What is Posterior Pelvic Tilt: A Guide to Causes, Symptoms, and Solutions

The concept of posterior pelvic tilt is often overshadowed by its more commonly discussed counterpart, anterior pelvic tilt. However, understanding posterior pelvic tilt is just as crucial for maintaining a healthy posture and preventing associated health issues. Usually associated with older people, we are now seeing an increasing number of younger clients with posterior tilt in our clinics. This comprehensive guide will delve into what posterior pelvic tilt is, its causes, symptoms, and effective strategies to correct it, ensuring a balanced and pain-free life.

What is Posterior Pelvic Tilt?

Posterior pelvic tilt is a postural dysfunction where the pelvis tilts backward, causing the anterior superior iliac spines (front of the pelvis) to rise and the coccyx (tailbone) to tuck under. This leads to a flattened lumbar lordosis, or a decreased natural curve of the lower back (lumbar spine). Imagine your pelvis like a bowl of water - in posterior tilt, the bowl dips back, spilling the contents backward. This misalignment affects the overall posture and can lead to various musculoskeletal complications.

Detailed Explanation:

Anatomical Perspective: The pelvis is a pivotal structure in the human skeletal system, integral for balance and support. In a posterior pelvic tilt, the alignment of the pelvic bones shifts backward. This tilt involves key muscle groups, including:

  • Tight Muscles: The hamstrings, which run along the back of the thigh from the hip to just below the knee, and the gluteus maximus, one of the major muscles of the hip, often become tight, pulling the pelvis into this backward rotation.
  • Weakened Muscles: Concurrently, the muscles that are typically weakened and underactivated include the hip flexors, particularly the iliopsoas group, which crosses the hip joint anteriorly, and the lumbar extensors, which support the natural curvature of the lower back.

Impact on Spinal Alignment: This backward tilting of the pelvis directly influences the spinal alignment, flattening the lumbar spine. Such an alteration affects the biomechanics of the entire spine, potentially leading to compensatory changes up the kinetic chain, including increased thoracic kyphosis (an outward curvature of the upper back) and forward head posture.

Joint and Musculoskeletal Implications: The posterior pelvic tilt not only alters the posture but also affects the functionality of joints and muscles. The sacroiliac joints, which connect the spine to the pelvis, may experience altered loading patterns, while the hip joints may see a decrease in their natural range of motion due to the changed orientation of the pelvis.

Understanding the anatomy and biomechanics involved in posterior pelvic tilt is crucial for identifying effective treatment and corrective exercise strategies. Addressing the muscular imbalances through targeted stretching and strengthening exercises can help in restoring proper pelvic alignment and alleviating associated discomfort or pain.

What Causes Posterior Pelvic Tilt?

Posterior pelvic tilt emerges from a complex interplay of factors, primarily muscular imbalances and lifestyle influences.

causes of posterior pelvic tilt
  • Muscular Imbalances: The imbalance between overly tight hamstrings and underdeveloped lower back and abdominal muscles sits at the core of posterior pelvic tilt. This misalignment is often exacerbated by sedentary lifestyles or focused training on specific muscle groups while neglecting others.
  • Lifestyle Factors: Extended periods of sitting with poor posture, common in today's workplace environments, significantly contribute to developing and exacerbating posterior pelvic tilt.
  • Exercise Habits: Disproportionate emphasis on certain types of exercise, such as excessive abdominal strengthening without corresponding lower back and hip flexor conditioning, can lead to a posterior tilt.
  • Ergonomic Practices: Inadequate ergonomic setups during daily activities or at work can promote poor posture, further contributing to posterior pelvic tilt.

Structural and Additional Factors:

  • Leg Length Discrepancy and Joint Restrictions: A subtle difference in leg length or limitations in the flexibility and mobility of ankle or hip joints can distort natural movement patterns, thereby impacting the alignment of the pelvis.
  • Neurological Conditions: Various conditions that affect muscle tone and control can alter pelvic positioning. This underscores the need for a thorough diagnostic approach and tailored treatment strategies.
  • Deconditioning: A decline in physical fitness and muscle strength due to inactivity can lead to or exacerbate posterior pelvic tilt. As muscles weaken, especially those in the core and lower back, the body's natural posture can shift unfavorably.
  • Aging: The aging process naturally affects the body's musculoskeletal structure, potentially leading to changes in posture. Loss of muscle mass, reduced flexibility, and the onset of conditions like osteoporosis can contribute to the development of posterior pelvic tilt over time.

In summary, posterior pelvic tilt is influenced by various factors, from muscular imbalances and lifestyle habits to structural issues and beyond. Recognizing these elements is crucial in developing effective strategies for correction and management.

What Are the Symptoms Associated with Posterior Pelvic Tilt?

Understanding the importance of posterior pelvic tilt is crucial in recognizing its impact on health and well-being.

  • Biomechanical Implications: The alteration in pelvic alignment can create strain on the lower back, disrupt spinal alignment, and affect the body's shock absorption capabilities.
  • Health Consequences: Prolonged posterior pelvic tilt can lead to chronic back pain, reduced mobility, and a heightened risk of spinal injuries.
symptoms from posterior pelvic tilt

Posterior pelvic tilt isn't just an aesthetic concern; it can have significant repercussions for a person's health and well-being in several ways:

Musculoskeletal Issues:

  • Back pain: The strain on the lower back due to the flattened arch and weakening of the erectors and hip flexors, often leads to discomfort and low back pain.
  • Hip pain: Tight hamstrings and hip extensors, weak psoas major, and other muscle imbalances due to the posterior pelvic position can cause hip pain and tightness.
  • Knee pain: The altered biomechanics can put additional stress on the knees, contributing to pain and injuries.
  • Muscle imbalances: Weak abdominal muscles and tight hamstrings can create further postural imbalances, perpetuating the tilt and increasing the risk of injuries.

Postural Problems:

  • C-Curve Spine: Characterized by an exaggerated curvature of the spine that resembles the letter "C,” it can lead to an uneven distribution of weight through the spine, stressing certain areas more than others and potentially causing pain or discomfort in the back and neck regions.
  • Swayback: Swayback posture is identified by an exaggerated forward position of the pelvis and lower back, which pushes the abdomen forward and the upper back behind the hips. This misalignment can strain the lower back, leading to discomfort and pain, and often correlates with rounded shoulders and a forward head posture, creating a chain of compensatory postural adjustments.
  • Kyphosis: Kyphosis is noted for an excessive outward curvature of the upper back, creating a hunched-back appearance. This can lead to a compression of the internal organs, breathing restriction, restricted movement of the shoulders, and chronic pain in the back due to the unnatural curvature and the body's attempt to compensate for the imbalance.
  • Knee Flexion: This condition involves a persistent slight bending of the knees when standing or walking, which can disrupt the natural alignment of the lower body. Knee flexion may cause undue stress on the knee joints and surrounding muscles, leading to discomfort, pain, and increased wear and tear over time.
  • Inhibited movement: Postural deviations are caused by and can lead to further muscle activation and tension imbalances, significantly limiting mobility and range of motion. This restriction can make it challenging to perform daily activities and exercises, contributing to a decreased quality of life and increased risk of injuries due to compensatory movements and muscle strain.

Organ Function:

  • Digestive issues: The forward-shifted pelvic position can put pressure on the intestines, potentially leading to constipation, bloating, and acid reflux.
  • Pelvic floor dysfunction: In severe cases, the strain on the pelvic floor muscles can contribute to incontinence or other pelvic floor problems.
  • Incontinence: In severe cases, it can put additional pressure on the bladder and weaken the pelvic floor, increasing the risk of leakage.

Additional Concerns:

  • Reduced lung capacity: The compressed diaphragm in severe cases can limit lung function, impacting breathing and energy levels.
  • Psychological impact: Chronic pain and postural issues can affect self-esteem and confidence, impacting mental well-being.

Frequently Asked Questions

How do you fix posterior pelvic tilt?

Addressing posterior pelvic tilt involves a combination of targeted exercises to stretch tight muscles and strengthen weakened ones. Specifically, releasing the hamstrings and gluteal muscles while focusing on strengthening (also read muscle activation) the hip flexors and lower back muscles can help restore the pelvis to a more neutral position. Incorporating core-strengthening exercises also aids in stabilizing and supporting proper pelvic alignment. Consultation with a posture specialist or a physical therapist can provide personalized guidance and an exercise program tailored to individual needs.

The mistake many people make is expecting a hamstring stretch to help. Instead, engaging the musculature in pelvic tilt exercises promoting hip flexion is critical. Focusing on just the pelvis can also lead to problems because the upper body can dictate a posteriorly tilted pelvis.

What causes posterior pelvic tilt?

Posterior pelvic tilt is primarily caused by a combination of muscular imbalances where the hamstrings and glute muscles become overly tight, pulling the pelvis backward. Conversely, weakened hip flexors and lower back muscles contribute to this imbalance. Factors such as prolonged sitting, inadequate exercise routines focusing too much on certain muscle groups without counterbalancing exercises, and poor ergonomic practices during daily activities further exacerbate this condition.

What are the long-term effects of not addressing posterior pelvic tilt?

Ignoring posterior pelvic tilt can lead to a series of long-term musculoskeletal issues. These include chronic lower back pain due to the lumbar curve's flattening, reduced spine flexibility and mobility, and a heightened risk of injuries due to compensatory movements and imbalances in the body's biomechanics. Furthermore, the altered spinal alignment can impact other areas, leading to neck and shoulder discomfort and potentially affecting overall posture and movement efficiency.

What is the difference between anterior and posterior pelvic tilt?

Anterior and posterior pelvic tilt represent opposite postural deviations of the pelvis. In an anterior pelvic tilt, the pelvis tilts forward, leading to an exaggerated lumbar lordosis or arching of the lower back. This is often due to tight hip flexors and weak abdominal muscles. Conversely, a posterior pelvic tilt involves the pelvis tilting backward, diminishing the lumbar curve, and is characterized by tight hamstrings and weakened hip flexors. Both conditions disrupt the body's natural alignment and can contribute to discomfort and dysfunction if not addressed.

Does posterior pelvic tilt make the butt appear bigger or smaller?

A posterior pelvic tilt can impact the appearance of the buttocks, making them appear flatter or less pronounced. This effect is due to the backward rotation of the pelvis, which tucks the tailbone under and reduces the natural curvature of the lower back. This alignment can diminish the gluteal muscles' prominence, leading to what some might perceive as a smaller buttock appearance. Addressing the posterior pelvic tilt through specific exercises to strengthen the glutes and correct pelvic alignment can help restore a more natural, aesthetically pleasing body posture, potentially enhancing the buttocks' appearance.


Though less talked about, posterior pelvic tilt is an important postural issue that demands attention. Understanding its causes, symptoms, and corrective measures is essential for anyone aiming to maintain a healthy posture and prevent related health issues. By adopting the right exercises, ergonomic practices, and professional guidance, it's possible to correct this tilt and lead a balanced, pain-free life.

Addressing posterior pelvic tilt through movement coaching, posture alignment therapy, and targeted exercises can help:

  • Alleviate pain and discomfort.
  • Improve posture and alignment.
  • Enhance flexibility and movement.
  • Optimize organ function.
  • Boost confidence and well-being.

Remember, early intervention and proactive management are crucial in preventing the potential complications of posterior pelvic tilt. By prioritizing your posture and seeking professional guidance, you can reclaim your body's natural balance and unlock the full potential of a pain-free, active life.
