Background: The potential consequences after breast cancer surgery are joint pain and sensitive disorders, the main sign of which is alterations in shoulder mobility. Design: Prospective randomized and double-blind pilot trial. Objective: To pilot the effectiveness of accessory joint and nerve mobilization techniques in order to get an overview of the joint capsule and nerve involvement in shoulder motion restriction. Participants: 18 women who were undergoing unilateral breast cancer surgery and axillary lymph node dissection. Setting: Women´s Health Research Group at Physical Therapy Department of University of Alcala, Madrid, Spain. Intervention: accessory joint mobilization versus neural mobilization. Follow-up: Six-month follow-up. Key outcomes: Range of motion, sensitive disorder, pain and upper limb functionality.
