Mechanical loading apparatus having a signal modulating assembly

Abstract

A mechanical loading apparatus having an oscillating platform and a signal modulating assembly for modulating an operating signal of the oscillating platform for therapeutically treating damaged tissues, bone fractures, osteopenia, osteoporosis, or other tissue condition, as well as postural instability. The signal modulating assembly modulates the operating signal such that the oscillating platform oscillates at frequency which simulates human activities, such as, walking, jogging, running, stair climbing, etc. The mechanical loading apparatus further includes a control panel having control knobs or buttons for manually selecting a desired activity to be simulated by the mechanical loading apparatus.
