What is ultrasound and electrotherapy?
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.
Electrotherapy is a field of physical therapy involving the treatment of diseases of the neuromuscular system using currents with various waveforms, frequencies and intensities, as well as modulated in both amplitude and frequencies. It is used both in medicine and rehabilitation of patients, as well as complementing other forms of physical therapy. The aim of the treatments is to treat pain, increase tissue blood flow and stimulate them to accelerate regeneration. Electrotherapy also supports the absorption of swelling and exudates in the joints resulting from injuries and overloads. The range of possibilities offered by electrotherapy allows to achieve a wide range of therapeutic effects.
PhysioGo 300A – benefits for the patient
A wide range of treatments
Both in the field of ultrasound therapy and in the case of electrotherapy treatments, PhysioGo 300A offers a wide range of therapeutic options. The device allows electrotherapy procedures to be carried out using uni and bipolar currents such as: microcurrents, Kotz currents, TENS currents, currents dedicated to spastic paralysis therapy, diadynamic currents, impulse currents (rectangular pulses, triangular pulses, Trabert current), tonolysis, galvanic currents and others.
Moreover, PhysioGo 300A unit in the field of ultrasound therapy generates ultrasound waves with a frequency of 1 MHz, which allow the treatment of deeply located lesions, and 3.5 MHz allowing the treatment of diseases located shallow below the surface of the skin. The therapist using an ointment in the form of a gel with the active substance during ultrasound therapy has the option of performing phonophoresis.
Another advantage of the device is the ability to perform combination therapy in a special mode. It is a combination of therapeutic effect of electrotherapy and ultrasound. During the combination therapy, both therapies work on the patient’s body simultaneously. This method is very popular among therapists worldwide.
Safe physical therapy
The self-test procedure, which has been implemented in PhysioGo 300A – enables current monitoring of the device’s functional status each time it is turned on. In the case of ultrasound therapy, the device constantly monitors the contact quality of the ultrasound head with the patient’s body during the procedure. The user can be sure of reliable and effective dosing of the ultrasound waves on the area being treated. PhysioGo 300A also gives the opportunity to check the consumption degree of the electrodes used in electrotherapy treatments. Two independent electrotherapy treatment channels make the device to be recognized as two separate devices. In order to provide patients with maximum safety during therapy, in this case galvanic separation was used between the circuits, and thus between patients.
Electrodiagnostics
PhysioGo 300A also gives the possibility to conduct semi-automatic electrodiagnostics of the neuromuscular system – I/t curve. This is the starting point to begin targeted electrostimulation to improve the fitness of the muscle undergoing therapy. After completing the procedure the device will automatically display the rheobase and chronaxia values. However, the value of the accommodation factor together with the value of the accommodation quotient will be automatically presented in a graphic form to the therapist on a legible 7” display together with a comment and visual assessment presented on a specially created scale.

Built-in treatment programs
The device user can choose to work in manual or program mode. The manual mode gives the opportunity to determine the treatment parameters independently, and its use is recommended for advanced users. PhysioGo 300A is equipped with a database of 204 built-in treatment programs combined with an encyclopedia describing and illustrating the methodology of performing treatment procedures. Additionally, the user can create a handy list of favorite treatments based on available built-in programs. The modern approach to electrotherapy treatments has been emphasized by 38 built-in treatment sequences. It is a combination of several types of current in one treatment procedure. PhysioGo 300A memory allows to save 150 own treatment programs and 10 user-defined sequences. In contrast, three independent channels give the opportunity to perform electrotherapy and ultrasound treatments to one or several patients simultaneously, which significantly reduces the duration of therapy.
Mobility
PhysioGo 300A allows to perform advanced physical treatment procedures outside the therapy centers. The device owes its mobility to small dimensions and a specially designed bag that allows safe transport for the unit along with its equipment. In addition, especially for physiotherapists conducting treatments in home healthcare environment, the ASTAR has created the PhysioGo 301A version equipped with a battery. It allows to work with the device up to 4 hours even when it is not possible to connect it to a power source.
Physiogo 300A Electrotherapy and Ultrasound Combination
The PhysioGo 300A device is a modern device for carrying out physical therapy treatments equipped with up to three therapeutic channels and a wide base of built-in treatment programs.PhysioGo 300A enables the treatment of patients suffering, among others, from musculoskeletal, nervous and soft tissue injuries.
