What would be a sign of deep vein thrombosis (DVT) in extremities?

A sign of deep vein thrombosis (DVT) in extremities is the presence of palpable cords, which indicates the formation of a thrombosis in the veins. When blood clots form in the deep veins, particularly in the legs, they can cause the affected vein to become hardened and more prominent. This can lead to the sensation of a firm, cord-like structure when palpated through the skin.

In contrast, having a full range of motion, no tenderness in the calf, or normal circulation, sensation, motor function, and temperature (CSMT) would suggest that there is likely no thrombus present or that the condition is less severe. Tenderness, swelling, and changes in skin temperature or color are more commonly associated with DVT, whereas normal findings would not indicate the presence of a clot.
