The (dys)functioning motor system provides a challenging system to study. For a thorough understanding of the human motor system simultaneous measurements of as many involved subsystems as possible would be a great advantage.
Use EMG to relate superfluous movements to brain activity. Calculate residual EMG by extracting the deviation from mean task-related EMG and add this as regressor to the GLM.
Simultaneous EMG-fMRI recordings and integrated EMG-fMRI analyses have additional value over fMRI alone. These methods will facilitate future studies of movement disorders. In particular, in combination with other MR-compatible physiological recordings, applications are to be expected in studies of patients with spontaneous pathological movements, such as tremor, myoclonus, dystonia, chorea and Parkinson’s disease.
