Hyperkinetic movement (HKM) can encumber nonverbal communication of preference. Caregiver and clinician interpretation of preference are recognized as a valuable but limited proxy translation. It is known that biomechanical signals can differentiate among movement patterns in various populations. We hypothesize that preference is encoded in HKM; to test this hypothesis we propose a unified approach to detect preference within HKM, fusing observational and quantitative techniques while incorporating caregiver and clinician perspectives. We illustrate this method through two case studies; in the first case preference is detectable by both visual (fair agreement) and accelerometer classification (68.5% accuracy) whereas in the second case preference is only detectable by accelerometer-based classification with 62.9% accuracy. The proposed procedure may enable researchers to effectively explore communicative movement patterns in children with HKM. The findings warrant further investigation into potential communicative patterns in HKM.
