Osteoporosis
Bone health, fracture prevention and physiotherapy rehabilitation
Introduction
Osteoporosis is a condition in which bone mass and bone quality are reduced, making bones more fragile and increasing fracture risk. It can remain silent for a long time because a person may feel completely well until a fragility fracture occurs. The spine, hip and wrist are important sites of osteoporotic fracture.
Physiotherapy has an important role in maintaining physical capacity, improving muscle strength, balance and posture, reducing fall risk and teaching safe movement. The goal is not to make a person afraid of movement. Instead, the goal is to create the safest effective level of loading for the individual's fracture risk and functional needs.
| Core rehabilitation idea A patient with osteoporosis needs safe, progressive physical loading—not complete inactivity. Exercise selection must be adapted to fracture history, bone health, symptoms and medical guidance. |

Bone Remodeling and Pathophysiology
Healthy bone is continuously remodeled. Old bone is removed and new bone is formed. Osteoporosis develops when the balance shifts toward net bone loss and the internal structure of bone becomes less able to tolerate normal mechanical stress.
Reduced bone mass and changes in bone microarchitecture can increase fragility. This is why fall prevention is so important: a fall can turn an underlying fracture risk into an actual fracture.
Types of Osteoporosis
| Type | General description | Clinical consideration |
|---|---|---|
| Primary type I | Often associated with postmenopausal estrogen deficiency. | Fracture prevention and safe strengthening are important. |
| Primary type II | Associated with aging and age-related changes in bone remodeling. | Consider strength, balance, mobility and fall risk. |
| Secondary osteoporosis | Related to diseases, medications or other risk factors. | Medical history and contributing condition should be reviewed. |
Risk Factors
Risk factors can include older age, postmenopausal hormonal changes, low physical activity, low mechanical loading, nutritional problems and certain medical conditions or medications. Long-term corticosteroid exposure, hyperthyroidism and chronic kidney disease are examples of factors that can contribute to secondary bone loss.
- Older age.
- Ostmenopausal hormonal changes.
- Ow physical activity.
- Reduced weight-bearing activity.
- Long-term corticosteroid exposure.
- Certain endocrine or metabolic disorders.
- Chronic kidney disease and associated metabolic problems.
- Inadequate nutrition or other lifestyle risk factors.
Clinical Presentation
Osteoporosis is often asymptomatic until a fracture occurs. Vertebral fractures may cause back pain, loss of height and changes in posture. Repeated vertebral collapse can contribute to increased thoracic kyphosis and difficulty with daily activities.
A person can therefore have significant fracture risk without having pain. This makes prevention, medical review and functional assessment important when risk factors are present.
| Clinical pearl Do not wait for pain before considering bone health. A person may feel normal while still having reduced bone strength. |

Assessment and Diagnosis
Assessment should begin with fracture history, falls, medical history, medication exposure and current functional level. Physiotherapy also examines posture, strength, balance, gait and the ability to perform daily activities safely.
| Assessment area | Examples | Purpose |
|---|---|---|
| Fracture history | Previous wrist, hip or vertebral fragility fracture | Helps estimate functional and exercise precautions. |
| Falls | Previous falls, near-falls and environmental risks | Identifies preventable fracture risk. |
| Posture | Spinal alignment and kyphosis | Guides movement and postural education. |
| Strength | Lower limb, trunk and upper limb capacity | Supports independence and fall prevention. |
| Balance | Static and dynamic balance | Identifies instability and confidence problems. |
| Medical context | Medications and conditions affecting bone health | Helps tailor the program and referral needs. |
DXA and Bone Mineral Density
DXA is a commonly used method for measuring bone mineral density. T-scores are used in diagnostic classification. Physiotherapists should understand that the DXA result is only one part of the clinical picture; fracture history, age, falls, function and medical context also influence rehabilitation decisions.
Physiotherapy Management
Exercise is an important part of osteoporosis management, but the program should be individualized. The clinician should consider fracture history, current symptoms, severity of bone loss, age, functional ability and medical advice.
1. Weight-Bearing Activity
Appropriate weight-bearing activity provides mechanical stimulus to bone and supports general mobility. Examples may include walking and other safe upright activities, depending on the patient's status. The activity should be matched to fracture risk rather than selected simply because it is weight-bearing.
2. Progressive Resistance Training
Resistance training improves muscle strength and functional capacity. Stronger muscles support daily activities and may reduce fall risk. Progression should be controlled, with technique and safety prioritized over maximal loads.
3. Balance and Fall Prevention
Balance training is central because preventing a fall can reduce fracture risk. Training may include supported standing, stepping, transfers, gait challenges and gradually more demanding balance tasks.
4. Posture and Safe Movement
Patients can be taught safer strategies for transfers, lifting and daily activities. Individuals with vertebral fractures or high fracture risk require particular care with spinal loading and exercise selection.
| Rehabilitation component | Main purpose |
|---|---|
| Resistance exercise | Improve muscle strength and functional capacity. |
| Weight-bearing activity | Provide appropriate mechanical stimulus and support mobility. |
| Balance training | Reduce fall risk and improve confidence. |
| Postural education | Support safer movement strategies. |
| Functional training | Improve independence in everyday tasks. |
Exercise Progression Principles
The exact exercises depend on the individual. A person who is very inactive may begin with supported strengthening and balance tasks. As capacity improves, resistance, repetitions, standing time, walking distance and task complexity can be increased. The aim is consistent progression without unsafe loading.
- Begin at a safe and manageable level.
- Prioritize technique and controlled movement.
- Progress resistance gradually.
- Train balance in a safe environment with appropriate support.
- Practice transfers and functional tasks.
- Increase walking and daily activity according to capacity.
- Consider fracture history when selecting spinal loading and impact activities.
| Precaution Recent fracture, vertebral fracture, severe osteoporosis, significant pain or other medical concerns may require modified loading and medical guidance before progression. |

Educational Clinical Case Study
A 67-year-old woman with known osteoporosis has become afraid of walking outdoors after a previous wrist fracture from a fall. She is physically inactive and reports low confidence on uneven surfaces.
Assessment identifies reduced lower-limb strength, impaired balance and fear during outdoor walking. The physiotherapist reviews the fracture history and medical status before progressing exercise.
Management begins with safe resistance exercise, supported balance practice, walking and education about environmental fall risks. As strength and confidence improve, balance tasks become more challenging and walking is gradually extended. The program focuses on safe progressive capacity rather than maximal loading.
Patient Education and Fracture Prevention
- Continue appropriate medical management and follow the healthcare team's advice.
- Stay physically active at a safe level.
- Improve strength and balance consistently.
- Reduce home hazards such as loose rugs or poor lighting.
- Use appropriate footwear and mobility aids when prescribed.
- Do not allow fear of fracture to result in complete inactivity.
- Discuss nutrition and bone-health needs with the appropriate healthcare professional.
Frequently Asked Questions
Can osteoporosis exist without pain?
Yes. Osteoporosis can be silent until a fracture occurs.
What are common osteoporotic fracture sites?
The vertebrae, hip and wrist are important common sites.
Can a person with osteoporosis exercise?
Yes. Appropriate exercise is an important part of management, but the program must match fracture risk and clinical status.
Why is balance training important?
Better balance can reduce the chance of falling, and preventing falls can reduce fracture risk.
What is DXA?
DXA is a method used to measure bone mineral density and is commonly used in osteoporosis evaluation.
