We are currently using functional magnetic resonance imaging (fMRI) to investigate the cortical activation areas that control elbow and shoulder contraction. Using a nonferrous six-degrees-of-freedom load cell, we collect joint torque information at the shoulder and elbow simultaneously with fMRI data. We hypothesize, based on EEG results, that there is a greater overlap in the shoulder and elbow representations in the motor cortices in chronic stroke patients than in non-impaired participants.
