TOS Compass · symptom-mapping tool
Understand your
arm symptom pattern
Focused questions, a body map and three short home movements help organize your symptoms before a professional assessment. The purpose is to document the pattern—not to diagnose yourself.
Answers remain on your device and are not sent or stored.
Important: This is an original educational tool informed by features described in the professional literature. The result reports compatibility with a pattern warranting assessment—not a numerical probability of disease. Its score is not a validated questionnaire, does not diagnose TOS and does not determine the need for imaging, treatment or surgery.
Do not perform the home movements if shoulder elevation has been restricted, after recent surgery or injury, or if you have sudden swelling, colour change, a cold hand, new weakness, chest pain or shortness of breath.
