Back pain can make everyday activities such as walking, sitting, bending, or working uncomfortable. Depending on the cause and symptoms, different physiotherapy approaches may be considered to help reduce pain and improve movement. Traction therapy for back pain is one technique that uses a controlled pulling force to gently separate or unload parts of the spine.
Traction is not suitable for every type of back pain, and research does not support its routine use for everyone with chronic low back pain. However, a physiotherapist may consider traction as part of an individualized treatment plan when a person’s symptoms and clinical assessment suggest it may be appropriate.
Traction therapy is a technique in which a controlled force is applied along the length of the spine. It can be delivered using a mechanical or motorized traction device, manual techniques, or other methods.
The goal is generally to reduce loading on certain spinal structures and, in some cases, temporarily relieve symptoms associated with spinal or nerve irritation.
Traction may be applied continuously or intermittently, depending on the technique and the individual’s condition. The amount of force, duration, and positioning should be determined based on the person’s symptoms and clinical assessment rather than using the same settings for everyone.
During traction, a controlled pulling force is applied to the spine. Depending on the technique used, this may create a temporary unloading effect on spinal structures.
The response to traction varies from person to person. For this reason, a physiotherapist should monitor symptoms and determine whether the technique is appropriate as part of a broader rehabilitation plan.
Traction is sometimes considered for people with back pain accompanied by symptoms that extend into the leg, such as certain forms of radicular or nerve-related pain.
Back pain can occur with or without leg symptoms. When a spinal nerve root is involved, a person may experience pain, tingling, numbness, or weakness extending into the leg.
A physiotherapist may assess factors such as:
Traction should therefore be viewed as a treatment option for selected patients rather than a universal solution for back pain.
The potential effects of traction depend on the person’s condition and the reason it is being considered.
Some patients may report:
However, these potential benefits should not be presented as guaranteed outcomes.
Current evidence does not show that traction provides meaningful benefits for everyone with chronic low back pain. The World Health Organization recommends against using traction as part of routine care for adults with chronic primary low back pain because the overall benefits are considered uncertain and potentially limited.
The effectiveness of traction depends on the type of back pain and the individual receiving treatment.
For chronic primary low back pain, the evidence does not support using traction routinely. WHO’s guideline gives a conditional recommendation against routine traction because the available evidence suggests that overall benefits are uncertain and may be small.
This does not necessarily mean that traction is inappropriate for every patient. Some people with specific presentations, particularly those involving leg symptoms or suspected nerve-root irritation, may be assessed differently.
The most appropriate approach is to identify the likely cause of the symptoms and choose treatment based on the individual’s clinical presentation rather than using traction simply because someone has back pain.
A traction session typically begins with an assessment of the person’s symptoms and movement.
Depending on the treatment approach, the process may include:
The physiotherapist reviews your symptoms, medical history, movement, strength, and neurological signs where appropriate.
You are positioned comfortably on the treatment table or equipment. The exact position depends on the technique and the area being treated.
The physiotherapist or traction device applies a controlled pulling force. The treatment may be intermittent or continuous.
Your symptoms are monitored during treatment. If pain, numbness, weakness, or other symptoms worsen, the technique may need to be stopped or modified.
When appropriate, traction may be combined with active physiotherapy approaches such as exercise, education, or movement-based rehabilitation.
This individualized approach is important because back pain can have many different causes and presentations.
Not everyone with back pain is a suitable candidate for traction.
An assessment may be particularly important when back pain is accompanied by:
The decision should be based on an individual’s assessment rather than the diagnosis alone.
Traction should not be performed without appropriate assessment when there are signs that the back pain may be related to a serious underlying condition.
Seek medical evaluation if back pain is associated with symptoms such as:
These symptoms may require medical investigation rather than routine physiotherapy treatment.
If symptoms become significantly worse during traction, treatment should also be stopped and reassessed.
Traction is only one possible component of back pain management.
Depending on the individual’s condition, a physiotherapy program may also include:
For chronic low back pain, WHO recommends approaches such as structured exercise and certain physical therapies rather than relying on traction as routine treatment.
The goal of physiotherapy is not simply to reduce pain temporarily. A broader rehabilitation program can also focus on improving movement, physical function, confidence, and the ability to return to everyday activities.
There is no single number of traction sessions that is appropriate for everyone.
The number and frequency of treatments depend on factors such as:
A physiotherapist should regularly reassess your progress and determine whether continuing traction is appropriate.
If the treatment does not improve your symptoms or causes them to worsen, the treatment plan may need to be changed.
Traction may be considered for selected patients, but it is not appropriate for every type of back pain. Evidence does not support its routine use for chronic primary low back pain.
Traction may be considered in some people with disc-related symptoms, particularly when leg or nerve-related symptoms are present. However, it should not be presented as a way to permanently push a herniated disc back into place. An individual assessment is needed to determine whether traction is appropriate.
Traction may be considered for some people experiencing back pain with leg symptoms, but it does not reliably relieve sciatica in everyone. The cause and pattern of the symptoms should be assessed before choosing treatment.
Traction should generally be comfortable or tolerable. However, some people may experience increased pain or other symptoms. If symptoms worsen during treatment, the technique should be stopped or reassessed.
Treatment duration varies depending on the type of traction, the individual’s condition, and the overall physiotherapy plan. A physiotherapist determines the appropriate duration and intensity rather than using one standard protocol for everyone.
There is no standard number of sessions. Your physiotherapist should assess your response and adjust the treatment plan according to your symptoms and progress.
Traction therapy for back pain uses a controlled pulling force to unload the spine and may be considered for certain patients, particularly when back pain is accompanied by specific leg or nerve-related symptoms. However, it is not a universal treatment for back pain, and current evidence does not support its routine use for chronic primary low back pain.
A thorough assessment is the best way to determine whether traction is appropriate for you. When needed, it can be considered alongside a broader physiotherapy program focused on improving movement, strength, function, and long-term management of back pain.
