Treadmill Gait Analysis Part 2: FlexiTrace Parameters

In this section, a number of parameters related to Gait Analysis and the corresponding graphs from the FlexiTrace application are examined. These graphs show the changes in Hip and Knee angles in the Sagittal plane, with positive values ​​indicating Hip Flexion and Knee Flexion and negative values ​​indicating Hip Extension and Knee Extension.

• Extension is a movement that increases the angle between two body parts and usually results in a straightening of the joint.
• Flexion is a movement that decreases the angle between two body parts and usually results in a bending of the joint.

**Certain details and illustrations included in this article have been derived from the following sources: Video and PDF **

1. The maximum value of the knee angle in the stance phase: the graphs related to the knee angle can be seen on pages 3 and 4 of the gait analysis output report in this program. For the attached video, the value of this angle is about 45 degrees in different periods of walking.

2. The maximum value of the knee angle in the swing phase: for the attached video, the value of this angle in different periods of walking is about 45 degrees.

3. The minimum value of the knee angle in the stance phase: for the attached video, the value of this angle is about 15 degrees in different periods of walking.

4. The minimum value of the knee angle in the swing phase: For the attached video, the value of this angle is about 15 degrees in different periods of walking.

5. The value of the Knee angle at the moment of the start of the gait cycle: for the attached video, the value of this angle in different periods of walking is about 15 degrees

6. The minimum value of the hip angle: Hip angle graphs can be seen on pages 5 and 6 of the gait analysis output report in this program. For the attached video, the minimum Hip angle varies from -10 to -5 degrees during different gait periods. Given that negative values ​​of this angle indicate Hip Extension, by examining the minimum value, we can examine the maximum extension value of this joint.

7. The maximum value of the hip angle:Hip angle graphs can be seen on pages 5 and 6 of the gait analysis output report in this program. For the attached video, the value of this angle in different periods of walking is about 20 degrees. Given that positive values ​​of this angle indicate Hip Flexion, by examining the maximum value, we can examine the maximum Flexion value of this joint.

8. The amount of Hip angle at the time of starting the Cycle: The graphs related to the Hip angle can be seen on pages 5 and 6 of the gait analysis output report in this program. For the attached video, the value of this angle is about 20 degrees in different periods of walking.

9. Symmetry of left and right leg and range of motion of joints
