Have you ever thought about running again after your back injury — sooner than you expected?

If you’ve experienced disc-related low back pain, the idea of running again can feel unrealistic — or even unsafe. Many people are told to “rest” or avoid impact altogether, which can lead to deconditioning, reduced aerobic fitness, and growing fear around movement.

At SportsFit Health and Rehab in Five Dock, we take a structured, progressive approach to returning to activity. With the help of an anti-gravity treadmill, we help patients maintain fitness, rebuild confidence, and gradually reintroduce walking or running — all while reducing load through the spine.

Why walking or running may feel hard with discogenic low back pain

One of the biggest challenges with discogenic low back pain is that everyday movements — especially walking or running — naturally increase load through the spine.

When you walk or run, your lumbar discs experience repeated axial loading and compression. For an irritated or sensitized disc, even normal levels of force can feel uncomfortable or provoke symptoms. Impact, speed, or longer durations can further increase this load, which is why many people notice soreness during or after activity.

Another factor is intra-abdominal pressure. Activities that require trunk stability — including jogging, faster walking, or uphill movement — often increase pressure within the abdomen to help stabilize the spine. While this is a normal and protective mechanism, some individuals with discogenic pain may perceive this pressure as stiffness or an increase in discomfort.

Because of these factors, people often feel like they can’t progress beyond gentle walking — not necessarily because movement is harmful, but because the load feels too high too soon. This is where graded unloading can play an important role.

For active individuals, losing cardiovascular fitness can be just as frustrating as the injury itself.

What is an anti-gravity treadmill?

An anti-gravity treadmill uses air pressure technology to reduce your effective body weight while walking or running. This allows you to move with a normal gait pattern while placing less load through your spine and lower limbs.

Instead of stopping activity altogether, we can modify the load — allowing earlier movement while symptoms settle.

Key benefits for discogenic low back pain

1. Maintain aerobic fitness while you can’t run normally

One of the biggest advantages is maintaining cardiovascular conditioning. By reducing body weight, many patients can walk or jog earlier without symptom flare-ups, helping minimise the drop in fitness during recovery.

2. Reduced spinal compression

By unloading a percentage of body weight, the forces travelling through the lumbar discs are reduced. This allows patients to reintroduce movement earlier while keeping symptoms manageable.

3. Maintain natural movement patterns

Unlike pool running or heavily modified drills, the treadmill allows you to walk or run naturally. This helps retrain coordination and running mechanics while still protecting the back.

4. Gradual exposure to load

Rehabilitation works best when load is increased progressively. The treadmill allows precise adjustments — for example:

• Starting at 50–70% body weight

• Progressing towards full weight bearing

• Gradually increasing speed or duration

This creates a controlled bridge between rehab exercises and full return to sport or running.

Beyond unloading: working on spinal position and lumbopelvic control

Reducing load is only one part of the process. During running rehab, we may also work on spinal positioning, trunk control, and lumbopelvic mechanics to help reduce excessive stress through the lower back.

This can include:

• Improving awareness of spinal posture during gait

• Developing better control through the hips and pelvis

• Building strength and endurance in the surrounding musculature

• Adjusting running mechanics where appropriate

The goal isn’t to create a “perfect” running style, but to help you move more efficiently and potentially reduce future overload of the lumbar spine.

When might we use it in rehab?

Every injury is different, but for some cases of discogenic low back pain, we may introduce anti-gravity treadmill sessions from around 1 week post-injury through to roughly the 3-week mark, depending on symptoms and clinical assessment.

During this early phase, the aim is often to:

• Keep you moving safely

• Maintain aerobic fitness

• Gradually expose the spine to controlled loading

At SportsFit Health and Rehab, treadmill sessions are always integrated alongside physiotherapy treatment, strength work, and movement retraining — not as a standalone fix, but as part of a broader rehab plan.

Thinking about running again after your back injury?

If you’ve been told to avoid impact forever, it might be worth revisiting what’s possible. With the right guidance and tools, many people with discogenic low back pain can safely return to higher levels of activity — while maintaining fitness along the way.

If you’re curious about whether an anti-gravity treadmill session could help your rehab journey, our team at SportsFit Health and Rehab in Five Dock can assess your situation and help you build a personalized plan.
