The objective of this study was to explore the impact of balance confidence on different activities of daily living (ADL) in older people with knee osteoarthritis (OA).


Forty-seven consecutive participants with knee OA were included in this cross-sectional study. They were divided according to the results of the Activities-specific Balance Confidence (ABC) Scale into a group with a low level of confidence in physical functioning (ABC < 50, n = 22) and a group with moderate and high levels of confidence (ABC ≥ 50, n = 25).


In the ABC < 50 group, the effect of pain on ADL, the physician's global assessment of the disease, and the Western Ontario and McMaster Universities Osteoarthritis Index scores were significantly higher, while quality of life (Short form-36) was lower compared to the ABC ≥ 50 group. No significant difference was found between the two groups regarding the static and dynamic balance measurements.


Older people with knee OA who were less confident in their daily physical activities had more physical difficulties and a greater effect of pain on ADL, lower quality of life, and a higher physician's global assessment, but no differences were obtained in balance tests.


In people with knee OA, decreased balance confidence is associated with more physical difficulties, an increased effect of pain on ADL, and lower quality of life. An improved awareness of decreased balance confidence may lead to more effective management of older people with knee OA by improving their mobility and QOL through rehabilitation. Furthermore, future research in that direction is warranted.
