Reliability study of the Pectoralis Minor Muscle Thickness Measurement using Rehabilitative Ultrasound Imaging

Abstract

This study examined the imaging procedure of pectoralis minor muscle thickness and assessed the intra-and inter-rater reliability of the muscle thickness measured by two raters using rehabilitative ultrasound imaging (RUSI) in healthy individuals. METHODS:Fifteen participants (aged 21 -28, seven females, and eight males) were involved in the study. The primary rater palpated the coracoid process and the fourth rib, defined as the width of the index finger lateral to the sternum to avoid breast tissues, and lined the two landmarks. The second examiner checked 1 / 3 (1st point) and 1 / 2 (2nd point) of the line length as measurement points. The two raters obtained right side muscle images of the participants at a standardized sitting position using RUSI with a 7.5 MHz linear transducer at 40mm depth. For intra-rater reliability, the principal rater took three images per point and tried to take one more with an interval. For the inter-rater reliability, the other rater performed the same tasks as the principal rater on the

Comparison of the Respiratory Muscle Thickness and Lung Capacities during Stairs Up-Down between Individuals with and without Smoking

“…With the subject seated in a comfortable position, the probe was placed on the transverse axis of the pectoralis minor muscle and an image was obtained at the end of exhalation to minimize the effect of respiration and muscle contraction. 14 The length of the pectoralis minor muscle was measured at the center of the ultrasound screen. In order to minimize error, the average value, which was measured three times, was used as the data value (Figure 3 and 4).…”

Effects of a Sling and Gym Ball Exercise Program on Postural Alignment and Lung Function in Adults with Forward Head Posture: A Randomized Controlled Trial

“…전방 머리 자세를 개선시키는 물리치료 중재 중 안정 화 운동(stabilization exercise)은 경추 장애 환자의 경추 움직임을 조절하고 심부 근육을 강화한다 [10]. 이를 통 해 신체 균형의 향상과 경추의 올바른 정렬이 가능하게 되고, 전방 머리 자세와 둥근 어깨 자세로 인한 어깨뼈 근육들의 불균형을 효과적으로 회복할 수 있다 [11].…”
