Assessment of Fine Motor Skills Using Digital Serious Games: A Comparative Study with the Conventional Box and Block Test

The assessment and rehabilitation of fine motor skills are essential in clinical practice, particularly for individuals with neurological or musculoskeletal impairments. The Box and Block Test (BBT) is a widely used standard tool; however, it lacks digital capabilities for automated measurement and remote monitoring. This study presents two digital serious games designed to assess and support fine motor skills. The first game is a direct digital adaptation of the BBT, while the second mimics its core movements while introducing enhanced interaction features and flexibility. A total of 50 participants performed the conventional BBT and both digital games. The present evaluation represents a preliminary validation in healthy adults and provides a foundation for future clinical studies involving individuals with motor impairments. Performance metrics were collected and analyzed to compare outcomes and examine correlations between real-world and digital assessments. The results indicate significant correlations between BBT scores and performance in both digital serious games, supporting their validity as assessment tools. Additionally, the second game provided richer interaction data, suggesting potential for more comprehensive evaluation. These findings highlight the potential of serious games as reliable and engaging tools for fine motor assessment and rehabilitation in both clinical and remote settings.
