Myofascial Acoustic Compression Therapy

A sound approach to treating acute and chronic musculoskeletal pain. Myofascial Acoustic Compression Therapy (MyACT) is widely used in the treatment of acute and chronic pain in muscles, tendons and joints. MyACT uses acoustic waves to target tissues at varying depths by compressing and manipulating the tissue, resulting in a focused, precise, deep tissue massage. The results of the mechanical stimuli delivered by MyACT can lead to improved circulation and pain relief – key components in the healing process.
Acoustic pressure waves are characterized by a pressure surge with an extremely short rise time, which is then followed by an exponential drop in pressure and a brief phase of negative pressure. The pressure waves used in MyACT applications focus or develop in the target tissue at the point where the pain originates. The primary means by which extracorporeal pressure waves affect living tissue is based on the transformation of mechanical stimuli into biochemical or biomolecular signals, also known as mechanotransduction.

The MyAct Story

Many types of focused soundwaves have been used in the eld of medicine with great success for more than 20 years. Based on a high level of evidence, Richard Wolf GmbH – a manufacturer of lithotripsy (ESWL) and orthopaedic (ESWT) devices – has speci cally designed piezo therapy sources to generate low energy/low pressure applications for the treatment of myofascial and musculoskeletal pain.

Physical Principles

Acoustic pressure waves are me- chanical waves that result from the back-and-forth vibration
of the particles of the medium through which the sound wave is moving. A MyACT single pres- sure wave is characterized by
an acoustic pulse with a spatial expansion and a very short rise time of only a few nanoseconds. After a few microseconds, the rise is followed by a brief period of negative pressure, after which pressure returns to normal again.

Focused Therapy Source

The PiezoWave2 MyACT system offers a choice of two piezo therapy sources: the Focused Therapy Source for pinpointed, focused treatment and the Linear Therapy Source for the treatment of larger areas. Both can used for the localization and treatment of pain points.
The focal zone is the area where the pressure waves steepen to create a maximum mechanical pressure on the tissue in the area. The area is de ned in such a way that pressure waves are generated precisely in the target tissue with the requisite amount of energy, resulting in only minimal trauma to surrounding tissue.
The focal zone of a linear focused piezo source (FBL 10×5 G2blue, intensity 10) has an area of 46 mm x 20 mm x 4 mm. The “direct focusing” technology of the MyACT system means that the size of the focal area barely changes, even when the intensity settings are adjusted.
The penetration depth of the focal zone is pre-selected using gel pads of different thicknesses. A special feature of linear focused pressure waves is that users can also select a “0” gel pad. Half of the focal zone remains within the gel pad, ensuring that the peak pressure in the middle of the focus forms precisely at the skin’s surface.

Linear Therapy Source

Richard Wolf GmbH and ELvation have developed a new and unique technology: a linear, focused pressure wave. The aim was to create a more uniform and more effective focal area compared to the single pinpoint focus generated by conventional pressure wave sources. Gel pads are used to adjust the penetration depth to a depth of between 0 and 20 mm, ensuring that the acoustic eld is optimally adjusted to MyACT applications.

The piezo-electric principle for Myact

The piezo-electric principle of MyACT
Piezo ceramic crystals are arranged in a mosaic pattern on a concave transducer. A high-voltage current brie y excites the piezo crystals, causing them to expand simultaneously a few micrometers along their axis to create a pressure wave. The piezo elements are aligned precisely to the therapy focus. The precise, focused and nonlinear dissemination of the pulse results in steepening at the point of focus, creating a high pressure. The piezo MyACT system does not require an additional re ector. This accounts for the compactness of the therapy source and the precise, well-de ned focal zone. Treatment is quiet and virtually pain-free, and the technology allows the intensity levels to be freely adjusted with al- most no impact on focal size. Piezo technology is extraordinarily durable.

Mechanism of action

Years of research have shown that mechanical forces including tension and compression greatly influence various cellular functions such as gene expression, cell proliferation and differentiation and the secretion of matrix proteins.1,2,3

Cells use mechanotransduction mechanisms to convert mechanical signals into a cascade of cellular and molecularevents.1,2,3

Tenocytes in tendons, broblasts in ligaments and skin, osteocytes in bone, chondrocytes in articular cartilage, andendothelial cells in blood vessels are mechano-sensitive and respond to mechanical forces.1,2,3

Acoustic Compression Therapy’s impact with its pinpointed delivery of mechanical stimuli can generate biochemicalevents that lead to improved circulation and pain relief – key components in the healing process.1,2,3
