MEDIUM-FREQUENCY alternating currents (MFACs), defined as currents in the frequency range 1 to 10kHz , are used extensively in rehabilitation.
Read moreWhich of the following is the physiological effects of IFT?
As IFT acts primarily on the excitable (nerve) tissues, the strongest effects are likely to be those which are a direct result of such stimulation (i.e. pain relief and muscle stimulation ). The other effects are more likely to be secondary consequences of these.
Read moreWhat are high frequency currents?
an alternating electric current having a frequency of 10,000 or more cycles per second ; it produces no muscular contractions and does not affect the sensory nerves.
Read moreWhat are the physiological effects of high frequency?
There were also elevations in the levels of plasma serotonin, beta endorphin, GABA and DHEA together with diminished levels of cortisol and tryptophan. Concomitant with these changes were significant improvements in the symptoms of pain, insomnia, spasticity, depression, and headache .
Read moreWhat is application of low frequency?
Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz. Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave. LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications .
Read moreWhat is medium frequency current?
Medium frequency currents are the currents whose frequency falls between the range of 1000 to 10,000 Hz . They are being used therapeutically due to their advantage of greater penetration and with a higher tolerance and comfort over the low frequency current.
Read moreWhich current is used in IFT?
Interferential therapy (IFT) is a popular electrotherapeutic modality for pain management. It is characterized by the interference of 2 medium-frequency currents (ie, 1–10 kHz) , which combine to produce a new medium-frequency current whose amplitude is modulated at low frequency (ie, <1 kHz).
