Table 2. Functional outcome (Majeed and AAOS/MODEM) scores and health-related quality of life (SF-36) outcome scores from baseline to follow-up in surgical studies on treatment for chronic sacroiliac joint pain.*.
| Scoring system (component) | Preoperative score, mean ± SD | Follow-up | Score at follow-up, mean ± SD (range) | Improvement from baseline, % | |

Majeed scoring system was developed to assess functional outcome after pelvic injuries and is based on five criteria: pain (30 patients), standing (36 patients), sitting (10 patients), sexual function (4 patients), performance at work (20 patients) (0–00 points; lower score indicates worse functionality) [Khurana].
AAOS/MODEMS (American Academy/Association of Orthopaedic Surgeons/Musculoskeletal Outcomes Data Evaluation and Management System) is a modified Oswestry Disability Index scale and includes seven sections; lower score indicates greater disability [Buchowski, Longo].
SF-36 (Short-Form 36) measures quality of life in multiple domains, each domain with a maximum of 100 points (lower scores indicate greater disability); the Physical Component Summary is an aggregate of the Physical Functioning, Role-Physical, Bodily Pain, and General Health scales; the Mental Component Summary is an aggregate of the Vitality, Social Functioning, Role-Emotional, and Mental Health scales [Buchowski, Khurana]. Transformed scores reported; transformation not defined [Buchowski].
