Purpose e/' the study: The present study was conducted to investigate the effect of poor posture on cervical range of motion (ROM) in young subjects.
Methods: 120 subjects were divided into four groups of both sex (males and females) ranged in age from 18 to 30 years were assigned into four groups (A, B, C and D) of equal ntllnber•, 30 subjects for each group. Group (A) included 30 patients who had fonvard head posture (FHP) (with craniovertebral angle (CVA) less than 49 degrees), group (B) included 30 patients who had thoracic kyphosis (with flexicurve angle more than 45 degrees) and group (C) included 30 patients who had FHP (with CVA less than 49 degrees) and thoracic kyphosis (with flexicurve angle more than 45 degrees) and group (D) included 30 normal subjects.
Results: The obtained results of the present study indicated that a significant difference in ROM of flexion, extension, RT side bending, LT side bending, RT rotation and LT rotation when compared between groups (A and D), (B and D) and (C and D).
