IN THIS LESSON
The way the light is delivered makes a big difference:
Treatment time: How long the light is applied
Size of treatment area: Bigger areas often work better than tiny spots.
Grid Pattern vs. Static Delivery:

A Simple Explanation
Imagine you're painting a room - you have two different approaches. You could either hold the paint brush in one spot until it's completely saturated, or you could paint in a grid pattern, moving back and forth to cover the whole wall evenly. This is exactly what happens with laser therapy delivery methods.
Static (Point) Delivery - The "Spot Treatment" Method
What it is: The laser handpiece is held in one specific spot for the entire treatment time.
How it works:
The therapist places the laser probe on your skin and keeps it there without moving
All the laser energy gets delivered to that exact same small area
It's like focusing all your attention on painting one tiny square of wall really thoroughly
When it's used:
For treating very specific trigger points or small injuries
When using pulsed (blinking) laser modes
For pinpoint accuracy on a particular problem area
Grid Pattern (Scanning) Delivery - The "Painting" Method
What it is: The laser handpiece moves continuously in a back-and-forth, up-and-down pattern like painting a grid on your skin.
How it works:
The therapist moves the laser probe steadily across the treatment area
The laser "paints" energy across a much larger surface area
It's like painting an entire wall section with smooth, even strokes
The movement pattern:
Back and forth motions (horizontal sweeps)
Up and down motions (vertical sweeps)
Covers the entire treatment area evenly
Using Higher Power with Grid Patterns - The Key Advantage
Here's where it gets interesting. When doctors use higher power lasers (called Class IV or high-intensity lasers), they almost always use the grid/scanning method instead of holding it still. Here's why:
Safety Benefits
Higher power + movement = safer treatment:
Moving the laser prevents any one spot from getting too hot
Reduces risk of burning or thermal damage
Distributes the intense energy safely across a larger area
Think of it like this: If you hold a magnifying glass in one spot in the sun, it can start a fire. But if you keep moving it around, it just warms the area gently.
Faster Treatment Times
Higher power means shorter sessions:
More energy delivered per second means less time needed overall
A treatment that might take 20 minutes with low power can be done in 2-5 minutes with high power
Patients spend less time in the clinic
Better Penetration to Deep Tissues
Higher power reaches deeper:
More photons can penetrate through skin, fat, and muscle to reach deeper problem areas
Surface tissues absorb some energy, but enough power remains to treat deep injuries
Like using a brighter flashlight to see through fog
Enhanced Pain Relief Effects
Higher intensity creates special nerve effects:
Powers above 270 mW/cm² can actually change how pain nerves work
Creates immediate pain relief by temporarily slowing down pain signals
This "neural blockade" effect happens within 10-20 minutes and can last for hours
