The chiropractor must select the appropriate technique for each patient's unique situation and be able to execute that technique with great skill. The subluxated vertebra is adjusted through the introduction of small forces onto the spine. These forces are intended for the body's use in repositioning the vertebra. The chiropractor must know as precisely as possible, where, when, and in what direction the force should be introduced. The ability to perform a technique expertly requires much practice under close supervision.
Perfect practice makes perfect.
