1. What is post-adjustment care? → Monitoring and advising rest
2. Which grading scale is most commonly used to score equine ataxia in the US? → Mayhew/Nollet Ataxia Scale (0–5)
3. Which measurement tool is most commonly used in research to objectively quantify equine hindlimb lameness asymmetry? → Inertial measurement unit (IMU) body-mounted sensor systems
4. In equine spinal biomechanics, coupling refers to: → Simultaneous motion in more than one plane occurring together
5. In horses, the zygapophyseal (facet) joints are classified as: → Synovial (diarthrodial) joints
6. When adjusting the cervical spine of a horse, in which direction should the practitioner's thrust be directed to correct a C3 lateral flexion restriction? → Into the direction of restriction to gap the joint
7. What is the primary goal of equine rehabilitation following a chiropractic adjustment? → Restore normal movement patterns and prevent recurrence of subluxations
8. How often should equipment be sterilized or disinfected? → Between each patient use according to manufacturer guidelines
9. The 'swinging' (oscillating) motion of the equine head and neck during the walk primarily serves which biomechanical function? → Acts as a pendulum counterbalancing thoracolumbar rotation and aids forelimb protraction
10. The deep digital flexor tendon wraps around the navicular bone and inserts on which structure? → Distal phalanx (P3 / coffin bone)
11. Which structure forms the floor of the spinal canal at the lumbosacral junction and is a key landmark in equine epidural anesthesia? → Sacrococcygeal membrane
12. Which positioning principle ensures maximum safety when adjusting the horse's lumbosacral junction? → Keep the horse weight-bearing on all four limbs with even stance
13. A practitioner is bitten by a horse during a treatment session. After first aid, what documentation is legally and professionally required? → An incident report filed with the practice and the property owner notified
14. How should a professional handle a situation where they lack competence? → Refer the client to a qualified professional or seek additional training
15. A horse shows unilateral gluteal muscle atrophy on the right side. What finding on motion palpation would support a chiropractic component to this presentation? → Right-sided sacroiliac fixation with decreased joint play
16. What is the significance of obtaining a thorough patient history? → It reveals relevant conditions that may affect treatment planning
17. Which organization is primarily responsible for setting certification standards for equine chiropractors in the US? → American Veterinary Chiropractic Association (AVCA)
18. The ventral longitudinal ligament in the equine spine primarily prevents: → Excessive extension of the vertebral column
19. Why is specificity important in chiropractic adjustments? → To target the correct joint and direction
20. Which body system is most relevant to understanding tissue response to treatment? → The musculoskeletal and integumentary systems
21. Which professional behavior best demonstrates ethical compliance for an equine chiropractor working with performance horses? → Maintaining transparent communication with the veterinary team and honest documentation
22. Under AVCA certification standards, which condition must a practitioner satisfy to use the title 'Certified Animal Chiropractor'? → Complete an AVCA-accredited program and pass the AVCA certification examination
23. What is the term for the specific direction of thrust applied during a chiropractic adjustment? → Line of drive
24. How should treatment protocols be modified for patients with comorbidities? → Adjust parameters based on individual risk factors and contraindications
25. When an IASTM (instrument-assisted soft tissue mobilization) tool develops a burr or nick on its edge, the correct response is to: → Remove from service and have it professionally re-edged or replaced
26. When designing a rehabilitation exercise program for a performance horse, which principle should most guide the progression of exercises? → Gradual progressive overload paired with adequate recovery time between sessions
27. How many treatment sessions are typically recommended before reassessing a horse's response to chiropractic care for a chronic subluxation complex? → 2-3 sessions
28. What is the primary blood supply to the equine spinal cord at the thoracolumbar region? → Ventral spinal artery supplemented by segmental radicular arteries
29. During a portable electric height-adjustable table inspection, the hydraulic lift feels jerky and inconsistent. The most likely cause is: → Low hydraulic fluid level or air in the hydraulic line
30. Which personal protective equipment (PPE) is most critical when working in a stable with a suspected equine herpesvirus (EHV) outbreak? → Gloves and dedicated stable footwear or boot covers
