ILIOPSOAS

• Origin

Psoas major: Transverse processes of the lumbar vertebrae

Iliacus: Iliac fossa of the pelvis

• Insertion

Lesser trochanter of the femur

• Agonist(s)

- Rectus femoris

• Antagonist(s)

- Gluteus maximus

• Function

Hip flexion, hip external rotation, lumbar spine stabilization

TRIGGER POINT(S)

• Location

Trigger points can be found along the length of the muscle, particularly near the lumbar vertebrae and the inner pelvis.

• Pain Referral Pattern

Pain may refer to the lower back, anterior hip, groin, and sometimes down the front of the thigh.

It can cause aching, burning, or sharp pain in the lower back and hip region, and may contribute to discomfort or restricted movement in the hip and lower back.

• Potential Causes

• Overuse or repetitive activities involving hip flexion, such as running, cycling, or certain gym exercises.

• Prolonged sitting or sedentary lifestyle.

• Muscle imbalances between the iliopsoas and other hip and core muscles.

• Trauma or injury to the lower back or hip area.

• Prevention Tips

• Use proper techniques and form during hip flexion and core exercises to avoid overloading the iliopsoas.

• Incorporate regular stretching and strengthening exercises for the hip and core muscles.

• Ensure proper warm-up and cooldown routines before and after exercise.

• Maintain good posture and ergonomics during daily activities.

• Ensure balanced strength training to avoid muscle imbalances.
