Background: The present study has been conducted with the aim of the effect of the simultaneous implementation of the dual task on the dynamic balance of people with forward head posture.
Methods: In this experimental study, 40 male students with forward head posture (having a craniovertebral angle less than 45 degrees) and 40 normal male students (having a craniovertebral angle greater than 55 degrees) were purposefully selected to participate in the present study. After familiarizing the participants with the test implementation conditions (dynamic balance with cognitive task and dynamic balance without cognitive task), each of the tests was performed three times, and between each performance, the subject rested for 30 seconds.
Results: The collected data were analysed by two-way analysis of variance. The results of this research shown that there is significant difference between the dynamic balance of the participants with forward head posture position and normal participants, and the participants with forward head posture statistically have weaker dynamic balance (P<0.05). We also found out that the implementation of the dual task (cognitive-balance) has a significant effect on the balance of both groups of participants with forward head and normal posture and statistically weakens the dynamic balance of participants with forward head posture and normal participants (P<0.05).
Conclusion: In general, the results of the research made it clear that the posture of the forward head posture will cause the loss and decrease of the stability of the person's posture. Also, in both groups of people with forward head and normal posture, performing a dual task leads to the weakening of postural stability.

- In today's world, mechanization of lifestyle has caused wrong postural habits, especially in the head and neck area.
- Forward head posture causes abnormal contractions and muscle imbalance
- The implementation of the dual task (cognitive-balance) weakens the dynamic balance of participants with forward head posture and normal participants.
- Forward head posture will cause the loss and decrease of the stability of the person's posture.
