Interferential therapy
Interferential therapy Table of Contents Introduction Interferential therapy is a form of electrical treatment in which two medium-frequency currents produce low-frequency effects. which stimulate motor and sensory nerves, and encounter a much lower skin-impedance. Process of IFT Impedance is inversely proportional to frequency. while the application formula is Z = impedance in ohms f = […]

Laser
Laser Table of Contents A laser is a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of the radiation. The emission generally covers extremely limited ranges of visible, infrared, or ultraviolet wavelengths. Many different types of laser have been developed, with […]
