What is the primary limiting factor for exercise in the client with peripheral artery disease (PAD)?

In clients with peripheral artery disease (PAD), the primary limiting factor for exercise is leg pain, commonly referred to as intermittent claudication. This pain occurs due to inadequate blood flow to the leg muscles during physical activity, which is a direct consequence of narrowed arteries. As the client engages in exercise, the demand for oxygen increases, but the diseased arteries fail to deliver sufficient blood to meet this demand, leading to discomfort and pain.

This leg pain often forces individuals to stop or reduce their level of activity to alleviate symptoms, limiting their overall capacity to engage in exercise. Managing PAD and its symptoms, particularly leg pain, is essential for improving functional capacity and overall health in affected individuals.

While muscle strength, joint flexibility, and cardiovascular endurance are important aspects of fitness, they may not be the primary constraints in a client with PAD. Addressing leg pain is crucial, as alleviating this symptom can enhance the client’s ability to exercise more comfortably and effectively.
