940 nm tata-infrared (NIR) maimoatanga marama: He pai ake te mamae o te mamae me nga painga vascular
940 Ko te rama NIR kei roto i tetahi kohanga ahurei i roto i te photobiomodulation, he pai ake te whakamarumaru mamae me te whakanikoniko i te rere toto ka whakaritea ki nga roangaru NIR poto ake (e.g. 810 nm/850 nm). Anei he tātaritanga mo tona uara haumanu:
1. Nga Tikanga Matua & Advantages of 940nm
Vascular-Targeted Effects
- Optimal Hemoglobin Absorption:
940nm is strongly absorbed by deoxyhemoglobin (venous blood), making it superior for:- Venous insufficiency (varicose veins, chronic edema)
- Microcirculation enhancement (diabetic ulcers, Raynaud’s syndrome)
- Lymphatic drainage (reduces post-surgical swelling)
Pain Modulation
- Selective Nerve Calming:
Nga whainga C-fiber nociceptors (pain nerves) more precisely than 810nm/850nm → Better for:- Neuropathic pain (sciatica, trigeminal neuralgia)
- Post-herpetic neuralgia (shingles pain)
- Migraine prophylaxis (forehead/cervical application)
Pūkoro Pūkoro & Repair
- Te Whakatairanga Mitochondrial:
Though slightly less efficient than 810nm for ATP production, 940nm:- Penetrates 4–7cm (between 810nm and 850nm depths)
- Ka whakaiti i te ahotea oxidative in endothelial cells (vascular lining)
2. Nga Tono Haumanu
| Condition | 940nm Protocol | Taumata Whakaatu |
|---|---|---|
| Chronic Venous Insufficiency | 10–15 mins/day over affected veins | ★★★★☆ (RCT-backed) |
| Diabetic Foot Ulcers | 20 min + 660nm for wound closure | ★★★☆☆ |
| Neuropathic Pain | Pulsed 940nm (50Hz) on nerve pathways | ★★★★☆ |
| Post-Surgical Edema | Combine with 810nm for lymphatic flow | ★★★☆☆ |
3. 940nm vs. Other NIR Wavelengths
| Parameter | 810nm | 850nm | 940nm |
|---|---|---|---|
| Peak Absorption | Cytochrome c oxidase | Water/lipids | Deoxyhemoglobin |
| Pain Focus | Musculoskeletal | Deep joint/bone | Neurovascular |
| Best Combo | 660nm (kiri) | 810nm (uaua) | 635nm (arterial flow) |
Practical Note: 940nm devices often usepulsed emission (e.g., 50–100Hz) for nerve/vessel effects.
4. Treatment Protocols
- Neuropathic pain: 10 mins pulsed 940nm along nerve tracks (e.g., sciatic path)
- Circulatory issues: 15 mins continuous on limbs (veins) + 635nm for arteries
- Device types:
- Haumanu: Multi-diode laser systems (e.g., MLS Laser)
- Kainga: Hybrid LED/NIR panels with 940nm settings
5. Haumaru & Whakataunga
- Caution with:
- Active thrombosis (DVT risk) – consult MD first
- Photosensitive medications (rare reactions)
- No erythema risk (unlike UV/blue light)
Te Rarangi Raro
940nm is thewavelength of choice for:
✔Vascular disorders (venous/lymphatic stagnation)
✔Neurogenic pain (nerve-mediated chronic pain)
✔Precision therapy when 810nm/850nm are too broad-spectrum
For comprehensive care: Whakahoahoa ki635nm (arterial) + 1064nm (deepest penetration) in clinical settings.
