Background and Aim: Forward Head Posture (FHP) is one of the most common postural disorders which related to current life style. This disorder may cause some changes in motor control of cervical muscles.
Materials and Methods: Eight subjects with Forward Head Posture and 8 matched healthy subjects wereParticipated. The kinematic and electromyographic activity of each subject was analyzed and the flexion- Relaxation phenomenon was determined.
Results: The results showed that the cessation of flexion-relaxation phenomenon was different between two groups (P<0.05). The result of Pearson correlation showed a significant positive correlation between Cranio-vertebral angle and cessation of the phenomenon (P<0.05).
Conclusion: The flexion- relaxation phenomenon was different in Forward Head Posture related to the healthy subjects and the concentric contraction was started with delay in the Forward Head Posture subjects. Therefore, the motor control and balance disorder may be seen in these subjects.
