Deck 37: Spinal Cord Injury

Question 1

The patient has a C5 quadriplegia.We can anticipate that he or she has innervation of which of the following?

A) Upper trapezius, deltoids, biceps, levator scapulae, wrist flexors
B) Latissimus, deltoids, biceps, supinators, pronators
C) Upper trapezius, diaphragm, levator scapulae, biceps, and supinators.
D) A and B

Answer 1

C
Options (A)and (B),and therefore (D)as well,are not possible because they include muscles that are innervated by lower spinal nerves.

Question 2

The patient has a C6 quadriplegia.We can anticipate that he or she has innervation of which of the following?

A) Deltoids, latissimus, biceps, radial wrist extensors
B) Latissimus, serratus, biceps, triceps
C) Deltoids, biceps, triceps, hand intrinsics
D) All of the above

Answer 2

A
Option (A)is the only choice that does not include muscles that are innervated by spinal nerves below C6.

Question 3

For the person with C6 quadriplegia,it is desirable to develop some tightness in the long finger flexors because _____________________.

A) The tightness of the finger flexors, combined with active wrist flexion, can produce some functional grasp through tenodesis action
B) The tightness of the finger flexors, combined with active wrist extension, can produce some functional grasp through tenodesis action
C) The tightness of the finger flexors combined with weak but active wrist flexion can produce a functional hook grasp

Answer 3

B

Question 4

The occupational therapist can help achieve the desired flexor tightness necessary for tenodesis grasp by doing which of the following?

A) Ranging finger flexion with the wrist extended and finger extension with the wrist flexed
B) Ranging finger flexion with wrist flexed and finger extension with wrist extended
C) Ranging finger flexion with wrist at neutral and extension with wrist extended

Question 5

The person with C6 quadriplegia may be able to assist in transfers by locking the elbows in extension and performing shoulder _________________.

A) Depression, extension, and adduction
B) Depression, external rotation, and adduction
C) Adduction and elbow flexion
D) Horizontal abduction and humeral adduction
