Low and medium Frequency Electrotherapy - Implox

Foreword
This book on ´Low- and Medium-Frequency electrotherapy´ has been written with the aim of providing a fast and
effective means of familiarizing the user with the therapeutic possibilities of Enraf-Nonius electrotherapy equipment. A
major consideration has been that of achieving a balance between the technical background and the practical
applications.
Chapter 1 explains the concepts of Constant current (CC) and Constant Voltage (CV), and relates them to the
practical value of electrotherapy equipment as used in physiotherapy.
Chapter 2 discusses a number of theories explaining the mechanism underlying the pain reducing effect, and the
consequences with respect to phase duration, frequencies and amplitude for various types of current.
Chapter 3 provides practical information on the use of various types of low- and medium-frequency current with the
principal aims of reducing pain and restoring the balance of the sympathetic nervous system.
Diagnostic and therapeutic applications with reference to the neuromuscular system are dealt with in Chapters 4 to 6.
Chapter 4 is concerned with the application of intermittent direct current in muscle stimulation, and Chapter 5 deals
with the use of alternating currents for muscle strengthening.
Muscle stretching by means of electric currents is described in chapter 6.
The specific applications of electrical currents in iontophoresis and wound healing are dealt with in Chapter 7 and
Chapter 8 respectively. General indications and contra-indications are given in Chapter 9. Finally, chapter 10
provides examples of treatment which summarize the material in the preceding chapters.
As far as possible, this book uses the terminology* agreed upon in the book “ electrotherapeutic Terminology in
Physical therapy” , section on Clinical electrophysiology, American Physical Therapy Association, March 1990.
The authors hope that this book will be of value to the user, and will contribute to optimum use of the equipment.
