Background: The excessive use of hand-held mobile devices (HHMD) leads to a postural phenomenon known as text neck.
Objective: The aim of this paper is to discuss the anatomical, biomechanical and muscle activation changes within the cervical and thoracic regions associated with the sustained, forward, flexed neck posture, observed with excessive usage of hand-held mobile devices. Additionally, this paper examines the relationship of gender, as well as the effects of carrying backpack loads by youth, on this forward, flexed neck posture.
Objective: This study examined the effects of various backpack loads on elementary schoolchildren's posture and postural compensations as demonstrated by a change in forward head position.
Subjects: A convenience sample of 11 schoolchildren, aged 8-11 years participated.
Methods: Sagittal digital photographs were taken of each subject standing without a backpack, and then with the loaded backpack before and after walking 6 minutes (6MWT) at free walking speed.
