Book Description
This book is about the ways which human behavior is affected concerns with people may be doing, their public impressions they typically prefer that No matter what else other people perceive them in certain desired ways and not perceive them in other, undesired ways. Put simply, human beings have a pervasive and ongoing concern with their self-presentations. Sometimes they act in ceflain ways just to make a particular impression on someone else mras when a job applicant responds inthat will satisfactorily impress the interviewer. But more often, people 5 concerns with others’ impressions simply constrain their behavioural options. Most of the time inclined to do things that will lead others to see us as incompetent, inwnoral, maladjusted, or otherwise socially undesirable. As a result, our concerns with others’ impressions limit what we are willing to do.Self-presentation almotives underlie and pervade near corner of interpersonal life.

Book Description
Locomotion involves many different muscles and the need of controlling several degrees of freedom. Despite the Central Nervous System can finely control the contraction of individual muscles, emerging evidences indicate that strategies for the reduction of the complexity of movement and for compensating the sensorimotor delays may be adopted. Experimental evidences in animal and lately human model led to the concept of a central pattern generator (CPG) which suggests that circuitry within the distal part of CNS, i.e. spinal cord, can generate the basic locomotor patterns, even in the absence of sensory information. Different studies pointed out the role of CPG in the control of locomotion as well as others investigated the neuroplasticity of CPG allowing for gait recovery after spinal cord lesion. Literature was also focused on muscle synergies, i.e. the combination of (locomotor) functional modules, implemented in neuronal networks of the spinal cord, generating specific motor output by imposing a specific timing structure and appropriate weightings to muscle activations. Despite the great interest that this approach generated in the last years in the Scientific Community, large areas of investigations remain available for further improvement (e.g. the influence of afferent feedback and environmental constrains) for both experimental and simulated models. However, also supraspinal structures are involved during locomotion, and it has been shown that they are responsible for initiating and modifying the features of this basic rhythm, for stabilising the upright walking, and for coordinating movements in a dynamic changing environment. Furthermore, specific damages into spinal and supraspinal structures result in specific alterations of human locomotion, as evident in subjects with brain injuries such as stroke, brain trauma, or people with cerebral palsy, in people with death of dopaminergic neurons in the substantia nigra due to Parkinson’s disease, or in subjects with cerebellar dysfunctions, such as patients with ataxia. The role of cerebellum during locomotion has been shown to be related to coordination and adaptation of movements. Cerebellum is the structure of CNS where are conceivably located the internal models, that are neural representations miming meaningful aspects of our body, such as input/output characteristics of sensorimotor system. Internal model control has been shown to be at the basis of motor strategies for compensating delays or lacks in sensorimotor feedbacks, and some aspects of locomotion need predictive internal control, especially for improving gait dynamic stability, for avoiding obstacles or when sensory feedback is altered or lacking. Furthermore, despite internal model concepts are widespread in neuroscience and neurocognitive science, neurorehabilitation paid far too little attention to the potential role of internal model control on gait recovery. Many important scientists have contributed to this Research Topic with original studies, computational studies, and review articles focused on neural circuits and internal models involved in the control of human locomotion, aiming at understanding the role played in control of locomotion of different neural circuits located at brain, cerebellum, and spinal cord levels.

Book Description
An essential resource for bodyworkers, physical therapists, and sports medicine practitioners--a vital guide to understanding the anatomy, form, and mechanics of the human foot. Understanding the Human Foot is a full-color, up-to-date overview of the structure and function of the foot, written for physical therapists and movement practitioners looking to deepen their understanding of holistic anatomy. Readers will gain perspective on the impacts of foot shape; the interdependence of form and function; and the cellular processes that determine how our tissue is designed. Most importantly, author James Earls demonstrates how the foot relates to and interacts with the rest of the body during movement, laying the groundwork for a comprehensive holistic approach to assessing, troubleshooting, and addressing functional and structural foot issues. Starting with big-picture questions--what is a foot, and what is it used for? How does it work, both on its own and as part of a whole?--before zeroing in on the 26 bones, 33 joints, and many muscles that make up the foot, Earls teaches anatomy the way he wishes he'd been taught 30 years ago: with a holistic emphasis on interrelated systems, real-life applications, and approachable, easy-to-understand language. He shares: Full-color illustrations for easy reference and comprehensive understanding An overview of the bones, ligaments, and extrinsic and intrinsic muscles of the foot How your gait impacts the rest of the body--and can cause problems as high up as the neck and shoulders How to assess structural problems of the foot Corrective exercises A footwear guide to choosing the best shoe for your foot type

Book Description
The basic understanding of human movement and control of human movement stems largely from laboratory measurements where human movement can be quantified with high precision and accuracy, but where the artificial environment compromises ecological validity. A good example for this issue was demonstrated in a recent investigation; specifically that the walking gait pattern of healthy individuals in a laboratory changed as a function of how many researchers were present during the experiment. Observations like these underscore that study volunteers adapt their behavior to the specific laboratory environment and warrant the question of how well we can transfer our lab-based understanding of gait patterns and the underlying neuromuscular control system to walking during daily living. Another research area where lab-based movement assessments have led to conflicting findings is the field of sports injury prevention: Many neuromuscular training programs have been shown to be effective in reducing the sport injury rate in athletes by 30-50% or more in a variety of different multi-directional sports. Nevertheless, lab-based assessments of the same athletes who completed those training programs were often not able to detect improvements in motor control of sport-specific movements or a reduction in joint loading, two factors thought to be closely linked with sport injury risk. This disconnect suggests that lab-based assessments of movement and motor control are often poor indicators of player behavior during real-game scenarios and may limit our ability to screen athletes for injury risk or monitor their progress in rehabilitation. These examples highlight that we should strive for the assessment and investigation of human movement and motor control in natural environments, i.e. where individuals, patients, athletes, or other groups of interest perform, explore, and interact under real-world conditions.

Book Description
Clinical Biomechanics in Human Locomotion: Gait and Pathomechanical Principles explores the clinical management of gait-disturbing or gait-induced pathologies and biomechanical variances during gait between individuals. The book discusses what is required to make terrestrial human locomotion safe and what causes pathology within a context of high locomotive and morphological variability. The interaction of genetics, epigenetics, developmental biology and physiology under the influence of locomotive biomechanics and metabolic energetics drives evolution. Such biological pressures on survival are essential in understanding the locomotive biomechanics of modern humans. In addition, lifestyle, including gait speed adaptability established during the growth influences of anatomical development is also considered. - Links human locomotive biomechanics to medicine, physiology, evolutionary anatomy and medicine - Prepares students, bioengineers and clinicians for the reality of utilizing biomechanical principles in clinical practice while also informing researchers of environmental limits - Includes further concepts in gait mechanics such as lower limb length, gait speed and how to calculate locomotive costs
