INTRODUCTION Longwave diathermy operates at a frequency range of 0.3-1MHz. The high frequency current produces heat deep into the tissues, which lasts for around 30 minutes. Longwave diathermy involves generation of oscillating electromagnetic fields (EMF) that are comprised of both electrical and magnetic fields. Variations in the strength of these fields are dependent upon several…
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…
Definition LASER Therapy is a non-invasive treatment modality increasingly used in physiotherapy to promote healing, reduce pain, and accelerate tissue repair. By utilizing specific wavelengths of light, LASER therapy penetrates deep into tissues, stimulating cellular activity and enhancing the body’s natural healing processes. Commonly applied in the treatment of musculoskeletal injuries, arthritis, and soft tissue…
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…
