Protocol Recommendations
Dosing parameters for Class IV laser therapy are guided by published photobiomodulation research and are individualized based on the condition, tissue depth, patient size, and skin type. The following provides a general clinical framework drawn from the evidence base.
Key Dosing Parameters
WAVELENGTHS
500–1270 nm
Near-infrared preferred for deep tissue
ENERGY DENSITY
3–60 J/cm² AT THE TARGET
Therapeutic window per Arndt-Schulz Law
SESSION INTERVALS
2–3x/week
3-6 Sessions Acute
6-10 Sessions Chronic
SESSION DURATIONS
Average 2-5 minutes per area
2-4 treatment areas per session
The therapeutic window AT THE TARGET— the range in which photons produce beneficial biological effects — falls between approximately 3 and 50 J/cm² for most conditions. Below this threshold, insufficient photonic energy reaches the target tissue. Above 80–100 J/cm², an inhibitory effect may occur.
Pre-Programmed Protocols
VLaser systems include pre-programmed, condition-specific protocols that automatically calculate power, energy density, and session duration based on clinical selection. This feature simplifies delivery and ensures consistency, particularly for less experienced operators.
