Thanks to the wide spectrum of possible therapeutic results, the high power and biostimulating laser therapy can be used to treat disorders in plenty of the medical areas, including:
- sports medicine,
- orthopedics,
- rheumatology,
- neurology,
- dermatology,
- ENT,
- dentistry.
Comparison of parameters between devices dedicated for low level and high power laser therapy on the basis of PhysioGo.Lite Laser and Polaris HPS units:

up to 10 W |
Treatment timer: | 100 min | do 100 min |
Power supply: | 100-24 V, 50/60 Hz | 230 V, 50 – 60 Hz, 130 W 150 VA |
Dimensions: | 30 x 23 x 11 cm | 36,1 x 30,4 x 15,1 cm |
Weight: | 3 kg | 6 kg |
Conclusions:
- High power laser can significantly accelerate the regeneration processes, and therefore the treatment time is shorter.
- High power laser penetrates much deeper into the tissues thanks to an additional modification of the impulse mode (superpulse).
- High power laser uses two wavelengths during the treatment, which allows to obtain deep tissue biostimulation effects as well as to achieve thermal effect.
