Über dieses Buch

Dynamic Modeling of Musculoskeletal Motion introduces biomechanists to modern methods of modeling and analyzing dynamic biomechanical systems in three dimensions. Using vector kinematics, the reader is taught a systematic method which significantly reduces the complexity of working with multiple, moving limb segments in three dimensions. Operations which usually require the application of differential calculus are replaced by simple algebraic formulae. To derive dynamical equations of motion, a practical introduction to Kane's Method is given.

Kane's Method builds upon the foundation of vector kinematics and represents one of the most exciting theoretical developments of the modern era. Together, these techniques enable biomechanists to decipher and model living systems with great realism, efficiency and accuracy. Interwoven with the theoretical presentation are chapters and examples which highlight the subtle differences between inanimate linkages and the biomechanical systems we seek to understand.

Introduction

Frontmatter
Chapter 1. Overview of Dynamic Musculoskeletal Modeling
Abstract
It is now the new millenium, and 3-D is where it’s at! The past few decades have seen an endless parade of analyses and modeling efforts confined to a two dimensional plane. In the past, limitations in computational power required such models to be simplified as far as one dared. Small and simple was good in many ways. Results could be easily interpreted, and generalities of the system were easily illuminated by elegant models, analyses, and interpretations. However, times have changed ! With the advent of the inexpensive and powerful desktop computer, the new focus is upon creating models that are ever more realistic and accurate in terms of their predictive power.

Chapter 2. An Introduction to Modeling Muscle and Tendon
Abstract
To apply mathematically predictable driving forces to the segments of the body using lumped-parameter models of the muscles and tendons.

Defining Skeletal Kinematics

Chapter 3. Rigid Bodies and Reference Frames
Abstract
The ability to simultaneously work in multiple reference frames greatly simplifies kinematic and dynamic analyses in three dimensions. In this chapter, the reader is introduced to direction cosines, which provide the key to analyzing models with multiple degrees of freedom.

Chapter 4. Vector Based Kinematics
Abstract
To find the positions and velocities of every point at which a force acts, the angular velocities of every body on which a torque acts, and the accelerations of every mass center.
Gary Tad Yamaguchi
Chapter 5. Models of the Skeletal System
Abstract
To define inertial properties of the body segments and ways in which they are joined together to form kinematic linkage models of the musculoskeletal system.

Chapter 6. Chapter 6 Dynamic Equations of Motion
Abstract
To introduce the reader to Kane’s Method as a means of deriving the dynamic equations of motion for a musculoskeletal system.

Chapter 7. Control
Abstract
To introduce the reader to inverse and forward dynamic methods of determining the forces and activation levels of the muscles and tendons needed to produce a particular movement.
