Flow diagram of search strategy. OA=osteoarthritis.
Forest plot depicting standardized mean differences between participants with knee OA and healthy older adults for studies included in the review. Negative standardized mean differences indicate worse balance outcomes in the knee OA group. OA=osteoarthritis, IV=inverse variance, 95% CI=95% confidence interval, CB&M=Community Balance and Mobility Scale.
Tables
Modified Quality Indexa
↵a All items, except item 5, were scored 1 for fulfilling the criterion or 0 if the criterion were not filled. Publications that did not provide sufficient details to fulfill the criterion also were given a score of 0 for “unable to be determined,” as per instructions of the original index. Positive and negative agreements indicate level of initial agreement between reviewers prior to the consensus meeting.
b Studies had to report the outcome measure in the Method section, including a brief description of how to administer to receive a score of 1.
c Studies had to report age, sex, height and weight, or body mass index and severity of all groups to receive a score of 1.
d Studies had to report age, sex, body mass index for all groups and radiographic severity for knee osteoarthritis groups to receive full marks; a score of 1 was given if partially reported.
e Actual P values (unless <.01) had to be reported to receive a score of 1.
Results of Included Articlesa
↵a OA=osteoarthritis, 95% CI=95% confidence interval, SMD=standardized mean difference, KL=Kellgren-Lawrence scale score.
b Data presented as mean (SD), except for the study by Takacs et al for which data are presented as mean (range). For all results, higher numbers indicate higher balance ability.
