Frozen shoulder, medically known as adhesive capsulitis, is characterised by stiffness, pain, and a limited range of motion in the shoulder joint. While it can occur for various reasons, it is also closely associated with Parkinson’s disease, a neurodegenerative disorder that affects movement and causes rigidity, tremors, and bradykinesia (slowness of movement). Understanding how Parkinson’s disease can lead to a frozen shoulder and how to manage both conditions is essential for improving the quality of life for those affected.

The Connection Between Parkinson’s Disease and Frozen Shoulder
Parkinson’s disease primarily affects the brain’s ability to control voluntary muscle movements, leading to the characteristic tremors and rigidity that patients experience. Over time, as the disease progresses, individuals with Parkinson’s can develop muscle stiffness and reduced mobility in various parts of the body, including the shoulders. This connection between a frozen shoulder Parkinson’s highlights how restricted movement can lead to a condition where the shoulder joint becomes stiff, making it difficult for individuals to move their arms or perform routine activities.
The exact cause of frozen shoulder in Parkinson’s patients is not entirely understood. Still, it is believed to be related to a combination of muscle rigidity, immobility, and inflammation in the joint capsule. Parkinson’s disease itself leads to reduced muscle activity and lack of movement, which can result in the tightening of the connective tissues around the shoulder. As these tissues thicken and become inflamed, the shoulder joint becomes progressively stiffer, leading to a restricted range of motion.
Symptoms of Frozen Shoulder in Parkinson’s Disease
The symptoms of frozen shoulder in Parkinson’s patients can be similar to those experienced by individuals without the disease, though the underlying causes are different. Initially, individuals may experience pain in the shoulder, particularly when trying to move the arm. Over time, the pain may subside, but the stiffness and limited range of motion will continue. Patients with Parkinson’s disease may find it particularly challenging to raise their arms, reach behind their backs, or carry out everyday tasks like dressing or reaching for objects on high shelves.
Due to the nature of Parkinson’s disease, the muscles around the shoulder may already be weakened, which can exacerbate the symptoms of a frozen shoulder. For instance, while one might expect pain and stiffness in the shoulder joint, individuals with Parkinson’s may also experience generalised muscle weakness and rigidity in surrounding areas, such as the neck, upper back, and arms, which can make managing both conditions even more difficult.
Managing Frozen Shoulder in Parkinson’s Disease
Effective management of frozen shoulder in Parkinson’s patients requires a comprehensive approach, often involving physical therapy, medications, and in some cases, surgical intervention. Since Parkinson’s disease already compromises mobility, addressing a frozen shoulder early is important to avoid further physical limitations.
Physical Therapy and Exercise
Physical therapy is a cornerstone of managing a frozen shoulder, and it is essential for those with Parkinson’s disease. A physical therapist can design a programme that helps improve shoulder mobility and relieve stiffness. Specific exercises aimed at gently stretching the shoulder joint can help break down the scar tissue that contributes to the tightness. These exercises should be done progressively, starting with gentle stretches and gradually increasing in intensity to avoid further strain or injury.
Additionally, regular movement and stretching of the shoulders are crucial for preventing the condition from worsening. Patients should be encouraged to maintain daily physical activity, even if it is light, as this can improve overall mobility and prevent the shoulder from becoming further stiffened.
Medications
Pain management is another important aspect of treating a frozen shoulder. Over-the-counter pain relievers, such as ibuprofen or paracetamol, can help manage discomfort. In cases where pain is more severe, a doctor may recommend stronger prescription medications or corticosteroid injections to reduce inflammation and provide temporary relief.
For patients with Parkinson’s disease, the medications used to treat the condition, such as levodopa, may indirectly affect the progression of a frozen shoulder. These medications work by improving muscle control and reducing rigidity, which may make physical therapy exercises more effective.
Surgical Treatment
In some cases, conservative treatments such as physical therapy and medication may not be enough to provide relief. If the pain and stiffness persist or significantly impair function, surgical intervention may be considered. Options include shoulder arthroscopy, which involves using a small camera to remove scar tissue and release the tight joint capsule, or shoulder manipulation under anaesthesia, which forces the shoulder to move to break up adhesions and restore movement.
However, surgery should only be considered after all non-invasive treatments have been exhausted, and the potential risks are carefully weighed, particularly in Parkinson’s patients who may have other complicating health issues.
Preventive Measures and Lifestyle Adjustments
Preventing frozen shoulders in individuals with Parkinson’s disease can be challenging due to the nature of the disorder itself. However, several strategies can help minimise the risk of developing this condition or prevent it from worsening:
- Maintaining Regular Movement: Even if full shoulder mobility is not possible, engaging in light exercises and stretching can help prevent stiffness. Simple movements such as shoulder rolls or arm swings may help keep the joint flexible.
- Managing Parkinson’s Symptoms: Effectively managing Parkinson’s disease through medication and therapy can help reduce the severity of muscle rigidity, making it less likely for a frozen shoulder to develop. Working closely with a healthcare provider to optimise Parkinson’s treatment is vital.
- Heat and Cold Therapy: Applying heat or cold packs to the affected shoulder may help alleviate pain and inflammation. Heat can relax the muscles and improve blood flow, while cold therapy can reduce swelling.
- Adapting Daily Activities: Patients should modify daily activities to avoid putting excessive strain on the shoulder. This can include using assistive devices, such as grab bars in the bathroom, to reduce the need for reaching or lifting heavy objects.
Conclusion
A frozen shoulder is a common complication for individuals with Parkinson’s disease, primarily due to the muscle rigidity and reduced movement associated with the condition. Managing frozen shoulder in Parkinson’s patients involves a multifaceted approach, including physical therapy, medication, and sometimes surgical intervention. With early intervention, regular exercise, and proper medical management, patients can maintain a good quality of life and manage both conditions effectively.
