Does ultrasound work on tendons?
Now, though, sound is being used to treat chronic tendon pain more easily and to make recovery faster. Patients suffering from chronic tendon pain now have a minimally invasive treatment option that uses high-frequency sound waves—or ultrasounds—to remove damaged and scarred tissue that causes the tendon pain.
Can ultrasound damage muscles?
Eccentric contraction that forcibly increases the length of muscles and generates tensile force overextends the normal sarcomeres and triggers microdamage to them, resulting in damage to the muscle cell membranes. Such damage causes local muscle shortening, and when this is severe, muscle cell necrosis may arise.

What frequency is ultrasound?
The frequency of therapeutic ultrasound can be set from 1MHz to 3MHz, depending on the structures you wish to target. At 1 MHz, the ultrasonic waves penetrate deeper into the soft-tissue; while at 3MHz the effects are limited to more superficial structures.
What is duty cycle ultrasound?
Duty cycle is the total amount of treatment time which the ultrasound is actually ON for. This is where pulsed vs. continuous ultrasound comes into play. By setting the machine to, say 50%, you’re creating parameters in which the ultrasound will be alternatingly turned on and off, with a total “on time” accounting for 50% of the total treatment time. Continuous (100% duty cycle) ultrasound is what you want if you’re seeking thermal effects. Because pulsed ultrasound interrupts the soundwave generation, the intensity output overtime is lower; resulting in non-thermal effects.
What happens when sound waves are absorbed by the soft tissue?
When the alternating compressions and rarefactions are absorbed by the soft-tissue in the body, the mechanical energy of the sound waves (vibrations) is proposed to result in increased tissue temperature, increased localized blood flow, increased tissue extensibility, and accelerated metabolism through increased cellular permeability.
When was the systematic review of ultrasound done?
Systematic Reviews on Ultrasound. A systematic review of the effectiveness of ultrasound on musculoskeletal disorders done in 1999 by Van Der Windt, et al found that the evidence “did not support the existence of clinically important or statistically significant differences in favour of ultrasound therapy”.
Is ultrasound a good modality?
As it stands, this is the way I see it…at best, ultrasound is a moderately effective modality in treating a select few conditions if the parameters are set just right. At worst, since the potential risks and side effects are minimal, it is a waste of time for both you and your patient.
How does ultrasound work?
How Ultrasound Physical Therapy Works. The ultrasound machine works by sending an electric current through crystals found in the ultrasound probe — also known as the ultrasound wand. The probe vibrates, causing waves to travel through the skin to the body underneath. The waves transfer energy to the tissues to cause the desired effects.
What is the process of creating bubbles in tissue?
In mechanical ultrasound — also known as cavitation ultrasound therapy — the waves created by the ultrasound create pressure differences in tissue fluids, which lead to the forming of bubbles. As these bubbles interact with solid objects, they burst and create shockwaves.

It can also be used to inject drugs into tissues ( phonophoresis ), or to violently vibrate the tip of an invasive probe ( lithotripsy, usually used for gall stones).
What are trigger points in muscle tissue?
Quick muscle knot orientation: So-called “muscle knots” — AKA trigger points — are small unexplained sore spots in muscle tissue associated with stiffness and soreness. No one doubts that they are there, but they are unexplained and controversial. They can be surprisingly intense, cause pain in confusing patterns, and they grow like weeds around other painful problems and injuries, but most healthcare professionals know little about them, so misdiagnosis is epidemic. For more information about how trigger points might be involved in your own medical history, see PainScience.com’s best-selling tutorial:
Is ultrasound quackery?
Ultrasound is pseudo-quackery. The disconnect between the popularity of US and the more or less total lack of informative research is troubling. A handful of good studies is a joke for a therapy that is worth literally billions of dollars in the marketplace.
Is ultrasound therapy reliable?
At worst, there is no rational basis for US at all. Although ultrasound is almost certainly useful for some patients, some of the time, it is not a reliable or evidence-based therapy, and enjoys far more credibility than it deserves.
Is ultrasound good for medicine?
Almost everyone seems to assume that ultrasound is proven — good technological medicine — but that just doesn’t seem to be the case. There’s a whole family of “stim” therapies based on the hope that biology will work better if it’s energetically stimulated: by electricity, by laser light, by far infrared radiation.

Why is ultrasound not used during the inflammatory, proliferative and repair phases?
The application of ultrasound during the inflammatory, proliferative and repair phases is not of value because it changes the normal sequence of events, but because it has the capacity to stimulate or enhance these normal events and thus increase the efficiency of the repair phases.
What is pulsed ultrasound?
Pulsed Ultrasound. Most machines offer the facility for pulsed US output, and for many clinicians, this is a preferable mode of treatment. Until recently, the pulse duration (the time during which the machine is on) was almost exclusively 2ms (2 thousandths of a second) with a variable off period.
What is ultrasound energy?
Ultrasound (US) is a form of mechanical energy (not electrical), and therefore, strictly speaking, not really electrotherapy at all, but does fall into the Electro Physical Agents grouping. Mechanical vibration at increasing frequencies is known as Sound Energy. The normal human sound range is from 16 Hz 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 (1 MHz = 1 million cycles per second).
How does ultrasound help healing?
It is suggested that the application of US to injured tissues will, amongst other things, speed the rate of hea ling & enhance the quality of the repair. The following information is intended to provide a summary of some of the essential research in this field together with some possible mechanisms through which US treatments may achieve these changes. It is not intended to be a complete explanation of these phenomena or a comprehensive review of the current literature. It may, none the less, provide some useful basic information for clinical application.
What is the US beam?
The US beam is not uniform and changes in its nature with distance from the transducer. The US beam nearest the treatment head is called the NEAR field, the INTERFERENCE field or the Frenzel zone. The behaviour of the US in this field is far from regular, with areas of significant interference. The US energy in parts of this field can be many times greater than the output set on the machine (possibly as much as 12 to 15 times greater). The size (length) of the near field can be calculated using r2/l where r= the radius of the transducer crystal and l = the US wavelength according to the frequency being used (0.5mm for 3MHz and 1.5mm for 1.0 MHz).
What is the pattern of energy absorption?
The absorption of US energy follows an exponential pattern - i.e. more energy is absorbed in the superficial tissues than in the deep tissues. In order for energy to have an effect it must be absorbed, and at some point this must be considered in relation to the US dosages applied to achieve certain effects.
How does a wand work?
Energy is transmitted through the vibration of a handheld wand containing a crystal. It almost sounds mythological, but the device works in the following way: 1 Electrical energy is applied to the crystal, causing it to vibrate 2 The vibration causes piezoelectric waves 3 These waves are emitted through the wand head as ultrasound waves 4 Ultrasound waves enter the targeted tissue during application
