چکیده
Background: Inappropriate head and neck alignment with change in other spinal cord segments can affect the function of the neck, trunk and back muscle groups. Objectives: The purpose of this study was to compare the endurance of neck and trunk muscles in peoples with and without forward head posture. Methods: In this case-control study, 67 students including 40 males (mean age 23 ± 1.5 years, mean height 173.16 ± 6 cm, mean weight 69.13 ± 8.69 kg) and 27 females (mean age 23.29 ± 3.31 years, mean height 162.65 ± 5.29 cm and mean weight 59.45 ± 7.04 kg) were randomly assigned to the study and divided into two groups of with and without forwards head posture based on craniovertebral angle measured through photogramography. Flexor muscle endurance, deep neck extension and transverse abdominal muscle endurance, flexors, extensors, and trunk flexor endurance were assessed. Results: The interaction between the presence of forward head posture and gender for the lower trunk extensor muscles was significant. It mean that the endurance of this muscle group was lower in men with forward head posture, but no difference was observed in women. The effect of forward head posture was significant in trunk flexor muscle endurance test (performed at 50 ° trunk flexion). Conclusion: Gender is an effective factor in the effects of forward head posture on trunk muscle endurance. In examining the complications of this postural disorder, it is advisable to pay attention to other spinal cord segments.
