<![CDATA[Introduction: Trapezius myalgia is one of the musculoskeletal complaints frequently experienced by office workers due to prolonged static sitting and computer use. This study aimed to determine the effects of Self-Sustained Natural Apophyseal Glides (Self-SNAGs) and stretching exercises, as well as the differences in their effects on trapezius myalgia in office workers. Methods: The study employed an experimental method with a two-group pre-test and post-test design. A total of 38 office workers were selected using purposive sampling and allocated to two groups, each comprising 19 participants. The first group was given Self SNAGs, whilst the second group was given stretching exercises, each performed three times a week for two weeks. Changes in condition were measured using the Neck Disability Index (NDI) and analysed using a paired-sample t-test and an independent-sample t-test with α = 0.05. Results: The results of the study showed that the NDI score in the Self SNAGs group decreased from 14.79 ± 5.138 (pre-test) to 4.32 ± 3.001 (post-test), p<0.001, whilst the stretching exercise group’s score decreased from 15.26 ± 4.954 (pre-test) to 4.05 ± 3.325 (post-test), p < 0.001. A comparison of the post-test scores between the two groups revealed no significant difference, with 4.32 ± 3.001 in the Self SNAGs group and 4.05 ± 3.325 in the stretching exercise group (p = 0.799). Conclusion: Both interventions showed an improvement in NDI scores among the office workers who were the subjects of the study, but there was no significant difference in effect between the two.]]>
