Clinical Study on the Improvement of Adult Idiopathic Scoliosis by Sling Exercise Therapy Training Combined With Conventional Exercise Therapy

The Oswestry Disability Index (ODI) scale consists of 10 dimensions, such as walking, sitting, standing, and self-care ability. Each dimension is scored on a scale from 0 to 5 points, yielding a maximum total score of 50 points and a Minimum total score of 0 points. A higher score on the ODI indicates a more severe degree of functional impairment. The results of the ODI can be classified into four grades: a score range of 0%-20% suggests mild impairment; 21%-40% indicates moderate impairment; 41%-60% represents severe impairment; and 61%-100% reflects extremely severe functional impairment.

The Visual Analogue Scale（VAS） is a 0-10 scale, with 0 signifying no pain and 10 representing the most excruciating pain one can conceive. When administering the VAS, ensure that the graduated side of the scale is not visible to the patient. Then, ask the patient to mark the point on the ruler that reflects their current pain level. After that, the physician will assign a score according to the marked position. Based on the obtained score, pain can be classified as follows: a score of ≤3 indicates mild pain, 4-6 corresponds to moderate pain, and a score of ≥ 7 represents severe pain.

The Scoliosis Research Society-22 (SRS-22) questionnaire was employed to assess the QOL of patients. It evaluates quality of life across five dimensions: functional activities, pain, self -image, psychological state, and treatment satisfaction. Each item is scored from 1 to 5, and the total score, with a maximum of 110 and minimum of 0 , reflects a better QOL as it increases.
