Which of the following best defines the action of manipulation in chiropractic?

The action of manipulation in chiropractic is best defined as adjusting and mobilizing joints. This process involves skilled movements applied to joints to restore proper alignment, improve function, and alleviate pain. Manipulation is a cornerstone technique in chiropractic care, as it helps to enhance the mobility of joints and can facilitate the healing process in musculoskeletal conditions.

In chiropractic practice, manipulation aims to correct structural imbalances and improve the range of motion, contributing to overall physical health. Chiropractors use their hands to perform these manipulations with various techniques, targeting specific areas of the body where misalignments or restrictions may be present.

Understanding the specifics of manipulation is crucial for a chiropractic assistant, as it forms the foundation for many treatment approaches used in the field. Other options, while important aspects of a chiropractor's workflow, do not specifically define the action of manipulation. Assessing a patient's history and performing a thorough examination are critical components of patient care but do not directly involve the physical action of manipulating the joints. Providing educational materials is also essential for patient understanding and compliance but falls outside the definition of manipulation itself.
