The purpose of current study was to investigate the spatio-temporal gait parameters and knee varus angle
during walking at different speeds in young with knee varus. 18 subjects with varus deformity classified at
grade 3 of bowleg and 17 healthy subjects, volunteered to participate in this study. The following variables
include stance, swing, double support and cycle time, cadence, stride length, angle of varus at the heel
contact, midstance and toe off when walking on the treadmill at speeds of 80, 100 and 120 percent of
preferred walking speed, were measured from using the three-dimensional motion analysis system with six
optoelectronic cameras. The results of between-group tests showed that spatio-temporal gait parameters
in the varus group is similar to the normal group. Also varus angular variables in varus group, was indicate
higher values in comparison to the healthy group, but there were no significant differences. The results of
inter-group tests also showed the knee varus angle generally increases with increasing speed, that none of
the differences were not significant. According to the results, the increase in walking speed will caused to
increase knee varus angle. Therefore, walking with speed less than the normal walking speed, probably is
a suitable solution to reduce the loads exerted on the knee joint and prevention of premature osteoarthritis
in young with knee varus.
