導入
Achilles tendonitis is a common overuse injury affecting runners, アスリート, and even individuals who stand for long periods. 痛み, 剛性, and swelling near the heel can significantly limit mobility. This leads many people to ask: Is red light therapy good for Achilles tendonitis?
赤色光療法 (RLT), フォトビオモジュレーションとも呼ばれます, has been studied in sports medicine for its role in soft tissue repair and inflammation control. Let’s explore how it may support recovery.
What Is Achilles Tendonitis?
Achilles tendonitis involves inflammation or degeneration of the Achilles tendon — the thick band of tissue connecting the calf muscles to the heel bone.
Common symptoms include:
- Pain at the back of the heel
- Morning stiffness
- Swelling or tenderness
- Discomfort during walking or running
Because tendons have limited blood supply, healing can be slow.
How Red Light Therapy May Help
Red and near-infrared wavelengths (630–850nm) penetrate deep into soft tissue. When absorbed by mitochondria, they increase ATP production, which may:
- Accelerate tendon cell repair
- Stimulate collagen synthesis
- Reduce inflammatory cytokines
- Improve local blood circulation
- Decrease pain perception
Collagen remodeling is especially important for tendon recovery.
What Research Suggests
Studies on low-level laser therapy (LLLT) for tendinopathies indicate potential benefits such as:
- Reduced pain intensity
- Improved functional movement
- Enhanced tendon healing when combined with exercise therapy
Red light therapy appears most effective when used alongside eccentric strengthening exercises and proper rehabilitation.
How to Use Red Light Therapy for Achilles Tendonitis
Typical supportive protocol:
- 10–20分間セッション
- 3–5回毎週
- Applied directly over the tendon area
- Combined with physical therapy and load management
Consistency and gradual return to activity are critical.
最終評決
Is red light therapy good for Achilles tendonitis?
Yes — it may help reduce inflammation, stimulate collagen repair, and relieve pain when used consistently as part of a structured rehab program.
