Carpal Tunnel Syndrome
Source: Clinical Research Consensus
Protocol for carpal tunnel syndrome applying NIR light to the carpal tunnel area, median nerve pathway, and associated flexor retinaculum. Treatment targets nerve inflammation, reduces edema within the carpal tunnel, and promotes median nerve conduction recovery.
Protocol Parameters
| Condition | Carpal Tunnel Syndrome |
| Wavelengths | 810nm, 830nm, 850nm |
| Dosage | 3-6 J per point, 3-4 points |
| Irradiance | 50-100 mW/cm² |
| Duration | 30-60 seconds per point |
| Frequency | 5x per week for 3-4 weeks |
| Body Zone | hands |
| Evidence Level | Moderate |
Mechanism of Action
NIR light reduces perineural edema and inflammation around the median nerve, improves nerve conduction velocity, and promotes Schwann cell activity for nerve repair. Anti-inflammatory effects reduce swelling within the confined carpal tunnel space.
Key Studies
- Naeser et al. (2002) - Real vs sham laser showing significant improvement
- Chang et al. (2008) - PBM improved nerve conduction studies
- Barbosa et al. (2012) - Systematic review supporting PBM for CTS
Treatment Tips
- *Apply directly over the carpal tunnel (palmar wrist crease)
- *Treat the pronator teres area for proximal compression
- *Use at night in combination with wrist splinting
- *Higher frequency (daily) initially, then taper
Contraindications
- !Severe thenar atrophy (may need surgical decompression)
- !Active wrist fracture
