Pain therapy 

Technology

• HILT provides deep, non-invasive pain relief and tissue regeneration without medication.

  High-Intensity Laser Therapy (HILT) is an advanced medical laser treatment that uses high-power laser radiation to deliver therapeutic energy deep into tissues for pain relief, anti-inflammatory action, and tissue regeneration. Unlike low-level laser therapy (LLLT), which is limited to superficial tissues, HILT penetrates deeply and activates biological mechanisms at both the cellular and systemic levels.

  HILT technology delivers controlled, high-intensity laser energy to deep tissue layers, activating biological repair mechanisms while providing fast and lasting pain relief. It combines high power, precision wavelengths, and innovative applicators to treat a wide range of musculoskeletal and neuropathic conditions—without incisions, medications, or downtime.

  Clinical versatility	Limited to superficial tissues	Broad applications in rehab and ortho	More adaptable for deep therapy	Highly adaptable (spine, joints, discs, soft tissue)
  Typical recovery impact	Mild improvement	Faster recovery vs. LLLT	Faster, safer recovery	Accelerated healing and long-term pain relief

• The effectiveness of a dual-wavelength laser system combining a 1.55 µm fiber laser and a 0.98 µm diode laser—particularly when paired with specialized applicators—is clinically significant for non-invasive cartilage regeneration and pain therapy. This combination allows for deep, selective energy delivery across multiple tissue layers and supports both biological regeneration and pain modulation.

• HILT with a cooled applicator offers superior treatment flexibility, comfort, and energy control compared to conventional HILT, enabling more effective therapy delivery in sensitive anatomical areas and in patients with low thermal tolerance.
