Acromioclavicular Joint Dysfunction (AC)

Acromioclavicular Joint Dysfunction Acromioclavicular (AC) affects the acromioclavicular joint where the collarbone (clavicle) meets the shoulder blade (scapula). This joint, is vital in allowing the shoulder to move freely. When injured or dysfunctional, it is painful and causes restricted movement in the shoulder area and arm. AC joint dysfunction is most commonly associated with injury, overuse, or degeneration, but it can also result from poor posture or imbalances in surrounding muscles.

If you’re experiencing shoulder pain, particularly near the top of your shoulder or with overhead movements, it’s important to consult with a healthcare professional for a proper diagnosis. With the right treatment, acromioclavicular joint dysfunction can often be managed effectively, helping you return to your normal activities without pain.
Causes

There are a few common causes of AC joint dysfunction. One of the most frequent is a traumatic injury, such as a fall onto the shoulder or a direct blow to the area. This can cause damage to the ligaments or the joint itself. Overuse, especially in activities that involve repetitive overhead motions like swimming, weightlifting, or throwing sports, can also lead to strain on the AC joint.

Symptoms

Symptoms of AC Joint Dysfunction vary depending on the severity of the condition. People often experience pain on the top of the shoulder, particularly when lifting the arm overhead or performing actions like reaching or throwing. The pain can be sharp or aching, and it may worsen with certain movements or after physical activity. In some cases, swelling or tenderness may be present around the joint. In some cases, aging or wear and tear can contribute to joint degeneration and dysfunction.

Treatment

Treatment goals for AC Joint Dysfunction are to relieve pain, reduce inflammation, and restore normal function. Non-surgical options are available at Abacus Chinese Medicine. We use an individualized integrated approach, choosing from  a range of manual medicine methods to meet your needs. Each modality can be used individually or in combination. Among these methods are:

• Manual Manipulation: Gentle manual manipulation is effective in restoring joint mechanics and reducing pain.
• Muscle Energy Technique (MET): Engages restricted muscles to improve joint mobility.
• Strain-Counterstrain: Relieves pain by positioning the joint in a relaxed posture to reset neuromuscular reflexes.
• Acupuncture: Reduces inflammation, improves blood flow, and modulates pain.
• Craniosacral Therapy (CST): Restore fluid balance and reduce fascial restrictions affecting the AC joint. Gentle techniques release tension in the clavicular fascia, sternoclavicular joint, and surrounding soft tissues, promoting better alignment and pain relief.
