Background and Purpose: Changes of the alignment of either the scapulae or the cervical spine can potentially influence the biomechanics of the other by altering the tension at the cervico scapular muscles. This can lead to neck pain decrease cervical range of motion and difficulty in activity of daily living. The purpose of this study is to see the role of scapular posture on cervical rotation range of motion with Smartphone in healthy adult this will help in design appropriate assessment and management protocol for improvement of cervical rotation range of motion. Methods: Total number of subject 80 was taken in this research, Group 1 (Group NS for the people with neutral scapular alignment) contains 40 subjects, and Group 2 (Group DS for people with depressed scapular alignment) contains 40 subjects. Data Analysis: In this study SPSS 15 software was used to analyze the data. The independent variables was group (DS and NS) .A two way mixed model analysis of variance (ANOVA) was performed to test for the interaction of group and positions and to test for the main effects of group and position Results: There is no significant difference in total cervical rotation (right + left) for subjects having neutral or depressed scapular alignment.
