The 'Stanford Score' was developed by Stanford University School of Medicine's Dr. Eugene Carragee (1) in 1997. It is based on the four quantitative ratings of the patients perception of how effective a treatment has been; in the 1997 research papers case, it was used to assess surgical outcomes. A rating of 0 represented a negative outcome, whereas 10 indicated a positive outcome. A rating of 8 or above is often used to indicate a successful outcome from a surgery or other procedure.
Sciatica pain: was rated such that 0 represented intolerably severe, constant pain, and 10 depicted a complete absence of sciatica.
A total score was then calculated to reflect these four ratings by adding each value from the afore-mentioned scales and dividing by four. This gives a total score from 0 to 10, with 0 indicating severe pain, daily narcotic intake, complete activity restrictions, and no satisfaction with outcome, and 10 indicating no pain, medications, or restrictions, and full satisfaction with outcome.
