Osteoporosis/Osteopenia

Does lumbar osteoporosis always cause pain?

Lumbar osteoporosis does not usually cause pain until a fracture occurs. This condition weakens the bones in the lower back. It also affects other parts of the skeleton and primarily affects women after menopause, the period when menstruation ceases. ¹ However, pain can occur alongside osteoporosis. In such cases, a fracture, joint problem, or other cause should be investigated. Physical therapy can help improve mobility, strength, and certain types of pain, with treatments tailored to the fragility of the bones. It complements medical care aimed at preventing fractures.

What is lumbar osteoporosis?

Lumbar osteoporosis is a condition that weakens the vertebrae—the bones stacked in the lower back. The amount of bone mass decreases and the internal structure of the bone deteriorates, increasing the risk of fracture. ² Aging contributes to bone loss, but osteoporosis is not an inevitable consequence of aging. Hormonal factors, certain diseases, medications, and lifestyle habits can also play a role.

Osteopenia refers to bone density that is lower than normal but does not reach the threshold used to define osteoporosis. Bone density is the amount of minerals measured in the bone. ^{3, 1} Osteopenia does not necessarily lead to osteoporosis. Follow-up takes into account age, previous fractures, and other risk factors. Physical activity, diet, and appropriate treatments can help protect bone health.

A person can live with osteoporosis without experiencing pain or significant limitations. Back pain, therefore, does not distinguish between the two types of osteoporosis—painful and painless. Treatment should focus on identifying the cause of the pain and preventing fractures. Strength, balance, and a return to normal activities can improve, even though bone fragility requires long-term monitoring.

What are the symptoms of lumbar osteoporosis?

L’ostéoporose lombaire reste souvent silencieuse jusqu’à une fracture d’une vertèbre. Une telle fracture peut provoquer une douleur au dos, une perte de taille ou un dos plus courbé. Certaines fractures passent aussi inaperçues, comme le rappelle le guide britannique sur la prévention des fractures⁴. L’ostéoporose peut être découverte lors d’une mesure de densité osseuse ou après une fracture survenue lors d’une chute de faible hauteur.

Une douleur ou une raideur progressive du bas du dos peut avoir plusieurs causes; elle ne prouve pas que la perte osseuse fait mal. Le NIAMS, l’institut américain qui étudie notamment les maladies des os⁵, décrit l’ostéoporose comme une maladie habituellement silencieuse avant une fracture. Une douleur nouvelle, surtout après une chute ou un effort même léger, mérite une évaluation pour rechercher une fracture. Une raideur matinale ou une difficulté à bouger doit aussi être décrite au professionnel.

After ruling out a fracture or any other condition requiring specific treatment, your physical therapist may assess which movements increase or decrease associated lower back pain. The examples below describe possible reactions of the back. They do not constitute categories of osteoporosis and are not a substitute for a diagnosis.

Back pain worsens when the back rounds

For some people, positions that round the lower back can increase associated pain. Sitting for long periods, driving, or bending over to put on stockings, pants, or shoes can become uncomfortable. Describe these situations during the evaluation. Pain triggered by coughing or sneezing also warrants medical attention, especially if it is new.

Back pain worsens when the back arches

For some people, lower back pain worsens when the lower back arches. Walking or standing for long periods can become uncomfortable—for example, while grocery shopping, cooking, waiting in line, or attending a show. The effect of walking speed varies; it’s best to check with you rather than assume that walking faster will provide relief.

Lying on your stomach or on your back with your legs extended can also affect lower back pain. Reaching a high cabinet can be difficult. These reactions help in choosing comfortable positions, but they alone cannot identify the underlying cause.

The same person may experience pain both when the back rounds and when it arches. Your physical therapist uses these observations—along with your examination and your risk of fracture—to adapt the exercises. A tolerable movement alone does not rule out a fracture.

What are the serious symptoms to watch out for?

Significant weakness in the legs, loss of sensation around the genitals, or a new change in bladder or bowel control require urgent evaluation. Sudden, severe pain—or pain that worsens rapidly—also requires immediate medical attention. In cases of osteoporosis, new back pain following a fall or minor exertion should prompt an evaluation for a fracture.

Allez à l’urgence pour une faiblesse sévère, une paralysie ou une perte importante de sensibilité d’une ou des deux jambes. Une perte récente d’équilibre à la marche ou des gestes soudainement difficiles à coordonner doivent aussi être évalués rapidement. Avec un mal de dos, des douleurs, des picotements, une faiblesse ou un engourdissement dans les deux jambes demandent également une évaluation à l’urgence, selon les alertes du NHS, le service public de santé britannique⁶.

Go to the emergency room if back pain is accompanied by new difficulty urinating, involuntary leakage of urine or stool, or a loss of sensation around the genitals or anus. A new change in sensations during sex, erection, or orgasm also warrants this evaluation. Chest pain or back pain following a serious accident is also a warning sign. Call 911 if you need an ambulance.

Not all serious causes of lower back pain are equally common. In one review, a primary care study reported cauda equina syndrome—nerve compression in the lower back—in 0.08% of people seeking care for lower back pain. In another review, six primary care studies reported spinal cancer in 0 to 0.66% of people with back pain. These figures do not reflect the frequency of all warning signs or the risk of fracture in a person with osteoporosis. They do not justify delaying medical attention for the symptoms described.

Seek prompt medical attention if back pain is accompanied by a sensation of heat or cold, chills, or general malaise. Also seek medical attention for unintentional weight loss, a change in the shape of your back, pain that worsens at night, or pain that limits your activities. Emergency situations must be evaluated before any at-home advice is given. ^{7, 8}

What causes osteoporosis?

L’ostéoporose peut se développer lorsque la perte de tissu osseux dépasse sa reconstruction, notamment avec l’âge et certains changements hormonaux. Le risque augmente aussi avec des facteurs médicaux ou des habitudes de vie.¹ Après la ménopause, la diminution des estrogènes, des hormones qui contribuent à préserver l’os, favorise la perte osseuse.⁹ Le fait d’avoir 50 ans ne signifie pas qu’une mesure de densité osseuse est automatiquement nécessaire. Le choix du dépistage dépend de l’âge, des fractures antérieures et des autres risques, selon le guide d’Ostéoporose Canada¹⁰.

Physical activity and strength training can help maintain bone density. Strength and balance exercises also reduce the risk of falls among older adults living at home. Low body weight increases the risk of fractures. Certain medical conditions, including diabetes, can also affect bone health and the risk of falls. The assessment must take these factors into account. ^{11, 1213, 14}

An insufficient intake of calcium and vitamin D can be harmful to bone health. Calcium is a mineral found in bones; vitamin D helps the body absorb it. Smoking, heavy alcohol consumption, and certain medications—such as long-term use of corticosteroids—can also increase the risk. Corticosteroids are medications used primarily to treat inflammation. Do not stop taking them without consulting your prescribing healthcare provider. ^{15, 1416, 3}

How is osteoporosis diagnosed?

The doctor assesses osteoporosis based on your previous fractures, your risk factors, and, when necessary, a bone density test. Bone densitometry, also known as DXA, uses a low dose of X-rays to measure the mineral content in the bone, often at the hip and lower back. The result helps with the diagnosis, but two people with the same measurement may have different fracture risks. ^{3, 13}

The 2023 Osteoporosis Canada guidelines recommend this test starting at age 70 for individuals with no other risk factors, between ages 65 and 69 for those with at least one risk factor, or between ages 50 and 64 for those with a previous fracture or at least two risk factors. A history of fractures following minor trauma, repeated falls, low body weight, and certain medications are among the factors assessed. These guidelines pertain to risk assessment; pain that raises suspicion of a fracture requires an appropriate examination without waiting for routine screening.

Magnetic resonance imaging, or MRI, produces detailed images of tissues. In a study of 555 workers with recent back pain, early MRI without a clinical indication was associated with longer work disability and higher costs than no MRI. ¹⁷ This observational study does not prove that the test alone accounts for the entire difference. It does not justify delaying necessary imaging, particularly if a fracture or other serious condition is suspected.

An abnormality seen on an image is not necessarily the source of pain. In a study of people aged 55 to 80, the MRI findings alone were not sufficient to determine whether a narrowing of the spinal canal was causing the symptoms. ¹⁸ The spinal canal is the passageway that houses the nerve structures. This finding regarding stenosis—that is, narrowing—does not rule out the need to check for a fracture.

When should you consult a physiotherapist for lumbar osteoporosis?

You can consult a physical therapist to tailor your exercises, improve your balance, or resume activities despite having osteoporosis. Persistent pain or difficulty moving may also be reasons to seek an evaluation. Physical therapy for lower back pain can be helpful if you’re also experiencing back pain, while taking bone fragility into account. However, the warning signs described above require immediate medical attention, even before this consultation.

Au Québec, vous pouvez consulter directement un physiothérapeute en clinique privée sans prescription médicale, selon l’Ordre professionnel de la physiothérapie du Québec¹⁹. Le physiothérapeute peut vous orienter vers un médecin si l’examen soulève une autre cause ou une fracture possible. Le suivi médical de l’ostéoporose reste nécessaire pour évaluer les examens et les médicaments utiles.

What are the physiotherapy treatments for lumbar osteoporosis?

Physical therapy for osteoporosis primarily combines strength-building exercises, balance training, and advice on daily activities. If you’re experiencing pain, the physical therapist will investigate possible causes without assuming that osteoporosis is the source of the pain. The evaluation assesses your movement, strength, history of fractures, and risk of falling. Tests may also be conducted to determine whether nerves are contributing to the symptoms.

The physical therapist observes the positions you use and the movements that are difficult for you, such as standing up or carrying an object. He or she assesses your strength and balance. These observations are used to select exercises and adaptations that are appropriate for your activities, taking into account your comfort and abilities.

Des mobilisations articulaires, des mouvements lents réalisés avec les mains, peuvent parfois compléter les exercices pour un dos douloureux. Elles doivent être adaptées à l’examen et à la fragilité des os. Les manipulations lombaires avec une impulsion rapide sont à éviter en présence d’ostéoporose, selon les contre-indications de cette technique²⁰. Ces techniques rapides sont distinctes des gestes manuels doux.

Dans l’étude PROVE chez des personnes ayant une fracture d’une vertèbre liée à l’ostéoporose²¹, un programme de mobilisations lentes et d’étirements améliorait certains tests d’endurance du dos et d’équilibre à quatre mois, comparativement à une seule séance d’évaluation et de conseils. Le programme d’exercices apportait aussi des améliorations sur plusieurs mesures à quatre mois. À douze mois, aucun des deux programmes n’avait d’avantage clair sur les deux résultats principaux, la qualité de vie et l’endurance du dos. Le suivi permet de vérifier les bénéfices obtenus et d’ajuster les soins.

Your program may include core exercises, as well as leg and balance exercises. The difficulty level increases gradually based on your ability. Your physical therapist will also help you pace your activities, plan breaks, and adjust your usual postures. The goal is to make everyday movements easier and reduce the risk of falls.

The goal of osteoporosis treatment is to reduce the risk of fractures and maintain bone health. Some medications slow bone loss; others promote bone formation. Exercise, diet, and fall prevention complement this treatment. Associated pain may subside, although ongoing monitoring of bone fragility remains necessary.

What to do at home for lumbar osteoporosis?

At home, you can stay active, do the exercises you’ve chosen with your physical therapist, and adjust any movements that cause pain. First, have any new pain evaluated, as it could indicate a fracture. The following advice applies to a stable situation; it does not replace the care needed if you experience the warning signs described above. Avoid staying immobile or in bed for long periods of time, unless specifically instructed to do so by a healthcare provider.

If you are not very active, start with short, manageable walks and a suitable strength-training program. If you are already active, try to continue doing the activities you enjoy, making any necessary adjustments. Strength and muscle endurance exercises can improve strength and help maintain bone density. A review of studies in postmenopausal women found that several types of exercise have a beneficial effect on bone density. ²² These results do not mean that every exercise produces the same effect or heals a fracture.

If rounding the back increases the associated pain

If sitting for too long increases your pain, alternate positions and get up regularly to walk around a bit, as comfortable as you feel. There’s no need to try to find the perfect position.

When sitting, try using a backrest that supports your back without putting strain on it. A rolled-up towel placed across the lower back can improve comfort for some people. Keep only the adjustments that help you; changing positions is still helpful.

Marchez selon une durée confortable. La course peut rester possible pour certaines personnes, mais elle doit tenir compte des fractures antérieures, de l’équilibre et de votre expérience. Après une fracture vertébrale ou plusieurs fractures survenues après un faible traumatisme, le consensus britannique sur l’exercice et l’ostéoporose²³ recommande par prudence de limiter les impacts au niveau de la marche rapide, sauf avis individualisé. En voiture, ajustez le siège et le dossier pour atteindre les pédales sans vous étirer, tout en gardant une position de conduite sûre.

For recent back pain without a serious underlying cause, advice to stay active offers modest benefits in terms of pain relief and functional ability compared to bed rest. ²⁴ This review does not specify guidelines following a vertebral fracture. If a fracture is diagnosed, movement should be resumed according to the plan established with the healthcare team.

To bend over, try bending at the hips and knees while keeping the object close to you. A slow, controlled movement can make this easier. If you have osteoporosis, it’s best to avoid movements that cause your back to round significantly, especially if done repeatedly or while carrying a load. This doesn’t mean that all back movements are dangerous. Your physical therapist can show you a way to bend over that’s appropriate for your activities. To rest, try lying on your back or stomach only if it feels comfortable.

If arching your back increases the associated pain

If standing makes the pain worse, alternate between standing and sitting. You can also place one foot slightly in front of the other and gently shift your weight between your feet. Use a stable support if you’re unsteady on your feet. Only do this if it makes you more comfortable.

While cooking, resting one foot on a small, stable surface can make standing more comfortable. Avoid surfaces that are slippery or too high, and keep the counter within easy reach. When taking a break, try lying on your side with a pillow between your knees. Choose positions that provide relief without straining your back.

Seek medical attention if home care does not improve back pain that has already been evaluated after a few weeks—or sooner if the pain limits your activities or causes you concern. New pain, rapid worsening, or a warning sign should not be ignored for that long. Exercise should be adjusted or stopped if it worsens your symptoms.

How does lumbar osteoporosis progress?

Lumbar osteoporosis requires long-term monitoring to reduce the risk of fracture; the course of associated pain depends on its cause. Improvement in pain or functional ability is still possible with appropriate care. In a review of acute back pain, pain and functional limitations decreased by an average of 58% during the first month, with further improvement continuing for up to about three months. ²⁵ This result describes an average decrease in scores, not the proportion of people who were cured. It does not allow for predicting the time it takes for a fracture or pain to resolve in people with osteoporosis.

Physical activity, a diet rich in nutrients, and appropriate medical treatments help protect bones. Strength, balance, and home modifications can reduce the risk of falls. These measures remain beneficial after a diagnosis; they do not prevent fractures entirely.

Concerns about pain are also worth discussing. In a study of 406 people whose back pain had persisted for three months, more severe pain, greater functional limitations, and the belief that the pain would continue were associated with a slower recovery. ²⁶ This association does not prove that thoughts cause pain. Nor does it allow us to predict the progression of your osteoporosis.

What conditions may be associated with lumbar osteoporosis?

Lumbar osteoporosis may occur alongside back pain, osteoarthritis, or pain in the small joints of the back; it may also lead to a vertebral fracture. Lumbar osteoarthritis is a joint condition that primarily affects the cartilage—the smooth tissue that covers the surfaces of the bones. It is distinct from bone fragility. The changes seen on imaging studies do not always correspond to the pain experienced. ²⁷

Lumbar facet syndrome refers to pain attributed to the small joints at the back of the vertebrae. Certain movements, such as arching the back, can increase this pain. This reaction alone does not confirm the diagnosis and is not a specific sign of osteoporosis.

A lumbar vertebral fracture can occur in a weakened bone following a minor fall, physical exertion, or sometimes without any obvious trauma. Medical management of osteoporosis aims to reduce this risk and the risk of another fracture. Physical therapy helps maintain strength, balance, and daily activities, with tailored instructions if a fracture is present.

Low back pain simply refers to pain in the lower back. It can occur alongside osteoporosis without being caused by it. Treatment takes into account the pain, bone fragility, and the possibility of a fracture; therefore, it is not the same in every situation.

Why is exercise important in managing osteoporosis?

Exercise helps maintain bone density, strengthen muscles, and improve balance. In studies of postmenopausal women, exercise programs lasting at least six months had a beneficial effect on bone density in the lower back and hips. Activities that involve bearing your own body weight—such as walking, climbing stairs, or hiking—help you stay active. Exercises using weights, resistance bands, or your own body weight help build strength. The choice of exercises and the progression of your workout should be tailored to your ability and any previous fractures. ^{22, 11}

Balance training is important because a fall can lead to a fracture when bones are fragile. ²⁸ A review of 88 trials found that exercise reduced the frequency of falls by about 21% among older adults living at home, compared with control groups. ¹² Programs that focus on balance had greater effects. A reduction in falls does not automatically correspond to the same decrease in the number of fractures. You can practice balance near a stable support, following your physical therapist’s instructions.

The McKenzie approach can be used to identify movements that affect associated back pain. The movements are selected following an evaluation and tailored to the patient’s bone fragility. A favorable response to a movement does not prove that osteoporosis is the cause of the pain, nor does it prove that this approach is superior to others for treating bone disease.

In a review of spinal pain, centralization was observed in approximately 40% of the study participants. It means that pain felt farther away from the back—for example, in a leg—moves closer to the back with repeated movements. This phenomenon was associated with a more favorable outcome for back pain. ²⁹ It is distinct from simply adopting a comfortable position. The review did not demonstrate that this response enabled the selection of a more effective treatment, nor did it predict the progression of osteoporosis.

How can I get help for lumbar osteoporosis?

You can schedule an appointment with a physical therapist to tailor your exercises and activities to address lumbar osteoporosis. If you have back pain, the evaluation will identify the factors contributing to your symptoms and the situations that require medical attention. The treatment plan takes into account your goals, your abilities, and your risk of fracture.

You don’t have to wait for the pain to last for months before seeking help. An appointment can help clarify your options, but seeking care early doesn’t guarantee a faster recovery. If you experience any of the warning signs described in this article, seek the necessary medical care without waiting for a physical therapy session.
