Design of Neuromuscular Stimulation to Supervise Parallelized Arm using Human-Machine-Human Interaction

摘要

Paralyzed person or the person with physical disorders wont be able to move their body parts viz. hand or arm because of abnormal behavior of spinal cord or its injuries. This movement inabilities may result to mental, moral or physical disorder resulting into sometimes cardiovascular diseases, bone demineralization. In such cases, the surgical solution is to use neuroprosthetic arm replacing paralyzed arm. This is expensive and also impact normal human behavior and demoralize him or her. The proposed neuroprosthetics approach avoids the need of replacing the arm and also avoids critical surgery which increase the moral and confidence of patient. The approach involves designing a model that interfaces with living neurons to control a device or for sensory substitution. In proposed approach, human to human interaction using model is required to setup. The design is developed to supervise the parallelised arm under the control of normal human arm. For this, it creates an interface which works in directions given by normal human arm with patients's arm. This interface is designed using microprocessor to compute and process signals and transfer to electrode attached to electrical muscle to stimulate the damaged arm. The electrical signals are generated in controlled manner with effective and enough strength level equivalent to the brain signals required for motor nerves in collaboration with sensor nerves. This helps patient with paralyzed arm to perform directed operations under the governed movement of normal human being. This avoids the use of traditional prosthetic arm surgery and can use proposed nervous bypass system without any surgery.
