Therapeutic Efficacy of Different Wavelengths of Low-Level Laser Therapy in the Treatment of Cervicogenic Headache

Low-level laser therapy using the Omega XP Model with wavelengths of 675nm (30mW), 820nm (200mW), or 46-cluster LED probe (mixed wavelengths: 660nm, 950nm, 870nm, 880nm, 940nm, 820nm), applied three times weekly for 30 minutes over 6 weeks to target cervical lymphatic chain, musculature, and trigger points for pain relief in cervicogenic headache.

Warm-up: Active cervical ROM (5-10 reps, pain-free range). Stretching: Upper trapezius, levator scapulae, SCM; hold 15-30 sec, 3-5 reps, NRS ≤ 3/10. Therapeutic exercises: cervical deep flexors, scapular stabilization (2-3 sets × 10-15 reps, Borg 11-13), progressed weekly. Modalities: Hot pack 15 min at 40-45°C; TENS 80-100 Hz, 50-100 µs pulse width, 20 min. Frequency: 3× weekly for 6 weeks. Safety: contraindications screened; pain/exertion monitored pre/post.
