background: exercise is a widely prescribed treatment for chronic low back pain. the purpose of the present study was to investigate the effect of 8 weeks exercise on pain, disability and endurance of trunk flexor-extensor muscles in female with chronic idiopathic low back pain. methods: this clinical trial study has been done on 12 patients who referred to the arak city clinics. the function o...

In a stdudenet course of gross anatomy dissection at Kanagawa Dental College in 2006, we found an extremely rare case of the hepatic artery arising from the superior mesenteric artery of a 78-year-old Japanese male cadaver. This case belonged to type V in Adachi's classification of the celiac trunk and the superior mesenteric artery (1928). The gastro-splenic trunk and hepato-mesenteric trunk b...

The estimation of the position of the center of mass (CM) is essential in a wide range of biomechanical analyses. In horses, the majority of the body mass is contained in the trunk and in most studies, the trunk is assumed to be rigid. However, this rigidity assumption has not been tested. We quantified changes in the position of the trunk CM due to external shape changes by measuring the kinem...

Purpose The purpose of this study was to determine the effects of forced inspiration and forced inspiration and forced expiration exercise on stroke patients’ trunk muscle activity, trunk control ability. Methods Twenty four patients with stroke were randomly assigned to a control group with physical therapy and a complex breath exercise as well. The complex breath exercise group received physi...

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 ...
