A Study of Scapulohumeral Rhythm in Students with Kyphosis

Abstract

The aim of this study was to compare scapulohumeral rhythm between students with kyphosis and healthy students and between dominant and non-dominant hands in kyphosis students. 25 male healthy students and 25 male students of Arak University with kyphosis were selected by purposive sampling method. The angle of kyphosis and scapulohumeral rhythm were measured by spinal mouse and goniometry respectively. Independent t test was used to analyze the data (P<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 (P<0.05). No Significant difference was observed in scapulohumeral rhythm between dominant and non-dominant hands in students with kyphosis (P<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.
