Theories of Movement Control - Essay Example

Download file to see previous pages According to Schmidt and Wrisberg, there are at least two ways of conceptualizing the term 'motor skill' which can be construed as a talk or an act, where motor skills can be distinguishable along a number of aspects or on the basis of a variety of high-flying characteristics (Schmidt and Wrisberg, 2008). The second way construes to the conceptualization of motor skill in terms of the ability a person delineates while performing a movement. Utley and Astill, in their book, have stated that the motor skills can efficiently be implemented in the brain and nervous system as well and also that they can be improvised (Utley and Astill, 2008). The development in motor skills defines the field of measurement as well as movement, thereby, learning the ways to control movement as a whole. This paper delineates the contrasting nature of both the theories of motor control, i.e. the open-loop and the closed-loop theory, thereby, stating examples which demonstrate the different explanations of human coincidence-anticipation performance.

en loop system, the controller output indication is settled on by the input signal from the computer or any other non-essential device. In response to incorrect calculation of the system response, or the affect of some other occurrence in the output signal, the system might turn aside from the desired path. As a result, it is necessary for the controller to assume that each part of the system is at its absolute position and has moved there at the correct pace. No feedback is conceived from the system, which would enable the controller to weigh against the actual position to the programmed position. In such a case, it is not possible for the controller to check and correct himself. Under this kind of a system, it is feasible to incline against the designated positions and paces, and not be able to correct the difficulties.

This theory is significant for well-defined systems where the relationship between input and the resultant state can be modeled by a mathematical formula. For example, determining the voltage to be supplied to an electric motor which drives a consistent load, so as to acquire a desired pace can be considered as an appreciable implementation of open-loop control system. However, on the other hand, if the load were not predictable, the motor's pace might vary as an operation of the load as well as of the voltage. As a result, the open-loop controller would not be satisfactory enough to ensure the repeatable control of the speed.
