👉 The term "concatervate" is a medical term that refers to the process of stimulating or activating the respiratory muscles by applying electrical current. This can be done during physical therapy, such as in exercises like swimming or cycling, where it helps improve lung function and prevent hoarseness. It's also used in some cases to treat conditions related to respiratory problems, such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis.
