DEFINATION : microwave diathermy of the tissues with radiation in the shorter wireless part of the electromagnetic spectrum, e.g. with a wavelength between infra-red and short-wave diathermic radiation. there is some variation in defination, but waves of 1-100cm may conveniently be classified as microwave. WAVELENGTH : 12.25cm FREQUENCY : 2450 MHz some use is made…
DEFINATION : Iontophoresis is a treatment technique, in which an electrical current is used in physical therapy. It is applied to the skin soaked in tap water allowing ionized or charged particles to pass the normal skin barrier. The iontophoresis method is used as a non-invasive transdermal drug delivery treatment technique based on the transfer…
DEFINATION: Electrical stimulation of the muscles that generally act as the muscle pump may be combined with compression and elevation of the limb to increase venous and lymphatic return and so relieve oedema. Goal : Faradism Under Pressure is used for edema control and to improve the venous and lymphatic drainage from the edematous area,…
FARADIC CURRENT faradic type current is a short duration interrupted direct current. They have a pulse duration of 0.1 to 1 ms and a frequency of 50 to 100 Hz. The point here to note is faradic current is direct current but with a short duration interruption of 0.1 to 1 microsecond. the term faradism…
COLD THERAPY USE IN PHYSIOTHERAPY
What is Ultra-Violet Radiation therapy? ultraviolet radiation elecutromagnetic energy which is invisible to the human eyes, with wavelength between 10nm and 400nm. ultra-violet lies between visible light and x-ray in the electromagnetic spectrum and for descriptive purpose the therapeutic part of the uv spectrum may be divided into (1)UVA(long UV)400-315 nm (penetrates to dermis,responsible for…
DEFINATION OF LASER : Laser therapies are medical treatments that use focused light. Unlike most light sources, light from a laser (which stands for light amplification by stimulated emission of radiation) is tuned to specific wavelengths. This allows it to be focused into powerful beams. Laser light is so intense. According to Posten et al, properties of low…
Introduction of Ultrasound : Ultrasound Waves : Ultrasound waveform with compression and rarefaction These three factors are related, but are not constant for all types of tissue. Average figures are most commonly used to represent the passage of US in the tissues. Typical US frequencies from therapeutic equipment are 1 and 3 MHz though some…
DEFINATION: Short Wave Diathermy : Short Wave Diathermy is Also called SWD – is a Electric Machine that are useful in treatment that uses electromagnetic energy to produce deep heating in joints and soft tissues. This form of heat can be applied to deeper structures than other forms of heat treatment. It uses a high-frequency…
