Unable to Abduct Shoulder Past 90 Degrees: Causes, Treatment, and Prevention

Nov 1, 2023

Welcome to IAOM-US, your trusted source for expert advice and services in Health & Medical, Chiropractors, and Physical Therapy. In this article, we will explore the causes, treatment options, and prevention tips for a limited range of motion in the shoulder joint, specifically the inability to abduct the shoulder past 90 degrees.

Understanding the Shoulder Joint

The shoulder joint is one of the most dynamic and complex joints in the human body. It allows for a wide range of movements, including abduction, adduction, flexion, extension, rotation, and circumduction. However, when the shoulder's range of motion is limited, it can greatly impact one's daily activities and overall quality of life.

Causes of Inability to Abduct Shoulder Past 90 Degrees

There are several potential causes for the inability to abduct the shoulder past 90 degrees. It is essential to identify the underlying factors to develop an effective treatment plan. Here are some common causes:

Anatomical Abnormalities

Structural abnormalities, such as an acromioclavicular (AC) joint injury, rotator cuff tear, or frozen shoulder, can restrict the shoulder's range of motion. These conditions may result from trauma, repetitive stress, or age-related degeneration.

Muscle Imbalances and Weakness

Imbalances in the muscles surrounding the shoulder joint, particularly the rotator cuff muscles, can lead to limited abduction. Weakness in these muscles can affect stability, resulting in decreased mobility and increased risk of injuries.

Postural Issues

Poor posture, such as rounded shoulders or a forward head position, can impact the alignment of the shoulder joint. Over time, these postural issues can contribute to a limited range of motion, especially in abduction.

Adhesive Capsulitis (Frozen Shoulder)

Frozen shoulder is a condition characterized by the gradual loss of shoulder mobility, including abduction. It involves the thickening and tightening of the capsule surrounding the shoulder joint, resulting in stiffness and pain.

Treatment Options for Limited Shoulder Abduction

When faced with the inability to abduct the shoulder past 90 degrees, there are various treatment options to alleviate symptoms, promote healing, and restore normal function. It is crucial to consult with a healthcare professional, such as a chiropractor or physical therapist, for a proper diagnosis and individualized treatment plan. Here are some common treatment approaches:

Physical Therapy and Exercise

A skilled physical therapist can develop a tailored exercise program to strengthen the muscles supporting the shoulder joint and improve its range of motion. These exercises may include stretching, resistance training, and range of motion exercises.

Manual Therapy Techniques

Chiropractors and physical therapists may utilize manual therapy techniques, such as joint mobilization or soft tissue massage, to address restrictions in the shoulder joint and surrounding tissues. These techniques can help improve mobility and reduce pain.

Heat and Cold Therapy

Applying heat or cold therapy can provide relief and reduce inflammation in the shoulder joint. Heat therapy promotes blood flow and relaxation, while cold therapy helps numb the area and reduce swelling.

Medications and Injections

In some cases, healthcare professionals may recommend over-the-counter pain medications or prescribe stronger medications to manage pain and inflammation. Corticosteroid injections may also be administered to reduce pain and swelling in the shoulder joint.

Surgery

In severe cases or when conservative treatments fail to provide relief, surgical intervention may be necessary. Surgery can address structural abnormalities, repair damaged tissues, and restore the shoulder's full range of motion.

Prevention Tips for Maintaining Shoulder Health

Preventing the limitation of shoulder abduction is essential for maintaining overall shoulder health and reducing the risk of future injuries. Here are some tips to keep your shoulders in optimal condition:

1. Practice Good Posture

Maintain proper posture throughout the day to prevent unnecessary stress on the shoulder joint. Sit and stand tall with your shoulders pulled back and avoid slouching.

2. Warm Up and Stretch

Before engaging in physical activities or exercises, warm up your muscles and perform dynamic stretches to prepare the shoulder joint for movement. Stretching also helps improve flexibility and range of motion.

3. Strengthen Supporting Muscles

Incorporate shoulder-strengthening exercises into your fitness routine to build strength and stability in the muscles surrounding the shoulder joint. Focus on exercises that target the rotator cuff muscles specifically.

4. Avoid Overuse and Repetitive Movements

Avoid engaging in repetitive movements or activities that put excessive strain on the shoulder joint. Take regular breaks, switch sides, and modify your technique or equipment as necessary.

5. Listen to Your Body

Pay attention to any discomfort or pain in your shoulder. If you experience persistent or worsening symptoms, seek professional advice and avoid activities that exacerbate the pain.

Conclusion

The inability to abduct the shoulder past 90 degrees can significantly impact your daily life and activities. By understanding the causes, exploring treatment options, and implementing prevention strategies, you can improve shoulder mobility, reduce pain, and enhance overall shoulder health.
