AbstractThis report addresses how to release the back pain and cephalad edema of astronauts under microgravity during space flight. To study on spinal response under microgravity simulation, an MRI (Magnetic Resonance Imaging) compatible spinal compression harness was developed. Three healthy male subjects were fitted with a spinal compression harness and placed supine in a MRI scanner. Longitudinal distance between T7/8 and L5/S1 discs decreased 5.6 mm with 50 percent BW (Body Weight) compression. Lumbosacral angle increased 17.2 degrees. To release back pain in space, therapeutic massage is strongly advised to maintain the proper spinal curvature and balanced muscle tonus.
