Sitting stability is maintained by continuous and intermittent activation of trunk and lower limb muscles. However, spinal cord injury (SCI) can result in paralysis of the trunk muscles and affects sitting balance. Currently, chest straps and trunk braces are used to correct sitting after SCI. In addition to these passive devices, functional electrical stimulation (FES) could be used to artific...

BACKGROUND A Swiss ball is often incorporated into trunk strengthening programs for injury rehabilitation and performance conditioning. It is often assumed that the use of a Swiss ball increases trunk muscle activity. The aim of this study was to determine whether the addition of a Swiss ball to trunk bridging exercises influences trunk muscle activity. METHODS Surface electrodes recorded the...

STUDY DESIGN An experimental design to investigate activation patterns of trunk muscles during multidirectional exertions. OBJECTIVES To evaluate trunk muscle activation patterns in varying directions and moment magnitudes during an isometric task, and to investigate the effects of angle and level of isometric exertion on the electromyography (EMG) variability of trunk muscles in upright post...

Vascular responses in the large central pad of the dog's foot were recorded during stimulation of the lumbosacral sympathetic trunk and correlated with the site of stimulation and the subsequent histologic analysis of the excised trunk. The resulting description of the preganglionic inflow and postgaiiglionic outflow from the trunk demonstrated marked variations in the anatomic patterns of the ...

1 During gait, the trunk and neck are believed to play an important role in dissipating the transmission 2 of forces from the ground to the head. This attenuation process is important to ensure head control is 3 maintained. The aim of the current study was to assess the impact of externally restricting the motion of 4 the trunk and/or neck segments on acceleration patterns of the upper body and...

Abstract Purpose: Autism Spectrum Disorder (ASD( identified via deficit of social communication, stereotyped movements and limited interactions. Postural instability is common in children with autism spectrum disorder. The purpose of this study is the effects of 8 weeks core stability training on trunk endurance in boys with autism spectrum disorder. Methods: The research subjects include ...

As unexpected sudden unloading of the trunk may cause low-back injury, the objective of the present study was to investigate whether handle height and the expectation of cart movement in pushing affect trunk control at movement onset. Eleven healthy male participants pushed a 200-kg cart with handles at shoulder and hip heights. The cart would suddenly move when externally released (externally ...

A variation artery was observed in a Japanese cadaver. The celiac and superior mesenteric arteries arose from a common trunk (also referred to as the celiacomesenteric trunk), but not from the abdominal aorta, respectively. From the common trunk, the common hepatic artery was distributed in the right part of the liver, and the left hepatic artery arose from the left gastric artery, which also a...

Upright stance was perturbed using sinusoidal platform rotations to see how vestibular and somatosensory information are used to control segment and intersegmental dynamics in subjects with bilateral vestibular loss (BVL) and healthy controls (C). Subjects stood with eyes closed on a rotating platform (+/-1.2 degrees) for frequencies ranging from 0.01-0.4 Hz in the presence and absence of light...
