The loss of upper limb functionality is a debilitating condition affecting many individuals. While the development of external devices has achieved remarkable capabilities in replicat- ing upper limb functions, there remains a critical need for effective control strategies. The objective of this experimental Master’s Thesis is to develop and validate a software appli- cation for the real-time translation of the electrical activity of forearm muscles into hand movements. Additionally, the solution provides a tool for visualizing kinematics output. The software application was developed in Simulink as an extension of the MEACS system, the EMG amplifier developed by LISiN - Politecnico di Torino.
