Study of How Spinal Cord Injury Changes Body Awareness and Brain Activity Using Behavioral Tests and MRI

What this Trial Is About

Spinal cord injury SCI occurs when trauma or other factors damage the spinal cord, disrupting communication between the body and brain. This can lead to changes in body awareness called disembodiment, where sensations feel different or limbs seem out of place. The study aims to explore how SCI affects embodiment, its impact on daily life, and the related brain activity using functional magnetic resonance imaging fMRI. Both individuals with SCI and healthy participants will take part in this research. Participants will be divided into groups some with SCI will undergo a detailed behavioral assessment of embodiment and sensory-motor symptoms, while others will also have brain activity measured through fMRI during a task involving a modified rubber hand illusion. Healthy controls will perform similar behavioral assessments, with some also undergoing fMRI. The fMRI task includes watching virtual legs being touched while their own legs are stroked to assess the feeling of embodiment. Each participant will attend one examination lasting about 2 to 2.5 hours, including approximately 55 minutes inside the MRI scanner. Researchers will evaluate responses to questionnaires measuring body feelings, pain, emotions, cognition, and daily functioning. Brain activity and embodiment strength will also be assessed. The study will monitor various physical, psychological, and quality of life aspects to understand how SCI changes body awareness.
