When experienced Doctors of Chiropractic prepare for the NBCE Special Purposes Examination for Chiropractic (SPEC), their primary concern is rarely the test format—it's the actual testable content.

If you've been in clinical practice for years, you perform physical exams and orthopedic testing daily. However, board exams test standardized, textbook details that you may not have reviewed since chiropractic college.

To help you study efficiently, here is an in-depth breakdown of the most frequently tested Neuromusculoskeletal (NMS), Neurological, Physical Exam, and Technique topics on the NBCE SPEC exam.

1. High-Yield Orthopedic Tests

The SPEC heavily evaluates your ability to select the correct orthopedic test, perform its procedures, and interpret positive findings for differential diagnosis.

Cervical & Upper Extremity Tests

• Spurling’s Test (Foraminal Compression): Local pain indicates facet joint involvement; radicular pain indicates nerve root compression on the side of lateral flexion.

• Cervical Distraction Test: Relief of pain indicates foraminal encroachment or nerve root compression; increased local pain suggests muscle/ligament strain.

• Bakody’s Sign (Shoulder Abduction Test): Relief of cervical radicular symptoms when resting the palm on top of the head indicates a  C 5​  or  C 6​  disc herniation/radiculopathy.

• Thoracic Outlet Syndrome (TOS) Battery: Know the specific neurovascular structures compromised in Adson’s(scalenus anticus), Wright’s/Hyperabduction (pectoralis minor/coracoid), and Eden’s/Costoclavicular (first rib and clavicle) tests.

Lumbar & Pelvic Tests

• Straight Leg Raise (SLR) & Bragard’s: Pain between  35 ∘ and  70 ∘ suggests space-occupying disc herniation. Bragard’s (dorsiflexion at point of pain) confirms sciatic nerve origin over hamstring tightness.

• Well Leg Raise (Fajersztajn’s): Radiating pain into the involved/affected leg during elevation of the uninvolvedleg strongly indicates a medial disc herniation.

• Patrick’s / FABERE Test: Flexion, Abduction, External Rotation, Extension. Pain deep in the anterior hip indicates hip joint pathology; pain in the posterior SI region indicates sacroiliac dysfunction.

• Gaenslen’s & Yeoman’s Tests: Differentiating SI joint strain/sprain from lumbar facet pathology.

2. Neurological Examination Breakdown

You must be able to correlate neurological deficits directly to specific spinal motor units and peripheral nerves. 

       Spinal Level  ➔  Motor Function  ➔  Reflex Tested  ➔  Sensory Distribution
       
       C5            ➔  Biceps / Deltoid ➔  Biceps          ➔  Lateral Deltoid
       C6            ➔  Wrist Extensors  ➔  Brachioradialis ➔  Lateral Forearm / Digits 1-2
       C7            ➔  Wrist Flexors    ➔  Triceps         ➔  Middle Finger (Digit 3)
       L4            ➔  Tibialis Ant.    ➔  Patellar        ➔  Medial Leg & Foot
       L5            ➔  Ext. Hallucis    ➔  (None standard) ➔  Dorsum Foot & Great Toe
       S1            ➔  Peroneus Longus  ➔  Achilles        ➔  Lateral Foot & Heel

Key Neurological Mastery Areas:

• Motor Grading Scale: Memorize the standard 0–5 scale (0 = no contraction, 3 = movement against gravity but no resistance, 5 = normal power).

• Deep Tendon Reflexes (DTR): 0 (absent), 2+ (normal), 4+ (hyperactive with clonus).

• Upper vs. Lower Motor Neuron Lesions:

  • UMN Lesion: Hyperreflexia, spasticity, positive Babinski/Hoffmann, pathological reflexes present.

  • LMN Lesion: Hyporeflexia, flaccidity, fasciculations, muscular atrophy.

3. Physical Examination & Vital Sign Red Flags

The SPEC tests your ability to detect non-musculoskeletal and systemic disease during initial consultations:

• Hypertension Thresholds: Recognizing hypertensive crisis ($\ge 180/\ge 120\text{ mmHg}$) requiring immediate emergency referral versus moderate hypertension requiring medical co-management.

• Abdominal Aortic Aneurysm (AAA): Pulsatile abdominal mass larger than $3\text{ cm}$ or lateralization of abdominal aortic pulsation. Key rule: High-velocity adjustments are contraindicated in patients with known AAA.

• Thoracic Auscultation: Identifying abnormal breath sounds (rales/crackles in pulmonary edema or pneumonia) and heart murmurs (aortic stenosis radiating to carotids).

4. Chiropractic Technique & Motion Segment Analysis

Technique questions on the SPEC do not favor one proprietary brand over another; instead, they test standardized biomechanical principles and adjustive mechanics:

Bridge the Gap Between Clinic and Exam

You already have the clinical experience—you just need to align your recall with the specific academic definitions used by the NBCE.
