Table 2.

Shows average values of postural angles which were measured with no school bag, with school bag over shoulders equivalent to 18% of the body weight in standing and after dynamic activities in standing

Conditions	Cranio-vertebral angle (CVA) Mean (SD)	Cranio-horizontal angle (CHA) Mean (SD)	Sagittal shoulder posture (SSP) Mean (SD)
Without school bag	40.62 (10.16)	20.51 (8.17)	39.39 (4.31)
With school bag (18% of body weight.) in standing	36.16 (10.5)	24.51 (10.30)	54.38 (21.19)
After dynamic activity with school bag (18% of body weight.) in standing	33.86 (7.96)	28.93 (4.34)	77.62 (17.50)
