Krause F, et al. - Via a single session study on 25 healthy volunteers aged between 18 and 25 years, the contributors intended to explore the possibilities of providing subjects with the information of active head motion (a very common and considerable problem in clinical as well as empirical magnetic resonance imaging applications) using tactile feedback, reducing the head motion and consequently improving the image quality. Significant reduction in both translational as well as rotational head motion post application of medical tape to the forehead of subjects to provide tactile feedback was noted. A negative quadratic relationship between head motion with and without feedback was noticed. Hence, the researchers concluded that these tested method provided a simple and cost-efficient way for the reduction of the subjects' head motion, and could be especially beneficial when extensive head motion is expected a priori.
