Development on the project
in further research, there are multiple researches that shown nerve damage associating with injury. One of the research here shows that 45% out of 101 patients with primary shoulder dislocations and humeral neck fractures show signs of nerve lesions and is shown on their EMG. An article found online describing the EMG test in simple terms here explains that the test involves 2 parameters of electrical current conduction in a nerve. The test involve testing the delay and the amplitude of the nerve group. A delay may indicate a damaged or pinched nerve and loss in amplitude may indicate that certain fibres in a nerve bundle is not conducting at all.
A simple project found in youtube demonstrates a simple emg circuit to show the delay and amplitude of a nerve. This project amplifies the possibility of developing a simple device to diagnose an injury.
