IoT System for Elbow Angle Assessment Applied to Orthosis Device

Joints, mobile structures of the musculoskeletal system, contribute to the autonomy and mobility of human beings, however they are requested by several events that may compromise their integrity impacting physiological activities. In these cases, medical assistance may be necessary and can be accompanied by the use of dynamic orthoses, which can promote immobilization and dynamic control of the structure. IoT fundamental can be applied to these devices and benefits the rehabilitation as it allows continuous and remote monitoring, but these type of devices are scarce in the market. The presented work developed a prototype of an orthosis with continuous monitoring elbow angle assessment during flexion and extension. The work encompassed structural, electroelectronic and software development. From the methodology proposed, it was possible to obtain good results since the data was properly acquired and displayed as well as the orthosis structure met the requirements in agreement to the validation method using the widespread software Kinovea. In this way, it was possible to develop an orthosis prototype for the elbow joint angle assessment using IoT fundamentals as a proof of concept.
