This study aimed to compare men and women on muscle strength, pain, physical function, and gait spatiotemporal parameters at three speeds, verifying the correlation between variables. Forty-two individuals with KOA (21 women) participated in this cross-sectional study. They were assessed using the visual analog pain scale (VAS) and Western Ontario and McMaster Universities Index (WOMAC), lower limb isometric muscle strength, and gait kinematics on a treadmill at three speeds. The results revealed that women had worse clinical measures (WOMAC and muscle strength) (p < 0.006) and reduced step length (p < 0.05). The results also showed that women had more variables correlated with step length and stronger correlations (r = 0.33 to 0.83) than men. In conclusion, the moderate to strong correlation between step length and clinical measures observed for women suggests that step length could be a suitable parameter for assessing women with KOA. Also, the critical role of clinical measures indicates that it could be beneficial to associate the usual intervention with a psychosocial approach for women.

Background and Purpose The manipulation of sensory conditions and attentional demand affect the postural sway in older adults with knee osteoarthritis (KOA). However, it is not known if emotional and sensitization status affects postural sway in this population. This study aimed to test if older adults with mild and moderate knee osteoarthritis with symptoms of depression and high sensitization would change the profile of postural sway. Methods Design: A cross‐sectional study was undertaken. Participants: The center of pressure parameters of 30 older adults with mild and moderate knee osteoarthritis and 15 healthy controls were evaluated under different conditions manipulating the visual and attentional demand. We used the pressure pain threshold to measure the sensitization status. Furthermore, we applied the Beck Depression Inventory index to assess emotional status. Results Manipulating the visual demand affected the center of pressure parameters for both groups, without differences between them. Compared to the healthy control group, the knee osteoarthritis group presented with worse scores on the Beck Depression Inventory, lower pressure pain threshold scores, and the correlations between the symptoms of depression and sensitization status ranged from weak to moderate. Finally, in the knee osteoarthritis group, we observed few and weak significant associations between the center of pressure parameters and the Beck Depression Inventory and the pressure pain threshold scores. Discussion Emotional and sensitization status seem not to be more associated with the center of pressure of older adults with mild to moderate KOA than healthy adults. Thus, it suggests that this population can safely maintain postural sway, irrespective of depression symptoms and high sensitization.
