Low-intensity pulsed ultrasound (LIPUS) is a technology that can be used for therapeutic purposes. It exploits low intensity and pulsed mechanical waves in order to induce regenerative and anti-inflammatory effects on biological tissues, such as bone, cartilage, and tendon.

When do you use pulsed ultrasound?

Low-intensity pulsed ultrasound (LIPUS) is a form of ultrasound that delivered at a much lower intensity (<3 W/cm²) than traditional ultrasound energy and output in the mode of pulse wave, and it is typically used for therapeutic purpose in rehabilitation medicine.

Why use pulsed vs continuous 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 ...

What is continuous ultrasound used for?

Purpose: Low-intensity continuous ultrasound (LICUS) is an emerging high-dosimetry ultrasound-based therapy for accelerated tissue healing and the treatment of myofascial pain.

Why do we use therapeutic 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.

Does ultrasound help with inflammation?

Ultrasound (US) therapy is used to reduce pain and inflammation and to accelerate healing after soft tissue injury.

Is ultrasound effective for therapy?

Therapeutic ultrasound is one of the most widely and frequently used electrophysical agents. Despite over 60 years of clinical use, the effectiveness of ultrasound for treating people with pain, musculoskeletal injuries, and soft tissue lesions remains questionable.

What is an effect of ultrasound in the pulsed mode?

Several investigations have shown that continuous and pulsed low-intensity ultrasound therapy on damaged tissues accelerates the regenerative processes, reduces inflammation and pain, enabling recovery of function [3-8,12,13].

Is pulsed ultrasound treatment effective in knee osteoarthritis?

Treatment of pulsed ultrasound has no positive effect on knee pain, function, femoral cartilage and synovial sac thickness in knee osteoarthritis.

Which is deeper 1mhz or 3mhz?

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 is UST therapy?

Therapeutic ultrasound is one of the most commonly used and well accepted electrotherapy modality in treating various musculoskeletal conditions. Ultrasound therapy is usually used with the help of a coupling media. The coupling media, such as water, oil or gel prevents reflection of the ultrasonic wave away.

Does ultrasound break up scar tissue?

One of the many benefits of ultrasound therapy is breaking up scar tissue caused by injuries or surgery. Scar tissue can cause pain and restrict joint movement. Ultrasound helps by using high-frequency sound waves to break the fibres of the scar tissue down into smaller fragments.

What is ultrasound Slideshare?

Ultrasound imaging, also called sonography, involves exposing part of the body to high- frequency sound waves to produce pictures of the inside of the body. • Ultrasound examinations do not use ionizing radiation (as used in x-rays).

Is High Intensity Focused ultrasound Safe?

HIFU offers a very favorable safety profile. The most important risk is the risk of a skin burn. In order to minimize this risk, cooling devices and procedures are used to protect the skin during the treatment procedure.

Can ultrasound burn your skin?

Ultrasound physical therapy has a low risk of causing complications. But, exposure to low-intensity ultrasound for a long time may cause superficial burns on the skin. So, medical practitioners usually ensure that the ultrasound probe is in motion when in contact with your skin.

Does ultrasound help heal ligaments?

Background: Ruptured medial collateral ligaments are capable of healing over time, but biomechanical and biochemical properties remain inferior to normal tissue. Low-intensity ultrasound may improve healing. Hypothesis: Medial collateral ligaments treated with ultrasound will demonstrate superior healing.

What will an ultrasound show on my knee?

Muscles around the knee joint (to exclude tears, atrophy), medial, lateral collateral ligaments, quadriceps tendon, ligamentum patellae can be assessed with knee ultrasound. Additionally periphery of the menisci, thickness of the meniscus, joint effusions, Baker's cysts can be assessed reliably.

Can I use ultrasound on my knee?

Ultrasound, commonly used to image the inside of the body through soundwaves, can also be used at higher intensities to relieve pain,² promote healing, and reduce swelling. Clinicians currently use ultrasound therapy for knee pain, treating it for several minutes a few times a week in the office.

Does ultrasound heal cartilage?

Low-intensity pulsed ultrasound accelerates bone healing via upregulation of cartilage for- mation and maturation phases of endchondral bone formation. The current authors evaluated the effect of ultrasound therapy on the repair of full-thickness osteochondral defects.

How does ultrasound help healing?

As well as heating and relaxing the muscles, ultrasound therapy breaks down scar tissue and increases local blood flow. All of this combines to increase healing rates in the area, making it a suitable way to speed up slow-healing or chronic issues.

Does ultrasound accelerate healing?

Ultrasound is also thought to improve cellular function by making microscopic gas bubbles near your injury expand and contract rapidly, a process called cavitation. This expansion and contraction are thought to speed up the healing process in your injured body part.

What are the indications for ultrasound?

Indications for Ultrasound <12 Weeks Gestation

• hyperemesis gravidarum:
• diabetes mellitus;
• hypertension;
• toxaemia of pregnancy;
• liver or renal disease;
• autoimmune disease;
• cardiac disease;
• alloimmunisation;

How long should you do ultrasound therapy?

According to Rosenzweig, “Therapists use ultrasound anywhere from six to 12 sessions – it's part of the patient's therapy, so therapists might do it for five minutes, then perhaps twice a week anywhere from thee weeks to six weeks.

What does an ultrasound do for pain?

The sound waves, or ultrasound rays, penetrate within the body generating heat increasing blood flow, and relaxing muscles and connective tissues thereby reducing pain and muscle spasms. The stimulation of these tissues in this way encourages repair and can greatly reduce the healing time of certain injuries.

What does ultrasonic do for the skin?

Ultrasonic therapy uses high-level sound waves — far beyond the range audible to humans — to stimulate cells far beyond the superficial layers of skin, which jumpstarts collagen production, reduces inflammation, and promotes blood circulation (hence, the glow).
