What is ultrasound?

Ultrasounds are sound waves with a frequency of 20 kHz – 1 GHz. This frequency is too high to be heard by the human ear. A human being is able to hear sounds in the frequency range 16 – 20,000 Hz. However, higher frequency sound waves are audible for certain types of animals, such as bats, dolphins or dogs. Ultrasound therapy uses mainly sound waves with a frequency of 1 MHz and 3 MHz.

The positive effects of using ultrasound in therapy are appreciated by specialists in physical therapy around the world. Ultrasounds affect tissues mechanically (through the so-called “internal tissue massage”), thermally, biologically and chemically. The influence of ultrasounds on the body makes ultrasound therapy an excellent method of physical therapy with local and systemic effects. Ultrasound therapy treatments are particularly valued for positive therapeutic effects in the form of analgesic and regenerative effects.

Ultrasounds relax muscles and make tissues containing collagen more elastic (scars, aponeurosis, tendons, ligaments and joint capsules).
They also accelerate wound healing and treatment of inflammation. They are irreplaceable in sports physical therapy, supporting tissue regeneration after overloads and injuries and giving relief in the case of contractures and fibrosis of muscle tissue. Ultrasound therapy is a painless treatment that lasts about 15 minutes.

PhysioGo 200A – benefits for the patient

Maximum efficiency

PhysioGo 200A was created based on the experience of physical therapists and the needs of patients seeking non-invasive, effective therapeutic treatments. The device works with ultrasound heads GS-4 (4-cm2 area) and GS-1 (1-cm2 area) generating ultrasound waves of 1 MHz and 3.5 MHz. This allows the treatment of shallowly located tissues and tendons (using the frequency of 3.5 MHz) and deeply located diseases (frequency of 1 MHz). In addition, PhysioGo 200A can emit waves by impulse (micro massage) or continuously, creating a beneficial thermal effect. Moreover, the therapist has the option of performing phonophoresis treatment – using a coupling gel with the active substance in it, which makes the treatment more effective.

Mobility

PhysioGo 200A is a lightweight device that can be successfully used in home healtcare environmental therapy. A special ASTAR PRO bag has been designed to safely transport the device and its equipment.
 
In addition, a PhysioGo 201A version has been also designed, which is equipped with a battery enabling up to 4 hours of operation without an additional energy source.

Safe therapy

PhysioGo 200A allows to conduct therapy in manual and program mode. Regardless of the mode selected, the device monitors the emitted power during the procedure and controls the contact quality of the head’s forehead to the patient’s body. PhysioGo 200A complies with the requirements of the Medical Device Directive. The device is therefore not only an effective, but also a safe tool for conducting ultrasound therapy.

Self-test

Self-test procedure implemented in PhysioGo 200A – enables current monitoring of the device’s functional status each time it is switched on. After its completion, information about connected and ready to work accessories appears on the screen of the unit – in this case, these are ultrasound heads.

Benefits for the physiotherapist

Modern design – work ergonomics

The devices from the PhysioGo family have a 7-inch colour display with a touch panel, which significantly increases the comfort of its operation. The device is elegant and relatively small despite the use of advanced technical solutions. During therapy, the device monitors the contact quality of the head to the patient’s body.

When there is no contact, the treatment timer is interrupted. Only the effective time of unltrasound therapy is counted. In addition, PhysioGo 200A is adapted to perform combination therapy. It is a combination of simultaneous electrotherapy and ultrasound therapy.
 
For this purpose, PhysioGo 200A was designed in such a way that the device allows for connection of any ASTAR electrotherapy unit.

Treatment encyclopedia

PhysioGo 200A software have a rich treatment encyclopedia, which visually and descriptively presents the methodology of treatments for individual disease entities. The simplified device operation, as many as 58 predefined treatment programs and 50 user-defined programs make PhysioGo 200A an optimal tool for physiotherapists.
 
The user can also create a list of favorite programs from the most frequently used built-in programs and give their own names to the user’s saved program list.
