Lumbar flattening and hyperlordosis treatment
The natural inward curve of the lower back (lordosis) varies from person to person. A reduced curve is called flattening, an increased one hyperlordosis. Neither is a disease in itself; the problem arises when the spine loses the ability to change and control that curve.
Also known as: Loss of lumbar lordosis, flat back, hyperlordosis, sway back
What is it?
The phrase 'flattening of the lumbar lordosis', common in X-ray reports, is usually not a permanent structural change but the result of muscle spasm at the moment of the scan. A painful back tightens the muscles around it protectively, and that tightening temporarily flattens the curve. Once pain settles, the curve mostly returns.
In hyperlordosis the picture is the opposite: the muscles at the front of the hip are shortened, the abdominals lengthened and the pelvis tipped forward. This posture places continuous pressure on the facet joints at the back of the spine. It is a common cause of low back pain that increases with prolonged standing.
What matters is not the degree of curve in a photograph but the person's capacity to change that curve during movement. Someone who locks the lower back while bending, or initiates every movement from the spine, overloads their segments regardless of curve. The programme therefore focuses on restoring movement control rather than teaching 'good posture'.
Symptoms
- Low back pain that increases with prolonged standing and eases on sitting (in hyperlordosis)
- Pain that increases with prolonged sitting and eases with movement (in flattening)
- A constant sense of tightness and fatigue in the lower back
- Difficulty initiating forward bending from the hip rather than the spine
- Stiffness noticeable in the morning that varies through the day
- Tightness at the front of the hip or early fatigue in the buttock muscles
Causes and risk factors
- Prolonged sitting, shortening the hip flexors and weakening the glutes
- Protective muscle spasm from pain — the most common cause of temporary flattening
- Lack of endurance in the deep trunk muscles
- Pregnancy and increased abdominal weight (in hyperlordosis)
- Footwear and prolonged standing at work
- Habitual movement patterning — initiating every movement from the lower back
The assessment
A posture photograph alone is not enough. How the curve changes in standing, sitting and lying is observed; if it varies with position there is no structural problem and the picture is fully correctable. Hip joint range, particularly the length of the hip flexors, is measured.
Movement control is then tested: during forward bending, squatting and single-leg standing, whether the movement is initiated from the spine or the hip is assessed. The measurements are shared with the patient, along with an explanation of what the angle on the X-ray means and why it is not by itself the treatment target.
Course of treatment
Weeks 0–2
Releasing tension
Shortened hip flexors and protective tension in the lower back muscles are reduced with soft tissue work and stretching. Where flattening is pain-driven, this stage alone often allows the curve to return on its own.
Weeks 2–6
Restoring hip movement
Full hip range is restored and forward bending is retrained to start from the hip rather than the spine. That single change markedly reduces the load the lower back is exposed to through the day.
Weeks 6–10
Combining control with load
The gluteal and deep trunk muscles are progressively strengthened. The aim is to maintain pelvic position during movement — dynamic control rather than a static posture.
Maintenance
Daily routine
Sitting setup, break rhythm and standing work positions are reorganised. A short but regular home programme lets the new movement pattern settle in.
How long does it take?
Where flattening is pain-driven, relief is usually clear within two to four weeks. If restricted hip range and muscle imbalance are present, the programme extends to 10–12 sessions. Changing the angle on the X-ray is not the goal; the goal is resolving pain and freeing movement — and both usually happen without the angle changing.
When to see a doctor
The findings below fall outside the scope of physiotherapy and require medical assessment.
- Postural change that progresses rapidly over a short period
- Progressive weakness or numbness in the legs
- Any change in bladder or bowel control
- Pain that is not relieved by rest at night and steadily increases
- Rapidly developing spinal curvature in childhood or adolescence
Frequently asked questions
The X-ray reports flattening — is this permanent?
Usually not. On an X-ray taken during a painful episode, muscle spasm flattens the curve, and it returns once the pain settles. Whether the curve changes with position is easily established on examination.
Is it advisable to constantly hold myself upright?
No. Trying to hold one position constantly fatigues the muscles and usually increases pain. What is healthy is being able to change position, and the programme aims to restore that flexibility.
Is it advisable to wear a brace?
Short-term use during a very painful episode can bring relief. Long-term use weakens the trunk muscles and creates dependence. The decision is based on duration, and a brace never replaces exercise.
Do abdominal exercises correct the curve?
Traditional sit-ups usually do more harm than good, repeatedly flexing the spine and increasing irritation. What works is controlled stabilisation work that teaches you to hold the pelvis steady.
