The purpose of this study is to assess the electromyography (EMG) signals of biceps muscle of paralyzed patients to know the condition of their affected muscle. For measuring the muscle signal, 5 voltages analog signal is sent to biceps muscle via EMG sensor with Arduino. As higher the voltage is, the condition of the muscle status is better. In this study, we have observed paralyzed patients in Dhaka city having different kinds of paralysis patients like Complete paralysis, Partial or incomplete paralysis and localized paralysis. The study also focused on monitoring different stage of paralysis like Flaccidity, dealing with appearance of spasticity, increased spasticity or decreased spasticity, complex movement combination, spasticity disappear and normal function return. This observational study was carried out in three largest and tertiary care hospitals located in Dhaka metropolitan area with the help of Myoware EMG based muscle sensor. Total 50 paralyzed cases were included in this study. Among the 50 cases of paralyzed patients, majority of the cases (55%) were of 40-55 years aged group where 75% were male and 25% were female. In this study, 85% were Localized paralyzed patients, 10% Partial paralyzed and 5% Complete paralyzed. This study also shows the condition of healthy biceps muscle as compared with paralyzed muscle. The findings of this study could play an important role to observe the condition of paralyzed muscle for better management of paralyzed patients and give a clear idea about which management is needed.
