Brain Mapping of awake patients with Postural Deficiency Syndrome/ Proprioception Dysfunction Syndrome (PDS) present with higher values of absolute power (μv2) in the specific low frequency wave, the Delta wave, than the values of absolute power found in higher brain wave frequencies measured (Theta, Alpha, Beta1 and Beta 2) (Figure 1a). When wearing Active Prisms, the values of absolute power obtained for the Delta frequency become similar to those encountered in the other frequencies measured (Figure 1b).

The brain maps obtained indicate that the effect of the Active Prisms is not restricted to a specific area or areas of the brain, but that the effect is associated with a change in the specific low frequency wave, the Delta wave.  Brain mapping of PDS patients without and with Active Prisms suggests that PDS can be understood to be associated to perturbations of a particular frequency wave type (Delta wave).
