Introduction

The advancement of artificial intelligence (AI) has significantly transformed the field of prosthetic technology, enabling the development of highly adaptive and intelligent systems that enhance mobility and user experience [1]. Conventional prosthetic devices often rely on pre-programmed control mechanisms that lack flexibility and require frequent manual calibration [2]. These limitations hinder their ability to adapt to dynamic environments and individual user needs [3]. The integration of unsupervised learning and reinforcement learning into prosthetic control has emerged as a promising solution, offering the potential to create self-learning prosthetic systems capable of adjusting autonomously based on user behavior and environmental factors [4]. By leveraging AI-driven learning techniques, modern prosthetic devices can analyze sensor data, identify movement patterns, and refine their control strategies without extensive human intervention [5]. 

Unsupervised learning plays a crucial role in identifying latent features from complex biomechanical data, allowing prosthetic devices to detect movement patterns, muscle activation signals, and gait characteristics without requiring labeled training datasets [6]. Techniques such as clustering and dimensionality reduction enable the segmentation of movement data into meaningful categories, improving the accuracy and adaptability of control algorithms [7]. In contrast, reinforcement learning enhances prosthetic functionality by continuously optimizing movement execution through trial-and-error learning [8]. This adaptive framework enables prosthetic devices to adjust to the user’s biomechanics in real-time, improving performance efficiency while minimizing discomfort and cognitive load [9]. The combination of these learning paradigms has the potential to revolutionize personalized prosthetic adaptation, ensuring that devices evolve dynamically with user-specific physiological changes [10].
