Hi All, I want a big help from you all. I have calculated the KOOS score for each pain,QOL,Sx, etc separately. If I wanna tell whether the KOOS score i got for Quality of life is good score or bad score, How can I do it? Are there any cut offs. Could you plz kindly tell me how to calculate good or bad score?. In my research I have taken Knee osteoarthritis patients.
