• Acceleration: The rate of change of velocity in respect to time.
• Adjustment: A specific directional thrust maneuver or application of forces applied to a subluxated vertebra that sets the vertebra into motion with the intent to reduce and/or correct the vertebral misalignment, thus improving the neurological component of the vertebral subluxation complex along with vivification of the affected tissues and body functions.
• Angular Rotation: The abnormal excursion of the cervical spine and skull as a unit about the vertical axis of the body and into either the right or left frontal plane of the body, thereby producing gravitational stresses resulting in rotations of the vertebrae and tractionalization of the contents of the spinal canal and nerve roots.

• Chiropractic: Chiropractic is a health care discipline which emphasizes the inherent recuperative powers of the body to heal itself without the use of drugs or surgery.
  
  The practice of chiropractic focuses on the relationship between structure (primarily the spine) and function (as coordinated by the nervous system) and how that relationship affects the preservation and restoration of health.
  
  Of primary concern to the doctor of chiropractic are abnormalities of structure or function of the vertebral column known clinically as the vertebral subluxation complex. The subluxation complex includes any alteration of the biomechanical and physiological dynamics of contiguous spinal structures which can cause neuronal disturbances.
• Chiropractic adjustment: This term refers to a wide variety of specific manual interventions that may be high or low velocity; short or long lever; high or low amplitude; with or without recoil.
  
  Chiropractic adjustments are directed at specific anatomical regions of the vertebral spine. The purpose of the Chiropractic adjustment is to correct vertebral subluxations which can cause alteration of the biomechanical and physiological dynamics of contiguous spinal structures and manifest neuronal disturbances.
• Chiropractic Analysis: A chiropractic analysis is performed on a routine basis to determine the patient's need for spinal adjustments. A chiropractic analysis may include (but certainly is not limited to) two or more of the following procedures: instrumentation (skin temperature differential analysis), chiropractic x-ray analysis, spinal static and motion palpation, postural analysis, leg-length comparison tests, muscle strength measures, and other chiropractic analysis procedures.
• Chiropractic Assessment: The process of integrating the clinical analysis to determine the best mode to address and monitor the correction of vertebral subluxation and other malpositioned articulations and structures. Specifically it is the integrating of history with physical, imaging and instrumentation examinations.
• Chiropractic Care: This term refers to the behaviors, methods, procedures, etc., that chiropractic practitioners employ in the case-management of patients.
• Chiropractic Diagnosis: Such clinical processes as are necessary in the professional judgment of the attending doctor of chiropractic to determine the need for care and, in particular, to detect the presence, location and nature of chiropractic lesions (subluxation and attendant biomechanical, biochemical, structural and neurophysiological problems, etc.) and prepare and administer an appropriate course of care within the realm of chiropractic.
• Chiropractic Practice Objective: The primary professional practice objective of chiropractic is to reduce or correct vertebral subluxations and other malpositioned articulations and structures in a safe and effective manner.
• Chiropractor aka Doctor of Chiropractic aka D.C., aka DC: A practitioner of chiropractic.
• Chiropractic Neuro-Spinal Hygiene (NSH): NSH is a preventive spinal health program designed to educate and empower individuals to improve their spinal and general health, and their sense of well-being.
  
  NSH assists individuals in maintaining a healthy spinal column and nervous system through active personal empowerment in daily procedures promoting spinal flexibility, strength, resiliency, stress management, proper spinal and body ergonomic habits, and optimal spinal and neurological health.
• Contractured Leg: An apparent difference in the leg length of a C1 subluxated individual when measured in the supine position, and resulting from spastic contracture of the extensor musculature of the spinal column. Frequently called the "short leg".
• Curvilinear Motion: The motion of an object along a curved path.
• Direction: The line or course along which an object moves.
• Disequilibrium: Loss or lack of stability.

• Joint Play (Accessory Movement): The small, precise joint movements, not under the control of the voluntary muscles or patient, that are necessary to permit normal voluntary joint movement. Joint play may include spin, glide and roll of articulation. The full range of active movement of a joint without practitioner assistance is a combination of voluntary movement (voluntary muscles) and joint play.
