Antropometrik Değerlendirmede Kas İskelet Sistemi Ultrasonografisinin Yeri

Abstract

The aim of the study was to define the relationship among anthropometry, ultrasonography (US), and bioelectrical impedance analysis (BIA) for body composition analysis and to reveal the role of US measurements in clinical practice. One hundred forty-five subjects (100 female, 45 male) were enrolled in this study. Demographic data was obtained and body composition was evaluated by anthropometric measurements (height, body weight, trunk and extremity circumferences, skinfold), BIA (fat mass, fat free mass, skeletal muscle mass index) and US (subcutaneous fat thickness, muscle thickness, fascicule length and pennation angle of gastrocnemius muscle). Grip strength and gait speed were measured for functional assessment. For fat evaluations, US measurements were found more predictable then skinfold thickness, when BIA was considered as the reference method. For fat free mass evaluations, US measurements were good predictors for men but not useful for women. As for skeletal muscle mass index, US was a better predictor for men, but not good for women. In all measurement methods, high accuracy rate was found in fat mass for women and muscle mass for the men. Grip strength was correlated with muscle mass in both genders. Gait speed was correlated with muscle mass in women, not in men. In conclusion, musculoskeletal US is a useful method for body composition assessment.
