WOMAC = Western Ontario and McMaster University Osteoarthritis Index
Sub-scale maximums are Pain = 20, Stiffness = 8, Physical Function (PF) = 68
Baseline scores (SD), KBA: Pain = 6.83 (4.07), Stiffness = 3.83 (2.56), PF = 30.67 (9.97); Strength Training: Pain = 9.44 (3.28), Stiffness = 4.67 (0.87), PF = 30.22
