Piriformis syndrome, although often associated with pain in the glutes and lower back, can also affect pregnant women. During pregnancy, the body undergoes significant anatomical and hormonal changes, which can influence the occurrence of this syndrome.

Introduction

The piriformis muscle, located in the pelvic region, has the capacity to compress the sciatic nerve in certain pregnant women, thus causing characteristic pain which can spread down the leg, adding additional discomfort to the mother-to-be.

Hormonal changes, including increases in relaxin, a hormone that softens tissues and ligaments to facilitate childbirth, can increase the piriformis muscle’s vulnerability to inflammation and nerve compression. This complex interplay between hormonal changes and muscle mechanics contributes to the symptoms experienced.

The hormone relaxin, produced by the ovaries and uterus, works by relaxing joints to facilitate the birthing process. However, this joint relaxation puts increased pressure on the piriformis muscle, which must intensify its work to maintain the stability of the pelvis. It is common among pregnant women to feel discomfort in the buttocks, often radiating down the leg, due to these hormonal adjustments.

The management of piriformis syndrome in pregnant women requires a delicate approach, favoring non-invasive methods adapted to the gestational period. Targeted muscle strengthening exercises, gentle stretching and postural adjustments may be considered to relieve symptoms, while taking into account the specific needs of pregnancy.

It is crucial that a pregnant woman experiencing pain related to piriformis syndrome consults her healthcare professional for an accurate diagnosis and appropriate treatment plan, ensuring the well-being of both mother and baby during this time. crucial. Early and appropriate treatment will help to alleviate the symptoms, thus improving the overall quality of life of the mother-to-be.

During pregnancy, the body must adapt to many postural changes. The center of gravity shifts forward. The lumbar and cervical curves become more pronounced and the back and shoulders round. The pelvis tilts backwards.

The hormone relaxin, secreted by the ovaries and uterus, will have the function of relaxing the joints, thus facilitating the exit of the baby. Because of this joint relaxation, the piriformis will have to work harder to keep the pelvis together. In women who are pregnant, it is common to feel discomfort in the buttocks which goes down the leg.

Piriformis syndrome

Piriformis syndrome in pregnant women is a fairly common neuromuscular disorder that occurs when it compresses the sciatic nerve. The piriformis originates on the anterior surface of the sacrum and sacroiliac joint and inserts on the greater trochanter of the hip. Its function will be to move the leg in external rotation. The sciatic nerve is under this muscle. If there is continued contraction of the piriformis, the nerve may become irritated and numbness in the leg may occur. The suffering can feel unbearable, the osteopathic treatment is excellent for the relaxation of the piriformis. It is important not to wait too long to seek help.

Pathophysiology of piriformis syndrome

Pathophysiology refers to the study of the functional changes that occur in the body as a result of a disease or pathological condition. It combines aspects of pathology (the study of the causes and effects of diseases) with physiology (the study of how the body and its systems function).

The pathophysiology of piriformis syndrome in pregnant women is linked to specific anatomical and hormonal changes that occur during pregnancy. 

Here is an overview of the pathophysiology of this particular condition:

  1. Sciatic Nerve Compression: The piriformis muscle is located near the sciatic nerve, the longest nerve in the body. During pregnancy, the expanding uterus puts pressure on surrounding structures, including the piriformis muscle and sciatic nerve. This compression can lead to irritation or inflammation of the nerve.
  2. Hormonal Changes: During pregnancy, the body produces hormones such as relaxin, which aim to relax the pelvic ligaments and muscles to facilitate the expansion of the uterus and the passage of the baby during childbirth. However, this muscle relaxation can also affect the stability of the pelvic region, which may contribute to compression of the sciatic nerve by the piriformis muscle.
  3. Postural Changes: Changes in center of gravity and posture are common during pregnancy to accommodate the growing uterus. These changes can lead to increased pressure on the lumbar and pelvic region, contributing to irritation of the piriformis muscle and sciatic nerve.
  4. Weight Management: Weight gain during pregnancy, particularly in the abdominal region, can place additional pressure on the spine and lumbar region, increasing the risk of irritation of the piriformis muscle and sciatic nerve.
  5. Prolonged Sitting: Prolonged sitting is common during pregnancy, whether at work or at home. This position can increase pressure on the piriformis muscle, worsening the symptoms of the syndrome.
  6. Increased Muscle Demand: The pelvic muscles may be used more during pregnancy due to changes in posture and the need to provide increased support for the added weight.

In summary, piriformis syndrome in pregnant women often results from a combination of sciatic nerve compression by the piriformis muscle, pregnancy-induced hormonal changes, postural changes, and weight management.

Causes of piriformis syndrome

  1. Sciatic Nerve Compression: The piriformis muscle passes just above the sciatic nerve, which is the longest nerve in the body. Physiological changes associated with pregnancy, such as pressure from the expanding uterus on surrounding structures, can compress the sciatic nerve and contribute to piriformis syndrome.
  2. Hormonal Changes: During pregnancy, the body produces hormones, notably relaxin, which function to relax the ligaments and pelvic muscles to allow the expansion of the uterus. However, it can also affect the stability of the pelvic region, thus promoting compression of the sciatic nerve by the piriformis muscle.
  3. Postural Changes: Changes in center of gravity and posture during pregnancy can put increased pressure on the lumbar and pelvic region, contributing to irritation of the piriformis muscle and sciatic nerve.
  4. Increased Load on the Lower Back: Weight gain during pregnancy, especially in the abdominal region, can increase the load on the spine and lumbar region, which can influence piriformis syndrome.
  5. Increased Muscle Activity: The pelvic muscles may be used more during pregnancy due to changes in posture and the increased need for support for the added weight.
  6. Prolonged Sitting: Prolonged sitting, common during pregnancy, can put pressure on the piriformis muscle, worsening the symptoms of the syndrome.

Symptoms of Piriformis syndrome

  1. Pain in Buttocks: Pain may be felt in the buttocks area, usually on one side only. This pain can be described as deep and throbbing.
  2. Lower Back Pain: Pain can radiate to the lower back, especially on the side where the piriformis muscle exerts pressure on the sciatic nerve.
  3. Pain Along the Sciatic Nerve: Pain can follow the path of the sciatic nerve, going down the back of the thigh and sometimes to the calf or foot.
  4. Numbness and Tingling: Sensations of numbness, tingling, or weakness may be felt along the sciatic nerve.
  5. Pain Worsened by Movement: Pain may worsen with certain activities, such as walking, sitting for prolonged periods, or certain specific movements.
  6. Pain When Sitting: Sitting can make symptoms worse, as it can increase the pressure exerted by the piriformis muscle on the sciatic nerve.
  7. Difficulty Walking: Symptoms can make walking difficult, especially if the pain is severe.

Role of Osteopathy in the Management of Piriformis Syndrome

  1. Overall Assessment: Osteopaths take a holistic approach to assessing the body as a whole. They examine posture, joint mobility, and muscle function to identify imbalances that could be contributing to sciatic nerve compression.
  2. Myofascial Release: Osteopathy uses myofascial release techniques to release tension in muscular and connective tissues. By working on the surrounding muscles, the osteopath can reduce the pressure on the sciatic nerve, thereby relieving symptoms.
  3. Joint Mobilization: Osteopaths can perform gentle manipulations to improve joint mobility. By optimizing joint function, strain on the sciatic nerve can be reduced, helping to relieve symptoms.
  4. Correction of Pelvic Imbalances: Osteopaths can work on the pelvic region to correct imbalances that could contribute to piriformis syndrome. By restoring muscle and joint balance, pressure on the sciatic nerve can be reduced.
  5. Advice on Self-Management: Osteopaths can provide advice on suitable stretching and strengthening exercises to help maintain muscle flexibility and prevent recurrence of symptoms.

It is essential to note that osteopathy does not claim to directly treat the piriformis muscle, but rather aims to improve overall body function to reduce nerve compression and relieve the symptoms of piriformis syndrome. Before starting any treatment, it is recommended to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan.

Case studies

Case Study 1: Relaxation of the Piriformis and Psoas to Relieve Pain in Mrs. L

Mrs. L, 32 years old, pregnant with her second child, consulted an osteopath because of severe pain in her lower back, buttocks and right leg. She also complained of frequent headaches. Initial examination revealed significant tension in the piriformis muscle, causing compression of the sciatic nerve.

The osteopath developed a treatment plan that included specific piriformis and psoas release techniques. When assessing Mrs. L’s posture, the osteopath noted a modified cervical curve, accompanied by tension in the suboccipital region.

Over several sessions, the osteopath worked on relaxing the piriformis, thus relieving nerve compression. Additionally, specific techniques were applied to release the tight psoas. The osteopath also took into account postural changes due to pregnancy, working on the suboccipital region to relieve frequent headaches.

After several weeks of treatment, Ms. L reported a marked improvement in her lower back, buttocks and leg pain. Headaches were less frequent, and she noticed better overall mobility.

Case Study 2: A Comprehensive Approach for Mrs. G and Her Headaches

Mrs. G, 28, pregnant with her first child, sought help from an osteopath due to persistent headaches. Initial examination revealed significant tension in the cervical region, particularly in the suboccipital region. Additionally, low back and pelvic pain were present.

The osteopath adopted a global approach, taking into account the pregnancy, by working on the relaxation of the piriformis and the psoas. By assessing Mrs. G’s posture, the osteopath identified postural changes linked to pregnancy.

Release techniques were applied to the cervical region, relieving tension in the suboccipital region. The osteopath also provided advice on posture and exercises to strengthen the supporting muscles.

Over the course of the sessions, Mrs. G noticed a significant improvement in her headaches, and her lower back and pelvic pain also decreased. She continued to attend regular sessions to support her pregnancy and maintain her well-being.

These case studies illustrate how a comprehensive osteopathic approach, including treatment of the piriformis, psoas, and pregnancy-specific adjustments, can help relieve pain in pregnant women.

Positional release treatment for the piriformis

The positional release technique for the piriformis muscle can be performed using a specific position to reduce pressure on the sciatic nerve. Here’s one method you could try, but keep in mind that every person is different, and it is always recommended to consult a healthcare professional before beginning any exercise or treatment program. In case of pregnancy, also make sure that the position is comfortable and safe for the health of the mother and baby.

Lying on your back position

  1. Lie on your back on a firm surface, such as a yoga mat or bed.
  2. Bend your knees and place your feet on the surface, hip-width apart.
  3. Lift the affected leg (the side where you feel the symptoms) and bend the knee to about a 90-degree angle.
  4. Cross the ankle of the raised leg over the knee of the other leg, forming a position similar to the letter “4”.
  5. Hold this position and breathe deeply to promote relaxation.

Duration: Hold the position for 1 to 2 minutes, or as long as you feel comfortable. You can repeat this position several times a day.

Additional Tips:

  • If you experience severe pain or discomfort, stop the position immediately and consult a healthcare professional.
  • You can use a cushion under your head for added comfort.
  • If possible, practice this technique on a firm surface for best support.

This technique aims to stretch the piriformis muscle and relieve pressure on the sciatic nerve. However, each person reacts differently, and it is always recommended to consult a healthcare professional for advice tailored to your specific situation. If you are pregnant, make sure this position is safe and comfortable during pregnancy.

Sitting position on a chair :

  1. Sit comfortably in a chair with your back straight and your feet flat on the floor.
  2. Make sure the chair is stable and you can sit with a comfortable posture.
  3. Lift the affected leg and place the ankle of that leg on the opposite knee, forming a position similar to the letter “4.”
  4. You can apply light pressure to the raised knee with the hand on the opposite side to gently increase the stretch, but don’t force it.
  5. Keep your back straight and breathe deeply to promote relaxation.
  6. Hold this position for 1 to 2 minutes, or as long as you feel comfortable.
  7. Repeat on the other side if necessary.

Additional Tips:

  • Make sure the chair is stable, and that you do not feel any severe pain or discomfort during the stretch.
  • If you have back or hip problems, adapt the position according to your comfort.
  • Don’t force the stretch, and stay within a range of motion that suits you.

This chair-sitting technique also aims to stretch the piriformis muscle and relieve pressure on the sciatic nerve. As always, if you have specific concerns or experience unusual pain, consult a healthcare professional before continuing or adjusting any stretching or relief technique.

Myofascial Release Technique for the Piriformis Using a Tennis Ball

Myofascial release (MFR) is a technique used to alleviate tension and tightness in the myofascial tissues, which are the tough membranes that wrap, connect, and support your muscles. One effective method for performing MFR on the piriformis muscle is using a tennis ball. This self-massage technique can help relieve pain and discomfort associated with piriformis syndrome. Here’s a step-by-step guide:

Materials Needed:

  • A tennis ball
  • A yoga mat or carpeted floor for comfort

Steps:

  1. Find a Suitable Area:
    • Choose a flat, comfortable surface like a yoga mat or carpeted floor where you can lie down and have enough space to move around.
  2. Locate the Piriformis Muscle:
    • The piriformis muscle is located in the buttock region, deep to the gluteal muscles. To find it, locate the bony prominence of your hip (greater trochanter) and the base of your spine (sacrum). The piriformis muscle lies between these two points.
  3. Position the Tennis Ball:
    • Sit on the floor with your legs extended. Place the tennis ball under your buttock on the side where you are experiencing discomfort.
    • Slowly lower yourself onto the ball, positioning it directly under the piriformis muscle.
  4. Apply Pressure:
    • Gently lean into the tennis ball to apply pressure to the piriformis muscle. You should feel a moderate amount of pressure but not intense pain.
    • If the pressure is too intense, support your weight with your hands and the opposite foot to decrease the load.
  5. Perform Gentle Movements:
    • Roll back and forth slowly over the tennis ball, allowing it to massage the muscle. Focus on areas where you feel tightness or tenderness.
    • You can also make small circular motions or shift your weight side to side to target different parts of the muscle.
  6. Hold and Breathe:
    • When you find a particularly tight or tender spot, pause and hold the pressure on that spot. Breathe deeply and try to relax the muscle as much as possible.
    • Hold for 20-30 seconds or until you feel the muscle release.
  7. Repeat as Needed:
    • Continue to roll and hold on different spots of the piriformis muscle for about 5-10 minutes.
    • Repeat on the other side if necessary, even if you do not feel pain there, to maintain muscle balance.
  8. Post-Release Stretch:
    • After performing MFR, it’s beneficial to stretch the piriformis muscle. A simple stretch involves lying on your back, crossing one leg over the opposite knee, and gently pulling the bottom knee toward your chest.

Tips:

  • Consistency: Perform this technique regularly, especially if you suffer from chronic piriformis syndrome or have a sedentary lifestyle.
  • Warm-Up: Consider doing a light warm-up before MFR, such as walking or gentle stretching, to increase blood flow to the muscles.
  • Listen to Your Body: Avoid causing excessive pain. The pressure should be enough to feel the muscle release, not to cause discomfort or bruising.

Using a tennis ball for myofascial release of the piriformis can be a highly effective method to alleviate tightness and discomfort. This simple, cost-effective technique can be easily incorporated into your daily routine to help manage symptoms and improve muscle function.

Caution:

Avoid direct pressure on the sciatic nerve, which passes below the piriformis. If you feel sharp pain or discomfort radiating down the leg, adjust the pressure or discontinue the technique.

Remember that myofascial release techniques must be performed with awareness and respecting your body’s responses. If pain persists, it is recommended to seek advice from a healthcare professional or qualified manual therapist who can provide personalized advice and interventions.
