Two electrodes Ag/AgCl with a 20-mm inter-electrode distance (Miotrace[R] 100) were placed midline of the Anterior Deltoid (AD): 4.0 cm below the clavicle, parallel to the muscle fibers at an oblique angle to the arm, the Pectoralis Major Clavicular fibers (PMC): 2.0 cm below the anterior border of clavicle along the longitudinal axis that crosses the middle point of the clavicle, and the Pectoralis Major
Sternocostal head (PMS): 2.0 cm medial from the axillary fold, parallel to the muscle fibers via a marginal oblique angle with a reference electrode placed close to the right clavicle.
Rib hypermobility caused by weakness of costochondral,
sternocostal, or costovertebral ligaments is considered the primary underlying mechanism of slipping rib syndrome [2].
The EMG signals of the clavicular and
sternocostal pectoral, clavicular deltoid and triceps brachii long head.
Then, she was under regular surveillance without any sign of relapse till the 7[sup]th year in 2015; a tender mass was palpated at the right
sternocostal region.
Aortic arch begun at the level of the upper margin of the second
sternocostal articulation of the right side, and run upward to cross the trachea on the left side of the fourth thoracic vertebral level.
The patient underwent surgery, and an ischemic herniated transverse colonic segment and omentum, which passed to the right hemithorax through the right anterior
sternocostal defect (Morgagni's hernia) were detected.
Pectoralis Major is well described as a two-head muscle, according to its clavicular and
sternocostal heads [13].
It can also pass through a posterolateral defect of the diaphragm secondary to arrest in the closure of pleuroperitoneal canal and diaphragmatic defects at the
sternocostal and lumbocostal region as described by Leininger et al.
No identifiable intercostal muscle or tissue existed between the two rib segments from the
sternocostal junction to the midclavicular line (Fig.
Results: The RTG displayed significant (p[?]0.05) increases in FEV1, FEV1 /FVC1, latissimusdorsi strength, pectoralis major clavicular portion strength, pectoralis major
sternocostal portion strength and emotional and digestion HRQOL domains, while decreasing pectoralis minor strength on the left and social, body image and respiration HRQOL domains.
However, it is typically described as having two main heads: the clavicular head (CH) and the
sternocostal head (SH).
Having the upper arm horizontal best stretches the
sternocostal head of the pectoralis major; placing the hand/ forearm lower preferentially stretches the clavicular head of the pectoralis major; and placing the hand/forearm higher preferentially stretches the pectoralis minor.
