Fig. 11. “The Break,” No. 3.

Movement

Properly, a quick lateral movement of contact hand while the head is firmly held by the opposing hand.

Note: “The Break” is unfortunately named and it would be well if some less suggestive term were generally substituted.

THE ROTARY No. 1

For the correction of rotation only, and usable in the Cervicals from 2 to 7 inclusive.

Philosophy of the Rotary

A study of the Cervical articulations will make it clear that if a force be applied laterally to the spinous process the probable result will be a rotation of the vertebra, which swings one articular process back from its fellow but leaves the other in close, but modified, contact. Thus the spinous process may appear to the left while the left articular process is fitted firmly against that of the adjacent vertebra, while those on the right are separated. Similar rotation, modified only by the difference in shape of the vertebrae, occurs in the Lumbar region.

A movement applied to the spinous process might correct this condition or might complicate it according to the manner of application. But the most direct line of force for correction is along a line which would pierce the separated articular processes almost in an antero-posterior direction. The Rotary approaches this very closely. It is a setting forward of the articular process against its fellow by applying a movement directly to the transverse process, which lies very close to the articular process.
