Physiotherapy plays a crucial role in the management of various musculoskeletal and neurological conditions. One of the techniques that physiotherapists often employ is nerve stretching, also known as neural mobilization or neurodynamics. This technique aims to relieve pain and improve function by addressing restrictions and dysfunctions in the nervous system. In this blog, we will explore the various nerve-stretching techniques used in physiotherapy and their effects on pain relief.
Understanding Neural Tension and Dysfunction
The nervous system, comprising the brain, spinal cord, and peripheral nerves, is a continuous and dynamic structure that can be affected by mechanical and physiological stress. Nerves need to glide and stretch as we move, and any restriction in this movement can cause pain and dysfunction. This can result from injuries, postural issues, repetitive strain, or even systemic diseases like diabetes.
When nerves are unable to move freely, they can become irritated or compressed, leading to symptoms such as pain, tingling, numbness, and muscle weakness. Neural mobilization techniques aim to restore normal nerve function by improving mobility and reducing tension.
Common Nerve Stretching Techniques
1: Sliders (Gliders): This technique involves moving the nerve back and forth within its sheath without increasing tension significantly. It’s like flossing the nerve gently to improve its mobility. For example, in the case of the sciatic nerve, the patient may lie on their back and alternately flex and extend the hip and knee while keeping the ankle dorsiflexed and plantarflexed.
2: Tensioners: Unlike sliders, tensioners involve elongating the nerve to increase its tension. This technique is more intense and is used to address more stubborn adhesions or restrictions. For the median nerve, this might involve extending the wrist and fingers while keeping the elbow straight and moving the arm away from the body.
3: Oscillations: These are rhythmic, small movements that aim to gently mobilize the nerve without provoking pain. They can be useful for patients who are very sensitive or in acute pain.
4: Positional Release: This technique places the body in positions that slacken the nerve, allowing it to “breathe” and reduce irritation. For example, lying down with a pillow under the knees can help relieve tension on the sciatic nerve.
5: Active and Passive Techniques: Neural mobilization can be done actively, where the patient moves their own limbs, or passively, where the physiotherapist performs the movements. The choice depends on the patient’s condition and tolerance to movement.
Effects on Pain Relief
1: Reduction in Pain and Sensory Symptoms: Neural mobilization can significantly reduce pain and sensory disturbances such as tingling and numbness. By restoring normal movement and reducing mechanical stress on the nerves, these techniques can alleviate irritation and inflammation, leading to symptom relief.
2: Improved Range of Motion: By addressing restrictions in nerve movement, patients often experience an improvement in their range of motion. This is particularly important for activities of daily living and functional tasks that require flexibility and mobility.
3: Enhanced Muscle Function: Nerve stretching can improve the function of muscles innervated by the affected nerves. As nerve function is restored, patients often report improved strength and coordination in the affected muscles.
4: Reduced Inflammation: Neural mobilization can help reduce local inflammation by improving blood flow and reducing mechanical stress on the nerve. This can further aid in pain relief and promote healing.
5: Improved Quality of Life: By reducing pain and improving function, neural mobilization can have a significant positive impact on a patient’s quality of life. Patients can return to their normal activities and hobbies with less discomfort and more confidence.
Considerations and Precautions
While neural mobilization can be highly effective, it is important to approach it with caution, especially in certain patient populations. Patients with severe nerve compression, acute inflammation, or systemic conditions like rheumatoid arthritis may require modified or gentler techniques. It is also crucial for physiotherapists to thoroughly assess each patient to identify the source of nerve tension and tailor the treatment accordingly.
