Editorial Note

Motor control may be a complex process involving the coordinated contraction of muscles thanks to the transmission of impulses sent from the motor area to its motor units. It’s the process of initiating, directing, and grading purposeful voluntary movement. It’s a topdown process of the nervous system that happens before the particular movement is performed, that appropriately adjusts for force, tone and timing. During the intended movement goal, the nervous system continues to assess its performance and adjusts force, timing and tone accordingly with sensory information from proprioceptors, visual and vestibular systems. This information that's obtained is often stored from future performance of an equivalent task. If this is often then repeated, a replacement skill is often learnt. The aim is to scale back the cognitive demand during a skill or task i.e. learning to drive and talk at an equivalent time. control Theories include production of reflexive, automatic, adaptive, and voluntary movements and therefore the performance of efficient, coordinated, goal-directed movement patterns which involve multiple body systems (input, output, and central processing) and multiple levels within the nervous system. As therapists we will change the environment, or the task in such how on enable our patients to realize their goals. Motor control is that the regulation of movement in organisms that possess a nervous system. Control includes reflexes also as directed movement.

To control movement, the nervous system must integrate multimodal sensory information and elicit the required signals to recruit muscles to hold out a goal. This pathway spans many disciplines, including multisensory integration, signal processing, coordination, biomechanics, and cognition, and therefore the computational challenges are often discussed under the term sensorimotor control. Successful control is crucial to interacting with the planet to hold out goals also as for posture, balance, and stability. Some researchers argue that control is that the reason brains exist in the least. A single efferent neuron and therefore the muscle fibers it innervates are called a motor unit. For instance, the rectus femora’s contains approximately 1 million muscle fibers, which are controlled by around 1000 motor neurons. Activity within the efferent neuron causes contraction altogether of the innervated muscle fibers in order that they function as a unit. Increases in nerve impulse frequency within the efferent neuron cause increases in muscle cell contraction, up to the maximal force. The maximal force depends on the contractile properties of the muscle fibers. Within a motor unit, all the muscle fibers are of an equivalent type and motor units of multiple types structure a given muscle. Motor units of a given muscle are collectively mentioned as a fleet .The force produced during a given muscle thus depends on: 1. what percentage motor neurons are active, and their spike rates; 2. the contractile properties and number of muscle fibers innervated by the active neurons. To get more force, increase the spike rates of active motor neurons and/or recruiting more and stronger motor units.

While synergies represent coordination derived from peripheral interactions of motor components, motor programs are specific, prestructured motor activation patterns that are generated and executed by a central controller). They represent at top-down approach to motor coordination, instead of the bottom-up approach offered by synergies. Motor programs are executed in an open-loop manner, although sensory information is presumably wont to sense the present state of the organism and determine the acceptable goals. However, once the program has been executed, it can't be altered online by additional sensory information

Evidence for the existence of motor programs comes from studies of rapid movement execution and therefore the difficulty related to changing those movements once they need been initiated. For instance, people that are asked to form fast arm swings have extreme difficulty in halting that movement when given a "STOP" signal after the movement has been initiated. This reversal difficulty persists albeit the stop signal is presented after the initial "GO" signal but before the movement actually begins. This research suggests that when selection and execution of a motor program begins, it must run to completion before another action is often taken. This effect has been found even when the movement that's being executed by a specific motor program is prevented from occurring in the least. people that plan to execute particular movements, but unknowingly have the action of their body arrested before any movement can actually happen, show an equivalent muscle activation patterns as once they are allowed to finish their intended action.
