The Low-Back Outcome Scale of Greenough and Fraser
Overview:
Greenough and Fraser developed the Back Outcome Score (LBOS) scale for measuring functional
outcome in a patient with low back pain. The authors are from Middleborough General Hospital in
England and Royal Adelaide Hospital in Australia.
Parameters:
(1) current pain from a 10 cm (or 100 mm) visual analogue scale (VAS)
(2) employment
(3) domestic chores or "odd jobs"
(4) sport or active social activities (like dancing)
(5) resting
(6) treatment or consultation with health care provider
(7) analgesia
(8) sex life
(9) sleeping
(10) walking
(11) sitting
(12) traveling
(13) dressing

where:             • The pain scale is a linear scale from 0 to 10 cm with 0 = no pain and 10 = worst
                   possible pain imaginable.
                   • The VAS score appears to have gaps (at 2-3 4 and 6-7 cm).
                   • For employment status housewives are according to previous abilities.
total score = SUM(points for all 13 parameters)
Interpretation: • minimum score: 0
                   • maximum score: 75
                   • The higher the score the better the patient's status.
