chinese Medicinal Mixture per day or placebo and 1 month wash-out period without herbal medicine and placebo.

The purpose of this study is (1) to determine if patient triggered sensory(auditory, visual and tactile) cues can help treat freezing of gait in Parkinson's disease, and (2) to assess if unexpected (randomized) cues are more effective than anticipated ones.

Levodopa-induced dyskinesias have been associated with irregular oscillatory discharge characteristics of basal ganglia. From the other hand, LEV which shares a different electrophysiologic profile than other antiepileptics, inhibits hyper-synchronization of abnormal neuronal firing in experimental models of epilepsy. LEV also reduces levodopa-induced dyskinesias in MPTP-lesioned macaques and modulates "priming phenomenon" which associated with long-term changes in synaptic function that can lead to dyskinesias in PD. Study objectives : To evaluate the effects of levetiracetam (LEV) in two doses (500 and 1000mg) vs placebo on disabling dyskinesias that develop as result of long-term treatment with levodopa, occurring at the time of maximal clinical improvement in patients with Parkinson's disease (PD). To evaluate the safety of LEV in patients with PD and antiparkinsonian medication.

A decrease or loss of the sense of smell is very common in patients with Parkinson's Disease even in the earliest stages of the disease. There have been no treatments that have been proven to improve sense of smell in patients with Parkinson's Disease. Rasagiline (brand name: Azilect) was approved by the U.S. Food and Drug Administration (FDA) on May 16th 2006 to be used by Parkinson's patients to treat the motor symptoms associated with the disease. The purpose of this study is to see if there is change in sense of smell after starting Rasagiline.

Falling is a complex and most disabling feature for patients with Parkinson's disease (PD). Previous studies suggested that falls in patients with PD are related to postural instability characterized by deficits in anticipatory postural adjustment (APA) for postural orientation in walking and standing and inadequate postural response to perturbation. The present study developed an innovative balance treatment with focus of anticipatory and compensatory postural control and examined its effects on enhancing balance and gait performance and decreasing fall rate in people with PD.

The recovery of walking ability is crucial to promote independence in daily living and is one of the major goal of neuromotor rehabilitation. Currently, standard rehabilitative programs are usually based on straight-walking training (SWT) and the assessment of their effects is performed through functional scales based on straight-walking trajectories, e.g. Timed Up and Go (TUG), 10 meters walking test (10mWT). Curved-walking training (CWT) may be interesting to provide an ecological and challenging context during rehabilitation. Indeed, CWT is based on demanding neural processes that drive an asymmetrical contribution at lower limb level, challenging balance ability and complex adaptation such as body weight shifting in response to centrifugal force and production of different step lengths. Up to now, literature has investigated CWT in healthy adults in terms of muscular activation, kinematics and kinetics of the movement. Results showed that CWT needs a different biomechanical strategy with respect to SWT. Nevertheless CWT has not been investigated in pathological adults. The present study aims at assessing the effectiveness of a rehabilitative physical therapy based on CWT with respect to traditional SWT for the recovery of locomotor abilities in neurological and orthopaedic patients. The hypothesis is that a training based on curved-walking is ecologically meaningful and may be superior with respect to standard training in improving balance, walking abilities, and independence in activity of daily live of patients. A secondary aim of the project is to propose an innovative functional scale based on the timed up and go on curved trajectory (CTUG), and to determine its reliability and responsiveness, establishing the minimum Detectable Change (MDC) and the Minimal Clinically Important Difference (MCID). A single-blind randomized controlled study is being carried out on three different populations: Post-acute stroke patients Idiopathic Parkinson Disease Femoral fracture A healthy group is also being recruited to provide reference values of CTUG. For each of the three populations, subjects are randomized into two groups. The experimental one performs a novel rehabilitative program composed by a 30-minute training on curved trajectory ("S" trajectory composed by two semicircle with a radius of 1.2 m) in addition to usual care. The control group performs an equal dose of traditional treatment on straight trajectories. Both groups undergo 20 90-minutes sessions of training (three times a week for seven weeks). Participants are evaluated at baseline (T0), after training (T1), and at a three-months follow-up visit (T2). The primary outcome measure is the 10mWT (minimal clinically important difference of 0.16 m/s identified by Tilson and colleagues). On the basis of this measure, a sample size of 70 subjects for each population was computed.
