forces generated in muscles through the application of the laws of motion from Newtonian mechanics. The movement is actively controlled by the motor commands generated in the central nervous system and sent to the musculoskeletal system through the descending tracts. These motor commands can be estimated with the electrical activities in the muscle tissue‚ which are recorded using electromyography (EMG) techniques. The activity of muscles as a function of time‚ also known as muscle activations provides

extension is the movement of straightening the leg at the knee joint. The major muscle involved in knee extension is the Quadriceps femoris‚ which is a group of four muscles.
