Overview

Cross-sectional study reveals higher isometric neck muscle strength in men than women across six movement directions, indicating robust retention of cervical strength across aging.

Key Points

To quantify maximal isometric neck muscle strength in six different movement directions among healthy Chinese volunteers using a standardized multi-cervical evaluation device.
Standardized cross-sectional observational study conducted at a university rehabilitation unit evaluating 91 healthy volunteers aged 20–84 years.
Participants performed three consecutive maximal contractions per direction with 10-second rest intervals between contractions and 2-minute rests across six movement directions: flexion, extension, bilateral lateral flexion, protraction, and retraction.
Men demonstrated 1.2 to 1.7 times greater isometric strength across all directions compared with women (all p < 0.028), with right lateral flexion significantly exceeding left lateral flexion in men (p = 0.030) but not in women (p = 0.297).
No significant difference in cervical muscle strength was observed across age groups, and correlations between strength and height or weight were statistically insignificant in both sexes.
