Design of exoskeleton framework for hand motion aids in Brachial plexus injury cases

Brachial plexus injury is one of the conditions that will limit function of mobility in the upper extremities, including lack of pain and diminished muscle mass, which can occur as a result of a malfunction of the nerves that regulate body motions. Numerous forms of treatment, such as rehabilitation and function training, are still conventional and require a lengthy period depending on the extent of the injury. The exoskeleton can be an alternative for paralyzed people, especially those who have suffered brachial plexus injuries, to increase the function of the weaker hand so they can perform certain daily duties (ADL). In order to support and position the paralyzed hand, this research was done to develop an exoskeleton that takes biomechanical considerations into account and has a hand support that is 20 degrees above the palm. A simple control system and 3D printing technology are also used to make the exoskeleton portable. The subject's hands are changed to create the exoskeleton design, which is an efficient way to make an exoskeleton with the capabilities needed to do ADL. This exoskeleton design has been shown to help patients, as shown by the capacity to hold various items with flexion and extension movement mechanisms that are frequently encountered in daily life. The dimensions of objects that a subject can reach while wearing an exoskeleton are determined by performing a hand function test, and this exoskeleton design has been shown to help patients.
