Abstract: (90 Views)
Background: Extended use of smartphones can result in improper neck posture, leading to an increased risk of neck injuries. Inappropriate neck postures using smartphones can decrease deep neck flexor endurance and weaken neck proprioception. This study examines the impact of three different neck postures on neck proprioception and deep neck flexor endurance while using a smartphone.
Methods: This cross-sectional study was conducted at Hamadan University of Medical Sciences, Hamadan, Iran, in 2023. A total of 75 students from Hamedan University of Medical Sciences were divided into three groups of 25 individuals each, each group having a different posture. The neck proprioception was checked using the joint position error test, while the deep neck flexor endurance test was used to evaluate the endurance of deep neck flexors. The data obtained were analyzed using SPSS software.
Findings: Subjects who maintained a hyperflexed posture while using a mobile phone had weaker neck proprioception and lower endurance in deep neck flexors than those with other postures (P < 0.001).
Conclusion: When utilizing a mobile phone, maintaining a hyperflexion posture for the neck may lead to more detrimental effects on neck proprioception and deep neck flexor endurance compared to other neck postures. Smartphone users should maintain a neck posture with the lowest flexion angle while using this device.
