Application Based Behavior Nudging Active Breaks Versus Conventional Ergonomic Education for Thoracic Mobility and Neck Pain in Office Workers

This study is about neck pain and upper-back movement in office workers. Sitting for long hours and working on computers can contribute to neck and upper-back discomfort. The study will compare two approaches: App-Based Active Breaks: An app will remind participants to take 1 minute movement breaks during their workday. Conventional Approach: Participants will receive ergonomic advice and exercises to do twice a day. The exercises include simple movements for the upper back, shoulders, and neck. Participants will be assessed for neck pain, neck disability, upper-back movement, muscle endurance, and work-related difficulties before and after the program. The active program will last 6 weeks, followed by a final assessment in week 8. Participation is voluntary, and participants can withdraw at any time. Their personal information will be kept confidential. The study aims to find out whether taking short, regular movement breaks with app reminders can help reduce neck pain and improve upper-back movement in office workers.
