PMID 40535982WHAT IT FOUND
Female office workers with lower crossed syndrome type B sat with a more forward head, rounded shoulders, and flexed trunk for 30 minutes.
Some upper-body positions worsened by 20 minutes.
Key findings
01At baseline, 20 minutes, and 30 minutes of sitting, women with lower crossed syndrome type B had smaller craniovertebral angles than healthy women.
02At baseline, 20 minutes, and 30 minutes of sitting, women with lower crossed syndrome type B had smaller sagittal shoulder angles than healthy women and women with type A lower crossed syndrome.
03Women with lower crossed syndrome type B had lower trunk flexion angles than healthy women at baseline and 20 minutes, and lower than women with type A at baseline, 10 minutes, 20 minutes, and 30 minutes.

What it does not show
Only women were studied, so findings may not apply to men. The sitting task lasted 30 minutes, which the authors say may be too short to see posture change in healthy people or longer-term effects. Muscle activity was not measured with electromyography, so the study cannot identify changes in muscle activation during sitting. Discomfort or pain during sitting was not measured. The study did not explore the relationship between lower crossed syndrome and upper posture. Because it was cross-sectional and measured posture only, it cannot show that lower crossed syndrome type B caused the posture differences or that a treatment would help.
Declared interests
The authors declared no conflict of interest, and the research did not receive a specific grant from public, commercial, or nonprofit funding agencies.
The easy way to misread this
Do not read this as evidence that a treatment prevents discomfort or musculoskeletal disorders. The study measured posture during sitting and did not test an intervention, measure pain, or include men.
