The purpose of this study was to investigate spinal column mobility, trunk muscle mass, and the prevalence of lower back pain in young adult women with Generalized Joint Hypermobility (GJH), and to determine their impact on lower back pain. Physical characteristics associated with trunk muscle mass and spinal mobility were evaluated in 125 female students at a Japanese medical university.The study participants were categorized into the GJH, limited joint hypermobility (LJH), and non-GJH groups according to their Beighton scores, and an intergroup comparison of the variables was performed. The proportion of participants with GJH was 36.0%. A three-group comparison revealed that entire spine extension, and entire spine flexion mobilities were significantly high in the GJH group, whereas no significant differences were found in the prevalence of low-back pain or trunk muscle mass. These findings indicate that young adult women with GJH had excessive spine mobility, but no decrease in trunk muscle mass or increase in the prevalence of low back pain, suggesting that GJH has little effect on low back pain.
