Over 700,000 children and adults suffer from [cerebral] palsy,a condition [characterized ] by crippling nerve and muscle [dysfunctions].It's one of the most widespread [lifelong] disorders in the United States.

A team of [physicians] at Harvard Medical School and [engineers] at Massachusetts Institute of Technology has [corrected] that.Three film cameras [recorded] the patient's walk from the front,side and [diagonally] in a new gait laboratory at the Children's Hospital Medical Center in Boston.Special [markers] label the various body parts for the cameras.At the same time,an electromyography [measures] the electrical activity in the muscles,and a [supersensitive] scale determines the exact [amount] of force put down by each foot.All the pictures and other information are fed into a [mini-computer] to analyze.
