The gait parameters, the variability of gait, the balancing
ability are influenced by unilateral knee osteoarthritis. The
aim of this study is to analyze balancing ability after sudden
perturbation characterized Lehr’s damping ratio measured
by provocation test stance on both and on single limb at
patient with bilateral knee osteoarthritis.
20 controls, 20 patients with unilateral and 20 with bilateral
knee osteoarthritis. Balancing ability was characterized by
the Lehr’s damping ratio determined by provocation test
during double leg and single leg stance. For patients with
bilateral knee osteoarthritis, the results of provocation test
while standing on both limbs, on dominant and non-
dominant limb did not differ significantly each other. No
significant difference found between the results of males
and females. Our results showed that, the lateral dominance
and the gender did not affect the balancing ability, if the
knee osteoarthritis is bilateral. Our results showed that the
most dominant impact is the severity of osteoarthritis.
