How can gait analysis help with lower back pain?
Lower back pain is complex and can be influenced by physical, psychological and lifestyle factors. In many cases, there is no single identifiable structural cause.
Although gait analysis cannot diagnose every cause of back pain, it can help assess whether walking mechanics, mobility restrictions or movement adaptations are relevant to an individual's symptoms.
Pelvic movement and trunk control
During walking, the pelvis and trunk naturally rotate and move in three dimensions. This movement is a normal part of efficient gait.
Some people with back pain develop a more guarded walking pattern, with reduced trunk rotation, shorter steps or an altered walking speed.
Gait analysis may help identify these adaptations and determine whether they are associated with pain, reduced confidence or limited mobility.
Treatment may include graded walking, trunk and hip strengthening, mobility exercises and gradual exposure to activities that have become difficult.
Hip mobility and lower back discomfort
Restricted hip movement can influence how a person moves during walking and other activities. For example, limited hip extension may lead to changes in pelvic or trunk movement.
Assessing hip mobility alongside gait can help determine whether a restriction is clinically relevant and whether improving hip mobility or strength might form part of the treatment plan.
However, restricted hip movement does not automatically cause back pain, and many people with back pain have no significant gait abnormality.
Walking-related back pain
Some people experience back pain that worsens after walking for a particular distance or period of time.
Observing walking posture, stride characteristics and symptom responses can provide useful information about functional limitations. In selected cases, this may help guide changes to walking tolerance, pacing and exercise progression.
Back pain accompanied by new bladder or bowel dysfunction, numbness around the saddle area or progressive leg weakness requires urgent medical assessment rather than a routine gait analysis.
Why is it important to assess the whole lower limb?
One of the biggest advantages of biomechanical gait analysis is that it considers the relationship between different parts of the body.
For example, a person with knee pain may also have reduced ankle mobility, weakness around the hip or a recent increase in running volume. Looking only at the knee could overlook other relevant factors.
Similarly, someone with back pain may have reduced hip mobility, but this does not mean that their foot posture is responsible for their symptoms.
A whole-body assessment helps establish which findings are most relevant to the individual and which are simply normal variations in movement.
It is also important to understand that a movement pattern that looks unusual is not necessarily harmful. Many people have different walking patterns without experiencing pain. The objective is to identify modifiable factors that matter to the person's symptoms and goals, not to force everyone into an identical pattern.
