Relation of Trunk Muscles Strength and Endurance to Severity of Forward Head Posturein Young Adults: An Observational Study

Abstract

Background and Objective: Forward head posture is the common habitual poor posture seen in young adults.This study correlates Trunk muscles strength and endurance with severity of forward head posture in youngadults.Methods: A total of 70 individuals with Forward Head Posture and Craniovertebral Angle (CVA) less than 480were enrolled in the study. The Trunk Muscle Strength was assessed using Hand Held Dynamometer. The Trunkflexor, extensor, side flexors and lower back extensors endurance was assessed using endurance tests. The trunkmuscle strength and endurance were then correlated with severity of forward head posture.Results: There was no correlation found between the trunk flexor strength and severity of FHP. But there wasstatistically significant correlation between the trunk extensor strength and severity of FHP. Also, no correlationwas found between the trunk muscles endurance and severity of FHP.Conclusions: Trunk Extensor muscles strength decreases with the decrease in CVA.
