Etius ULM

Device for electrotherapy,
ultrasound therapy, combined therapy,
laser therapy and magnetotherapy

One device – maximum possibilities

Can one device meet the needs of a physiotherapy center? Etius ULM proves so! This is the most technically advanced device in the Etius series.
Working with a wide range of ultrasound heads, applicators, probes and electrodes, Etius ULM allows to perform treatments using:

  • Low frequency magnetic field
  • Ultrasound, phonophoresis and combination therapy
  • Unipolar and bipolar currents
  • Low level laser

In addition, Etius ULM allows the simultaneous performance of two treatments on one patient, conducting combined (combination) therapy and carrying out treatments on different patients at the same time. The multitasking of the device results from the use of two independent electrotherapy channels as well as channels generating laser radiation, low frequency magnetic field or ultrasound.

Etius ULM – benefits for the customer

Wide therapy possibilities

Etius ULM allows to perform electrotherapy treatments with the electrodiagnostics function.
Moreover, the device can be used to carry out ultrasound therapy and combination therapy treatments – combining the beneficial effects of ultrasound waves and therapeutic currents
In addition, the device works with point probes and applicators for laser therapy and plate applicators for magnetotherapy, allowing the use of a wide range of physical therapy treatments. Thanks to this, the therapy using the Etius ULM device shortens the duration of rehabilitation and brings patients quick pain relief.


The versatile Etius ULM device gives the possibility to perform a wide range of treatments also for patients who for various reasons cannot visit the physiotherapy center. Its low weight and a specially designed bag make Etius ULM a convenient tool for home healthcare environmental therapy.

Therapeutic currents

The electrotherapy using Etius ULM allows the use of all standard therapeutic currents available. In addition, the range of the device capabilities has been expanded to include: unipolar sine surge currents, microcurrents and SP-TENS currents. Importantly, Etius ULM meets the requirements of the Medical Device Directive 93/42/EEC, and two independent electrotherapy channels allow conducting two treatments simultaneously.

Etius ULM – benefits for the therapist

Programs database and treatment sequences

Etius ULM has the largest in its series database of 339 built-in programs and 110 treatment sequences for diseases requiring physical therapy. The device also allows to save up to 150 programs with treatment parameters selected by the user and create a handy list of 160 favourite programs.

Comfort and modernity

The device has been equipped with easy-to-ready graphic display and a comfortable touch panel, which makes using the Etius ULM device simple and convenient. Advanced users can choose to work in manual mode, precisely adjusting all treatment parameters.

Versatility of application

The device has been equipped with modules that support 4 therapies.
The combination of electrotherapy, ultrasound therapy, laser therapy and magnetotherapy gives a wide range of possibilities to help patients in a huge number of different ailments and at different levels of their advancement. Etius ULM together with a set of applicators and a dedicated transport bag, which are also offered by ASTAR, is a very strong foundation of the offer in the field of physical therapy, with which physiotherapy specialists meet the expectations of patients.

In order to fully understand the effect of the laser biostimulation on tissues, special attention should be paid to the word “biostimulation”. It means stimulating the body with a selected factor, as a result of which its specific reactions occur.
