Understanding Low Back Pain: A Physiotherapy Approach

Low back pain is very common and something most people experience at some point in their lives. For many people, back pain can feel frightening, frustrating, and limiting, understanding how back pain works can help you take control rather than feeling controlled by it.

How Common Is Low Back Pain?

Low back pain is one of the leading causes of disability worldwide, and up to 80% of people will experience it at least once. Most episodes improve with time, movement, and conservative care such as physiotherapy (Hartvigsen et al., 2018; Balagué et al., 2012).

Non-Specific Low Back Pain

Majority of the low back pain is described as non-specific, meaning it cannot be linked to a single structure or injury. This type of back pain is very common and responds well to movement, exercise and having some knowledge about managing back pain (Balagué et al., 2012).

In a small number of cases, back pain may be related to other conditions, such as nerve irritation (radiculopathy) or more serious medical causes. These situations are less common but important to recognise (Airaksinen et al., 2006).

When Should You Seek Help?

Most back pain does not require urgent treatment. However, you should seek professional advice if you experience:

• Pain that is severe, worsening, or not improving over time
• Pain that travels down the leg, especially with numbness, tingling, or weakness
• Difficulty walking or standing due to leg symptoms
• Pain following a significant fall or accident
• Unexplained weight loss, fever, or feeling generally unwell
• Changes in bowel or bladder function, or numbness around the groin area

A physiotherapist can assess your symptoms, provide reassurance, and refer you for further care if needed (Airaksinen et al., 2006).

Pain Does Not Equal Damage

Pain is not a direct measure of tissue damage. Modern pain science shows that pain is influenced by biological, psychological, and social factors, including nervous system sensitivity, emotions, beliefs, and past experiences (Balagué et al., 2012).

People can experience pain without ongoing tissue injury, and many structural changes do not cause pain at all. Pain is a protective response, not always an indicator of damage or harm.

Imaging Does Not Always Explain Symptoms

Scans such as X-rays or MRIs often show changes like disc bulges or “wear and tear.” These findings are very common in people without pain and do not always explain symptoms (Brinjikji et al., 2015).

Studies show that imaging findings often reflect normal age-related changes rather than the source of pain. For most cases of non-specific low back pain, imaging does not necessarily improve outcomes and is not routinely recommended unless red flag signs are present (Airaksinen et al., 2006).

Posture and Back Pain

There is no single “perfect” posture and no posture that automatically causes back pain. Sitting, standing, and lifting in different ways is normal and safe.

The spine is strong and adaptable. Prolonged time in any one posture — even an upright or “ideal” posture — can contribute to discomfort. Movement variability and regular position changes are more important than maintaining a “perfect” posture (Balagué et al., 2012).

Rest Is Not the Answer

While short periods of rest can help during a flare-up, long-term rest is not helpful for low back pain. Too much rest can lead to stiffness, loss of strength, and increased fear of movement (Airaksinen et al., 2006).

Keeping active within your comfort level helps recovery.

Movement and Exercise Help Long Term

Exercise therapy is one of the most effective treatments for chronic and recurrent low back pain (van Middelkoop et al., 2011). Movement improves strength, mobility, independence and confidence.

There is no single “best” exercise. The best program is one that is tailored to you, feels safe, and fits into your lifestyle.

Manual Therapy and Exercise

Hands-on treatments such as soft tissue massage or joint mobilisation can help reduce pain in the short term and make movement easier.

For long-term results, exercise and active self-management are key. Manual therapy works best when combined with movement and education (Airaksinen et al., 2006).

The Recurrent Nature of Low Back Pain and Taking Control of Your Back Pain

Low back pain often follows a recurrent pattern, with episodes that come and go (Hartvigsen et al., 2018). This recurrence does not mean the spine is damaged or deteriorating. Instead, it reflects the spine’s sensitivity to changes in activity levels, stress, sleep, workload, and overall health.

Understanding this recurrent nature helps shift the focus toward long-term independence with self-management rather than looking for a permanent fix.

Because low back pain can come and go, learning how to manage it yourself is important. Understanding your pain, staying active, independent, and knowing how to respond during flare-ups can reduce fear and improve confidence (Buchbinder et al., 2013).

Physiotherapy focuses on helping you move better, feel more confident, independent and stay active — not just treating pain, but empowering you to manage it long term.

Key Messages

• Most low back pain is non-specific and not serious
• Red flags and radiculopathy require appropriate assessment
• Pain does not always indicate tissue damage
• Imaging findings often do not correlate with symptoms
• There is no single “correct” posture
• Prolonged rest is not recommended
• Movement and exercise are essential for long-term recovery
• Education and self-management improve outcomes
