The improvement seen in the study group I may be due to stepping practice via whole body vibration which strengthens and stabilizes the neural network involved in producing this pattern and improve the specific postural control mechanism needed to maintain the balance when transferring the weight from one leg to the other, so, treadmill as an example for stepping practice, facilitates and strengthens the neural connections that arise from the coupling of multimodal sensory input generated by the child through improving attention and awareness of the body position image in relation to his or her environment
