LOVETT scale is a parameter that commonly used by the doctor or therapist to determine the muscle strength of the patient's hands, especially post-stroke patients. By creating the system that combine desktop application with MYO armband, we can measure the muscle strength or the movement of patient's forearm including hands. MYO armband from thalmic lab can read the activities of human's hand muscles by placing it on forearm, as some requirement of LOVETT scalling process is muscles strength. The Myo armband has 8 EMG sensors, gyroscope, accelerometer and bluetooth connection for data transfer. we uses armband's data to control a virtual arm which was built in Unity 3D. this virtual arm can move based on MYO armband's sensors. As the arm moves the doctor can monitor the patient's activities from afar.
