Fundamentals of Electrotherapy and Biomedical Physics aims to provide basic concepts of electrotherapy to the students. Exercise therapy and electrotherapy are two important components of physiotherapy treatments. By this book, the aim is to provide study materials which will help the students to go into details about all the instruments they are using. Most of the universities have a subject in the first year of bachelor of physiotherapy that teaches about fundamentals of electrotherapy. But, there is no specific book for that. So, by this book, effort is to made to solve the demand of students for the basics of electrotherapy.
The first chapter gives fundamental concepts of circuit, electric charge, electric current, voltage, resistance, etc. to form strong base of further studies for their higher standard in college. Chapter 2 contains ideas about conductors, insulators, and semiconductors, including their examples and uses. Chapter 3 provides the material and detailed knowledge about the construction, mechanism, and types of switches, plugs, sockets and fuses. Chapter 4 explains from how electricity is generated to its use in our home for home appliances, including its generation, distribution, transmission and usage in detail. Chapter 5 contains sources of direct current ranging from simple primary or secondary cell to thermionic valve and choke coil. Chapter 6 will help to form the base of ultrasound and other electric modalities by clearing doubts about skin resistance, conducting medium, and different types of electrodes. Chapter 7 will guide the students how to manage if electric shock or earth shock occurs in physiotherapy department, as causes, types, prevention and treatment of electric shock, and earth shock are explained. Chapter 8 clears the concepts of magnet, magnetic field, and other properties exhibited by magnet. Chapter 9 explains in details about introduction about electromagnetic spectrum and its governing laws such as reflection, refraction, attenuation, cosine law, inverse square law which will help students to fix the placement of different electrotherapeutic instruments for best result. This will also provide base for infrared and ultraviolet rays for future standards of college. This chapter also provides uses of different types of rays used in day-to-day life. Chapter 10 explains about electromagnetic induction in detail that is must to know before understanding the transformer. Chapter 11 elaborates transformer with its types such as step-up, step-down, etc. for good understanding of voltage regulations. Chapter 12 explains the details for transistor with its types and mechanism of work. Chapter 13 provides base for understanding about capacitor, including its construction, types and uses which will help the reader learn shortwave diathermy easily for getting maximum output from machine. Chapter 14 gives detailed knowledge about pain and its regulation so that the reader will be able to understand that whatever electrotherapy modality he/she is using for pain relief that works on which level and mechanism.
The effort is also made to provide all study materials with references from different books of electrotherapy. To get recent advances of all covered topics reference websites are also mentioned at the end of the chapter.
For freshers, most of the time, they have reading materials; but, they are confused how to face this in examinations. To solve this to level best, effort is made to provide multiple choice questions (MCQs) with answers.
All the readers are requested to provide their suggestions regarding this book so that next time precaution can be taken. Feel free to contact on kakkadashish@yahoo.co.in. The author hopes to get best response from the readers.
