Preface

In recent years, many changes have taken place in the field of rehabilitation of people who need prostheses and orthoses. Advancement of technology, significant progress in computer components and robotics, and the development of new materials have enabled many people in need to return to useful and practical life. Subjects who have lost their limbs or parts of their limbs can now continue to work and perform activities of daily living.

 In line with these changes, the expectations of prosthetic and orthodontic therapists have also changed dramatically. Therapists in this field are currently trained in graduate school and are expected to research, develop, implement, or monitor the application of complex interventions. This book provides information for effective clinical decision-making for those working with people who need prosthetics and orthoses. It is also designed to assist prosthetists and orthotists to acquire the knowledge and skills necessary for effective membership in the physical therapy team.

The book is divided into two parts. The first part covers the field of prosthetics and the second part covers the field of orthotics. Each part discusses construction methods, applications, and effects of prosthetic and orthotic devices.

This book is a resource for all physicians to use to increase their ability to provide the most up-to-date care for all people in need of prostheses or orthoses.
