Effect of Forward Head Posture on Dynamic Balance Based on the Biodex Balance System

Abstract

Forward Head Posture (FHP) results in spine malalignment, muscle imbalance and cervical proprioception sensory input impairment. Subjective description of FHP is interpreted differently by clinicians and therefore the FHP is classified as slight, moderate and sever. This study aimed to evaluate balance disorder in individuals with severe forward head posture (FHP). Twenty individuals with severe FHP and 20 controls were enrolled. Dynamic postural stability was assessed in all participants using the Biodex Balance System (BBS) in semi dynamic position with eye open/eye closed conditions. Based on the findings, dynamic postural stability in the sagittal plane was different between the groups (P<0.05). It can be concluded that impairment of dynamic postural stability occurs in individuals with severe FHP. The findings suggest that clinicians take into account the importance of dynamic postural stability assessment in FHP subjects and consider the application of intervention programs for improvement of the dynamic balance.
