Infrared radiation therapy is drug-free and non-invasive light-based technology in physiotherapy which provides a wide range of health benefits. It is an alternative treatment for healing acute to chronic pain and different other conditions of health. It's safer than ultraviolet rays, which can cause skin damage. Types of Infra-red Rays Generators  Non-Luminous Generator Luminous Generator Infrared rays are in an electromagnetic spectrum just above visible light, with a wavelength of 770 nm to 1 mm. These rays are relatively safe in the neonatal intensive care unit, as they are used to warm infants. In recent years IR therapy applications have moved on rapidly. For example, IR therapy was developed that does not actually require an external source of power, such as materials emitting IR, and garments that can be powered by body heat alone.  Another area of interest is the possible involvement of solar IR radiation as opposites sides of the coin in photoaging or photorejuvenation,

Electrotherapy Simplified  by Basanta Kumar Nanda The aim of this book is to focus on the electrotherapy simplified. Electrotherapy is one of the important aspects among the various approaches of patient management available to a physiotherapist. Electrotherapy Simplified has tried to give comprehensive knowledge on electrotherapy and actinotherapy, starting from basic electricity and magnetism to the theoretical and clinical aspects of the different modalities applied by physiotherapists.  This book consists of 19 chapters, which include an introduction, inflammation, repair, and role of physical agents, electrical fundamentals, magnetic energy, valves, transistors, and rectifiers, electrical measurement systems and distribution of electricity, electrophysiology of nerve transmission, and muscle contraction, low-frequency currents, electrodiagnosis, medium frequency currents, low-intensity laser therapy, ultraviolet radiation, and traction.  About 250 objective question answers have b
