Patients referred for suspected thoracic outlet syndrome causing and healthy asymptomatic subjects will be included. After signing the consent, the subject will have a clinical and paraclinical examination. Age, sex, height, weight, side of clinical symptomatology will be collected. Medical history current treatments will also be noted. The examination of transcutaneous oximetry dynamic measurement with palmar face of both forearms during two consecutive maneuvers known as the "candlestick" (hands up). The most symptomatic arm value in patients and the dominant arm in the control group will be noted. In case of DROP between 0 and -25 mmHg, in addition to the maneuvering of the "candlestick", the other maneuvers such as those of Wright, Roos, Tinel and Adson will be realized. The results of any additional examinations and / or pre- and post-operative consultations will be collected. Subjects complete two Quality of Life questionnaires: the SF-12 (Short Form 12) and the DASH questionnaire (Disabilities of the Arm, Shoulder and Hand).
