Muscle imbalance (front and back thigh muscles) in relation to pelvic tilt.
introduce
pelvic tilt:
Pelvic tilt refers to the position of the pelvis relative to the body.
● Pelvic tilt is a common cause of lack of stability, flexibility, postural and motor control.
● If the pelvis is out of position then it will usually tip to one side and can cause many other disruptions in the kinetic chain.
muscle imbalance Considered to be the main cause of motor dysfunction.
In many pelvic tilt problems, the hip flexors and extensors are severely affected. Because these muscles attach to the pelvis and lower back.
**These muscles include but are not limited to:
● psoas major
● Rectus femoris.
● Quadratus.
“These muscles directly affect the lower back area and affect posture for better or worse.”
Poor core stability leading to pelvic tilt?
Weak core muscles can lead to anterior pelvic tilt, increasing lumbar lordosis.
● Some of the main causes of anterior pelvic tilt are poor posture and a sedentary lifestyle, especially for prolonged periods of time.
Types of pelvic tilt problems:
There are three most common types of pelvic tilt disorder.
● The way forward.
● Posterior.
● Pelvic tilt.
Tip: Each type of pelvic tilt indicates the direction of pelvic fixation.
- Anterior pelvic tilt:“APT” rotates the front of the pelvis forward and the back of the pelvis upward. For example, APT occurs when the hip flexors shorten and the hip extensors lengthen. This is called “lumbar hyperlordosis”
- Retroverted pelvis: “PPT” when the front of the pelvis rises and the back of the pelvis sinks. For example, PPT occurs when the hip flexors lengthen and the hip extensors shorten, specifically the gluteus maximus, which is the primary extensor of the hip joint.
- Pelvic tilt: “LPT” It leans to one side, to the right or to the left, and is Scoliosis Or people with inconsistent leg lengths (one hip is taller than the other). It can also occur when one leg is bent while the other is held straight, “in which case, as the knee is lowered toward the ground, the hip on the bent side follows the femur and causes a unilateral muscular imbalance throughout the body .
Common causes of pelvic tilt problems:
Pelvic tilt develops through movement and some inactivity.
- anterior pelvic tilt show:
● Tighten the hip flexors.
● Hamstring weakness.
● Weak gluteal muscles.
● The core is weak.- APT results for tight hip flexors.
- When a muscle tightens, it shortens.
- When the hip flexors shorten, the hip extensors lose or lengthen.
- Hip flexors such as the iliopsoas, sartorius, and rectus femoris attach to the pelvis and lower back.
- Mechanism of anterior pelvic tilt:
- Because of where the muscles originate and where they attach, they function to flex the hip joint.
- Prolonged sitting and poor posture can keep the hips curved for long periods of time. Curving the hips rotates the front of the pelvis forward and the back of the pelvis upward. This postural mechanism may predispose a person to an anterior pelvic tilt. It is common during pregnancy and considered necessary for childbirth.
- retroverted pelvis show:
● Firm buttocks.
● Tight hamstrings.
● Weak front chain.
Mechanism of posterior pelvic tilt.
PPT occurs when the front of the pelvis tilts up and back, tight hamstrings and hips pull the floor of the pelvis down beneath the body. Tight abdominal muscles pull up on the pelvis, while weak lower back muscles don’t respond.
- pelvic tilt express:
Tension in the quadratus lumborum.
LPT can make one leg appear shorter than the other, and the quadratus lumborum is the primary muscle responsible for creating and correcting pelvic tilt.
The mechanism of LPT:
The quadratus lumborum is located deep in the abdominal wall where it connects to the pelvis and lumbar spine.
The main function of this muscle is lateral flexion, “bending from side to side.” This will help stabilize the pelvis. When this muscle tightens on one side of the spine, it begins to pull the pelvis up on the other side, creating a lateral pelvic tilt.
Special examination of pelvic tilt
Anterior Pelvic Tilt Test:
Body checkup: This includes having to bend over, lie flat and stand up straight.The doctor touched the spine and
The pelvis as part of the initial examination.
thomas test:
With the patient lying supine on an examination table, the therapist assesses the ability to extend the legs, one by one, alternating knee to chest, to see if the resting leg touches the table.

** Patient flexibility and tightness of muscle groups may provide a positive (+ve) result for the Thomas test.
Best Exercises for Pelvic Tilt Correction:
1.half kneeling hip extension : Extend the right leg out in front of you and lunge until the left knee rests on the ground. Tighten your glutes and abs to tilt your pelvis forward. Lean forward until you feel tension in the hip flexor and inner thigh of your left leg. Hold for 30 seconds. Repeat 5 times on each side.
2. BRidge movement: Lie on your back with your legs bent, your feet flat on the floor, hip-width apart, and your arms at your sides. Lift your pelvis off the floor and press your heels into the floor until your upper body and thighs form a straight line. Hold for 2 seconds, slowly lower, repeat 8 to 12 times.
3. squatting: Stand with feet shoulder-width apart, toes pointing forward. Lower yourself into a sitting position until your thighs are parallel to the floor. Keep your back in a neutral position. Push up to a standing position and move the pelvis forward slightly by contracting the glutes. Repeat 15 to 20 times.
4. Pelvic tilt: Lie on your back on the floor with your legs bent and your feet flat on the floor. Draw the navel inward toward the spine and push the pelvis up toward the ceiling. Tighten your glutes and glute muscles as you tilt your pelvis forward. Hold for 5 seconds. Do 5 sets of 20 repetitions.
Relationship of hamstrings to pelvic tilt
The hamstrings attach to the pelvis?
The hamstrings connect to the ischial tuberosities, the small bony protrusions at the bottom of the pelvis, just below the buttocks.
● The hamstring muscles attach to the back of the thigh.
** The hamstrings stabilize the pelvis in the sagittal plane by controlling anterior pelvic tilt during dynamic posture and trunk flexion.
Can tight hamstrings affect the pelvic floor?
The hamstring muscles attach directly to the pelvis.
When they’re tight, they pull on the pelvis and tip it back into a retroversion.if
The calves and hamstrings are tense.
**Pelvic sagging, anterior pelvic tilt, and underextended hips can all lead to overuse of the hamstrings.
