Introduction to the sciatic

Sciatica is a neurological condition that there is a growing interest in the medical field because of its high incidence and its significant impact on quality of life. This condition is characterized by severe pain that radiates along the sciatic nerve, the largest nerve in the human body. The sciatic nerve originates in the lumbar region of the vertebral column and extends to the legs. The pain associated with sciatica can be triggered by a variety of causes, including disc herniation, spinal stenosis, or even factors related to lifestyle such as physical inactivity or obesity. It is crucial to understand that sciatica is not a diagnosis in itself but rather a symptom of an underlying problem that requires a careful medical assessment for an accurate diagnosis. The identification of the exact cause is essential to develop an effective treatment plan, which can vary from osteopathy to the injection, by way of non-invasive methods such as decompression neurovertébrale.


The importance of a multidisciplinary approach in the treatment of sciatica can not be under-estimated. Because of the complexity of the symptoms and of the multiple factors that may contribute to this condition, a full assessment by health professionals experienced is often necessary. This may include testing of medical imaging such as x-ray or MRI scan, and functional assessments and neurological disorders. Treatment of sciatica is often a long-term process that requires a combination of therapies and lifestyle changes. The decompression neurovertébrale, for example, is a non-invasive method that has shown promising results in the relief of symptoms of sciatica. This technique uses tensile forces to reduce the pressure on the spinal discs, which can in turn reduce the irritation or compression of the sciatic nerve. In sum, the sciatic nerve is a complex condition which requires medical care provided to complete for a successful treatment.


Treatment of sciatica with the decompression neurovertébrale


Sciatica is an intense pain that affects the sciatic nerve, which extends from the lower back to the legs. This condition can be caused by several factors, such as a herniated disc or spinal stenosis. The decompression neurovertébrale is a non-invasive method that can help reduce the symptoms of sciatica.


Treatment of sciatica is complex, since the signs and symptoms of this condition associated with the irritation of the sciatic nerve can be caused by a variety of causes. In most cases, an experienced health professional will know how to recognize the signs and symptoms of sciatica and recommend a medical imaging (x-ray and/or MRI) that will be needed to establish a clear diagnosis and to treat the exact cause of the sciatalgie.

What is sciatica ?


Sciatica describes symptoms of pain that originate in the lower back and radiate to the back of the leg. This is not a diagnosis in itself but rather a symptom of an underlying problem in the lower back, such as a herniated disc, bulging disc, degenerative disc disease (e.g. Degenerative disc disease), spondylolisthesis, or spinal stenosis.


Sciatica usually accompanied by pain in the lower back, but can be more severe and may occur only. Therefore, pain in the hip or knee does not necessarily mean that there is a condition causing pain on the spot : this pain may actually be caused by a pinching or irritation of the sciatic nerve that causes pain radiating away from its point of origin.



What is the sciatic nerve ?


The sciatic nerve is the largest nerve of the body, composed of nerve roots that originate in the lumbar region of the spine, and then combine more down to form the " sciatic nerve ". The symptoms occur when the large sciatic nerve is irritated or compressed at the point of origin or close to it.


What is the path of the sciatic nerve ?


  1. The pain or symptoms (numbness, tension, heaviness, burning, weakness) follow the course of the sciatic nerve that originates in the lumbar region of the lumbar spine (e.g., L5-S1) and descends into the leg through:
    • The middle part of the buttock,
    • The posterior surface of the thigh,
    • The posterior surface of the leg (calf),
    • The heel and the sole of the foot and the toes.
  2. The route may be incomplete, that is to say, you can feel the pain or the symptoms along the sciatic nerve, or only a part (e.g. Wrong only to the calf). This will mostly depend on the way in which the nerve is pinched or irritated.


How to manifest sciatica ?


  1. The sciatic rarely occurs before the age of 20 years and is becoming more common in middle age : It is the most likely to develop around 40 or 50 years.
  2. Perhaps because the term sciatica is often used to describe vaguely a pain in the leg, the estimates of its prevalence vary considerably. Some researchers have estimated that it will affect up to 43% of the population at a given time.
  3. Often, sciatica, is not caused by an event or an injury but is likely to develop over time.
  4. The vast majority of people who suffer from sciatica will feel better in a few weeks or a few months, and will get a relief of their pain with non-surgical treatments such as manipulation or the Spinal decompression therapy. For others, however, the sciatica pain can be severe and debilitating.
  5. It is advisable to consult a doctor if you suffer from a sciatica pain, on the one hand to learn how to relieve this pain, but mainly to verify the possibility of a medical problem more serious such as the herniated disc.


Suffering from sciatica ?


There is no exact data on the incidence and prevalence of sciatica. In general, it is estimated that 5% to 10% of patients with low back pain have sciatica, while the prevalence of low back pain during the lifetime ranges from 49% to 70%. The annual prevalence of the sciatic nerve related to the disk in the general population is estimated at 2.2%. Some risk factors, personal and professional to the sciatic nerve have been reported, including age (more frequent between 45 and 64 years of age), the size (the largest are affected by it benefit), mental stress, smoking, intense physical activity (for example, a lifting loads frequently, especially in flexion, and in torsion) and exposure to vibration of the vehicle (including the vibration of the whole body). The evidence of an association between the sciatic nerve and the sex or the physical condition is contradictory.

Symptoms of sciatica

The symptoms of sciatica include a throbbing pain in the lower back and legs, numbness and tingling in the lower extremities. The pain may be so intense that the patient has difficulty standing or walking. The symptoms may vary depending on the severity of the condition.


In addition to these classic symptoms, other manifestations may also be present. For example, some patients may experience muscle weakness in the leg affected, which can make it difficult to perform simple tasks such as climbing stairs. There may also be a burning sensation or heat along the path of the sciatic nerve, which typically extends from the buttock down to the foot. In some cases, the symptoms may be unilateral, affecting only one leg, while in others, they may be bilateral.


It is also important to note that sciatica can be aggravated by certain movements or positions, such as sitting for long periods of time, stooping or lifting heavy objects. In addition, factors such as stress and lack of exercise may contribute to the intensity and duration of symptoms.


In summary, sciatica is a disease complex with a wide range of symptoms that can have a significant impact on the quality of life of the patient. A full medical assessment is therefore essential for an accurate diagnosis and an effective treatment plan.


The 8 symptoms of sciatica or sciatalgie:

  1. Acute pain can make it difficult to stand or walk
  2. Constant pain in only one side of the buttock or leg (rarely in both legs except in the case of a herniated disc central)
  3. Pain that is worse when sitting
  4. Pain that radiates down the leg and sometimes into the foot and toes (it rarely happens only at the level of the foot)
  5. Leg pain that is often described as a burning, tingling or tightness
  6. Weakness, numbness, or difficulty moving the leg, foot and / or toes
  7. Although symptoms can be painful and potentially debilitating. It is rare that there is permanent damage to the sciatic nerve and the involvement of the spinal cord is possible but rather unlikely.
  8. Sciatic pain can vary from a rare and irritating to constant and incapacitating.


Muscle weakness

La faiblesse musculaire dans le contexte de la sciatique est souvent le résultat d’une compression ou d’une irritation du nerf sciatique, qui peut avoir diverses étiologies, y compris une hernie discale, une sténose spinale ou une inflammation. Cette faiblesse peut se manifester de différentes manières, allant d’une légère difficulté à lever le pied (phénomène connu sous le nom de «drop foot») à une incapacité plus sévère à effectuer des mouvements de flexion ou d’extension. Il est crucial de noter que la faiblesse musculaire peut entraîner une atrophie musculaire si elle n’est pas traitée rapidement. L’évaluation clinique et les études d’imagerie, comme l’IRM ou la tomodensitométrie, sont souvent nécessaires pour un diagnostic précis, et la prise en charge peut inclure des interventions allant de la décompression neurovertébrale à la chirurgie, en fonction de la gravité et de la cause sous-jacente.


Functional Limitations

The functional limitations associated with sciatica can have a significant impact on the quality of life of an individual. These limitations may include a reduction of the mobility, difficulty in sitting or standing for long periods of time, and even challenges in carrying out daily activities such as walking or climbing stairs. These limitations are often the result of an intense pain, a muscle weakness, or a combination of the two. It is essential to adopt a multidisciplinary approach to manage these symptoms, which can include anti-inflammatory medications, procedures, decompression neurovertébrale and osteopathy, and in more severe cases, surgical procedures. The main goal of treatment is to reduce pain, improve function and prevent complications in the long term.


Causes of sciatica

Common causes of sciatica include a herniated disc, bulging of the disc, a spinal stenosis, foraminal stenosis, spondylolisthesis, and nerve compression due to strained muscle or trauma. People suffering from obesity and a sedentary lifestyle are also more likely to develop this condition.

Diagnosis of sciatica

The diagnosis of sciatica often involves a physical examination and a complete medical evaluation of the patient's medical history. Imaging tests such as x-ray or MRI may be needed to confirm the diagnosis.



The Magnetic Resonance Imaging (MRI) is often considered the examination of choice for the accurate diagnosis of sciatica, especially when you suspect a herniated disc or spinal stenosis as the underlying cause. The MRI scan uses magnetic waves to create detailed images of internal structures of the body, including the spinal discs, nerves and surrounding soft tissues. This makes it possible not only to accurately locate the place where the sciatic nerve is compressed or irritated, but also to determine the severity of the condition. In contrast to other imaging methods, MRI does not require the use of X-rays, which makes it a safer option for patients, especially those who are pregnant or who have metal implants.



The x-ray, commonly referred to as x-rays or standard X-ray, is another method of imaging used in the diagnosis of sciatica, although it is generally less accurate than MRI for conditions related to the nerves and discs. X-rays use X-rays to create images of the bony structures, which can be useful for identifying abnormalities such as fractures, tumors or signs of arthritis, which could contribute to the sciatic nerve. However, x-rays are limited in their ability to visualize soft tissues such as the spinal discs or nerves, which may require further tests for a complete diagnosis. In general, the x-ray is often used in addition to the MRI to get a complete picture of the condition of the patient.



The electromyogram (EMG) is a diagnostic technique to be essential in the evaluation of the sciatic nerve. This is a review electrophysiological measures the electrical activity of muscles in response to nerve stimulation. The EMG can help to localize the site of nerve injury and to differentiate peripheral nerve damage infringement is central. It may also be useful to assess the severity of the injury, and track progress over time. The procedure is generally performed in conjunction with other diagnostic tests such as MRI, to provide a comprehensive assessment of the condition of the patient.

Tests of mobility

Tests of mobility are also crucial in the diagnosis of sciatica. These tests evaluate the flexibility, strength and movement of the joints and muscles of the back and lower limbs. Tests such as the test of Lasègue, which implies a passive elevation of the right leg while keeping the knee extended, can be particularly revealing. A pain that radiates along the sciatic nerve during this test is often an indicator of sciatica. Other tests of mobility can include assessments of the flexion, extension and rotation of the spine. These tests not only help to confirm the diagnosis, but also to plan a suitable treatment for you.


Treatment of sciatica

The Spinal decompression therapy is a non-invasive method that consists of stretching a gradual and controlled from the spine to reduce pressure on the nerve endings and the intervertebral discs. This technique can help relieve the symptoms of sciatica without the use of invasive treatments such as surgery.

In addition to this, there are also other options to effectively treat this condition as taking anti-inflammatory drugs non-steroidal (NSAIDS) and/or anti-pain, or injections, according to the opinion of your doctor, to relieve the pain.


What is the best treatment for sciatica ?


Il n’existe pas un seul traitement «miracle» pour un douleur sciatique mais bien plusieurs différents traitements dépendamment de la cause de la sciatique. Et pour déterminer la cause exacte de vos douleurs sciatiques, il faut dans certain cas faire des radiographies ou une résonance magnétique : ceci dépendra de votre historique, de la présentation de vos symptômes et de l’examen physique.


The optimal treatment for sciatica depends on a full clinical assessment, which may include imaging tests such as x-rays or MRI, as well as a thorough physical examination and a detailed medical history. This multidimensional approach is crucial to identify the underlying cause of the sciatica, whether it's a herniated disc, spinal stenosis, a spondylolisthesis or other medical conditions.


Treatment Options

  • - Conserving Therapy: For mild to moderate cases, a conservative approach is often recommended as the first line. This may include medication nonsteroidal anti-inflammatory drugs (NSAIDS) or muscle relaxants.
  • Corticosteroid Injections: For the pain more severe or persistent, injections, epidural corticosteroids may be considered. These injections can reduce inflammation around the sciatic nerve.
  • Surgery: In extreme cases where the methods of conservative and have failed or if the patient has neurologic deficits, surgical intervention such as microdiscectomy or laminectomy may be necessary.
  • Spinal decompression therapy: This non-invasive technique uses tensile forces to relieve pressure on the spinal discs, which can be especially useful for herniated discs.
  • Complementary and Alternative medicine: Approaches such as chiropractic, osteopathy and naturopathy can also be effective, especially when they are combined with other forms of treatment.
  • Management Style of Life: Changes in the mode of life, like weight loss, good posture, and strengthening exercises may also contribute to the management of sciatica in the long term.


Choice of Treatment

The choice of treatment should be individualized and based on several factors, including the severity of the symptoms, the underlying cause of the sciatica, and the preferences of the patient. A multidisciplinary approach involving specialists in orthopedics, neurology, and pain medicine can often provide the best results. It is also crucial to monitor the evolution of symptoms and re-evaluate the treatment plan accordingly, which may require adjustments to or changes in treatment modalities.


En résumé, il n’y a pas de «meilleur» traitement universel pour la sciatique; plutôt, le traitement le plus efficace sera celui qui est le mieux adapté à la condition médicale spécifique du patient, à son niveau de douleur, et à son style de vie. Une évaluation médicale complète est donc essentielle pour élaborer un plan de traitement personnalisé et efficace.


Here's a comparison table that shows the various causes of sciatica and the treatment options available, as well as their overall effectiveness. It is important to note that the effectiveness of each treatment can vary depending on the specific cause of the sciatica and the state of the general health of the patient.

Treatment of sciatica by decompression neurovertébrale


If sciatica is caused by a problem disc (disc herniation, protrusion, bulging of the disc, pinch disc or drying), which can be diagnosed with magnetic resonance imaging (MRI) or ct scan (scan), or when it is due to a stenosis or spondylolisthesis, the treatment of decompression neurovertébrale turns out to be a treatment more effective.

However, if the neurological symptoms become too much, as the loss of sensitivity or mobility almost full of the leg, it should not neglect these signs and consult immediately a doctor in the emergency to be taken care of quickly before irreversible damage occurs. Your condition may require surgery at the level of the lumbar region of the spine.

Treatment of sciatica by osteopathy


In the case where the sciatic nerve may be caused by a problem with bad posture, posture, posture dysfunction articular sacroiliac joint dysfunction joint of a lumbar vertebra, misalignment of a vertebra lumbar spine, misalignment of the pelvis, sprained, or pregnancy, the treatment of osteopathy offers excellent results.


Synergy Methods

The synergy between osteopathy and decompression neurovertébrale offers a treatment approach particularly powerful for the management of sciatica. This harmonious combination maximizes the benefits of each method, creating an amplified effect that goes beyond what each treatment could accomplish individually.

  1. Add-Optimal: Osteopathy acts as a perfect supplement to the decompression neurovertébrale. By improving the mobility of the joints and reducing muscle tension, osteopathy creates an environment in the body to be more favorable for decompression, making the latter more effective.
  2. Increased Efficiency: Decompression neurovertébrale, by specifically targeting the area of nerve compression, has greatly improved condition of the musculoskeletal system prepared by osteopathy. This allows the release of more effective sciatic nerve.
  3. Maintenance of Benefits: Synergy does not stop at the initial intervention. The sessions of osteopathy in follow-up may help to consolidate and maintain the gains achieved through the decompression, providing a recovery that is more sustainable.
  4. Personalized Approach: The combination of the two treatments allows for maximum customization of the care plan. Osteopathy and decompression neurovertébrale can be adjusted according to the evolution of the patient, providing a flexible response and adapted to the specific needs of each individual.
  5. Overall reduction of Symptoms: The complementarity of the two approaches allows not only to target the underlying cause of the sciatica, but also treat the associated symptoms, such as inflammation and pain, a more comprehensive and integrated.

In sum, the synergy between osteopathy and decompression neurovertébrale creates a dynamic treatment that capitalizes on the strengths of each method, thus providing a more complete solution and effective for the treatment of sciatica. As always, it is crucial to consult a health professional for an accurate diagnosis and an individualized treatment plan.
