If a patient is experiencing weakness, which term should be used?

The term that should be used when a patient is experiencing weakness is "asthenia." This term specifically refers to a state of physical weakness or lack of energy. In medical contexts, asthenia encompasses a variety of conditions where a patient feels fatigued or has diminished strength, which is crucial for understanding and addressing the patient’s needs during physical therapy.

The other terms do not accurately convey the experience of weakness. "Algesia" pertains to sensitivity to pain, "dyspnea" relates to difficulty in breathing, and "neuralgia" refers to pain along a nerve path. Understanding these distinctions allows healthcare professionals to communicate effectively about a patient's symptoms and guide appropriate interventions.
