Oswestry Dysfunction Index (ODI)
ODI is a self-evaluation scale for dysfunction of patients with low back pain. It consists of 10 aspects including pain degree, personal living ability (washing, dressing), lifting, walking, sitting, standing, sleep influence, sex life, social activities and travel. Each aspect covers 6 options, with points ranging from 0 to 5 points. The lowest score indicates no abnormal dysfunction, and the highest score indicates severe dysfunction. The corresponding candidate content scores are added up in turn according to the scores, and the percentage of the total score in the highest score (50 points) of all content is obtained, which is called the Oswe-stry dysfunction index.

Item Short Form Health Survey (SF-36)
SF-36 is currently one of the most widely used universal health-related quality of life measurement tools in the world. SF-36 covers 8 dimensions for assessing health-related quality of life and a total of 36 content items. Each dimension includes: physical function (PF), role physical (RP), bodily pain (BP), General health (GH), vitality (VT), social function (SF), role-emotional (RE) and mental health (MH). SF-36 first calculates the original scores of the eight dimensions, and then obtains the final score after corresponding conversion. The final score is 0-100 points. The higher the final score, the better the health of the testee.
