My idea is a back brace. When I first looked up complaints that astronauts had in space, I saw that the all had back pains. Unlike Earth, there is no gravity in space to put a curve in their backs, therefore, their backs are straight, which causes back pain. This “support”, is meant to go in the lower-lumbar region of the back. Because it is only a ¼ of an inch thick, it is flexible. To use it, astronauts could take something a simple as some yarn, and tie it to the two holes, tighter or looser, depending on the needed curve for their spines. This can be used anywhere, but it is best used on the Treadmill with Vibration Isolation and Stabilization System (TVIS) /Combined Operational Load Bearing External Resistance Treadmill (COLBERT), the Cycle Ergometer with Vibration Stabilization System (CEVIS) , and the Advanced Resistive Exercise Device (ARED), because it can best simulate the feeling of being on Earth. Thank you for the time to view my submission, and I hope you consider me.
