What is defined as the quantitative or qualitative measurements taken by PTs using a mechanical device?

The correct answer is objective examination. This term refers specifically to the measurements and evaluations conducted by physical therapists (PTs) that utilize mechanical devices to gather both quantitative data, such as range of motion or strength, and qualitative data, such as observations about a patient's physical condition.

In the context of physical therapy, an objective examination is essential because it provides measurable insights that help in diagnosing conditions, tracking progress, and developing treatment plans. By employing tools like goniometers, dynamometers, or electronic measurement devices, PTs can ensure that the assessments are consistent, accurate, and reproducible.

Other terms like functional assessment and performance assessment typically involve broader evaluations of a patient's abilities in their daily living and physical functions, rather than focusing strictly on the quantitative or qualitative measurements produced by mechanical devices. Clinical evaluation encompasses a wider scope, including patient history and subjective symptoms, rather than being limited to the objective, measurable data gathered through specific devices.
