Manual of Practical Electrotherapy has been written in a systematic manner in a very simple approach for the students, professionals of physiotherapy, teachers, doctors, rehabilitation professionals, other paramedics and public in general. Recently lots of advances have taken place in the field of electrotherapy. Utmost efforts have been made to cover all the necessary aspects of electrotherapy. All chapters have been written in a very simple and lucid manner. In ancient times, two modes of treatments?Physical therapy and Chemotherapy were available to mankind, i.e. treatment by physical means and treatment by chemical means. Physical means included the use of sun, earth, air, water, electricity, etc. Chemical means included chemical agents which were therapeutically useful for clinical purposes. Electrotherapy is an ever advancing field. Recent advances have made electrotherapy very interesting, lots of new modalities have been found effective for the treatment of various ailments. Utmost efforts have been made to make the textbook uptodate. Starting from the history of electrotherapy to the recent advances, all the aspects have been covered in details. I have tried to give a fairly complete coverage of the subject describing the most common modalities known to be employed by physiotherapists. The intention is to explain how these modalities work and their effects upon the patient. In the initial chapter, I have tried to lay the foundations of the principles of electrotherapy because a thorough understanding of these principles will ultimately lead to safer and more effective clinical practice. The nature, production, effects and uses on the body tissues of each modality are explained and illustrated.
