2. 2.  Electricity is an element of PT modalities most frightening and least understood. Understanding the basis principles will later aid you in establishing treatment protocols.
3. 3. • Amplitude window• Frequency window• Acute window• chronic window• Energy based window• Time based window• Interval based window

5. 5.  Introduction Definition Physical characteristics Therapeutic uses Treatment regimes Practical application Contra-indications Dangers
6. 6.  Widely used electrotherapy modality Used since the 1950s to utilise the therapeutic aspects of low frequency currents without the discomfort
7. 7.  Two medium frequency currents of slightly differing frequency are applied to the body in such a manner to produce; an amplitude modulated medium frequency current within the body. Amplitude modulation provides a beat frequency that is within the biological frequency range
8. 8. PRODUCTION OF IFT
9. 9. medium frequency A + medium frequency B = low (therapeutic) frequency C
10. 10. 1. Z=1/2Π fC ,Z = skin impedance f = frequency in Hertz (Hz) C = capacitance of skin in microfarads
11. 11. Skin impedance is of two types ohmic resistance and capacitive resistance. Capacitive resistance is developed deep in the tissues due to electrolytic potential difference generated in the cell membrane
12. 12.  2.Accomodation is delayed. 3.Current can travel at the depth of the tissue. 4.Alternating current can be used 5. Stimulus asynchronous stimulation is applied for production of interferential current so Wedensky inhibition doesn’t takes place and thereby there is no accommodation phenomenon. Stimulus asynchronous produces Gilde-Meister effect. (In low-frequency currents, stimulus synchronous is used which causes Wedensky inhibition and thus nerve or muscle gets accommodated to that current. Inability of tissue to respond during the refractory period due to stimulus synchronus current is known as Wedensky inhibition)

18. 18.  100Hz - pain relief 50-60 Hz = muscle contraction 1-50 Hz = increased circulation The higher the frequency (Hz) the more quickly the muscle will fatigue 1-4 Hz-beta endorphin 40-100Hz-enkepalin,serotonin

22. 22. Relief of pain – pain gate theory 80-140Hz (higher IFT frequencies) Stimulates Aβ fibres To inhibit impulse transmission in A∂ and C fibres Used for both acute and chronic pain Temporary pain relief
23. 23. Relief of pain – Ascending pain suppression, 2-30Hz (lower frequencies) Stimulates A∂ fibres: To inhibit C fibre transmission Via the release of encephalins and endorphins More longer lasting pain relief Only effective on chronic pain
24. 24. Reduction of oedema 0-100 Hz Stimulates autonomic nerves to produce vasodilatation Increases circulation
25. 25. Motor stimulation 0-25 Hz - twitch 25-100 Hz - muscle contraction Can be used to treat incontinence or muscle weakness secondary to trauma/ surgery (in conjunction with active exercise).
26. 26.  Acute sepsis - ↑ risk of spread of infection Tumours - ↑ risk of increased growth of activity Pregnancy – no treatment over uterus or its’ nerve supply Cardiac disease – no treatment over the heart, cervical ganglia or vagus nerve
27. 27.  Cardiac pacemakers Febrileconditions Large open wounds Menstruation - ↑ risk of bleeding or pain if treatin abdominal of lumbar region Dermatological conditions-open wound,cuts or eczema Thrombophlebitis – risk of embolus being dislodged
28. 28.  Severe ↑ or ↓ BP – avoid lower cervical region – BP control via cervical ganglia Acute inflammation, oedema, haemorrhage or haematoma when using suction cups Hypersensitivity or fear of electrical treatment Patients who are unable to understand the treatment or what is required of them
29. 29.  Aesthenic individuals/children for rib cage placements Acute trauma Near by SWD Senile and confused patients
30. 30.  Burns – high intensity currents can cause sufficient heating to cause a burn. Mains current shock – faulty equipment Electric shock – abrupt application of high intensity current – turn current up/ down slowly General malaise Nausea Vomiting Dizziness / Faintness Migraine / Headache Neurological effects

38. 38.  Russian currents are alternating currents (AC) at a frequency of 2.5 kHz that are burst modulated at a frequency of 50 Hz with a 50% duty cycle. The stimulus is applied for a 10- second “on” period followed by a 50-second “off” or rest period, with a recommended treatment time of 10 minutes per stimulation session.1 This stimulation regimen (called the “10/50/10” regimen), applied once daily over a period of weeks, has been claimed to result in force gains, but many of the claims appear to be anecdotal
39. 39.  We believe some of the popularity of Russian electrical stimulation stemmed from a talk given by Russian scientist Dr Yakov Kots13 at a conference in 1977. Kots is reported to have advocated a stimulus regimen for increasing muscle force that he claimed was able to increase the maximum voluntary contraction (MVC) of elite athletes by up to 40%. Unfortunately, the only details of Kotswork were brief conference notes, translated from Russian and not readily accessible.13
40. 40. A monophasic/unipolar current 50to 250 micro seconds 3000hz Czechoslovakia in1970
41. 41. Frequency Analysis Method The external currents with different frequencies are considered to cause different effects in tissues. Thus we assume that tissue reactions on different frequencies in different states of the body will also differ from each other. Measuring the sensory, motor and pain thresholds by stimulating the tissue with the interference current may offer a diagnostic tool in physiotherapy and rehabilitation
42. 42.  Pain control treatment Can cause muscle contractions, but that is not why it is used Decreases patient’s pain perception by decreasing the conductivity & transmission of noxious impulses from small pain fibers (effects large diameter fibers) Moderate caffeine levels (200 mg, approx 2-3 c. coffee) may decrease effectiveness of TENS
