There are a variety of ways to apply spinal traction. A description is given of how a massage chair performs spinal traction. Traction is a force used to stretch or elongate joint surfaces. Specifically, mechanical traction is defined as the application of a mechanical force to the body with a method that separates the joint surfaces and elongate the surrounding soft tissues. In the case of spinal traction, mechanical traction is used to flex joint surfaces and stretch soft tissues.

Spinal traction machines have capabilities of exerting a pulling force across the entire length of the spine. These machines must secure both ends of the patient's spine and then a pulling force is used to stretch the length of the spine. The pulling force is used in this case to stretch the soft tissues between the cervical disc.

When using a pulling force across the length of the spine, a spinal decompression machine must stretch each soft tissue area between all the cervical discs simultaneously. Do the soft tissue areas between the cervical discs get stretched equally? The force to affect this traction comes from pulling both ends of the spine.

Inversion therapy is another method commonly used to provide traction of the spine. The basic idea behind inversion therapy is to suspend you upside down by your feet. You can either wear boots or lay flat on an in version bed. With the boots, one must lock them onto a bar which requires a little gymnastics.

Inversion therapy uses gravity to affect the force. The patient's own weight is used to help stretch out the spine. Since the feet are held in place, the force is applied by both the angle of tilt and the patient's own weight.

Roller tables are commonly used to apply traction across the length of the spine. In this case, a patient is laid down on the table. The table is activated, and a roller passes up and down the length of the patient's spine.

Roller tables apply mechanical traction by passing the rollers across the spine. This applies an axial traction. As the roller passes each cervical disc, it will deflect the disc which stretches the soft tissues attached to it.

Massage chairs work on the same theory as roller tables. A roller is passed across the spine. The weight of the patient and the angle of the recline determine the force exerted on the disc. Unlike a roller table, however, massage chairs are able to adjust their angle.

Applying mechanical traction to the spine with a massage chair is using a roller. The roller causes each cervical disc to deflect. As each cervical disc deflects, a bending force is applied to the soft tissues between the cervical discs. The soft tissues are elongated.

Massage chairs are very versatile in a health care environment. They provide a variety of treatments for patients. They contain many different massage techniques. These chairs can be targeted for specific areas. Additional treatments include lower body stretching systems, heating elements throughout the chair and an MP3 player for music relaxation.

Massage chairs are versatile by providing a number of different treatment options. Many of the massage programs can be precisely controlled and directed to specific areas. This helps to see the direct effect that massage therapy has on the patient. Massage chairs also provide a relaxing environment with an MP3 player and headphones.
