We present a custom-built MR-compatible data glove to capture hand motion during concurrent fMRI experiments at 7 Tesla, and demonstrate that the hand motion measurements can be used to construct subject-specific BOLD signal models for fMRI analysis. Thermal and phantom tests showed our data glove can be used safely without degradation of image quality. Subject-specific signal models were constructed based on recorded kinematic measurements, revealing the relative contribution flexing, extending, and sustained isotonic extension. The ability to evaluate subject performance in real-time and create subject-specific BOLD signal models enables a wide range of experimental paradigms with improved data quality.
