MODUS VET. ESWT
FOCUSED SHOCKWAVE THERAPY
It's a non-invasive procedure for the teratment of musculoscetal system diseases of horses and small animals.
Shock wave therapy is applied to horses and small animals as applied to humans.
Shock waves show antibacterial and anti-inflammatory effects in the body. It also improves vascular, bone and connective tissue.
Modus VET. Shock Wave Therapy is used to eliminate disorders in horses such as joints, tendinopathy, throat muscles, ligament injuries and deep heel pains.

Effectiveness Of Shock Wave Therapy
“As shock waves pass through different tissues, some of their energy is transmitted to the tissue and some is reflected. Micro-level changes are seen according to the physical properties of the tissue.” (Sems, Dimeff & Ianotti JP., 2006).
With shock wave therapy, the therapeutic result is easily achieved by transmitting more energy to the tissue.

FOCUSED ESWT CHARACTERISTICS
Extracorporeal Shock Wave Therapy (ESWT) is a non-invasive method and is widely used in urology as well as in various musculoskeletal diseases. There are 3 mechanisms for generating shock waves: electrohydraulic, electromagnetic, and piezoelectric.
In electrohydraulic devices, shock waves are formed as a result of the discharge of the electrode in a liquid medium due to the high voltage applied to its ends. This shock wave is focused with the help of a reflector. [1]
The working principle of electromagnetic shock wave devices is based on the induction of a magnetic field, and the shock wave is focused using acoustic lenses.
In piezoelectric ESWT devices, a large number of piezo crystals are placed inside a sphere and a rapid electrical discharge is provided. As the crystals contract and expand, a pressure is created in the water and a shock wave is produced. Focusing is determined by the geometric arrangement of the crystals inside the sphere.

ESWT DEVICE COMPARISON
Waveform Specifications
Electrohydraulic devices produce shock waves with shorter rise times than piezoelectric and electromagnetic devices. The rise times of electrohydraulic devices have been measured as approximately 35 ns, while the rise time for the Modus Focused ESWT device is 31 ns. This allows the energy to be transferred to the targeted area more quickly and the signal is less distorted while reaching the target. Since the rise time in piezoelectric and electromagnetic devices is longer, oscillations and distortions are observed more in the waves produced by these devices.For these reasons, the short rise time in electrohydraulic devices provides effective treatment to the desired area in shock wave therapy application. [3]

Penetration Depth
The penetration depth of the piezoelectric shock wave is usually up to 5 cm and is the device that reaches the lowest treatment depth. The penetration depth of electromagnetic shock waves is around 6 cm, providing a more effective treatment depth than piezoelectric devices [4]. While the penetration depth is higher in electrohydraulic shock wave devices, the maximum penetration depth in the Modus Focused ESWT device is up to 8.45 cm. This situation creates an advantage for both near-surface and deep treatments.

Treatment Zone
Piezoelectric devices have the smallest focal volume, which can make it difficult to precisely target the correct area. Although electromagnetic type devices affect a larger treatment zone than piezoelectric type devices, they do not have as large a treatment volume as electrohydraulic devices. The devices that reach the highest area in the -6 dB focal region are electrohydraulic devices. The high energy and strong focusing feature of electrohydraulic technology makes it possible to apply treatment to larger areas [5]. Since it has a large focal volume, it has been observed that it shortens the treatment time by providing more energy transfer to the treated area for a given energy flow density (mj/mm2).
