In it, Christman teaches factory workers how their posture affects performance and safety. There's been a particular interest among equestrians and dancers. One person who found him just that way is Kansas City chiropractor Joe Ventura, owner of Ventura Designs, Inc., who developed software to analyze posture. After calculating the amount of head and shoulder tilt, the software can determine the angles of offset from the spine, and calculate the amount of force these put on the spine. People hunched over computer keyboards, factory machines or video games all day can develop poor posture that leads to pain, and as they age even develop a dowager's hump below their neck.
Women tend to have worse symptoms than men, in part because women's fashion shoes distort the spine.
Also, teenage girls are often self conscious of their breasts so they slump forward. We're our own island. Ventura persuaded Christman to create a short version of his video for distribution only to health care professionals who work with patients. By deleting the explanatory material but keeping the exercises, the new video is just 22 minutes long. It's distributed to practitioners as a companion piece to the software.
