Balance confidence and associated factors among patients with knee osteoarthritis.

Introduction: Knee osteoarthritis (KOA) is a progressive condition that results in decreased mobility, self-imposed restriction of activity, and impaired functions such as loss of self-efficacy, fear of falling, and balance impairments. This study assessed balance confidence and associated factors among patients with KOA.
Methods: This cross-sectional study involved 115 patients with KOA. The Western Ontario and McMaster University Osteoarthritis Index was used to evaluate pain, stiffness, and physical function while the Activity Specific Balance Confidence scale was used to assess the balance confidence. Pearson's chi-square test, Pearson's correlation and Spearman's rank correlation coefficient determined the association between variables.
Results: Greater number [67(58.3%)] of the participants had low levels of functioning in balance confidence. Significant associations were observed between balance confidence and pattern of KOA (X2 = 7.08, p = 0.029, φc = 0.248), fear of fall (X2 = 38.32, p = 0.001, φc = 0.577) and history of fall (X2 = 11.49, p = 0.003, φc = 0.316). Significant negative correlations were observed between balance confidence and pain (r = -0.498, p = 0.001), stiffness (r = -0.564, p = 0.01) and physical function (r = -0.676, p = 0.001).
Conclusion: The low levels of balance confidence and related factors are a cause for concern and highlight the need to assess and monitor balance confidence in KOA rehabilitation using balance confidence ratings. This could prompt the integration of physical therapy rehabilitation programs that target balance confidence and related factors to improve mobility, quality of life and outcome of rehabilitation.
