Final answer:
Claudication pain generally improves with rest, while pseudoclaudication pain does not and may worsen when sitting or leaning forward. This difference in the response to rest is what helps distinguish claudication from pseudoclaudication.
Step-by-step explanation:
The action for relief that separates claudication from pseudoclaudication is the individual's response to rest. Claudication, which is often associated with peripheral arterial disease, is characterized by pain and cramping in the legs due to poor circulation and typically improves with rest. In contrast, pseudoclaudication, often related to spinal stenosis, does not improve with rest and may even worsen when the individual sits or leans forward.
Therefore, observing the change in symptoms with rest can help differentiate between the two conditions. While leg pain relief with cessation of activity suggests claudication, persistent or aggravated pain despite rest indicates pseudoclaudication.
