Practicing chiropractors are faced with the challenge of determining when to adjust. Trying to apply examination procedures, such as medical orthopedic tests, which do not indicate the presence or correction of vertebral subluxations, has frustrated many doctors.
The concept of nerve interference is often challenging to patients. Their confusion is compounded when the chiropractor claims to be subluxation based, but bases care on the presence or absence of symptoms.
The ideal clinical examination procedure:
• Will provide objective measurements.
• Is completely non-invasive.
• Provides a reliable and valid assessment of the functional status of the nervous system.
• Provides a means of re-examination to track progress.
• Is time and cost effective.
• Uses protocols supported by peer-reviewed publications.
• Is applicable to persons of all ages, including infants, toddlers, children, adolescents and adults.
• Facilitates patient education by providing easy-to-understand, tangible evidence.
• Is suitable for spinal screening.
Advances in technology, such as electromyography (EMG) and thermal scanners that are designed especially for chiropractors, have resulted in instrumentation that empowers the chiropractor with objective evidence of nervous system function. Enabling the chiropractor to evaluate aspects of functional integrity, which are related to the analysis of vertebral subluxation, is essential. For instance:
1. Static surface EMG (sEMG) measures the electrical activity in the muscles surrounding the spine. This test enables the chiropractor to objectively evaluate the innate response of the paraspinal muscles to gravity. Tonic muscle activity is assessed with static sEMG.
2. Dynamic surface EMG allows the chiropractor to graph up to four channels of sEMG activity as the patient goes through ranges of motion. The result is an objective assessment of voluntary motion.
3. Paraspinal Infrared Temperature analysis evaluates the integrity of the autonomic nervous system, which controls organs, glands, and blood vessels. It allows the chiropractor to relate vertebral subluxation to autonomic function. A rolling thermal scanner allows the doctor to examine infants, children, and adult patients in a single pass.
4. Computerized inclinometry measures ranges of spinal motion. These measurements relate to the biomechanical component of vertebral subluxations.
5. Pressure algometry evaluates sensory function by measuring the pressure/pain thresholds of tender regions along the spine.
Having the ability to display dramatic color graphics in a format that is easy to apply clinically and to communicate effectively and objectively to patients, is the goal of every chiropractor. Seeking technical certainty through advanced methods and technologies should be the path for each of us. Improve your patient communication and commit to the vision of lifetime, subluxation-based wellness care and raise your practice to a higher level.
