Cognitive Trainer Matthew McNatt McNatt Learning Center, Inc. Cognitive Trainer Marseilles, IL 61341 "As the director of the McNatt Learning Center, Inc., I am excited by applications the Chi Machine may have to the field of cognitive training.    First, auditory discrimination can be hindered by decreased sensitivity to or awareness of lateral movement. By stimulating the vestibular system in an organized manner, the Chi Machine holds tremendous promise for enhancing auditory awareness, auditory discrimination, and vestibular integration. I thus view the Chi Machine as complimentary to listening therapy and balance training and, for some students, a helpful contribution to balance-based vision therapy using balance boards and Mardsen balls. Second, due to its bi-lateral rhythmic movement and possible enhancement of auditory discrimination, the Chi Machine can also be used as a warm-up for training gross-motor rhythm and timing. I thus view the Chi Machine as complimentary to training with the Interactive Metronome. Third, vestibular stimulation can be a primary gateway for teaching some hypo-stimulated children with special needs. I thus believe that the Chi Machine, when used in conjunction with naprapathic adjustment or Rolfing to help these children gain and maintain alignment, can be a key to helping some hypo-stimulated children " wake up " sufficiently to interact and learn. Fourth, adolescents and adults with Tourette syndrome (TS) often have heightened neuro-electrical awareness, along with a tendency to try to overcome what they perceive to be blockages in the flow of whatever internal energy they perceive. Movements to overcome perceived blockages, though often made in ignorance and ultimately unsuccessful, can become quickly habituated as " tics. " Children with TS usually tic without perceiving a cause. The oxygen rush of the Chi Machine mimics (or duplicates) the healthy flow of energy sought by many individuals with TS. Thus, individuals with TS may naturally trust the movement of the Chi Machine, which I believe they can then productively use as training, simply letting the movement happen instead of anticipating and trying to control it. Such practice waiting and letting go may be especially helpful for individuals with Tourette Syndrome in tandem to Interactive Metronome training, in which trainees similarly learn to wait for a beat, rather than anticipating or trying to control it. I personally use and enjoy the Chi Machine, and I heartily endorse its appropriate, supervised use in cognitive training."
