Paget’s disease of bone is a chronic disorder that disrupts the normal cycle of bone renewal, causing bones to become enlarged, weak and deformed. This condition typically affects older adults, with symptoms that can range from mild to severe. While the exact cause of Paget’s disease is unknown, genetic and environmental factors are believed to play a role.
Paget’s Disease of Bone
Paget’s disease of bone is named after Sir James Paget, who first described the condition in 1877. It primarily affects the pelvis, spine, skull, and long bones of the legs. In normal bone metabolism, old bone tissue is gradually replaced by new bone tissue. This process, known as bone remodeling, involves the balanced activities of two types of cells: osteoclasts (which break down old bone) and osteoblasts (which form new bone). In Paget’s disease, this balance is disrupted, leading to the formation of abnormal bone that is structurally weaker than normal bone.
Symptoms of Paget’s Disease
Symptoms of Paget’s disease can vary widely and some people may not experience any symptoms at all. When symptoms do occur, they may include:
- Bone pain, which can be persistent and severe
- Joint pain and stiffness
- Bone deformities, such as bowed legs or an enlarged skull
- Fractures, as weakened bones are more susceptible to breaking
- Hearing loss, if the disease affects the bones of the skull
- Nerve compression, leading to numbness, tingling, or weakness if the spine is involved
Diagnosis and Medical Management
Diagnosis of Paget’s disease typically involves a combination of medical history, physical examination, and diagnostic tests. Blood tests can reveal elevated levels of alkaline phosphatase, an enzyme linked to increased bone turnover. Imaging studies, such as X-rays, bone scans, and MRI, can help identify characteristic changes in bone structure.
Medical management of Paget’s disease aims to control symptoms and prevent complications. Treatment options may include:
- Medications: Bisphosphonates are the most commonly prescribed medications to slow down bone remodeling. Calcitonin, a hormone that helps regulate bone metabolism, may also be used.
- Pain Management: Over-the-counter pain relievers, such as acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs), can help manage pain. In severe cases, prescription pain medications may be necessary.
- Surgery: In cases of severe bone deformity, fractures, or joint damage, surgical intervention may be required to correct deformities or replace damaged joints.

The Role of Physiotherapy in Managing Paget’s Disease
Physiotherapy is an important component of the multidisciplinary approach to managing Paget’s disease. It focuses on improving mobility, reducing pain, enhancing strength, and maintaining overall quality of life. Here are key aspects of physiotherapy for individuals with Paget’s disease:
- Pain Management: Physiotherapists use various techniques to help manage pain associated with Paget’s disease. These may include:
- Heat and Cold Therapy: Applying heat or cold packs can help reduce pain and inflammation in affected areas.
- Transcutaneous Electrical Nerve Stimulation (TENS): TENS involves using electrical impulses to block pain signals and provide relief.
- Exercise Prescription: Exercise is crucial for maintaining bone health, improving muscle strength, and enhancing joint mobility. Physiotherapists develop individualized exercise programs tailored to each patient’s needs and abilities. Key exercises may include:
- Strength Training: Resistance exercises help strengthen muscles and support weakened bones.
- Flexibility Exercises: Stretching exercises improve joint flexibility and reduce stiffness.
- Aerobic Exercise: Low-impact activities such as walking, swimming, or cycling enhance cardiovascular fitness without putting excessive strain on bones and joints.
- Postural Education and Body Mechanics: Proper posture and body mechanics are essential for reducing stress on bones and joints. Physiotherapists teach patients how to maintain good posture during daily activities and provide guidance on safe lifting techniques to prevent injury.
- Balance and Coordination Training: Balance and coordination exercises help reduce the risk of falls and fractures, which are common complications of Paget’s disease. Physiotherapists may use exercises such as standing on one leg, heel-to-toe walking, and using balance boards to improve stability.
- Assistive Devices and Orthotics: In some cases, assistive devices such as canes, walkers, or orthotic inserts may be recommended to provide additional support and reduce strain on affected bones and joints.
- Patient Education: Educating patients about their condition and empowering them with self-management strategies is a key component of physiotherapy. Physiotherapists provide information on:
- The importance of regular exercise and physical activity
- Pain management techniques
- Strategies for maintaining a healthy weight to reduce stress on bones and joints
- Nutritional guidance, including the importance of calcium and vitamin D for bone health
- Home Exercise Program: Physiotherapists develop home exercise programs that patients can follow independently. These programs are tailored to the patient’s specific needs and abilities and are regularly updated to ensure continued progress.

Long-Term Management and Outcomes
Long-term management of Paget’s disease involves ongoing collaboration between the patient, physiotherapist, and other healthcare providers. Regular follow-up appointments with the physiotherapist help monitor progress, address any new symptoms, and adjust the treatment plan as needed. The goal is to maintain functional independence, minimize pain, and enhance overall quality of life.
With consistent physiotherapy and self-management strategies, many individuals with Paget’s disease can achieve significant improvements in symptoms and function. By staying active, maintaining a healthy lifestyle, and adhering to the prescribed exercise program, patients can effectively manage their condition and reduce the risk of complications.
Paget’s disease of bone is a complex condition that requires a comprehensive approach to management. Physiotherapy plays a vital role in addressing pain, improving mobility, enhancing strength, and promoting overall well-being for individuals with Paget’s disease. By tailoring interventions to each patient’s unique needs and empowering them with self-management strategies, physiotherapists help patients achieve better outcomes and maintain a higher quality of life. If you or a loved one has been diagnosed with Paget’s disease, consult with a physiotherapist or healthcare professional to develop a personalized treatment plan that addresses your specific needs and goals.
