Background. Although there are frequent studies about normal range of thoracic kyphosis, there is still a controversy about the exact values of this curve. In nine reported studies on 10 to 20 years of age boys, the value ranged from 25.1° to 53.3°. Objective for the Study. The aim of the present research was investigation of normal ranges of thoracic kyphosis in school children in Kermanshah, western Iran. Methods. 582 male students aged 13 to 18 years old using cluster random sampling were recruited from schools in Kermanshah city, 97 students for each age. Thoracic curves were measured using the flexicurve method. Results. Mean thoracic kyphosis for whole population was 35.49° SD 7.83 and plus or minus two standard deviations ranged from 19.83° to 51.15°. It increased gradually from 13 to 16 and then there was a little decrease to 18 years. Mean values for each age (13–16) were 13 (34.41 SD 7.47°), 14 (34.86 SD 8.29°), 15 (35.79 SD 7.93°), 16 (36.49 SD 7.85°), 17 (35.84 SD 8.33°), and 18 (35.55 SD 7.07°). Conclusions. Our results are in agreement with previous reports and can be used as normal values for local and regional purposes.
