Movement pattern that we observed in the lower limbs during walking results from the interaction between external forces (joint reaction and ground reaction) and the internal forces (produced by muscle and other soft tissue ). Knowledge of the ground reaction force is especially helpful to therapists who must understand how muscle activity and timing contributes to stability and propulsion. Muscle activity is typically studied using electromyography (EMG). With electromyography (EMG) signal it is possible to track the intended movement even in the presence of obstacles or lack of sufficient muscle power. If the EMG sensors are placed carefully on the subject, the intension will be available ahead of time. The reason for this is that EMG signals are detectable slightly before the actual movement is performed, because muscle take some time to produce the force after having received the activation signal. EMG records differ between individuals, and differ for a single individual according to variables such as velocity.
