This machine can be used for testing all sorts of conditions in the human body. It uses wheels on the body and a chest belt for measuring one's heart rate. The RS232 output is particularly convenient. This also uses longer handrails and underarm materials with a seat. There are also options to use like a harness system and a slide flight.
