The increasing incidence of neurological disorders among older adults, including neuromotor and neurosomatic conditions, underscores the critical need for early detection and continuous monitoring. These disorders significantly impact the aging population’s quality of life, making early diagnosis and management essential for maintaining independence and functionality in daily activities. Recent advancements in smart sensor technologies offer promising avenues for non-intrusive monitoring within living environments, enhancing the ability to detect subtle changes in health status over time. This paper explores the innovative application of a single RGB-D camera for gait analysis in the elderly, aiming to facilitate early detection and follow-up of neurological disorders, such as Parkinson’s and Huntington’s Diseases, fibromyalgia, and migraine. Gait, as an integral component of the activities of daily living, provides …
