caspian miniature horse is a rare small horse in iran. in this horse, brachiocephalic trunk originates from the craniodorsal of the convex part of the aortic arch. it supplies the head, neck, forelimbs and cranial part of the thoracic cavity. in this reseach topographical location of brachiocephalic trunk arising from the aorta and its ramifications have been studied. five caspian miniature hor...

Trunk muscle weakness and imbalance are risk factors for postural instability, low back pain, and poor postoperative outcomes. The association between trunk muscle strength and aging is poorly understood, and establishing normal reference values is difficult. We aimed to establish the validity of a novel portable trunk muscle torque measurement instrument (PTMI). We then estimated reference dat...

OBJECTIVE To review the literature that evaluates the influence of trunk motion on trunk strength and structural loading. BACKGROUND In recent years, trunk dynamics have been identified as potential risk factors for developing low-back disorders. Consequently, a better understanding of the underlying mechanisms involved in trunk motion is needed. METHODS This review summarizes the results o...

Until recently, growth stress studies have been made only on coniferous and dicotyledonous trees. Growth stress of trees is thought to be initiated in newly formed secondary xylem cells. This stress can accumulate for years and is distributed inside the trunk. Major characteristics of the trunk of monocotyledonous trees include numerous vascular bundles scattered inside the ground tissue and th...

STUDY DESIGN A split-plot experimental design was used to evaluate the influence of posture, trunk angle, and rotational velocity on peak torque output and myoelectric activity during maximal trunk extension maneuvers. OBJECTIVES To determine whether the kneeling posture alters extension torque capabilities in isometric and isokinetic exercises as compared with standing. Also, to ascertain wh...

Despite the intense focus on outcomes following an anterior cruciate ligament (ACL) reconstruction, it is not yet known whether unresolved abnormal hip and trunk neuromuscular control exists. The purpose of this study was to compare trunk and hip kinematics during running, hip abductor and external rotator strength, and trunk control between females who had undergone an ACL reconstruction and h...

INTRODUCTION Vascular patterns are important in the planning and performance of all upper abdominal surgical procedures. The coeliac trunk arises from the abdominal aorta and supplies the supracolic organs. Knowledge of variations of the coeliac trunk is important in procedures such as liver transplants for appropriate vascular ligation and anastomosis. METHODS The branching patterns of the c...

Trunk stiffness was measured in healthy human subjects as a function of steady-state preload efforts in different horizontal loading directions. Since muscle stiffness increases with increased muscle activation associated with increasing effort, it is believed that coactivation of muscles helps to stiffen and stabilize the trunk. This paper tested whether increased steady-state preload effort i...
