LONG WAVE DIATHERMY

LONG WAVE DIATHERMY USED IN PHYSIOTHERAPY

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…

MICRO-WAVE DIATHERMY USE IN PHYSIOTHERAPY

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…
