Effect of Step Width and TOA on Q-Angle and CTA in Walking

This study was performed to examine the correlation between calcaneus to tibia angle and Q-angle, and the effects of step width and toe out angle on the calcaneus to tibia angle and Q-angle. The age of participated subjects was from 19 to 29 years(Mean=22.95, SD=2.23) who have no significant orthopedic and neurological dysfunction. The marking tapes for measurement of Q-angle and calcaneus to tibia angle were placed on seven location of each subject. Video data were collected while the subject walked on a walking grid. The result as follows : 1. There were significant differences in the step width, toe out angle, and Q-angle but not calcaneus to tibia angle between male and female. 2. There were significant differences in toe calcaneus to tibia angle and Q-angle n step width increased, respectively. 3. There were significant differences between tee out angle and calcaneus to tibia angle but not toe out angle and q-angle. 4. There was statistically significant correlation between calcaneus to tibia angle and Q-angle.
