Question

1. If both hips have iliopsoas tightness how will that affect the position of the pelvis? What will that do to the position of the lumbar spine? What about bilateral hamstring tightness?
2. What happens if someone has a weak gluteus medius? What is this called?
3. If someone has a weak gluteus medius, describe three exercises you could have them do to increase the strength of the muscle.
4. Analyze the muscles working during a static lunge in the descending and the ascending phases. Include agonists, antagonists, stabilizers, planes of motion, axes, and type of muscle contraction.

Answer 1

ANS) Iliopsoas are flexor muscles situated on the inside of hip area at the hip joint, helping in flexing the thigh . So, if both the hips have iliopsoas tightness it will make the pelvis in a tilted position because of the pulling down and forward of the hip flexors making the lower back compressed too.

The tightening of the iliopsoas causes lordosis of the lumbar region that is the back and the front sides of the intervertebral disc will vary in their thickness which will make lumbar region to arch or curve more.

Hamstrings are muscles that are present at the back side of our thigh, thus bilateral hamstring tightness occurs due to tilting od the pelvis which causes tension on hamstring muscles making them stiff. This usually happens in atheletes.

A weak gluteus medius is called Trendelenburg Gait, which leads to a condition where there occurs dropping down of the left hip when someone is standing on their right leg. Hence, making a person unable to run and walk.
