Lying on your stomach and holding your head up (such as a baby does) is very good for developing your vestibular sense. The vestibular system measures acceleration, g-force, body movements and head position. Swinging and spinning also develop this sense.
For children in need of deep sensory input, these are the shirts for you! SPIO clothing provides steady stretch tension directly to the skin and indirectly to the internal soft tissue structures—feeding the central nervous system. SPIO compression provides unparalleled, accurate deep pressure sensory information to feed proprioception resulting in improved positional limb and body awareness, core muscle and joint stabilization and increased precision of muscle activation and movement.
