Description

The goal of this clinical trial is to learn if motivational interviewing (MI) works to improve symptoms in people with thoracic outlet syndrome (TOS). TOS is a condition that causes long-term pain, numbness, and weakness in the arm and shoulder area. The main questions it aims to answer are: * Does MI lower pain and improve arm function in people with TOS? * Does psychological resilience predict treatment outcomes in people with TOS? Researchers will compare participants who receive MI sessions plus a home exercise program to those who receive a home exercise program alone. Participants will be randomly assigned to one of the two groups. Participants will: * Follow a home exercise program for 6 weeks * Some participants will also attend up to 4 motivational interviewing sessions * Complete questionnaires about pain, function, sleep, anxiety, and depression at the start and end of the 6-week program

Interventions

Motivational Interviewing (Behavioral)
A patient-centered counseling approach consisting of up to 4 face-to-face sessions delivered over 6 weeks. Sessions follow motivational interviewing (MI) principles, including collaborative engagement, open-ended questions, reflective listening, affirmations, and summarizing, to explore ambivalence and elicit change talk. Sessions address goal setting, decisional balance regarding behavior change, and strategies to support adherence to pain self-management and the home exercise program.
Home Exercise Program (Behavioral)
A standardized 6-week home exercise program taught face-to-face by a physiotherapist, including scalene and upper trapezius stretching (15 seconds per repetition), pectoralis minor stretching (15 seconds per repetition), median and ulnar nerve self-mobilization exercises, scapular stabilization exercises targeting the middle and lower trapezius and rhomboid muscles using elastic resistance bands, and diaphragmatic breathing training. The program is performed 3 times daily, 10 repetitions per exercise, for 6 weeks. Participants maintain an exercise diary to track adherence.
