S Sixty-two individuals were recruited, and 37 (18 in CG and 19 in WBVEG) fulfilled the eligibility criteria. Sixteen volunteers did not meet the inclusion criteria (14 participants did not have KOA and 2 had rheumatoid arthritis), and 9 were excluded (3 participants used corticosteroids, 1 with a tumor on the chest, 1 with a hip prosthesis, 1 with osteonecrosis, 1 with [PERSON]'s disease, 1 with recent surgery on the lumbar spine, and 1 with recent surgery on the anterior cruciate ligament). All participants of both groups completed the study, and no discomfort was reported. The development of the study, considering each stage, is shown in Figure 6.  
Figure 6: Flow diagram with the development of the study. Considering WBVEG, 2 individuals did not have bilateral KOA, 10 individuals presented Grade 1, 5 individuals presented Grade 2, and 3 individuals presented Grade 5 in the right knee. In the left knee, 10 individuals were Grade 1, 5 individuals were Grade 2, 1 individual was Grade 3, and 2 individuals were Grade 5. Concerning CG, all individuals had bilateral KOA, 13 individuals presented Grade 1, 2 individuals presented Grade 2, 1 individual presented Grade 3, and 2 individuals presented Grade 4 in the right knee. In the left knee, 11 individuals were Grade 1, 4 individuals were Grade 2, 1 individual was Grade 3, 1 individual was Grade 4, and 1 individual was Grade 5. Analyzing the baseline characteristics of KOA subjects regarding sex, waist circumference, body mass, body mass index, height, age, ODI, LFI, and VAS, no significant differences were observed between CG and WBVEG, confirming the homogeneity of the sample (Table 1). Considering the radiographic images, no statistical difference was found between CG and WBVEG as well: (i) Ahlback classification--knees right (\(p\) = 0.105) and left (\(p\) = 0.840), (ii) covarthrosis--hips right (\(p\) = 0.696) and left (\(p\) = 1.000), and (iii) Lumbosacral spine--decrease in intersonatic space (\(p\) = 0.696), interapophyseal arthrosis (\(p\) = 1.000), degenerative spondylolisthesis (\(p\) = 1.000), and degenerative scoliosis (\(p\) = 1.000). Analyzing nutritional monitoring (\(p\) = 1.000) and practice of physical activity (\(p\) = 0.453), similarly, no difference was found between CG and WBVEG. Concerning existing comorbidities, again, no difference was found between CG and WBVEG: arterial hypertension (\(p\) = 0.277) and type 2 diabetes mellitus (\(p\) = 0.180). Considering the pain level assessment (VAS), there was a significant decrease after the WBVEG intervention and between groups (Table 2). Regarding the functionality assessment (TUG test and ATF measurement), significant improvements were found before and after the CG and WBVEG interventions and between groups in the TUG test, and a significative difference was obtained before and after the WBVEG intervention and between groups in the ATF test (Table 2). \begin{table}
