Pictorial check of task frequency and upper‑limb avoidance (PETRA)
Official title: PETRA: Pictorial Assessment of Task Occurrence and Upper Limb Avoidance Behaviors
Run by University Hospital, Angers · NCT07031791 · Data updated 2026-11-12
This will test a new pictorial questionnaire (PETRA) with adults referred for suspected thoracic outlet syndrome to measure how often they do common tasks and whether they avoid using their affected arm.

Is this trial a fit for you?
✓Likely a good fit
Adults referred to Angers University Hospital for suspected thoracic outlet syndrome who can understand and complete questionnaires are the intended participants.
✕Probably not a fit
Patients unwilling or unable to complete the questionnaire or to understand the study objectives are unlikely to receive benefit from participation.

What this trial studies
Researchers at Angers University Hospital will test the feasibility of PETRA, a pictorial questionnaire derived from the ADAP‑shoulder scale, to capture task frequency and avoidance behaviors in patients with suspected thoracic outlet syndrome. Adult patients referred for suspected TOS will complete PETRA during outpatient visits, alongside routine measures such as DASH and SF‑36, to compare responses, completion time, and usability. The observational protocol emphasizes lateralized items and frequency scoring that existing questionnaires may not capture, and includes translation/local adaptation for French use. Findings will inform whether PETRA is practical for clinical use and ready for larger validation studies.
Why it matters
Potential benefit: If successful, PETRA could give clinicians a quicker, clearer picture of how thoracic outlet symptoms affect daily arm use and help target rehabilitation.
How similar studies have gone: A related pictorial tool (ADAP‑shoulder) has been proposed but not translated or widely validated in French, so PETRA is a novel, localized feasibility test.
