Fig. 1From: Intra- and inter-rater reliability of rectus femoris muscle thickness measured using ultrasonography in healthy individualsUltrasonography set-up in the measurement of skeletal muscle thickness. a Participant is depicted in a supine position while the user holds the ultrasound probe against the anterior surface of the thigh. b The exact position of the probe is illustrated. Muscle thickness was determined from the resulting ultrasound images, and the values from two independent raters were used to decipher the intra- and inter-rater reliabilitiesBack to article page
