When should exercise be modified after TOS surgery according to postoperative precautions?

• A. If symptoms last more than 2 hours
• B. Only if there is fever
• C. After 6 weeks regardless
• D. If symptoms last more than 24 hours

Answer: (A)

In postoperative rehab after thoracic outlet syndrome surgery, the signal to adjust exercise is based on how long symptoms last after activity. If symptoms persist for more than about two hours, that indicates the exercise is provoking neurovascular irritation and should be modified or paused to protect healing tissues. This symptom-driven approach lets you progress safely while avoiding prolonged nerve or vascular strain. Fever would suggest an infection and isn’t the criterion for adjusting exercise; a rigid rule like “never change anything for six weeks” ignores individual healing, and waiting a full day (24 hours) before modifying could allow ongoing irritation to worsen.
