Data for these doses comes from: Jang H, Lee H. Meta-analysis of pain relief effects by laser irradiation on joint areas. Photomed Laser Surg 2012;30 (8):405–417.
TREATMENT 1: 830 nm
1. 830 nm, 11 mW/cm^2 continuous, 450 s (I get 4.95 J/cm^2)
2. 830 nm, 122 mW/cm^2 pulsed, 450 s (I get 54.9 J/cm^2)
1+2 combined = 5.6 J/cm^2 per joint, 2 joints (11.2 joules total)
I get 59.85 J/cm^2, 29.925 per joint
TREATMENT 2: 633 nm
3. 633 nm, 8 mW/cm^2 continuous, 450 s (i get 3.6 J/cm^2)
4. 633 nm, 34 mW/cm^2 pulsed, 450 s ( I get 15.3 J/cm^2)
4 + 5 combined = 5.1 J/cm^2 per joint, 2 joints (10.2 J total)
I get 18.9 J/cm^2, 9.45 per joint
I cannot make this math work. Not sure what the dose is.
