Posture, muscle endurance and ROM in individuals with and without neck pain

Abstract Introduction: Factors such as postural changes, reduced neck muscle endurance and reduced range of motion (ROM) are common characteristics attributed to people with neck pain. Objective: (a) Identify differences in postural, muscular endurance and ROM characteristics between individuals with and without neck pain and (b) relate the presence and intensity of neck pain with the characteristics of static posture, muscular endurance and cervical ROM. Method: A cross-sectional study with 60 subjects equally divided into two groups with respect to the presence of neck pain carrying out the following evaluations: (1) static postural evaluation by digital photogrammetry; (2) the neck flexor endurance test; and (3) evaluation of cervical ROM using a fleximeter. The data were analyzed with independent t-tests, the Mann-Whitney U test, and the Spearman and Tau of Kendall correlation tests (α
