  • Patent number: 9975028
    Abstract: A therapeutic striking and rehabilitation training system that provides rehabilitation and therapeutic training in a home environment for persons with disabilities from an accident, wounded veterans, from disabilities involving birth defects, or as part of a physical therapy program even for bed-ridden patients. A therapeutic striking and rehabilitation training system also improves conditioning and hand-eye coordination which is attached to a ceiling, or hung in a door opening using a bar, via a tether with a ball attached to the end of said tether. The ball is a given distance from the ceiling as determined by the user. Once the desired distance has been chosen, the user then strikes the ball with enough force for the ball to contact the ceiling and then begin a downward trajectory towards the user to be struck again.
    Type: Grant
