The present semi-experimental research is an intervention research; And the research design is ‎pre-test and post-test with control group. 36 people in the age range of 20 to 35 years were ‎selected in a targeted non-random way with a forward head angle above 46 degrees. The ‎craniovertebral angle or CVA was used to measure the forward head angle. To quantify the ‎intensity of pain in people with neck pain, the Visual Analysis Scale was used. Two-way ‎analysis of variance and Bonferroni post hoc tests were performed at a significance level of ‎p≥0.05‎.

The results of the research showed that both training programs had a positive effect on forward ‎head posture and neck pain of these people (p=0.001). Also, the results of the research showed ‎that after 3 months of the follow-up period, the effectiveness of the exercises was still ‎significant (p=0.001).‎
