Abstract | Sarcopenia, an age-related syndrome characterized by muscle mass and function loss, significantly impacts the quality of life in older adults. A machine learning approach using micro inertial measurement units (μIMUs) for noninvasive sarcopenia-prone screening through a single sit-to-stand (1STS) test is developed. The study involves 53 older participants (65–84 years), each wearing two IMUs, i.e., one on the thigh and one on the waist. The 1STS motion is divided into four phases and extract 510 features from the collected data. Phase 1 is crucial for distinguishing healthy from sarcopenia-prone participants, while Phase 2 is significant in differentiating risk levels. Key indicators include anterior–posterior and mediolateral movements, particularly along the y-axis and z-axis of the sensors. Five classification algorithms (support vector machine (SVM), K-nearest neighbors (KNN), decision tree, linear discriminant analysis, and multilayer perceptron (MLP)) with selected features are trained. The method achieves 98.32% accuracy using SVM and MLP in distinguishing healthy from sarcopenia-prone participants and 90.44% accuracy using KNN in classifying participants across four risk levels (0–3) based on physical performance severity. These results suggest that the proposed method provides a low-cost, nonspecialist technique for large-scale sarcopenia-prone risk screening and assessment of physical performance severities. |
