Data from Royal Mineral Hospital in Bath. AS is a chronic form of arthritis. A study conducted to
determine whether daily stretching of the hip tissues would improve
mobility. 39 ``typical'' AS patients were randomly allocated to
control (standard treatment) group or the treatment group in a 1:2
ratio. Responses were flexion and rotation angles at the hip
measured in degrees. Larger numbers indicate more flexibility.
