The proportion of participants in each WOMAC Pain group reporting 0, 1, and 2 or more functional limitations. The four basic functional limitations analyzed include poor range of motion (self-reported flexion greater than or equal to 1000), limitations in work or housework (moderate or greater limitations), limp (moderate or greater), or being unable to walk more than 5 blocks. The number of these functional limitations reported (0, 1, or 2 or more) was associated with WOMAC Pain group (p < 0.001)
