Trial summary

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-a disorder affecting patients with… Read more about this study

  • Ages Any age
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Normal subjects.
  • Patients diagnosed with Ideomotor apraxia with a single left hemisphere lesion.
  • Patients with Ideomotor apraxia with corticobasal ganglionic degeneration.

Who cannot join

  • Normal subjects: abnormal neurologic examination or history of neurologic disorders.
  • Ideomotor apraxic patients: a second neurologic disorder including more than one brain lesion or the inability to cooperate fully.
  • Normal and Ideomotor apraxic patients: cognitively impaired subjects will not be accrued (for the purposes of this study, patients that can provide full informed consent for the study are not considered cognitively impaired).
  • For MRI studies, patients with metallic implants to remove potential risks from this procedure.
  • For MRI purposes, women who are pregnant are excluded from this part of the protocol. Therefore, all women of childbearing potential will have a pregnancy test performed, which must be negative, before proceeding.

About this study

Official title: EEG Analysis of Ideomotor Apraxia

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-a disorder affecting patients with stroke and other brain lesions. These patients have problems with timing, sequence and spatial organization of certain types of movements.

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 ideomotor apraxia with a single left brain lesion may be eligible for this study.

Study participants will be asked to make certain movements with their arms or hands, such as waving and using scissors. Brain and muscle activity will be measured during these tasks with EEG and EMG recordings. Patients may be asked to repeat these tests over time as their condition changes (such as during recovery from a stroke) to gain information about the recovery process.

Read the detailed description

Ideomotor apraxia is a disorder affecting patients with stroke and a variety of other brain lesions. The disorder involves problematic timing, sequence, and spatial organization of gestured movements. As a result, patients suffer from incorrect temporal and spatial components to movements as evidenced during pantomime of transitive and intransitive movements. The errors can be seen in left and right hemisphere damaged patients during intransitive movements, but lesions predominate in the left hemisphere for inability to pantomime transitive movements. Thus far, damage to parietofrontal circuits has been implicated in significantly contributing to this disorder. These circuits, which pave the way for sensorimotor processing, are of clear interest in the nature of praxis.

In the present study, we plan to evaluate further the parietofrontal circuits in these patients. Using EEG, we will analyze the movement related cortical potentials (MRCP) in these patients compared to controls to evaluate any cortical planning differences. We will analyze how the circuits play a role in transitive and intransitive movements in normal subjects and patients with Ideomotor apraxia. Each patient will make a series of movement during 64 channel EEG and EMG recordings. Following recordings, analysis will be made of the event related desynchronization (ERD) and the MRCP. Further analysis will look at the activation of the parietofrontal circuitry in patients using correlation and coherence methods. For the same purposes, MEG studies will be performed to assess similar measures.

Questions about this trial

What is this clinical trial studying?

An observational study of Ideomotor Apraxia, run by National Institute of Neurological Disorders and Stroke (NINDS) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00024999, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
