Which 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).
What is the purpose of interferential current?
Interferential current therapy (ICT, or sometimes IFC) is the most common type of electrical muscle stimulation used to treat chronic pain resulting from surgery, injury or trauma. The end goal for using ICT as part of a physical therapy or rehab program is to relieve pain and help patients heal faster.
Is IFT a medium frequency current?
Pain threshold In Table 3 we have highlighted some important studies that used IFT(Medium Frequency Current) for pain relief.
Is IFT low frequency current?
The basic principle of Interferential Therapy (IFT) is to utilise the significant physiological effects of low frequency (≅<250pps) electrical stimulation of nerves without the associated painful and somewhat unpleasant side effects sometimes associated with low frequency stimulation.
What is low frequency current?
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. Low frequency. Frequency range. 30-300 kHz.
When is interferential therapy used?
Interferential therapy is used for the following symptoms:
- Acute and chronic pain e.g. lower back pain and sciatica.
- Muscle spasm.
- Swelling following ligament sprains and muscle strains.
- Incontinence.
- Muscle weakness.
When do you use IFC and TENS?
TENS delivers low-frequency current across the surface of the skin, while IFC delivers a higher frequency current that penetrates deeper into the tissue with less discomfort.
Which current is used for stimulation denervated muscles?
Biphasic rectangular direct current (DC) impulses with duration between 30–150 ms and a frequency in between 2–22 Hz may have to be applied with an amplitude higher than that of standard NMES (200 mA) to maximize the electrical charges and to exceed the chronaxie of the denervated muscles.
What 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.
What is Rd test in electrotherapy?
Therefore, stimulation should not be applied over the abdominal area during pregnancy. TRADITIONAL CLINICAL ELECTRICAL EVALUATION TESTS. 1. Reaction of Degeneration Test. The reaction of degeneration (RD) test is a useful screening procedure for assessment of problems that may involve lower motor neurons.
What is the difference between high frequency and radio frequency?
The first and most obvious way in which they differ is that they use different technologies to heat up the deep skin tissues. HIFU delivers more precise and more intense fractional ultrasound energy while RF is based on a bulk heating strategy.
Why current is used in physiotherapy?
Electrotherapy uses electric currents to stimulate nerves and muscles through the skin. Since it is a non-invasive treatment method, it is not painful. People only feel relaxed during their sessions. In some cases, they can experience vibration or little tingling in the body.
What is the current treatment in physiotherapy?
Physiotherapists use a variety of tools to manage pain, restore range of motion, and treat conditions of the musculoskeletal system. Along with methods like joint mobilisation, stretching, and targeted exercises, your physiotherapist might recommend electrotherapy as a treatment option.
What is interferential electrical stimulation?
Interferential current stimulation (IFS) is a type of electrical stimulation that uses paired electrodes of two independent circuits carrying high-frequency (4,000 Hz) and medium- frequency (150 Hz) alternating currents. The superficial electrodes are aligned on the skin around the affected area.
Why galvanic current is used for denervated muscles?
galvanic: direct current used to stimulate denervated muscles and for ion transfer (iontophoresis). high-voltage pulsed galvanic: to relieve pain and relax muscle spasm. Stimulates normally innervated muscles. iontophoresis: the use of direct current to drive water-soluble ions through the skin.
Why Faradic current is not used for denervated muscle?
Faradic currents will not stimulate denervated muscle: The nerve supply to the muscle being treated must be intact because the intensity of current needed to depolarize the muscle membrane is too great to be comfortably tolerated by the patient in the absence of the nerve.
Which electric current can be used in electrotherapy?
Electrotherapy: Current forms/types Direct current (galvanisation) and alternating current are used as forms of low-frequency current. DC therapy uses frequency-stabilised and frequency-modulated currents. In order to prevent skin damage, however, two-phase alternating currents are usually used.
What is the difference between interferential and direct nerve stimulation?
It is not capable of direct stimulation of nerve in the common context of such stimulation. Interferential therapy utilises two of these medium frequency currents, passed through the tissues simultaneously, where they are set up so that their paths cross & they literally interfere with each other.
What is interferential therapy&how does it work?
Interferential therapy utilises two of these medium frequency currents, passed through the tissues simultaneously, where they are set up so that their paths cross & they literally interfere with each other.
Does Interferential current (IFC) reduce pain?
Despite the widespread use of interferential current (IFC), information about its clinical effectiveness is limited and controversial. The pain-reducing effect of IFC, when applied alone or as part of a multimodal treatment plan to treat musculoskeletal pain, has not been determined. What new information does this study offer?
Is Interferential current alone effective for analgesia?
Interferential current alone was not significantly better than placebo and other interventions (ie, manual therapy, traction, or massage). However, heterogeneity across the included studies, along with methodological limitations identified in these studies, prevents conclusive statements regarding the analgesic efficacy of IFC.
