Questions about rehabilitation for herniated discs and lumbar traction?


Hello, doctor.
I have a herniated disc at the L4-L5 level and need rehabilitation.
When I stretch my lower back, the affected leg becomes numb and feels almost devoid of sensation.
When I touch it with the other leg, I experience pain.
Is this normal? Additionally, after stretching, when I move my leg off the mat, I continue to feel the pain from the stretch.
I have to alternate by pulling my knees towards my chest to slightly relieve the pain before I can get out of bed.
Is this situation normal? I would appreciate your clarification!

Discomfort during lumbar traction may be due to posture issues or the inability of the lumbar and back muscles to withstand the pulling force.
In such cases, the severity of the discomfort should be assessed to determine the appropriate response.
For instance, if pain persists after the traction when the feet are moved off the platform, it is more likely that the lumbar and back muscles cannot handle the force.
If the discomfort is temporary and resolves after lumbar electrical therapy, it is advisable to slow down the rate of weight increase and strengthen the lumbar and back muscles at home.

If there is numbness in the legs to the point of reduced sensation, but it improves after moving the legs post-traction, it is likely not a serious issue.
In this case, trying a different traction machine or adjusting the posture during traction may help improve the situation.
However, if the discomfort is intolerable and prevents weight increase, it is recommended to undergo a lumbar CT scan to check for other issues or to consider it as a reference for potential surgical intervention.

When dealing with lumbar disc herniation, it is not uncommon to experience pain during lumbar traction, especially if the affected leg is experiencing numbness or tingling. This can be attributed to the fact that traction aims to relieve pressure on the spinal nerves and discs, but it can also temporarily exacerbate symptoms if the underlying condition is particularly sensitive or inflamed.

In your case, the pain and numbness in the affected leg during traction could indicate that the traction is either not effectively relieving the pressure on the nerve or that the nerve is still irritated. It is essential to understand that while some discomfort during traction can be expected, especially if the treatment is aggressive, significant pain or worsening symptoms should be communicated to your healthcare provider immediately.

The sensation of pain radiating down your leg during traction suggests that the nerve root may still be compressed or irritated. This is a common symptom associated with lumbar disc herniation, where the herniated disc material can impinge on the nerve roots exiting the spinal column. The fact that you feel pain when touching the affected leg with the other leg indicates that there is likely a neurological component to your symptoms, which could be due to inflammation or mechanical pressure on the nerve.

After traction, if you continue to experience pain when moving your leg off the traction table, this could be a sign that your body is still adjusting to the treatment or that the underlying issue has not yet been resolved. The need to pull your knees to your chest to alleviate pain suggests that flexing the lumbar spine may provide temporary relief, which is a common compensatory mechanism for individuals with lower back pain.

In terms of rehabilitation, it is crucial to work closely with your physical therapist or healthcare provider to ensure that the traction and other therapeutic modalities are tailored to your specific condition. They may need to adjust the intensity or duration of traction, incorporate other forms of therapy, or modify your rehabilitation program based on your response to treatment.

It is also important to consider other factors that may contribute to your symptoms. For instance, muscle imbalances, poor posture, or even psychological factors such as stress can exacerbate pain and discomfort in individuals with disc herniation. A comprehensive approach that includes strengthening exercises, flexibility training, and education on proper body mechanics can be beneficial.

If your symptoms persist or worsen, further diagnostic imaging, such as an MRI, may be warranted to assess the status of the herniated disc and any potential changes in the spinal canal or nerve roots. Additionally, if conservative management does not yield satisfactory results, discussing other treatment options, including injections or surgical interventions, may be necessary.

In summary, while some discomfort during lumbar traction can be normal, significant pain or persistent symptoms should not be ignored. Open communication with your healthcare provider is essential to ensure that your rehabilitation program is effective and safe. Adjustments to your treatment plan may be necessary based on your ongoing symptoms and response to therapy.
