Background: Active orthosis is one of the main research topics in rehabilitation field and recovery of an injured limb. Within the injuries we can highlight the injury of brachial plexus generates the total loss of motor capacity of the upper limb.
Materials and methods: This research identifies the level of disability of this lesion and seeks to improve the motor capacity of people with lesions in the plexus by using an active orthosis.
Results: We built a printed by a 3D printer with ABS material, and using a MyoWare EMG muscle sensor activated with shoulder muscles to control two servomotors located at elbow and wrist joints.
Discussion: This work was able to improve the motor skills of two patients suffering from this injury, achieving elbow flexion, wrist extension and wrist flexion with the help of the built-in orthosis, as well as identifying some difficulties that must be considered in order to have a fully functional product.
Evidence Level: IV.
