Abstract:
A voluntary contraction of muscles with one arm increases the excitability of corticospinal projections to the contralateral resting arm, a phenomenon known as crossed facilitation. Although many motor tasks engage simultaneous activation of the arm and trunk, interactions between corticospinal projections targeting these segments remain largely unknown. Using transcranial magnetic stimulation over the trunk representation of the primary motor cortex, we examined motor-evoked potentials (MEPs) in the resting erector spinae (ES) muscle when the contralateral arm remained at rest or performed 20

Abstract:
Recent research indicates that the sagittal plane moment arm of the erector spinae decreases at the L5/S1 level during torso flexion. The objective of this study was to assess the predicted L5/S1 spinal loading from a lifting task when allowing the erector spinae sagittal plane moment arm to vary during torso flexion. Nineteen male subjects lifted three loads from two origin locations to an upright neutral posture. Spinal loading was predicted from an EMG-assisted biomechanical model that allowed the erector spinae moment arm to vary during torso flexion. The predicted lateral, anterior-poster

A large body of research suggests arm extension and arm flexion to be indicators of automatically generated withdrawal and approach motivation, respectively. However, such a view has not remained unchallenged. Recent research suggests that the motivational significance of arm movements may be largely context dependent. The aim of this research was to demonstrate that an essential facilitating context factor for arm movements relies on the desirability of their expected outcomes.

AbstractThe elbow is a complex joint made up of three separate articulations within a common capsule. The proximal ulna articulates with the trochlea and functions as a hinge joint, while the proximal radioulnar joint provides for rotational movement of the forearm. The radiocapitellar joint allows for both hinge and rotational movements. Together, these allow for flexion and extension of the arm and, in conjunction with the distal radioulnar joint at the wrist, pronation and supination as well.

Abstract:
AbstractBeyond knowledge, critical thinking, new ideas, rigorous science and scholarly development, this chapter argues for the university as a space of life. Through the complexities and incommensurabilities of academic life, and drawing on Julia Kristeva’s notion of revolt, Emmanuel Levinas’ notion of Otherness, and Novalis’ concept of Romantisierung, it makes a philosophical argument for recognizing what might appear as uncomfortable transgressions of the marketable, measurable characteristics of World Class Universities. In various ways, the chapter asks where there is space, in the World Class University, for elements which may not overtly align with the neoliberal clamour for international recognition and esteem. In elevating everyday life in the university, the chapter blurs boundaries of the celebrated, strived for rankings with the spaces of life that are dark and heterotopic, messily entangled with histories, polyphonic human and more than human voice, beings and energies, within the university. Revolt provokes a re-turn to re-question the ethics and boundaries of treatments of ‘world’ and ‘class’ in conceptions of the World Class University. Here, ‘World Class University’ is not necessarily a globally streamlined and internationally bench-marked institution, flexing its socio-economic muscles in the face of the world. Instead, it is an institution that speaks for others who have been made silent and deprived of their own critical voice. It speaks for the suppressed and marginalized, and it speaks for the ones who are no longer with us, or who have not yet arrived. It speaks for the people and the times yet to come.

Abstract:
Preservation of astronaut crew health during an exploration mission to the Moon or Mars will be crucial to mission success. The likelihood of a life-threatening medical condition occuring during a mission to Mars has been estimated by NASA to be 1% per year (Johnston, 1998; Johnston, Campbell, Billica, &amp; Gilmore, 2004). Since basic life support is a vital skill in critical care medicine, plans must be in place for cardiopulmonary resuscitation in both microgravity and hypogravity (i.e., on the surface of the Moon or Mars). Following the design of a body suspension device to simulate a hypogravity environment, subjects performed external chest compressions in 1G, 0.17G (Lunar), 0.38G (Mars), and 0.7G (Planet X). Chest compression adequacy was assessed by means of rate and depth. Heart rate immediately before and after three minutes of chest compression gave a measure of rescuer fatigue. Elbow flexion was measured using an electrogoniometer in order to assess the use of arm muscles to achieve chest compressions. This study found that the mean depth (Lunar and Mars) and rate (Mars) of chest compression was below American Heart Association recommendations during hypogravity simulation in the female group. Furthermore, elbow flexion proved to be significantly greater during Lunar and Mars hypogravity simulation than that of the 1G control condition, suggesting that upper arm force may be used to counter the loss of body weight in an attempt to maintain adequate chest compression under these conditions.

Full text
Abstract:
Long latency reflexes (LLRs) are EMG activity occurring during the transition from reflex to voluntary motor activity, which probably arise from a transcortical loop, including afferents within the dorsal column/medial lemniscal system to the sensorimotor cortex and corticospinal tract efferents. Depending upon the site of a lesion and its pathophysiology, LLRs may be absent, delayed, or enhanced. In disorders of cortical hyperexcitability, including cortical myoclonus, an LLR occurring 40–60 ms after stimulation of the median nerve at rest may be present (“C-reflex.”) In response to noxious stimuli to the lower extremities, a polysynaptic network of spinal neurons, flexor reflex afferents, induce a patterned withdrawal response, including hip and knee flexion. These flexor reflexes may aid in the diagnosis of disorders of spinal cord hyperexcitability. Normally, following high stimulation of a peripheral nerve innervating a muscle that is being strongly contracted, no electrical activity occurs for approximately 100 ms (“silent period.”_ In disorders of distal peripheral nerve or muscle hyperexcitability, the silent period may be absent.

Abstract:
Patellofemoral (PF) disorders remain complex and multifactorial. PF pathology, such as PF knee pain, excessive lateral pressure, and PF arthritis have been linked to excessive contact forces and pressure between the patella and femur [1]. Antero-medial transfer of the tibial tuberosity and tibial attachment of the patellar tendon is a procedure that was designed to reduce the PF contact pressure, thereby decreasing pain symptoms of early PF arthritis. The transfer procedure alters the angle between the patellar tendon and the quadriceps muscle force, and increases the patellar moment arm. Thes

Abstract:
The goal of this study is to assess kinematic changes in the flexion pattern of a digit after resection of a single arm of the FDS tendon (ulnar superficialis slip resection or USSR). Angular joint displacement as a function of a controlled tendon excursion driven by computerized motors was used to quantify the kinematics of the finger. This series of experiments was performed on fresh-frozen cadaver hands, and data was acquired in real time using a National Instruments DAQ card and a PC running LabView software.

Abstract:
In musculoskeletal models of the cervical spine, muscles are often modeled as straight paths from origin to insertion [ e.g., 1]. However, muscle paths in the neck are constrained by bone and other soft tissues, and some studies have found that applying curvature to muscle paths improves anatomical accuracy [2; 3] and affects muscle parameters such as moment arm [3] and moment [4]. Currently, data available in the literature for neck muscle moment arms (MA) are sparse. In this study we estimated in-vivo moment arms using MRI-derived neck muscle paths modeled with curvature and those modeled as

Abstract:
Gait retraining techniques to reduce impact forces during running is of significant interest to clinicians interested in reducing running injury risk. Increased peak rectus femoris activity during swing was significantly correlated with decreased impact peak during running (r = −0.654, p = 0.01) due to the muscle’s large hip flexion moment arm (43 to 54 mm). Gluteus medius (r = −0.204, p = 0.466) and adductor longus (r = 0.104, p = 0.714) activity were not significantly correlated with impact peak. These results suggest that gait retraining programs aimed at reducing the impact peak during run

Abstract:
Over-automated equipments and modern city life style lead to the diminishing opportunities for muscle using; however, the comfortable life is not always good for human health, and appropriate muscle training can not only enhance muscular strength and endurance but improve the health and fitness. Different kinds of ideas have been proposed for muscle training by exercise machines, which control direction of resistance for safety sake but isolate specific muscle groups to be trained. Compared with machines, free-weight exercise is a whole-body training in which human limbs can be moved on differ

Abstract:
Studies of muscle moment arms have classically followed a method of superposition whereby the measurement or derivation of moment arm magnitudes at any given joint assume independence of the position of joints proximal to the joint under study. This is particularly important for muscles crossing multiple joints. However, because of the nature of the soft tissue anatomy that defines the paths of the intrinsic muscles of the hand inserting into the extensor hood (also known as the dorsal expansion), this assumption may not be true for the intrinsic muscle moment arms at the Proximal Interphalang
