This study will explore the decision-making experiences of women who are currently pregnant following a period of infertility on whether or not to undergo an invasive prenatal test (IPT) procedure, such as amniocentesis or chorionic villus sampling. Women who become pregnant after infertility often experience heightened anxiety regarding the outcome of the pregnancy. When choosing whether or not to have IPT they are faced with a complex decision, set in the unique context of a pregnancy that they often perceive as exceptionally precarious. Women who are pregnant with their first child after a period of infertility and have made a decision regarding whether or not to undergo IPT may be eligible for this study. Participants complete an online password-protected questionnaire that measures infertility and decision-making variables and explores women's perceptions of the impact of infertility on their IPT decision-making process. The questionnaire covers the following areas: * Subject's demographic information, such as age, marital status, number of children, education, race, ethnicity * Subject's infertility history * Subject's thoughts and feelings about infertility * Subject's thoughts and concerns about other people's (e.g., husband, doctor, other infertile women) opinions about IPT * Subject's decision about whether or not to have IPT and her feelings regarding the decision * The effect of subject's infertility history on her decision to have or not have IPT
NCT00025701
This study will examine how the brain operates during execution and control of voluntary movement and what goes wrong with these processes in disease. It will use electroencephalography (EEG) and electromyography (EMG) to compare brain function in normal subjects and in patients with focal hand dystonia. In dystonia, involuntary muscle movements, or spasms, cause uncontrolled twisting and repetitive movement or abnormal postures. Focal dystonia involves just one region of the body, such as the hand, neck or face. EEG measures the electrical activity of the brain. The activity is recorded using wire electrodes attached to the scalp or mounted on a Lycra cap placed on the head. EMG measures electrical activity from muscles. It uses wire electrodes placed on the skin over the muscles. Adult healthy normal volunteers and patients with focal hand dystonia may be eligible for this study. Patients will be selected from NINDS's dystonia patient database. Participants will sit in a semi-reclining chair in a darkened room and be asked to move either their right index finger, right foot, or the angle of their mouth on the right side at a rate of one movement every 10 seconds. Brain and muscle activity will be measured during this task with EEG and EMG recordings.
