Low-Dose Laser Acupuncture
Low-dose laser acupuncture delivered using an AlGaAs laser device (Aculas-AM-100 Multi-channel Digital LLLT System; 780 nm; 80 mW). Laser modules are taped to 10 bilateral acupoints. Active laser dose is 4.19 J/cm³ delivered over 20 minutes (1200 s) with a 3 cm² treatment area. Core acupoints: BL23, BL24, BL25, BL40; optional (one pair) for concomitant pain: BL17 or BL52 or BL37. Up to 6 sessions (week 3) with option to continue to 12 sessions (week 6).
Sham Laser Acupuncture
Sham laser acupuncture: laser modules are taped to the same 10 bilateral acupoints and sessions follow the same schedule as the active group, but the laser is not activated (no laser energy delivered). Participants cannot see the modules/machine while lying face down.
