Joint pain is one of the leading causes of disability—affecting people of all ages. Whether it stems from arthritis or injury, finding a non-invasive, drug-free treatment option is a top priority for many.

Photobiomodulation therapy (PBMT) offers a safe alternative to painkillers and surgery. By delivering targeted laser light into joints, PBMT helps relieve pain, and improve mobility in knees, shoulders, and more.

 

Here’s What You Really Need to Know

Photobiomodulation therapy reduces joint pain by stimulating the body’s natural cellular repair processes and temporarily improving circulation in tissues surrounding the joint. It is indicated for treating pain associated with conditions like arthritis and joint stiffness.

 

Common Causes of Joint Pain

Joint pain can result from:

  • Osteoarthritis or rheumatoid arthritis
  • Injury or overuse
  • Tendonitis

Traditional treatments like NSAIDs, corticosteroid injections, or surgery come with side effects or downtime. PBMT, on the other hand, promotes pain relief without invasive intervention.

How PBMT Works for Joint Pain Relief

PBMT delivers red and near-infrared laser light into the tissues around the joint. In the case of LightForce® laser therapy, our lasers exclusively deliver near-infrared light. The light penetrates the skin and is absorbed by mitochondria in the cells, initiating a powerful cellular response.

PBMT for Joints:

  • Increases ATP to fuel cellular repair
  • Impacts the inflammatory pathways
  • Improves temporary blood flow and oxygen delivery

This can result in pain relief and improved mobility.

 

Photobiomodulation therapy (PBMT) can be applied to nearly any joint in the body. Its versatility makes it a go-to modality for supporting mobility, easing stiffness, and enhancing recovery—especially in frequently used or injury-prone areas.

 

Joint PBMT Benefits
Knees1 Support for arthritis-related pain, improved mobility
Shoulders2,3 Helps manage frozen shoulder and rotator cuff conditions
Ankles4 Aids in Achilles tendon support
Elbow5 Addresses pain associated with tennis elbow
Spine6 Helps relieve low back and neck pain
Any Joint General arthritis, stiffness, or overuse support

 

How Long Until Your Patients Feel Relief?

Many patients report improvement within 3–6 sessions, especially for mild-to-moderate joint pain. Chronic or complex conditions may require ongoing treatments for optimal outcomes.

PBMT is often used alongside physical therapy and joint-strengthening programs.

 

PBMT vs Other Joint Pain Treatments

Treatment Invasive? Requires Medication? Long-Term Benefits?
PBMT No No Possible depending on patient and condition
Cortisone injections Yes Yes Temporary
NSAIDs No Yes Symptom relief only
Joint replacement Yes Yes (pre/post) Yes, but with risk and downtime

 

Who Can Benefit Most from PBMT?

Photobiomodulation is ideal for:

  • Arthritis sufferers seeking long-term relief
  • Active adults with joint overuse or sports injuries
  • Older adults seeking drug-free alternatives
  • Younger patients looking to quickly return to activities of daily living
