Abstract

This invention pertains generally to non-invasive methods and apparatus for analyzing and improving human balance. More particularly, this invention describes a human balance analysis and improvement apparatus and method that involves the use of separate and synergistically integrated and combined means for analyzing and producing perfect core body alignment and balance: an alignment indicator, sway measurement apparatus, and foot force measurement and force centering apparatus. Data received from the aforesaid devices or various combinations thereof is then integrated and displayed by appropriate software and/or display apparatus for use in perfecting, analyzing and/or correcting human balance. The alignment and sway measurement apparatus of the invention is preferably subject based upon video motion capture technology. The foot force measurement and force centering apparatus is preferably based upon a pair of segmented force plates with underlying sensors capable of registering differences in distribution of weight on different parts of the segments.
