ClinConnect Summary

This clinical trial, titled "CNS Changes Following Amputation," aims to explore how the brain changes after someone is born without an upper limb, a condition known as upper limb amelia. Researchers want to understand how the brain processes sensory information and how these changes might affect everyday behaviors, like adapting to the absence of a hand or experiencing pain. By comparing individuals with upper limb amelia to healthy individuals, the study will use advanced imaging techniques and behavioral tests to learn more about how the brain reorganizes itself and whether early life experiences play a significant role in this process.

To participate in the study, you must be between 18 and 75 years old and have a complete absence of a hand due to congenital amputation. Participants will need to sign a consent form and will be assessed using magnetic resonance imaging (MRI) and various tests. It’s important to note that individuals who have certain medical conditions or difficulties with MRI, such as claustrophobia, cannot participate. The study is currently recruiting and aims to provide valuable insights into the brain’s adaptability and how it relates to practical outcomes for those living with upper limb amelia.
