Virtual reality addresses back problems

ATHENS, Ohio, June 2 (UPI) -- Researchers at Ohio University in Athens say they have developed virtual reality programs for diagnosing back problems.

The scientists say they hope to patent a software and equipment package that could be sold to schools for use in training osteopathic physicians, physical therapists and other medical practitioners.

The researchers said using their "Virtual Haptic Back" instructors can adjust to the type and seriousness of back problems - such as an out-of-position vertebrae or vertebrae abnormally stiff to rotation.

The system works by giving users the sensation of touching a human back.

Users see a three-dimensional image of a back on a computer screen. Through motor-driven finger cups suspended from mechanical arms, they can feel the texture and resistance of the skin and underlying bones.

The key to the system is a sophisticated and highly sensitive "haptic" interface, which allows users to feel simulated computer objects, said Bob Williams, professor of mechanical engineering.

Results of the research appear in the Haptics-e Electronic Journal and the Virtual Reality Society Journal.
