Brain Functional Connectivity Changes Following Cognitive Rehabilitation in Multiple Sclerosis: an fMRI Study

This study has been completed.
Information provided by (Responsible Party):
Mohammad Ali Sahraian, Sina Hospital, Iran Identifier:
First received: June 20, 2012
Last updated: September 11, 2014
Last verified: September 2014
This trial seeks to investigate brain network changes following cognitive rehabilitation in MS patients. The investigators hypothesize that rehabilitation interventions improve connectivity in the brain.Novel Magnetic Resonance Imaging technique is performed to investigate changes in brain plasticity.

Condition Intervention
MS (Multiple Sclerosis) Behavioral: Cog Rehab

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Single (Outcomes Assessor)
