Tendinopathy (General Protocol)
Source: WALT Guidelines 2010
This protocol applies to various tendinopathies including Achilles tendinopathy, lateral epicondylitis (tennis elbow), rotator cuff tendinopathy, and patellar tendinopathy. NIR light is applied directly over the affected tendon and its insertion points.
Protocol Parameters
| Condition | Tendinopathy / Tendinitis |
| Wavelengths | 810nm, 830nm, 850nm |
| Dosage | 4-8 J per point |
| Irradiance | 50-100 mW/cm² |
| Duration | 30-60 seconds per point |
| Frequency | 3x per week for 4-8 weeks |
| Body Zone | joints |
| Evidence Level | Strong |
Mechanism of Action
PBM increases fibroblast proliferation and collagen synthesis in damaged tendon tissue. It reduces inflammatory markers, stimulates tenocyte activity, and promotes organized collagen fiber alignment during healing. The result is structural tendon repair alongside pain relief.
Key Studies
- Tumilty et al. (2010) - Systematic review confirming efficacy for Achilles tendinopathy
- Bjordal et al. (2008) - Meta-analysis showing pain reduction in lateral epicondylitis
- Stergioulas (2007) - RCT showing accelerated Achilles tendon healing
Treatment Tips
- *Apply directly over the tendon, not just the pain area
- *Include the musculotendinous junction and bone insertion
- *Eccentric loading exercises synergize with PBM
- *Chronic tendinopathy may require longer treatment courses (8+ weeks)
Contraindications
- !Complete tendon rupture (requires surgical evaluation)
- !Active infection at the site
