Is Neck Posture Subgroup in Late Adolescence a Risk Factor for Persistent Neck Pain in Young Adults? A Prospective Study.

Objective: The purpose of this study was to determine whether sagittal neck sitting posture subgroup membership in late adolescence was a risk factor for persistent neck pain (PNP) in young adults.

Methods: There were 686 participants enrolled in the Raine Study at the 17- and 22-year follow-ups. At 17 years of age, posture was measured by photographs, and 4 subgroups of sitting neck posture were determined by cluster analysis.

Neck Posture Clusters and Their Association With Biopsychosocial Factors and Neck Pain in Australian Adolescents.

Background: There is conflicting evidence on the association between sagittal neck posture and neck pain.

Objective: The purposes of this study were: (1) to determine the existence of clusters of neck posture in a cohort of 17-year-olds and (2) to establish whether identified subgroups were associated with biopsychosocial factors and neck pain.

Design: This was a cross-sectional study.

The effect of different standing and sitting postures on trunk muscle activity in a pain-free population.

Study Design: A normative, single-group study was conducted.

Objective: To determine whether there is a difference in electromyographic activation of specific lumbopelvic muscles with the adoption of common postures in a pain-free population.

Summary Of Background Data: Clinical observations indicate that adopting passive postures such as sway standing and slump sitting can exacerbate pain in individuals with low back pain.
