A 57-year-old female with knee osteoarthritis used the 980 nm Delta Laser to treat her right knee. After two weeks of daily treatments her Western Ontario and McMaster Universities Arthritis Index (WOMAC) score improved from 37 to 71 (0 - worst possible, 100 - best possible). An additional seven weeks of irregular treatments continued to improve the condition, leading to an overall increase in her WOMAC score by 40.5% (WOMAC score 78).
A 64-year-old male diagnosed with arthrosis with oedema (large cartilage injury Grade III-IV), used the Delta Laser (980 nm and later 905 nm) to treat his left knee. After three months of daily self-treatments most of the pain was gone and his Western Ontario and McMaster Universities Arthritis Index (WOMAC) score improved from 47 to 82 (0 - worst possible, 100 - best possible). After six months of coMra-Therapy his WOMAC score improved to 89-91 and remained at this level. After one and a half years following the onset of symptoms he treats himself only now and then when there is a minor relapse.
