Abstract:
The proposed work treat about the analysis and development of an orthotic device for people suffering Radian Nerve Palsy known as wrist drop. This disability impairs the correct functionality of the human wrist, shirking the fingers. For the development of the device the main anthropometric measurements has been done as well as the wrist anatomy has been studied in order to develop a more adaptive and identic device. The device design is based on the ergonomic design of the products, and user requirements. One DC actuator realizes the extension of the wrist, through a simple mobile application. Silicone and ABS materials were used for the development of the orthotic device. The experimental results of the extension function show that the device is able to extend the human wrist in a natural way.
