The clinical evaluation of patients suspected of having thoracic brachial outlet syndrome (TBS) is not standardized, as it may be for the lower limbs. Assessment of symptoms and functional impact is based on questionnaires (Disability of the Arm, Shoulder and Hand: DASH, Short Form 36: SF36, Mobility of the Arm and Shoulder: MASC, Thoracic and Upper limb ischemia Pain: TULIP), which are complex to complete, sometimes non-lateralized, and do not take into account the frequency of occurrence of certain gestures or the avoidance behaviours adopted by patients.

For avoidance behaviors, a recent tool has been proposed in the form of the Avoidance Daily Activities Photo Scale (ADAP shoulder scale). However, this questionnaire has not been translated into French and does not reflect the frequency with which patients are confronted with the different tasks proposed.

The aim of this study is to test the feasibility of a new questionnaire (PETRA), derived from the ADAP-shoulder scale, which is simple for patients to complete, quick to analyze and calculable directly by the doctor, and suitable for the general population, whether for initial assessment or follow-up.

The PETRA aims to assess avoidance behaviours in the face of daily tasks, but also the frequency of occurrence of these tasks in order to evaluate a disabling score that weights the avoidance index according to the degree of exposure to the proposed tasks.

The investigators hypothesize that the PETRA questionnaire could eventually be used routinely.

Inclusion Criteria:

• Adult,
• Person referred for suspected TDSB

Exclusion Criteria:

• Person unwilling to complete questionnaire and participate,
• Person unable to understand the objectives of the study.

Patients referred for thoraco-brachial outlet syndrome

Data will be shared upon reasonable request. Only de-identified data will be shared. Any data collected during the study may be shared. The protocol will be shared initially. Other documents may be shared at a later date upon request (e.g., the CRF to allow a collaborator to select the data they wish to access). The recipients of the data will be researchers. The data will be available for any purpose deemed relevant by the study investigator, based on a protocol provided by the requester, after verification of the obtaining of regulatory approvals, including the favorable opinion of an ethics committee.

The data will be shared after signing a negotiated data transfer agreement ( data access agreement), for the duration specified in the agreement.

The data will be made available via secure transfer (sharing platform approved by the university hospital: BlueFiles or Oodrive).
