Abstract: A biomechanical stabilizer apparatus and methods for strengthening unstable joints and improving muscle coordination is disclosed in one presently preferred embodiment of the present invention as comprising a tubing assembly incorporating a substantially circular member and an elongated handle member. In current design, the handle member extends substantially transverse dimensionally across the internal diameter of the circular member and is operably connected thereto. Preferably, the circular member is formed having an internal channel comprising two or more free moving bodies disposed therein. Similarly, the handle member is formed having an internal chamber wherein at least one free moving body is operably disposed. Preferably engaging the handle member is a timer unit for programming time durations and providing means for visual and/or audio feedback to the user when the programming parameters of the present invention are satisfied.
