Arthritis affects 58 million Americans. Red light therapy offers a non-invasive, drug-free approach to managing arthritis pain.

Types of Arthritis Treated

Osteoarthritis (OA)

  • Most common form (wear and tear)
  • Affects joints, cartilage, and surrounding tissue
  • Strong evidence for RLT treatment

Rheumatoid Arthritis (RA)

  • Autoimmune condition
  • Causes chronic inflammation in joints
  • Moderate evidence for RLT treatment

How RLT Helps Arthritis

  1. Reduces joint inflammation — Decreases inflammatory markers in joint fluid
  2. Stimulates cartilage repair — Promotes chondrocyte (cartilage cell) activity
  3. Reduces pain signals — Modulates nerve conduction in joints
  4. Improves blood flow — Enhances circulation to joint tissue
  5. Decreases morning stiffness — Common complaint in RA patients

Clinical Evidence

Osteoarthritis

2019 Meta-Analysis (Lasers in Medical Science):

  • 22 RCTs analyzed
  • Significant pain reduction in knee OA
  • Improved physical function
  • Best results with 810-830nm wavelength

Rheumatoid Arthritis

2020 Study (Photomedicine and Laser Surgery):

  • 40% reduction in morning stiffness
  • Decreased pain scores
  • Improved grip strength
  • Well-tolerated with no side effects
