This study delves into decoding hand gestures using surface electromyography (EMG) signals collected via a precision Myo-armband sensor, leveraging machine learning algorithms. The research entails rigorous data preprocessing to extract features and labels from raw EMG data. Following partitioning into training and testing sets, four traditional machine learning models are scrutinized for their efficacy in classifying finger movements across seven distinct gestures. The analysis includes meticulous parameter optimization and five-fold cross-validation to evaluate model performance. Among the models assessed, the Random Forest emerges as the top performer, consistently delivering superior precision, recall, and F1-score values across gesture classes, with ROC-AUC scores surpassing 99%. These findings underscore the Random Forest model as the optimal classifier for our EMG dataset, promising significant advancements in healthcare rehabilitation engineering and enhancing human–computer interaction technologies.

This study explores the development and pilot testing of an exergame designed for the rehabilitation of individuals with upper limb deficits. While traditional physiotherapy is effective, it often fails to fully engage patients due to its repetitive nature. This research integrates a novel exergame into physiotherapy regimens, aiming to enhance patient motivation through a gaming experience that complements conventional sessions. The exergame is structured around a narrative-driven adventure, with exercises embedded in gameplay that mirror adjustable physiotherapy routines. It utilizes the Myo armband, a wearable electromyography device, to capture muscle activity and movement. The system, part of a web-based platform, is easily deployable in various settings, including home environments. Comprehensive evaluations with health professionals and neurological patients indicate that the exergame significantly improves patient engagement. This study not only demonstrates the potential of exergames in enhancing traditional therapy but also underscores the importance of patient-centered therapeutic tools. [ABSTRACT FROM AUTHOR]
