The angle of kyphosis and scapulohumeral rhythm were measured by spinal mouse and goniometry respectively. Independent t test was used to analyze the data (<em>P</em><0.05).  The results showed a significant difference in motion of scapula, scapula rotation angle, range of humeral abduction and scapulohumeral rhythm between the two groups (<em>P</em><0.05). No Significant difference was observed in scapulohumeral rhythm between dominant and non-dominant hands in students with kyphosis (<em>P</em><0.05). The results showed that kyphosis can disturb scapulahumeral rhythm. In addition, kyphosis has the same effect on scapulahumeral rhythm in dominant and non-dominant hands. Therefore, it is recommended that students should correct kyphosis and strengthen shoulder girdle muscles based on corrective training protocols. https://sshr.ut.ac.ir/article_53805_1002b632ce735f65e245e879e90280bb.pdf
