7PREFACE
Day-to-day, we come across various physical forces, such as warming rays of the sun, light of the moon, force of gravity, movement of our body, our ability to move from one place to another, our ability to move an object from one place to another, movement and flow of cold water, movement and flow of hot water, electrical changes, magnetism and so on. Almost all these things around us form the part of nature's inexhaustible and powerful array of forces. The same physical forces, if harnessed and properly directed are of great value in promoting healing. They can relieve pain, increase circulation, speed up repair and heal the injured body part, improve body mechanics, metabolism, inhibit growth of germs, restore disturbed function, cure the diseased body, restore homeostasis, improve health and so on. This could form the basis of physical medicine. Though the evolution of Physical Medicine or Physiotherapy has happened gradually, the physical agents in some or the other form, which are used for the treatment purpose, are reasonably old, may be as old as matter itself.
Electrotherapy is an essential and basic subject for undergraduate, graduate and postgraduate physiotherapy students. There are enough and more books available on this subject by Western authors. But personally, I feel that there are very few books available on this subject by Indian authors who can understand the needs of everybody, in a better way. So a need was felt to bring out a book, which will comprehensively cover electrotherapy in detail. The purpose of this book is to provide a foundation of knowledge for the management of most of the types of patients with electrotherapeutic modalities. I have tried to write the chapters in such a way so as to suggest that I was in front of you and explaining the matter to you. Hence, you may feel as if you are reading my lecture notes. I have also 8included my memory tricks for remembering the matter, you may use them if it works for you. Although, this book is primarily written for physiotherapeutic professionals, much of the information in this book may be useful for other clinicians who are actively involved in the management of various patients.
I have received a lot of appreciation for this book and probably being the author of this book, I got the highest award for Physiotherapist in India by being named as a fellow of the Indian Association of Physiotherapists and that too at such a young age!
The book has been added as a textbook and a reference book for physiotherapy students of various Indian universities. I would like to express my gratitude to all admirers of this book and the publisher who has encouraged me to write a revised edition.
Medical and Physiotherapy knowledge is constantly changing. As new information becomes available, changes in treatment procedures, equipment and the use of these equipments in clinical situations become necessary. I have as far as possible; taken care to ensure that information given in this book is accurate and up-to-date. However, readers are strongly advised to confirm the information. A large number of suggested reading has been included at the end. This will help more interested readers to conveniently look for extra material on the subject of their interest.
I have received valuable assistance from various people in the preparation of this book, Basics of Electrotherapy. I would like to thank all of them for their suggestions and help. I am particularly thankful to my students and colleagues who inspired me and provided me with important feedback. I am grateful to my brothers, Mohanlal Khatri, Dr Jeevan Khatri and Sanjay Kumar Khatri for their constant encouragement and support in various ways. For the help in typing and correction of the manuscript, I am indebted to my wife Mrs Sejal Khatri and my clinical assistant Dr Poonam Bagi.
The publisher M/s Jaypee Brothers Medical Publishers (P) Ltd, New Delhi, India, bestowed upon this work their highly painstaking efforts in the examination of the text, its editing and printing. I hereby, thankfully acknowledge all assistance.
In this edition, I have taken immense care to put added contents as per the recent developments and students’ feedback to me. I have 9included my personal thoughts and comments and they should be taken just as the guidelines. I would appreciate your comments about this book.
