A total of 1100 participants aged 50 years and older were included in this study. Kyphosis was determined using lateral CT images to determine the Cobb angle between T4 and T12. Multiple performance-based tests of physical function were used, alongside a questionnaire to determine self-reported physical function. Participants were divdided into four quartiles (Q1-Q4) based on Cobb angle, with Q4 representing the most excessive kyphosis. The study findings showed no difference in walking speed, grip strength, chair stand time, and frequency of self-reported physical impairment between women or men, with and without excessive kyphosis, younger or older than 65.
