Synovial joint Angles of the Hip
Hailey Rubin and Angie Allen
Purpose:
To analyze the full range of motion of the hip flexion and extension by measuring the joint angles.
Methods:
We decided to use the Hudl Technique app to film hip in a squatting motion from fully extended to full flexion of the hip. The Technique app made it possible to pause the video, allowing the ability to measure the angle from the top of the Iliac crest to the knee to the ankle. We choose to record in front of the dark doors of the gym with the best lighting possible in a sagittal view to allow the best view of the hip’s range of motion and angles.
Results:
Many people do not properly perform correct squat biomechanics often leading to injury. The prime movers of a squat are the muscles around the hips and knees, but it also includes the ankle foot and lower back. Image 1 demonstrates a comfortable stance; most people prefer their feet slightly wider than shoulder width apart with their toes pointed out at a slight angle (this stance is clearly seen within the GAIT cycle). By keeping the knees at a slight lateral rotation it provides a greater balance to overcome patella maltracking. Movement from Image 1 to Image 2 is the lowering phase of the squat, the body moves from a standing position into a squat similar to sitting down in a chair. Movement occurs at the pelvis, hips, knees, and ankles eccentrically in a closed chain. The movement is within the frontal axis and it is a closed chain because of the planted feet. The pelvis tilts anteriorly activating back extensor which pull upward and hip flexors which pull downward. This …show more content…
There’s no question that the full squat is an essential and yet many people are unable to perform one. Kids have a good squat form (just watch them at play), but their parents are stiff at the hips with rounded backs and tight knee
