Debunking the myth: why posture alone doesn't cause back pain - a physiotherapy perspective


In the realm of health and wellness, few topics are as pervasive as the link between posture and back pain.

We’ve all heard the adage, ‘sit up straight or you’ll hurt your back’, or ‘you’ve got a weak core that’s why your back hurts’.

While there’s certainly truth to the idea that maintaining good posture is beneficial for overall spinal health, and muscular strength is important, the notion that poor posture or muscle weakness directly causes back pain is overly simplistic and often misleading.

As a physiotherapist, I’ve seen countless patients with a variety of postural habits and corresponding back issues.

Equally I’ve seen people with terrible looking posture and muscle weakness with no history of back pain.

Through my experience as a physiotherapist, I aim to debunk this common myth and shed light on the multifaceted nature of back pain.

First and foremost, it’s crucial to recognise that back pain is a complex and multifactorial condition.

While poor posture can contribute to discomfort and strain in certain individuals, it’s rarely the sole culprit behind chronic or acute back pain.

Rather, back pain often stems from a combination of factors, including muscle weakness, joint dysfunction, poor movement patterns, structural abnormalities, and importantly psychological stressors.

Poor sleep coupled with increased life stressors can be key contributing factors to an awareness of back pain.

Furthermore, our bodies are remarkably adaptable and resilient.

They’re capable of withstanding a wide range of postures and movements without succumbing to pain or injury.

In fact, research has shown that the human spine is inherently robust and can tolerate significant variations in posture and loading.

It’s not so much the specific posture itself that’s problematic, but rather the prolonged or repetitive nature of certain postures, coupled with other contributing factors, that can increase the risk of developing back pain.

Moreover, our understanding of posture has evolved considerably in recent years.

Rather than prescribing rigid, one-size-fits-all guidelines for ‘ideal’ posture, modern physiotherapy emphasises dynamic movement and postural variability.

Instead of fixating on achieving a perfectly straight spine at all times, we encourage individuals to move frequently, change positions regularly, and engage in activities that promote strength, flexibility, and mobility.

While also being aware of their general well-being.

Additionally, it’s essential to address the underlying causes of poor posture rather than simply trying to correct it superficially.

This may involve identifying and addressing muscle imbalances, improving body awareness and proprioception, modifying ergonomic factors in the workplace or home environment, and implementing targeted exercises and stretches to improve overall spinal health.

Not to mention addressing psychological factors including poor sleep.

In conclusion, while maintaining good posture is undoubtedly important for spinal health, it’s not the sole determinant of back pain.

By adopting a holistic approach that addresses the complex interplay of biomechanical, physiological, and psychosocial factors, physiotherapists can help individuals manage and prevent back pain more effectively.

So, the next time you catch yourself slouching or hear someone warn against the perils of poor posture, remember that the story is far more nuanced than meets the eye.
