Design and Implementation of a Customized Myoelectric Prosthesis for a Transradial Amputation Level with Interactive Theming to Measure the User’s Psychological Well-Being

This article describes a customized myoelectric prosthesis for a transradial amputation level with an interactive theme to measure psychological well-being in an 8-year-old child aged 8 and 4 months. The clinical assessment is fundamental to determine the type of prosthesis that best suits the patient’s needs. At the same time, factors such as age, profession, and daily activities, among others, significantly influence the design of the customized prosthesis. The methodology used in this study includes scanning the patient’s dummy, designing or modeling the prosthesis using $$360^\circ $$ fusion software, 3D printing of the prosthesis model, post-processing, assembly, and application. The results obtained show that the customized prosthesis designed with a theme and successfully fabricated allowed the child patient to recover the mobility and functionality of his upper limb. The prosthesis was controlled by myoelectric signals detected with the MyoWare sensor, which allowed the user to emit signals to execute the opening and closing action of the hand. This study highlights the potential of electronic engineering and 3D printing to improve the quality of life of a child with a missing upper limb.
