Neuromuscular involves noise and variability as a natural part and it occupies various levels of system. However it has been reported that excessive neural noise can impair the motor control system and can disturb the neuromuscular system coordination. The problem of exacerbated noise in neural system is because of the damaged sensory input. There is a disruption of body schema and the children with DCD thus suffer from poor perception and identification of self. Excessive neural noise will impact the ability of motor system and thus the dynamics is affected. To excel in the movement efficiency, there is a need for good predictive control and which is fundamental for movement task performance and the children with developmental coordination disorder exhibits core defect in predictive control. There is reported high level of variability among tasks performed by children with DCD and the level of movement kinematics and kinetics of task differs. All the activities rely on feedback mechanism and these children experience slow processing of feedback loop and the motor task outcome reported in these children is much slower and the changes in the external environment affects the task. The current study examines the noise, variability in children with DCD in relation to motor task execution
