Abstract:
Two-dimensional methods have been used to compute trunk kinematic variables (flexion/extension, lateral bend, axial rotation) and X-factor (difference in axial rotation between trunk and pelvis) during the golf swing. Recent X-factor studies advocated three-dimensional (3D) analysis due to the errors associated with two-dimensional (2D) methods, but this has not been investigated for all trunk kinematic variables. The purpose of this study was to compare trunk kinematic variables and X-factor calculated by 2D and 3D methods to examine how different approaches influenced their profiles during t

Abstract:
Translation and bend of the spine in the sagittal plane during high-speed quadruped running were investigated. The effect of the two spine motions on slip between the foot and the ground was also explored. First, three simplified sagittal plane models of quadruped mammals were studied in symmetric bounding. The first model’s trunk allowed no relative motion, the second model allowed only trunk bend, and the third model allowed both bend and translation. Next, torque was introduced to equivalently replace spine motion and the possibility of foot slip of the three models was analyzed theoretical

Abstract:
The role that the hypaxial muscles play in locomotion has been largely ignored by biologists. In tetrapods, there are at least three possibilities. First, the hypaxial muscles might bend the trunk laterally to increase stride length. Second, they might stabilize the trunk against the horizontal, lateral and vertical components of the propulsive force. Alternatively, they might not be involved in locomotion. This study evaluated these three hypotheses by analyzing the activity of the hypaxial muscles of green iguanas (Iguana iguana). During walking, the rectus abdominis, obliquus externus super

Unexpectedly, adult mutants with silenced fast muscles showed robust C-bends and forward propulsion upon stimulation. Retrograde

Transportation of oil via main pipelines often requires the need for a permanent or periodic dumping of some part of the flow for further shipment of crude oil to oil refineries or filling stations. The application of such technology leads to a change in the operating mode of oil pumping stations and the oil transportation system in general. In case of emergency, an analogue of dumping is an oil leak from the pipeline in a case of violation of its integrity. Resetting a part of the flow is accompanied by a change in a liquid flow ahead of and behind the discharge point, which inevitably leads

The condition begins in early puberty, affects 1-3% of adolescents, and randomly affects young women. Scoliosis screening is still a hot topic discussed by various researchers, especially in the school child population, and it is still an important preventive program to reduce the progression of spinal deformity. This study aims to determine the prevalence rate angle of trunk rotation in idiopathic scoliosis school screening in Surabaya. Methods: This res

Abstract:
Fish fast-starts are rapid events caused by the simultaneous onset of muscle activity along one side of the body. Spine curvature and the strain and electromyographic activity in white muscle were measured for fast-starts in the common carp Cyprinus carpio. The first bend of the fast-start was powered by muscle on the concave side: muscle fibres on this side were activated and began shortening simultaneously between the length-specific longitudinal sites 0.3L and 0.56L, where L is total body length. However, there was an increasing delay in the timing of the first peak in body curvature and mu

Abstract:
The Hip and Lower Limb Movement Screen (HLLMS) was developed to detect altered movement patterns and asymmetry specifically related to hip, pelvic, and lower limb movement control, as the other tools, such as the Functional Movement Screen (FMS), lacked focus on the hip and pelvic area. Both screening tools contain symmetrical and asymmetrical motor tasks which are based on observation of different aspects of each task performance. One motor task is in both screening tools. Therefore, they have some common features. The present study aimed to assess the relationship between the HLLMS and FMS p

SUMMARY The function of the lateral hypaxial muscles during locomotion in tetrapods is controversial. Currently, there are two hypotheses of lateral hypaxial muscle function. The first, supported by electromyographic (EMG) data from a lizard (Iguana iguana) and a salamander (Dicamptodon ensatus), suggests that hypaxial muscles function to bend the body during swimming and to resist long-axis torsion during walking. The second, supported by EMG data from lizards during relatively high-speed locomotion, suggests that these muscles function primarily to bend the body during locomotion, not to res

This research aims to find out the best linear regression models that could relate the analytic kyphosis measurements of the SM with one or more PG parameters of body posture in adolescents with kyphotic posture.
