Assessment of core and lower limb muscles for static/dynamic balance in the older people: An ultrasonographic study

Abstract Background sufficient research has not been conducted to determine the role of core and lower limb muscles in providing balance in older people. Objective to investigate the relationships between the thickness of core/lower limb muscles and static/dynamic balance in older people. Methods the study included a total of 68 older people (≥ 65 years) and 68 gender-matched young subjects, aged 20–40 years. Balance, knee proprioception sense, regional and total muscle measurements and grip strength were assessed using a force platform system, isokinetic dynamometer, ultrasound imaging, bioelectrical impedance analysis and Jamar dynamometer, respectively. Results all the static (postural sway) parameters were higher and all the dynamic (limits of stability) parameters were lower in the older adults compared to the young adults (all P
