Tennis elbow (lateral epicondylitis) is inflammation of the tendons on the outside of the elbow. Despite the name, it affects not just tennis players but anyone who performs repetitive gripping or wrist extension motions. The condition is painful and slow to heal — typically 6–12 months with conservative treatment. Red light therapy can significantly speed recovery.

What the Research Says

Red light therapy has strong evidence for tennis elbow:

  • Multiple RCTs show reduced pain and improved grip strength in lateral epicondylitis after 4–8 weeks of RLT.
  • The 830–850nm NIR wavelength reduces tendon inflammation and stimulates collagen repair.
  • Recovery times can be shortened by 30–50% when combined with eccentric exercises.
  • RLT is now used in many physical therapy clinics as standard tennis elbow treatment.

The Tennis Elbow Protocol

  1. Rest the affected arm. Stop the activity causing the tendonitis. RLT can't help if you keep aggravating the tendon.
  2. Treat the outer elbow for 10–15 minutes, 2x daily. Position the device 6 inches from the lateral epicondyle.
  3. After acute pain subsides (3–5 days), start eccentric exercises. Wrist extensor eccentric exercises are the gold standard for rehab.
  4. Be patient. Tendons heal slowly. Most cases need 6–8 weeks for full recovery.
  5. Gradually return to activity. Don't rush back — relapses take longer to heal.

Eccentric Exercises

Once acute pain subsides, start eccentric wrist extensor exercises:

  1. Hold a light dumbbell (1–3 lbs) in your affected hand, palm down
  2. Use your other hand to lift the weight up
  3. Slowly lower the weight with your affected hand (3–5 seconds)
  4. Repeat 10–15 times, 3 sets
  5. Do this 1–2x daily

Combine with RLT before exercises for best results.

Frequently Asked Questions

Yes — multiple RCTs show reduced pain and faster recovery from tennis elbow with RLT. Recovery shortened by 30–50%.
Most users see improvement after 2–4 weeks of consistent daily use. Full recovery takes 6–8 weeks.
