Is physical activity associated with bone geometry of premenarcheal girls in a dose-dependent manner?
Habitual PA affects geometry of both cortical and trabecular areas of a long bone of premenarcheal girls in a dose-dependent manner. Specifically, PA increases both the density and size of cortical bone but only the density of trabecular bone during preadolescence. Given the importance of peak bone mass for future fracture risk, high levels of PA during childhood could be a major target for public health interventions aimed at optimising bone health in prepubertal children when the greatest bone gains occur.
Neurological function improves more for patients with cervical spondylotic myelopathy diagnosed with myelopathy hand in early stage than those diagnosed conventionally without myclopathy hand. And an early diagnosis of this sign may boost the surgical efficacies for cervical spondylotic myelopathy.
