Which shoulder movements are commonly restricted in patients with AWS?

1. Abduction, scaption, and horizontal abduction

2. Abduction, extension, and flexion

3. Adduction, scaption, and horizontal abduction

4. Adduction, extension, and flexion

The correct answer is: Abduction, scaption, and horizontal abduction

In patients with Axillary Web Syndrome (AWS), certain shoulder movements are often restricted due to the presence of fibrous bands or webs that form in the axillary region following surgical interventions, particularly in the context of breast cancer treatments. Abduction, scaption, and horizontal abduction are the movements most commonly affected in this condition. Abduction refers to lifting the arm away from the body, which can be challenging due to the tightness of the fibrous bands. Scaption is a movement that occurs in the plane of the scapula and is important for functional shoulder activity; restriction here can significantly impede daily movements. Horizontal abduction, which involves moving the arms from a front position to a side position while parallel to the ground, can also be limited due to the same fibrous restrictions. Understanding the mechanics involved with these movements in AWS helps clinicians address rehabilitation needs effectively by focusing on modalities that can alleviate restrictions and regain range of motion. This understanding is critical for guiding treatment plans tailored to restoring functionality and improving the quality of life for affected individuals.
