What is ultrasound therapy?
Ultrasound Therapy. Ultrasound therapy has been used as an electrotherapy treatment modality by therapists over the last 50 years.It involves passing high frequency sound waves into soft tissue.
How does ultrasound work?
Ultrasonic waves or sound waves of a high frequency that is not audible to the human ear are produced by means of mechanical vibration in the metal treatment head of the ultrasound machine. The treatment head is then moved over the surface of the skin in the region of the injury transmitting the energy into the tissues.
How does ultrasound affect collagen?
As the ultrasound waves pass from the treatment head into the skin they cause the vibration of the surrounding tissues, particularly those that contain collagen. This increased vibration leads to the production of heat within the tissue. In most cases, this cannot be felt by the patient themselves. This increase in temperature may cause an increase in the extensibility of structures such as ligaments, tendons, scar tissue, and fibrous joint capsules. In addition, heating may also help to reduce pain and muscle spasm and promote the healing process.
Why is ultrasound therapy important?
One of the greatest proposed benefits of ultrasound therapy is that it is thought to reduce the healing time of certain soft tissue injuries. Ultrasound is thought to accelerate the normal resolution time of the inflammatory process by attracting more mast cells to the site of injury.
Why do you put ultrasound gel on your skin?
When sound waves come into contact with air it causes a dissipation of the waves, and so a special ultrasound gel is placed on the skin to ensure maximal contact between the treatment head and the surface of the skin and to provide a medium through with the sound waves can travel. Ultrasound can also be applied underwater which is also a medium ...
Does ultrasound help with scar tissue?
Hence ultrasound may accelerate the proliferative phase of tissue healing. It is thought to improve the extensibility of mature collagen and so can have a positive effect on fibrous scar tissue which may form after an injury.
How Is Ultrasound Applied?
Ultrasound is performed with a machine that has an ultrasound transducer (sound head). A small amount of gel is applied to the particular body part; then your physical therapist slowly moves the sound head in a small circular direction on your body.
What is therapeutic ultrasound?
Therapeutic ultrasound is a treatment modality commonly used in physical therapy. It is used to provide deep heating to soft tissues in the body. These tissues include muscles, tendons, joints, and ligaments.
How Does Ultrasound Work?
Inside your physical therapist's ultrasound unit is a small crystal. When an electrical charge is applied to this crystal, it vibrates rapidly, creating piezoelectric waves. These waves are emitted from the ultra sound sound head as ultra sound waves.
Why is ultrasound used in the body?
Ultrasound is often used to provide deep heating to soft tissue structures in the body. Deep heating tendons, muscles, or ligaments increases circulation to those tissues, which is thought to help the healing process. Increasing tissue temperature with ultrasound is also used to help decrease pain.
What are the contraindications for ultrasound?
There are some instances where you should not use ultrasound at all. These contraindications to ultrasound may include: 1 Over open wounds 2 Over metastatic lesions or any active area of cancer 3 Over areas of decreased sensation 4 Over parts of the body with metal implants, like in a total knee replacement of lumbar fusion 5 Near or over a pacemaker 6 Pregnancy 7 Around the eyes, breasts, or sexual organs 8 Over fractured bones 9 Near or over an implanted electrical stimulation device 10 Over active epiphyses in children 11 Over an area of acute infection

Can a physical therapist use ultrasound?
Your physical therapist may use ultrasound to help improve your condition. If so, be sure to ask about the need for ultrasound and possible risks. Also, be sure that you are also performing an active self-care exercise program in the PT clinic and at home. If you are actively engaged in your rehabilitation, you can ensure that you have a safe and rapid recovery back to normal function.
What determines how ultrasound physical therapy is done?
The frequency and intensity of the ultrasound, the duration of the procedure, and the area of its application all determine how ultrasound physical therapy is done.
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 mechanical ultrasound?
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.

Why do we use ultrasound?
But, it's most commonly used to solve problems in muscle tissue. The heating effect of the ultrasound helps to heal muscle pain and reduces chronic inflammation. . Ultrasound also helps tissue fluids flow better — which means that more lymph passes through the tissues.
What are the two types of ultrasound?
There are two types of therapeutic ultrasound: thermal and mechanical.
What is therapeutic ultrasound?
Therapeutic ultrasound is a tool in wide use by physical therapists. If it is offered to you as part of your treatment, it should always be part of an overall treatment plan that includes exercise, stretches, or other focused activities.
What is ultrasound used for?
This is diagnostic ultrasound used to capture images of organs and other soft tissues.
Why do physical therapists use ultrasound?
Your physical therapist (PT) might use therapeutic ultrasound to provide deep heating to soft tissue to increase blood circulation to those tissues. This could, theoretically, promote healing and decrease pain.
Why do we use ultrasound?
Therapeutic ultrasound is often used for treating chronic pain and promoting tissue healing. It may be recommended if you experience any of the following conditions:
Is therapeutic ultrasound effective?
The effectiveness of therapeutic ultrasound has not been documented through research. For example, a 2014 study. Trusted Source. on 60 people with knee osteoarthritis concluded that the use of the treatment offered no additional benefit in pain improvement and functions.
Can ultrasound be used for heat?
The U.S. Food and Drug Administration has approved the use of therapeutic ultrasound by licensed professionals. It has the potential to produce harm if the heat is left in the same place too long. If, while being treated, you feel discomfort, alert your PT right away.
Can ultrasound cause microplosion?
One potential risk with therapeutic ultrasound is that the rapid pressure changes during cavitation could cause a “microplosion” and damage cellular activity. This is unlikely to occur in most uses of the treatment.
How long does it take to treat a lesion with ultrasound?
Working on the principle of 1 minutes worth of ultrasound per treatment head area, the total time taken to treat the lesion will be (1 minute) x (number of times the treatment head fits over the lesion) x (the pulse ratio) which in this instance = (1) x (1) x (5) = 5 minutes.
How to work out ultrasound dose?
The most straightforward way to work out a particular dose of ultrasound for an individual patient is to use the combined available evidence and the flowchart below is based on just that . Following the flowchart is a piece of text that explains the process in some more detail. Both the flowchart and the text can be downloaded from the DOWNLOADS page for easier printing.
How is the rate of ultrasound absorbed?
The rate at which ultrasound is absorbed in the tissues can be approximately determined by the half value depth - this is the tissue depth at which 50% of the ultrasound delivered at the surface has been absorbed. The figures used for these estimates are average values in that it absolute values will vary with the thickness of various tissues (e.g. skin, fat, muscle etc). The average 1/2 value depth of 3MHz ultrasound is taken at 2.5cm and that of 1MHz ultrasound as 4.0 cm though there are numerous debates that continue with regards the most appropriate half value depth for different frequencies.
How does the intensity of ultrasound vary?
In a similar way to the pulse ratio decision, the intensity of ultrasound required at the target tissue will vary with the tissue state. The more acute the lesion, the less strong the ultrasound needs to be in order to achieve/maintain the tissue excitement. The more chronic the tissue state, the less sensitive, and hence the greater the intensity required at the lesion in order to instigate a physiological response.
How much ultrasound energy is needed for every treatment head?
The final compilation of the treatment dose which is most likely to be effective is based on the principle that one needs to deliver 1 minutes worth of ultrasound energy (at an appropriate frequency and intensity) for every treatment head that needs to be covered.
How much surface dose is needed for ultrasound?
There IS a need to increase the surface dose to allow for loss of ultrasound at depth, and using the tables above, it is estimated that the required surface dose will need to be 0.75 W/cm2 (though of course this will depend on the size of the patient – it is not a universal formula)
Which is better, 3MHz or 1MHz ultrasound?
3MHz ultrasound is absorbed more rapidly in the tissues, and therefore is considered to be most appropriate for superficial lesions, whilst the 1MHz energy is absorbed less rapidly with progression through the tissues, and can therefore be more effective at greater depth.
