Patients
Volunteers were qualified, and 23 patients with bilateral complaints of knee OA, who had grade 2 or 3 OA, as judged by criteria of Kellgren and Lawrence,18 based on weight-bearing radiographs, were admitted in this study. All volunteers went through a medical examination (cardiovascular, respiratory) before the study, and those who did not have any health problems that might pose a risk during the maximal test and training were included in the study. The patients had not undergone any
Patients
The selected characteristics and grade of OA in the patients were not significantly different between the groups (table 1). NOTE.

Discussion
In summary, both training groups showed marked decreases in pain scores and increases in functional capacity, as well as a significant increase in peak torque and CSA of knee muscles. Because NONTX group patients were tested twice during the 8-week period and did not display these marked changes, it is difficult to attribute the improvements in training groups to the learning curve for the tests' procedures. The improvements in functional measurements were better in the CON-ECC group,
Conclusion
Our results showed that with the training programs used in this study, it is possible to improve functional capacity and to decrease pain in the patients with knee OA 2 to 3 times better than those reported in the similar studies. However, the small number of subjects involved in the groups of our study limits the authors in making a generalization. The results indicated that concentric-eccentric–coupled isokinetic training has a slightly better influence on the functional capacity of the

All comparisons included a pain outcome, 39 a patient-reported physical function outcome [21–33,35–46,48,50–53], and 33 an objectively measured quadriceps strength outcome [19,20,22–28,30,31,33,35–42,44–46,48,51,53] (Supplementary Table 2). Significant effects in favour of ACSM exercise therapy were found when compared to passive modalities (SMD 1.76, 95% CI 0.49, 3.04; I2 = 93%), no intervention (SMD 0.93, 95%CI 0.50, 1.36; I2 = 88%) and education/self-management (SMD 0.27, 95% CI 0.07, 0.47; I2 = 2%).
