Ultrasound imaging for measuring muscle and subcutaneous fat tissue thickness of the anterior thigh: a 2 year longitudinal study in middle age

Abstract

Background Ultrasound (US) imaging technique is widely used in research and clinical settings to assess the morphology and morphometry of neuromusculoskeletal structures. The technique has reported validity and reliability in measuring the size of various muscles under controlled conditions. The aim of the present study was to assess anterior thigh thickness using US imaging , in a healthy cohort of middle-aged older adults. Methods Participants included 17 healthy older adults involved in regular moderate-vigorous activities (age range 39-66 years). US imaging scans of the anterior thighs 2 years since baseline measurements were performed. Images were
