With the help of a three axes wireless acceleration sensor, the agonist biceps femoris muscle is contracted in real time, using a microcontroller based electrical muscle stimulator (EMS), at the instant when the acceleration of the tibia exceeds a limit value. The waveforms of the modulus of the three axes acceleration components and the EMS pulses applied to the right and left knees of a healthy subject, during the extension and flexion tests on the knee joint are presented simultaneously and discussed. It was observed that, the EMS pulses are generated with a delay of 40 msec and contracted the biceps femoris muscle successfully, at the instant when the acceleration limit is exceeded.eninfo:eu-repo/semantics/closedAccessanterior cruciate ligamentanterior translationknee braceacceleration sensorConference Object10.1109/tiptekno.2019.88952012-s2.0-85075596589392N/A389WOS:000516830900100N/A
