Motor Exam Flashcards
C5 motor exam tests which muscle(s)?
Elbow Flexors
- Biceps Brachii - Brachialis
Describe patient positioning for the C5 motor exam when performing grade 3
The shoulder is in neutral rotation, neutral flexion/extension, and adducted. The elbow is fully extended, with the forearm in full supination. The wrist is in neutral flexion/extension.
Describe patient positioning for the C5 motor exam when performing grades 4 and 5
The shoulder is in neutral rotation, neutral flexion/extension, and adducted. The elbow is flexed to 90° and the forearm is fully supinated.
Describe patient positioning for the C5 motor exam when performing grades 0-2
The shoulder is in internal rotation and adducted with the forearm positioned above the abdomen, just below the umbilicus. The elbow is in 30° of flexion. The forearm and wrist are in neutral pronation/supination. Sufficient flexion of the shoulder must be permitted to allow the forearm to comfortably move over the abdomen.
C6 motor exam tests which muscle(s)?
Wrist Extensors
- Extensor Carpi Radialis Longus - Extensor Carpi Radialis Brevis
Describe patient positioning for the C6 motor exam when performing grade 3
The shoulder is in neutral rotation, neutral flexion/extension, and adducted. The elbow is fully extended, the forearm is fully pronated, and the wrist flexed.
Describe patient positioning for the C6 motor exam when performing grades 4 and 5
Same as grade 3, except the wrist is fully extended.
Describe patient positioning for the C6 motor exam when performing grades 0-2
Position the patient with the arm resting on the exam table. The shoulder is in neutral flexion/extension, neutral rotation, and adducted. The elbow is fully extended. The forearm is in neutral pronation-supination and the wrist fully flexed.
C7 motor exam tests which muscle(s)?
Elbow Extensors
- Triceps
Describe patient positioning for the C7 motor exam when performing grade 3
The shoulder is in neutral rotation, adducted, and 90°of flexion. The elbow is fully flexed with the palm of the hand resting by the ear.
Describe patient positioning for the C7 motor exam when performing grades 4 and 5
Same as grade 3, except the elbow is in 45° of flexion.
Describe patient positioning for the C7 motor exam when performing grades 0-2
The shoulder is in internal rotation and adducted, with the forearm positioned above the abdomen. The forearm is in neutral pronation/supination. The elbow is fully flexed. When checking Grade 2, sufficient flexion of the shoulder must be permitted to allow the forearm to clear and move over the chest and abdomen.
C8 motor exam tests which muscle(s)?
Long Finger Flexors
- Flexor Digitorum Profundus
Describe patient positioning for the C8 motor exam when performing grade 3
The shoulder is in neutral rotation, neutral flexion-extension, and adduction. The elbow is fully extended with the forearm fully supinated. The wrist is in neutral flexionextension. The metacarpal phalangeal (MCP) and proximal interphalangeal joints (PIP) are stabilized in extension.
Describe patient positioning for the C8 motor exam when performing grades 4 and 5
The same as grade 3, except the DIP joint is fully flexed.
Describe patient positioning for the C8 motor exam when performing grades 0-2
The shoulder is in neutral rotation, neutral flexion-extension, and adduction. The elbow is fully extended. The forearm is in neutral pronation-supination and the wrist in neutral flexion-extension. The MCP and PIP joints are stabilized in extension.
T1 motor exam tests which muscle(s)?
Small Finger Abductor
- Abductor Digiti Minimi
