Scoliosis is a lateral curvature of the spine when the Cobb´s angle more than 10˚ on the frontal plane. Curve detection before skeletal maturation gives a good opportunity for early treatment or prevention of curve progression. Purpose of this study was to evaluate Adam's Forward Bend Test and Scoliometer HD in screening of Adolescent Idiopathic Scoliosis

The student was asked to stand erect, knees straight, feet at the same level and hands freely hanging.

They was observed from the back for shoulders, pelvic, and knees level. Student was asked to bend forward with his knees straight, feet together and hands freely and loosely hanged(Forward Bend Test).

Scoliosis was detected with rib cage rotation and hump appearance (positive test).

Absence of hump appearance means negative test. After Forward Bend, the students were screened using the Scoliometer HD Application.

The students were asked to bend forward with arms dangling and palms pressed together. The smart phone (Scoliometer HD) was placed on the student back with the central dark area in the application placed on the spinous processes of the lumber and thoracic regions to measure the angle of trunk rotation. Students with a scoliometer HD reading ≥7 degrees (≥20 ̊ Cobb's angle) were referred to orthopedic consultation and their parents were informed about the findings of the screening by the school manager and social worker.

Then the data were collected for statistical analysis
