Synergy-Based Evaluation of Hand Motor Function in Object Handling Using Virtual and Mixed Realities.

ABSTRACT: This study introduces a novel system for evaluating hand motor function through synergy-based analysis during object manipulation in virtual and mixed-reality environments. Conventional assessments of hand function are often subjective, relying on visual observation by therapists or patient-reported outcomes. To address these limitations, we developed a system that utilizes the leap motion controller (LMC) to capture finger motion data without the constraints of glove-type devices. Spatial synergies were extracted using principal component analysis (PCA) and Varimax rotation, providing insights into finger motor coordination with the sparse decomposition. Additionally, we incorporated the HoloLens 2 to create a mixed-reality object manipulation task that enhances spatial awareness for the
