Ankylosing Spondylitis
Description
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.
Format
A data frame with 78 observations on the following 7 variables.
- fbef
flexion angle before
- faft
flexion angle after
- rbef
rotation angle
before
- raft
rotation angle after
- grp
treatment group - a factor with levels control
treat
- side
side of the body - a factor with levels
right left
- person
id for the individual
