Journal ArticleDOI
Prevalence and distribution of intervertebral disc degeneration over the entire spine in a population-based cohort: the Wakayama Spine Study
Masatoshi Teraguchi,Noriko Yoshimura,Hiroshi Hashizume,Shigeyuki Muraki,Hiroshi Yamada,Akihito Minamide,Hiroyuki Oka,Yuyu Ishimoto,Keiji Nagata,Ryohei Kagotani,Noboru Takiguchi,Toru Akune,Hiroshi Kawaguchi,Kozo Nakamura,Munehito Yoshida +14 more
TL;DR: The baseline data of DD over the entire spine in a large population of elderly individuals are established and provide the foundation for elucidating the causes and mechanisms of DD.
Journal ArticleDOI
The association of combination of disc degeneration, end plate signal change, and Schmorl node with low back pain in a large population study: the Wakayama Spine Study
Masatoshi Teraguchi,Noriko Yoshimura,Hiroshi Hashizume,Shigeyuki Muraki,Hiroshi Yamada,Hiroyuki Oka,Akihito Minamide,Hiroyuki Nakagawa,Yuyu Ishimoto,Keiji Nagata,Ryohei Kagotani,Sakae Tanaka,Hiroshi Kawaguchi,Kozo Nakamura,Toru Akune,Munehito Yoshida +15 more
TL;DR: The data suggest that DD alone is not associated with low back pain, and the combination of DD and ESC was highly associated with LBP.
Journal ArticleDOI
Progression, incidence, and risk factors for intervertebral disc degeneration in a longitudinal population-based cohort: the Wakayama Spine Study
Masatoshi Teraguchi,Noriko Yoshimura,Hiroshi Hashizume,Hiroshi Yamada,Hiroyuki Oka,Akihito Minamide,Keiji Nagata,Yuyu Ishimoto,Ryohei Kagotani,Hiroshi Kawaguchi,Sakae Tanaka,Toru Akune,Kozo Nakamura,Shigeyuki Muraki,Munehito Yoshida +14 more
TL;DR: This 4-year longitudinal study is the first to demonstrate DD progression and incidence in the lumbar spine and their risk factors in a large population-based cohort.
Journal ArticleDOI
Prevalence of diffuse idiopathic skeletal hyperostosis (DISH) of the whole spine and its association with lumbar spondylosis and knee osteoarthritis: the ROAD study.
Ryohei Kagotani,Munehito Yoshida,Shigeyuki Muraki,Hiroyuki Oka,Hiroshi Hashizume,Hiroshi Yamada,Yoshio Enyo,Keiji Nagata,Yuyu Ishimoto,Masatoshi Teraguchi,Sakae Tanaka,Kozo Nakamura,Hiroshi Kawaguchi,Toru Akune,Noriko Yoshimura +14 more
TL;DR: This cross-sectional population-based study clarified the prevalence of diffuse idiopathic skeletal hyperostosis in general inhabitants and its significant association with lumbar spondylosis and severe KOA.
Journal ArticleDOI
Quadriceps muscle strength, radiographic knee osteoarthritis and knee pain: the ROAD study
Shigeyuki Muraki,Toru Akune,Masatoshi Teraguchi,Ryohei Kagotani,Yoshiki Asai,Munehito Yoshida,Fumiaki Tokimura,Sakae Tanaka,Hiroyuki Oka,Hiroshi Kawaguchi,Kozo Nakamura,Noriko Yoshimura +11 more
TL;DR: Quadriceps muscle strength and weight bearing index (WBI) were significantly associated with knee pain after adjustment for age and body mass index, whereas grip strength and muscle mass at the lower limbs were not.
