Background: Ou MC decrescendo phenomenon shows to be an intracorporeal interoceptive issues yielded by interactions of human body anatomical axes (HBAAs). Spatial awareness may contbutes the effect of interoceptive sensation by Ou MC decrescendo phenomenon [1].

Methods & Results: Ou MC decrescendo phenomenon exercise with left to right and dorsoventral axis interactions yields interoceptive issues which alleviates pain, causes cessation of uterine bleeding, improves organ dysfunction, depresses malignancy of cancer. Three-dimension is more effective than two-dimension HBBAs interactions [1]. Nonetheless, the interoceptive sensation by the spatial awareness meditation (walking or mirror) of the spatial schema of human body also showed to improve muscular phasic activity, postural coordination and stiffness for locomotive deterioration of aged patients [2,3].

Discussions: The effect of Ou MC decrescendo phenomenon is related to the interactions of HBBAs which yield anti-inflammatory reaction in our studies [1]. While the patients perform Ou MC decrescendo phenomenon exercise, the interactions of HBBAs apparently cause an intracorporeal spatial awareness and yield interoceptive sensation. Nonetheless, the spatial awareness by meditation for the schema of human body also yields interoceptive sensations with similar effect [2,3]. Probably, a spatial awareness by meditation is related to HBBAs of the schema of human body. Further studies are warranted.
