This book addresses instruments, methodologies and diagnostic methods used to evaluate and diagnose human movement, locomotion and physical status in general.
Starting from historical perspective, the idea of understanding human locomotion by applying technical measurement devices and incorporating measurement data into physical representation of gross body movement is presented and explained, an approach known as inverse dynamics. With this approach as a kind of umbrella concept, components of measurement systems including relevant signal and data processing methods are described. Modern instruments to capture body movement by measuring its kinematics, kinetics and surface electromyography (sEMG) are thus described; all systems being used dominantly―if not exclusively―in a movement analysis laboratory setting.Focusing mainly on human posture and gait, but including also examples of movement patterns from selected kinesiological and sports activities, the book attempts to present essentials of biomechanics and biomedical engineering approach to this subject matter. It illustrates how data collected and elaborated by modern engineering technology can complement traditional expert knowledge of a kinesiologist or a medical doctor. The book is applicable in the fields of sports, physical activities, as well as in medical diagnostics and rehabilitation. The examples of this book’s practical application might be in evaluation of efficiency of human gait, in evaluation of skeletal muscle fatigue in physical exercise, in biomechanical diagnostics of traumatological conditions requiring orthopaedic treatment and the like.
This book can also be used in planning and executing research endeavours, particularly in a clinical context as a reference for various diagnostics procedures. It presents the lecture notes of a course carrying the same name within Medical Studies in English at the University of Zagreb for more than a decade.
