Is It Normal to Hear Clicking Sounds During Frozen Shoulder Exercises? - Rehabilitation

Hearing clicking or popping sounds during shoulder exercises, especially in the context of frozen shoulder (adhesive capsulitis), is a common experience and can be attributed to several factors. When your mother performs exercises like wall climbing or towel stretches, the sounds she hears may be due to the movement of tendons, ligaments, or the joint itself.
Frozen shoulder is characterized by stiffness and pain in the shoulder joint, which can lead to changes in the way the shoulder moves. As the shoulder joint becomes less mobile, the surrounding tissues may become tight and may not glide smoothly over one another. This can result in audible sounds during movement. Here are a few reasons why these sounds might occur:
1. Tendon Movement: As muscles and tendons move over bony structures, they can create a snapping or clicking sound. This is often harmless and is known as "crepitus." It can occur when the tendons or ligaments snap over the bones or other structures in the shoulder.

2. Joint Cavitation: The shoulder joint contains synovial fluid, which helps lubricate the joint. When the joint is moved, gas bubbles in the synovial fluid can form and collapse, creating a popping sound. This phenomenon is similar to the sounds heard when cracking knuckles.

3. Scar Tissue: In cases of frozen shoulder, the formation of scar tissue can restrict normal movement. As the shoulder is exercised and the scar tissue is stretched or moved, it may produce sounds as the tissues shift.

4. Joint Alignment: If the shoulder joint is not properly aligned due to the stiffness associated with frozen shoulder, movements may cause the bones to rub against each other or against the cartilage, leading to clicking sounds.

While these sounds can be concerning, they are often not indicative of any serious underlying issue, especially if there is no accompanying pain or discomfort. However, it is essential to monitor the situation. If your mother experiences increased pain, swelling, or a decrease in her range of motion, it would be advisable to consult her healthcare provider or physical therapist for further evaluation.

In terms of managing her frozen shoulder, it is crucial to continue with the prescribed exercises, as they are designed to improve mobility and reduce stiffness. Here are some additional tips to consider:
- Warm-Up: Ensure she warms up her shoulder before starting exercises. Gentle heat can help relax the muscles and improve blood flow.

- Gradual Progression: Encourage her to progress gradually with her exercises. If she feels pain, she should not push through it, as this could exacerbate her condition.

- Physical Therapy: Regular sessions with a physical therapist can provide tailored exercises and manual therapy techniques that may help alleviate symptoms and improve function.

- Pain Management: If she experiences discomfort, over-the-counter pain relievers may help, but she should consult her doctor before starting any medication.

- Follow-Up: Regular follow-ups with her healthcare provider can help monitor her progress and make any necessary adjustments to her treatment plan.

In conclusion, hearing clicking sounds during frozen shoulder exercises is generally normal and can be attributed to various benign factors related to joint and tissue movement. However, it is essential to remain vigilant for any changes in symptoms and to maintain open communication with her healthcare team.
