Abstract
Change in the lower extremity kinematics in the frontal plane and muscle activation patterns have been associated with patellofemoral pain and ITB friction syndrome. Therefore to prevent this modified mechanic under these conditions, many therapeutic protocols focus on strength and increasing the Gmed activity as an effective method for control of dynamic knee valgus in various exercises for prevention and rehabilitation. Kinematic information of the lower limb by the motion analysis with 10 cameras and the electromyographic activity of Gmed and TFL muscles with the wireless electromyographic system (16-channel Myon, UK) during pedal with and without band loop in 10 pedal cycles of last 30 seconds were recorded in people with and without genu varum. The results of data analysis based on paired t-test showed that there was a significant difference in Gmed muscle activation rate and Gmed/TFL activity ratio in both groups, onset of TFL and offset of Gmed activity in the normal group, and the onset of TFL muscle activity, offset of Gmed and mean knee abduction angle in the GV group, But there was no significant difference in other variables. The results of data analysis based on an independent t-test showed that there was a significant difference between the mean TFL activation with and without the loop and the mean and maximum knee abduction angle between the two groups. The results of this study suggest that pedaling with the loop band can be an effective method to increase the function and activation of Gmed muscle while decreasing TFL, improving knee kinematics in the frontal plane and knee stability to prevent injury in the normal and GV Group.
