What is non-thermal ultrasound used for?

Nonthermal levels of ultrasound are reported to modulate membrane properties, alter cellular proliferation, and produce increases in proteins associated with inflammation and injury repair. Combined, these data suggest that nonthermal effects of therapeutic ultrasound can modify the inflammatory response.

What is the difference between ultrasound and Phonophoresis?

Ultrasound waves then help your skin absorb the medication into the tissues beneath. Phonophoresis treats inflammation and pain in your muscles, ligaments, and joints. It’s similar to iontophoresis. Iontophoresis delivers topical medications through your skin using electrical currents instead of ultrasound.

What is the difference between continuous and pulsed ultrasound?

Continuous US (CUS) generates thermal effects by stimulating the process of tissue regeneration, changing cell membrane permeability and increasing intracellular calcium, while pulsed US (PUS) mainly produces non-thermal effects to increase tissue metabolism, enhance fibrous tissue extensibility and elevate pain …

How is phonophoresis applied?

Phonophoresis is a form of treatment that is used during physical therapy. It involves the use of ultrasound combined with a medication gel. The medication is applied to the skin, and then ultrasound waves are used to help pass the medicine through the skin and into your injured body part.

What is short wave diathermy used for?

Short Wave Diathermy (SWD) is a treatment that uses electromagnetic energy to produce deep heating in joints and soft tissues. This form of heat can be applied to deeper structures than other forms of heat treatment.

What is the difference between 1 and 3 MHz ultrasound?

Therefore, 1-MHz continuous ultrasound, with a half-value depth of approximately 2.3 cm, is frequently used to treat deep tissues that are approximately 2.3 to 5 cm deep. With its smaller half-value depth, 3-MHz ultrasound is frequently used to heat tissues that are more superficial, from 0.8 to 1.6 cm deep.

What are the nonthermal effects of therapeutic ultrasound?

Abstract. Nonthermal levels of ultrasound are reported to modulate membrane properties, alter cellular proliferation, and produce increases in proteins associated with inflammation and injury repair. Combined, these data suggest that nonthermal effects of therapeutic ultrasound can modify the inflammatory response.

Can a periosteal burn result from Phonophoresis?

Due to deeper penetration, periosteal burns may result with phonophoresis if precautions are not taken. Patients receiving iontophoresis face the possibility of an electrical burn with direct current. Whereas ultrasound drives the whole molecule of medication to the tissue, iontopho- resis drives either the positive or negative ion

What’s the normal sound range for ultrasound therapy?

Ultrasound therapy. The normal human sound range is from 16Hz to something approaching 15-20,000 Hz (in children and young adults). Beyond this upper limit, the mechanical vibration is known as ULTRASOUND. The frequencies used in therapy are typically between 1.0 and 3.0 MHz (1MHz = 1 million cycles per second).

How does ultrasound increase the temperature of tissue?

Experiments performed with nonperfused tissue demonstrated that ultrasound could increase the tissue temperature at a rate of 0.86°C/min (1 W/cm2, 1 MHz).17However, the results of these experiments were difficult to interpret because they were performed in nonperfused tissue.
