Since the contributions of the passive elements are negligible in the considered range of motion, only the contributions of the active elements are presented. The numbering of the bundles is performed using the following convention: serratus anterior, three bundles from caudal to cranial; trapezius scapular, three bundles from cranial to caudal; deltoid scapular, 11 bundles from lateral to medial. The humeral elevation in the x-axis is described with respect to the thorax. Date of download: 5/10/2017 Copyright © ASME. All rights reserved.

Since the contributions of the passive elements are negligible in the considered range of motion, only the contributions of the active elements are presented. The numbering of the bundles is performed using the following convention: deltoid scapular, 11 bundles from lateral to medial; deltoid clavicular, four bundles from lateral to medial.

The numbering of the muscle bundles is performed using the following convention: pectoralis major (PMJ), three bundles from cranial to caudal; latissimus dorsi (LTD), three bundles from cranial to caudal; deltoid (DLT), the first four bundles correspond to the clavicular part, ordered from the most medial to the most lateral fibers, and the last 11 bundles correspond to the scapular part, ordered from the most medial to the most posterior fibers; teres major (TMJ), one bundle; teres minor (TMN), three bundles; coracobrachialis (CRCB), one bundle; biceps brachii (BB), bundles one and two correspond to the long and short head, respectively.

As in most studies in the literature, the scapula was considered fixed during the elevation of the arm. Positive moment arms assist the elevation of the arm, whereas negative moment arms oppose it. The numbering of the muscle bundles is performed using the following convention: pectoralis major, three bundles from cranial to caudal; latissimus dorsi, three bundles from cranial to caudal. The first bundle of pectoralis major corresponds to its clavicular portion, while the remaining bundles correspond to its thoracic portion, ordered from cranial to caudal. The bundles of biceps brachii correspond, by order, to the long and short heads, respectively. Date of download: 5/10/2017 Copyright © ASME. All rights reserved.

The compressive and shear components of the reaction forces, acting perpendicular and along the plane of the glenoid, respectively, are represented in the right column.

The clavicular bundles are represented by black lines, while the scapular bundles are represented by yellow lines. As a whole, the bundles of the deltoid are sequentially ordered from 1 to 15 from anterior to posterior. Date of download: 5/10/2017 Copyright © ASME. All rights reserved.

As in most studies in the literature, the scapula was considered fixed during the elevation of the arm. Positive moment arms assist the elevation of the arm, whereas negative moment arms oppose it. The first four bundles, from 1 to 4, correspond to the clavicular part of the deltoid, ordered from the most medial to the most lateral fibers, and the last 11 bundles correspond to the scapular part of the deltoid, ordered from the most medial to the most posterior fibers.
