Interferential Therapy / Interferential Current (IFC) I Physiotherapy: Dr Roh...Dr Rohit Bhaskar, Physio
The basic principle of Interferential Therapy (IFT) is to utilise the strong physiologicaportable iftl effects of low frequency (<250pps) electrical stimulation of nerves without the associated painful and somewhat unpleasant side effects sometimes associated with low frequency stim.
To produce low frequency effects at sufficient intensity at depth, patients can experience considerable discomfort in the superficial tissues (i.e. the skin). This is due to the impedance of the skin being inversely proportional to the frequency of the stimulation. In other words, the lower the stimulation frequency, the greater the impedance to the passage of the current & so, more discomfort is experienced as the current is ‘pushed’ into the tissues against this barrier. The skin impedance at 50Hz is approximately 3200* whilst at 4000Hz it is reduced to approximately 40*. The result of applying a higher frequency is that it will pass more easily through the skin, requiring less electrical energy input to reach the deeper tissues & giving rise to less discomfort.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

Health Education on prevention of hypertensionRadhika kulvi
Hypertension is a chronic condition of concern due to its role in the causation of coronary heart diseases. Hypertension is a worldwide epidemic and important risk factor for coronary artery disease, stroke and renal diseases. Blood pressure is the force exerted by the blood against the walls of the blood vessels and is sufficient to maintain tissue perfusion during activity and rest. Hypertension is sustained elevation of BP. In adults, HTN exists when systolic blood pressure is equal to or greater than 140mmHg or diastolic BP is equal to or greater than 90mmHg. The

3. Sound is defined as the periodic mechanical
disturbance of an elastic medium such as air.
Sound requires a medium for its transmission
and cannot cross a vacuum.
The human ear can hear up to a frequency of
20hz - 20khz
Ultrasound refers to mechanical vibrations, which
are essentially the same as sound waves but of a
higher frequency above 20khz. Such waves are
beyond human hearing and can therefore be
called ultrasonic.
Therapeutic frequencies range from 1MHz-
3MHz.
4. Therapeutic ultrasound is produced when
high frequency current is imposed on
materials with piezoelectric qualities to
cause the piezoelectric effects.
Ultrasound(US) is a deep heating modality
6. Therapeutic US is produced when high frequency
current is imposed on materials with
piezoelectric qualities to cause the piezoelectric
effect.
When electrical energy is applied on piezoelectric
crystals they produce vibration and mechanical
deformity of their molecular structure. This
phenomenon is called piezoelectric effect. This
principle is used for generation of ultrasound
waves
Piezoelectric crystals (e.g. Germanium, quartz,
barium titanate, Lead- Zirconium-Tartarate etc.)
convert mechanical energy into electrical energy.
7. The ultrasound machine consists of a
electricity source, coaxial cable, main body
(includes the knobs and buttons), user
graphic interphase, treatment
head/applicator/transducer/sound head.
8.
9. These are determined with the following in
mind:
a) Type of condition and
b) Depth and position of the lesion.
The treatment parameters include:
Mode
Intensity
Time
Frequency
10.
11.
12. US waves are not transmitted by air.
Coupling medium is used between the patients skin
and the transducer.
Couplants should also serve as lubricant to allow
treatment head move smoothly over skin.
Here are some coupling media and their transmission
rate:
Aqua sonic Gel 72.6%
Glycerol Gel 67%
Distilled Water 59%
Liquid Paraffin 19%
Petroleum Jelly 0%
Air 0%
13. Reflection & Refraction: if the US beam
encounters an interface between two media while
being transmitted it may be reflected i.e.
Deflected from its original path
Care is taken not to leave air between the
transducer head and patients skin.
If US waves are reflected there are tendencies of
damaging the piezoelectric crystals.
There may also be refraction of the longitudinal
waves at the bone interface. Which is
accompanied by a change in speed and
wavelength of the waves.
14.
15. Attenuation: this is the gradual reduction of
the intensity of the US beam after it has left
the treatment head.
Two main factors contribute to this:
Absorption
Scatter
Absorption and scatter reduces the intensity
and brings about half-life.
17. US can be used in treatment of:
Acute soft tissue injuries
Scar tissues, keloid and contractures
Chronic indurated oedema
Pain relief
Bone injuries
Chronic strains/sprains
Wound healing
Inflammation of joint capsules, tendons,
ligaments and bursa often associated with
degenerative conditions like osteoarthritis,
rheumatoid arthritis and repetitive stress injuries
18. Improves protein synthesis thus, increasing
the rate of repair of damaged tissues.
US helps to reduce pain, break unwanted
calcification of soft tissues and restore
function as well as increased extensibility of
collagen fibers increasing range of motion.
19. Physiotherapist(PT) should test the ultrasound
machine to ensure proper production of the
US before treatment
A water bath is used to reflect ultrasound
beam up to the surface of the water
The ultrasound Machine is turned on while
the treatment head blows the water and
ripples indicate production of US waves.
20. Direct contact or surface method
Water bath or Under water method
Water bag method
21.
22. Phonophoresis: is the movement of drugs
through the skin into the subcutaneous
tissues under the influence of US
The thermal and biological effects of
ultrasound increases tissue permeability and
these aid at driving the medication into the
tissues.
The type of ointment used depends on the
physiological needs of the patient e.g
salycilate. zinc. iodine. hydrocortisone etc
23. US can be used to treat both Acute and Chronic lesions.
Acute lesions: a low dose intensity of 0.25-0.5w/cm2
can be used for 2-5mins at initial stages and if
condition doesn’t improve time can be increased or an
intensity of 0.8w/cm2 for 5mins.
Chronic lesions: can be treated with a pulsed or
continuous mode. The maximum intensity of US which
should be used is that which produces mildly
perceptible warmth. Which usually occurs at 2w/cm2.
A dose of 2w/cm2 for 8mins is usually considered.
If treatment doesn’t improve even at a gradually
increased dose and time then US treatment should be
discontinued.
24. Growing epiphysis
Poor blood supply
Pregnancy
Cardiac disease
Tumors
Radiotherapy
Acute sepsis and other infections
Bony prominences
Vascular conditions
Metallic implants
Anesthetic area or area with defective nervous
sensation.
25. Burns
Damage of equipment
Unstable cavitation may occur
Overdose may lead to exacerbation of symptoms
Treatment area should be clean and dry before
applying coupling gel
Treatment time should be between 5-10mins
never treat over 15mins regardless of the
treatment area.
Ultrasound should be discontinued if there is no
improvement after a maximum of 8 sessions
26. Ultrasound intensity should be adjusted to
patients tolerance
After treatment the treatment head should be
wiped off and placed in its bracket. Then
clean the coupling medium off the patient.
the intensity level turned down to zero so the
intensity is not on when next the machine is
turned on.
