Active clinical trials for "Dyskinesias"

Decreased pulmonary function, peripheral muscle strength, and exercise capacity were reported in primary ciliary dyskinesia (PCD) in recent studies. We aimed to investigate the data conducted between 10 July 2015 and 10 January 2015 of pulmonary function, respiratory muscle strength, exercise capacity, physical fitness, and activities of daily living (ADL) in PCD and healthy counterparts retrospectively at the first stage of the study and the effects of inspiratory muscle training on pulmonary function, respiratory muscle strength, and exercise capacity in PCD patients with decreased inspiratory muscle strength from the database recorded between 10 July 2015 and 10 January 2015 retrospectively at the second stage of the study.

This study will examine genetic material obtained from blood and tissue samples of patients with congenital heart disease (CHD) and heterotaxy (an abnormality in the left-right positioning of organs in the body, also called situs inversus) to gain a better understanding of these disorders and of a lung disease called primary ciliary dyskinesia (PCD). CHD is prevalent in patients with heterotaxy. It is believed that certain forms of CHD or heterotaxy may have the same genetic origin as PCD. Individuals 2 years of age or older who have a CHD or heterotaxy or both may be eligible for this study. Participants undergo some or all of the following tests and procedures: Blood tests, electrocardiogram (EGC) and chest x-ray. Saliva collection: Subjects rinse their mouth with water, and then spit approximately 1.5 cc of saliva into a sterile container. Buccal swabs: A small soft, toothbrush-like swab is rubbed on the inside lining of the cheek to collect tissue samples. Nasal tests to measure nasal nitric oxide levels and to obtain tissue samples from the inside of the nostrils: For the nitric oxide level test, a rubber probe is inserted into one of the nostrils until it fits snugly and comfortably. The subject then takes a deep breath and then exhales all the way out through the mouth through a plastic device. During exhalation, gas measurements are recorded on a computer. To obtain tissue samples, a device is inserted in a nostril and scraped gently against the inside of the nose. Echocardiography: This ultrasound test of the heart uses sound waves to obtain pictures of the heart. A small wand with a warm clear gel is moved around the chest to obtain the images. Abdominal ultrasound: This ultrasound test of the heart uses sound waves to obtain pictures of the abdominal organs. A small wand with a warm clear gel is moved around the abdomen to obtain the images....

Healthy volunteers and patients with diseases that involve problems clearing mucus from the lungs will be examined and tested to better understand the reasons for recurring lung infections in these patients and to try to develop better ways to diagnose and treat them. The study will also try to identify the genes responsible for these diseases. Healthy volunteers 18 years of age and older and patients 2 years of age or older with suspected primary ciliary dyskinesia (PCD), variant cystic fibrosis (CF) or pseudohypoaldosteronism (PHA) may be eligible for this study. Patients enrolled in the Natural History Study of Nontuberculous Mycobacteria at NIH or other NIH natural history protocols may also be enrolled. Participants undergo the following tests and procedures during a 1-day visit at the NIH Clinical Center, as follows: All patients and normal volunteers have the following procedures: Physical examination and review of medical and genetic history and family genetic history. Lung function test and measurement of oxygen saturation level. Nitric oxide measurement to measure the amount of nitric oxide production in the nose: A small tube is placed in the nose while the subject breathes through the mouth into a cardboard tube. All patients have the following additional procedures: Blood tests for liver and kidney function, blood count, immunoglobulins and pregnancy test (where appropriate). Blood test or buccal scrape (brushing the inside of the cheek) to obtain DNA to look for gene mutations that cause PCD, CF or PHA. Scrape biopsy of cell lining the inside of the nose: A small toothpick-sized plastic stick with a tiny cup on the end is used to get nasal lining cells to look at the cilia (hair-like structures that move mucus). Semen analysis (in some men) to test sperm tail function or structure. Patients suspected of having a variant of CF or PHA, including nontuberculous mycobacterial lung disease, have the following additional procedures: Sweat chloride test: A medicine is placed on the arm to produce sweat; then, a very low level of electric current is applied for 5 to 12 minutes. Sweat is collected in a plastic tube and tested for salt content. Blood draw for CF genetic testing, if necessary, and to measure levels of the enzyme trypsin. Saliva collection to measure sodium and chloride content. Nasal potential difference to measure the electrical activity of the cells lining the inside of the nose: A soft plastic tube filled with a salt solution is passed into the nasal passage and a sterile needle is placed under the skin of the arm. This test provides information about how the lining of the nose is able to get used to changes in temperature and humidity. (Normal volunteers also have this test.)

Approximately twenty four (24) subjects will participate in this research trial. The research trial will be conducted in approximately twelve (12) medical centers in the following countries: Germany, France, South Africa, Austria and Canada. The research trial will last until December 2011.

Primary ciliary dyskinesia (PCD), also known as Kartagener syndrome, is a genetic disorder of the cilia, which are microscopic hair-like cells. Cilia work to keep the respiratory system clean by moving mucus that contains debris to the large airways, where it can be coughed out. People with PCD have cilia that do not move properly and therefore are not effective in cleaning the respiratory system. This study will determine when PCD starts and how it changes over time, specifically in terms of how well the lungs work, what germs grow in lung secretions, and how the lungs look on computed tomography (CT) scans.

The ultimate goal of this proposal is to reduce dyskinesia in Parkinson's Disease (PD) patients. Dyskinesias are abnormal movements, often caused by the standard treatment for PD symptoms, levodopa. In this study, we will test if biochemical devices are equal to the clinical rating system in measuring dyskinesias.

The main objective of this research is to see the effect of two mental practice techniques on static and dynamic balance.

The purpose of this study was to analyze if a low ankle dorsiflexion range is associate with dynamic knee valgus in youth basketball players.

Primary ciliary dyskinesia is an autosomal recessive disorder characterized by abnormal ciliary movement and disrupted mucociliary clearance. In uncleaned airways, microorganisms and respiratory irritants cause inflammation and infection. Permanent rhinitis and chronic sputum cough are typical features in primary ciliary dyskinesia patients. Primary ciliary dyskinesia is a disease that threatens lung function from pre-school age. One of the main causes of respiratory muscle weakness in chronic lung diseases diseases is worsening of lung function. Such a weakness causes alveolar hypoventilation, microatelectasis, reduction of the cough strength .The cough strength is important for airway cleaning. Exercise capacity is affected in chronic lung diseases. Assessment of exercise capacity in chronic lung diseases is prognostically important. Reduced exercise capacity and pulmonary function in PCD cause decrease in physical activity level. PCD patients have low quality of life and early recognition has been found to affect the quality of life positively. Children with chronic illness have higher level of depression than healthy children. In literature, no study investigated respiratory muscle strength, exercise capacity and physical activity PCD patients. Therefore, the investigators aimed to compare aforementioned outcomes in PCD patients and healthy controls.
