What type of drug restricts an individual's ability to move?

The correct answer identifies a category of drugs specifically designed to modify or control behavior by affecting the central nervous system. Chemical restraints are sometimes used in medical or psychological contexts to limit an individual’s ability to move freely, typically in situations where a person's behavior poses a danger to themselves or others. These medications can produce sedation or alter perceptions in a way that restricts physical movement, thereby serving as a means to manage actions or reactions that are considered problematic.

In contrast to chemical restraints, physical restraints involve using devices or techniques to restrict physical movement, while psychotropic medications encompass medications taken for mental health conditions, which may or may not serve a restraining function in terms of mobility. Mobility aids are designed to assist individuals in moving safely, and do not restrict movement at all. Thus, the focus on chemical restraints highlights their specific purpose and mechanism within the context of behavioral management.
