NCT04409600
Chronic Exertional Compartment Syndrome (CECS) in the lower leg is a debilitating condition in highly active individuals. Pain occurs in 1 or several leg compartments upon an exertional activity, typically running, that quickly dissipates once the activity stopped. Surgical fasciotomy is the standard for treating lower leg CECS, but success is variable. Complications may occur post-surgery and there is a potential for a repeat procedure. Recovery times post-surgery also vary greatly. Conservative treatments, such as gait retraining and botulinum toxin injections, are emerging as non-surgical options for the treatment of CECS with success through published case reports and case series. This study aims to evaluate the use of these non-surgical treatment options for CECS in the anterior and lateral leg compartments with a follow up for at least 2 years across multiple study sites.
NCT01087281
Background: \- Previous studies have shown that people with certain types of brain damage may have particular problems paying attention and processing things that they see. Researchers are interested in comparing how people with brain damage and without brain damage process visual images. Objectives: \- To better understand the areas of the brain involved in paying attention to things that are seen. Eligibility: \- Individuals at least 18 years of age who either have had damage to one or both sides of specific parts of the brain (e.g., stroke, injury, certain neurosurgery procedures) or are healthy volunteers. Design: * The study involves 4 to 10 visits to the NIH Clinical Center over 1 to 2 years. Each visit will last approximately 2 hours. * Participants will be screened with a medical history and physical examination, and may have the cognitive testing described below during the same visit. * On the first visit and for at least one visit thereafter, participants will have cognitive testing to evaluate thinking and memory. These tests will be either written tests or computer-based tests. * Some participants will qualify for functional magnetic resonance imaging (fMRI) as part of the study. This part will involve a decision-making task that will be performed on a computer during the fMRI scan. Additional scans may be required as directed by the study doctors. * Some randomly selected participants will be asked to have magnetoencephalography (MEG), a procedure to record very small magnetic field changes produced by brain activity. * During the behavioral training, or fMRI or MEG scanning, participants may be monitored with equipment to track eye movements.
