Laser Therapy

What is LASER Therapy?

LASER actually stands for "Light Amplification by Stimulated Emission of Radiation." In physical therapy, we use "Cold" or "Low-Level" Laser Therapy. Instead of using high-powered lasers that heat up or cut tissue (like the ones used in surgery), this therapy uses very gentle, low-intensity light.

This special light helps relieve pain, speeds up wound healing, and helps damaged tissues rebuild themselves naturally.
 

The Different Types of Lasers

Lasers are grouped by how strong they are (from Class 1, which are harmless, to Class 4, which are very powerful). Generally, they fall into two main categories:

1. Hot (High-Power) Lasers These are the heavy-duty lasers used by surgeons. They generate a lot of heat and are used to cut tissue, stop bleeding, or destroy tumors.

2. Cold (Low-Power) Lasers This is what physical therapists use! They are called "cold" because they don't produce any heat. They work on a "Goldilocks" principle: if the light is too weak, it does nothing, but if it is just right, it perfectly stimulates the cells to heal. This method is completely painless and non-invasive. The light rays in these lasers are all the same color, travel perfectly straight, and work together in perfect harmony to heal your body.
 

Common Physical Therapy Lasers:

• Helium-Neon (He-Ne): Produces a visible red light. It doesn't travel very deep, so it is mostly used for skin wounds and surface-level pain.

• Gallium-Arsenide (Ga-As): Produces an invisible infrared light. Because it can travel much deeper into the body, it is used in short, rapid pulses to heal deep muscle and joint injuries.
   

How Exactly Does It Work?

It is basically like photosynthesis for your body! When the therapist places the laser device against your skin, non-heating light particles (photons) travel through your skin and into the damaged tissue.

Your cells absorb this light and use it to boost their energy (ATP). This extra energy jumpstarts the cell's natural repair process, dramatically speeding up healing time, flushing out inflammation, and stopping pain signals.
 

What Happens During an Appointment?

Your therapist will first clean the skin over your injury and might apply a little water or gel so the light can travel easily. They will calculate the exact "dose" of light you need based on the size of your injury and how deep it is.

Then, they will either gently touch the laser to your skin (for deep muscle pain) or hold it just above your skin (for open wounds).

What does it feel like? Honestly, you won't feel much at all! It is completely painless. You might feel a very mild, soothing warmth, but there is no vibration, burning, or discomfort.
 

The Biggest Benefits of Laser Therapy

This therapy is a favorite because it does so many wonderful things for the body:

• Quickly reduces everyday aches and pains.

• Gives cells the energy they need to repair themselves faster.

• Speeds up the healing of open cuts and wounds.

• Calms down angry, sensitive nerves after an injury.

• Stops thick, stiff scar tissue from forming.

• Actually encourages new bone and cartilage to grow!
   

What Problems Can It Fix?

Because it speeds up natural healing, laser therapy is fantastic for treating:

• General, long-lasting chronic pain

• Tennis or Golfer's elbow

• Heel pain (Plantar Fasciitis)

• Shoulder pinching and "Frozen Shoulder"

• Slipped (herniated) discs and Sciatica nerve pain

• Pelvic pain

• Knee, hip, and ankle arthritis (Osteoarthritis & Rheumatoid)

• Inflamed tendons (Tendonitis)

• Jaw pain (TMJ)

• Nerve pain from diabetes (Diabetic Neuropathy)

• Hip or shoulder swelling (Bursitis)
   

How Many Visits Will You Need?

It depends entirely on your injury. A brand-new injury might feel better after just a few sessions, while an old, stubborn pain might take longer. Usually, therapists recommend 3 to 4 short sessions (about 20 to 25 minutes each) per week for the best results.

Are There Any Side Effects or Risks?

When done by a professional, it is incredibly safe. Sometimes, the treated area might look a little pink (like a very mild sunburn) or feel slightly warm or tingly afterward, but this goes away quickly.

Important Safety Rules:

• Protect Your Eyes: You and your therapist MUST wear special protective glasses, as looking at the laser can hurt your eyes.

• When to Skip It: You should NEVER use laser therapy if you:

  • Are pregnant (to protect the baby).

  • Have cancer or a tumor in the area being treated.

  • Have epilepsy.
