ABSTRACT:
An ergonomic support staff apparatus for supporting a user upon a surface is provided. The apparatus generally includes a longitudinally extended support member. The apparatus also includes a grip handle member adjustably coupled in position along the support member. The grip handle member includes a grip portion which protrudes laterally outward from the support member to extend in inclined manner relative to the support member. Use of the resulting apparatus enables the range of requisite arm swing motion for manipulation of the support member into stable engagement of the given surface to be minimized.
