hips

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.
