Low back pain is one of the most common musculoskeletal complaints worldwide. While it is most often felt in the lower back, it can also radiate into the upper back, buttocks, and legs depending on the structures involved. Back pain related to lower limb mechanics develops gradually through postural and movement-related overload rather than sudden injury.
There are two broad categories of back pain, and understanding which applies is the starting point for effective treatment.
Specific Back Pain
Caused by an identifiable structural source — such as a disc prolapse, fracture, or pre-existing medical condition. Requires targeted investigation and often specialist management.
Non-Specific Back Pain
Caused by muscle strain, joint irritation, or nerve sensitisation without a clear structural cause. This is the category where foot mechanics and lower limb function play a significant role — and where podiatric assessment adds real value.
The foot is the foundation of the kinetic chain. How it contacts the ground directly influences the alignment of the ankle, knee, pelvis, and spine with every step. When foot mechanics are altered — through overpronation, leg length difference, or asymmetric gait — the effects are transmitted upward and can lead to cumulative strain on the lower back.
A common clinical example: if one foot pronates more than the other, that leg becomes functionally shorter, the knee rotates inward, and the pelvis on that side tips forward. This asymmetry alters spinal curvature during walking, bending and squatting — placing repetitive, abnormal stress on the muscles, ligaments and joints of the lower back.
When both feet are flat, both knees tend to collapse inward, the pelvis tilts forward, and the lumbar curve increases — a pattern that significantly increases compressive load on the lumbar spine over time.
Overpronation & Flat Feet
Excessive inward rolling of the foot alters leg rotation and pelvic alignment, increasing spinal load during walking and standing.
Leg Length Discrepancy
A functional or structural difference in leg length creates asymmetric pelvic tilt and spinal curvature — a persistent mechanical stress on the lower back.
Altered Gait Patterns
Poor timing, asymmetry or compensatory movement patterns during walking and running change how muscles and joints of the back are loaded with every stride.
Muscle Weakness & Imbalance
Weakness in the hip, gluteal or core stabilising muscles shifts load to the passive structures of the lower back — increasing strain under everyday demand.
Prolonged Standing or Walking
Occupations or activities requiring prolonged time on feet expose postural and mechanical inefficiencies that might otherwise be tolerated in shorter bouts of activity.
Footwear
Unsupportive footwear can exaggerate poor foot mechanics and increase the postural load transmitted to the lumbar spine during standing and movement.
Aching or pain in the lower back, particularly after prolonged standing or walking
Muscle tightness or stiffness across the lower back
Muscle spasm, especially after a period of activity or unaccustomed loading
Pain that is worse on one side, or alternates sides
Discomfort when bending, squatting, or rising from sitting
Pain that eases with rest but returns with activity
Our assessment begins with a detailed history of the pain — when it started, what makes it better or worse, and how it relates to activity and footwear. We then carry out a full biomechanical assessment from the ground up, evaluating how the foot, ankle, knee, hip and pelvis are functioning and interacting.
Detailed medical and pain history
Joint range of motion assessment — foot to pelvis
Muscle strength and flexibility testing
Movement analysis — walking, squatting, bending
Footwear and in-shoe assessment
Where low back pain has a mechanical or lower limb contributory factor, a podiatric approach can produce significant and lasting improvement. Treatment is tailored to your specific pattern of mechanics and symptoms.
Reduction in pain and frequency of flare-ups
Improved posture and movement patterns
Reduction in muscle tightness and spasm
Improved gait symmetry and efficiency
Greater understanding of your contributing factors
Tools to self-manage and prevent recurrence
01
Wear supportive footwear — avoid prolonged periods in flat, unsupportive shoes
02
Avoid prolonged static standing — shift weight, take breaks, use anti-fatigue matting where possible
03
Include regular hip, glute and core strengthening — these muscles protect the lower back
04
Complete your prescribed exercises and follow your orthotic plan consistently for lasting results
If your low back pain is recurring, related to activity, or worse after prolonged standing or walking, a biomechanical assessment is worth considering. Back pain driven by how you move and stand will not resolve without addressing those mechanics.
If you experience severe or sudden back pain, pain radiating down the leg, or any loss of bladder or bowel control, seek urgent medical attention. These symptoms require prompt assessment by a GP or specialist.
Why would a podiatrist treat low back pain?
Podiatrists are specialists in lower limb biomechanics. When back pain is driven by how the foot, ankle, knee and hip are functioning — rather than a spinal structural problem — addressing those mechanics through orthotics, gait retraining and rehabilitation can produce significant and lasting improvement.
Can flat feet cause back pain?
Yes. Overpronation and flat foot posture alter the rotation of the leg and the tilt of the pelvis during walking, which can place chronic, asymmetric stress on the lumbar spine. Correcting foot mechanics with orthotics is often an effective component of treatment.
Can a leg length difference cause back pain?
Yes. Even small leg length discrepancies create pelvic asymmetry and altered spinal loading. A simple heel lift or corrective orthotic can make a significant difference and is one of the most straightforward interventions we offer.
Do I need a scan?
For most non-specific back pain, no. Clinical assessment is sufficient. If there are signs of a specific structural cause — nerve compression, disc pathology, or red flag symptoms — we will refer promptly to the appropriate specialist.
How long does it take to see results?
Many patients notice improvement in pain and comfort within a few weeks of starting orthotics and rehabilitation. Longer-standing cases take more time, but consistent management of the underlying mechanics produces durable results that rest alone rarely achieves.
