The Activator Method is one of the most widely used instrument adjusting chiropractic techniques in the world. It is widely known for helping those suffering from back, neck and extremity pains, as well as headaches. Its proven effectiveness makes it a very useful complement to traditional chiropractic adjustments.

The instrument is called an Activator (of course) and is used as an alternative to traditional high velocity, low amplitude (HVLA) manual chiropractic adjustments, such as found in the Diversified Technique. The Activator is a spring-loaded, hand held device that allows chiropractors to provide a quick, low-force impulse at specific points and angles.

There are two theoretical advantages to an activator adjustment:

• High speed. The instrument is so quick that the body’s muscles are  less likely to tense in response and resist the adjustment. The lack of muscle resistance may facilitate effectiveness in the adjustment.

• Controlled force. The applied force is localised and does not put the joint in any compromised positions, such as bending or twisting.

The central feature of Activator Methods Chiropractic Technique is leg length analysis. When carefully and correctly performed, it is used to determine when and when not to adjust. An evaluation of apparent leg length is based on the theory that apparent differences in leg length may indicate the location of spinal and/or pelvic misalignments. This analysis is used in conjunction with routine physical examination approaches, such as static and motion palpation of the spine, to determine where the adjustment is needed.

By making the appropriate corrections, the Activator Method can help to restore motion, combat inflammation, and alleviate pain. Likewise, the Activator can remove blockages in nerve flow, restoring proper function and sensation to the affected area.
