WorksheetsFM Wrist - Review #1
Total questions: 13
Worksheet time: 7mins
What is the ideal wrist position for functional grasp activities?
20-30 degrees wrist extension
10 degrees wrist extension
20-30 degrees wrist flexion
10 degrees wrist flexion
T/F: When bearing down on your wrist, 80% of the full force passes through the articular disc to the ulna
True
False
What is the average static functional position of the wrist?
10-15 degrees of extension and 10 degrees ulnar deviation
10-15 degrees of flexion and 10 degrees ulnar deviation
10-15 degrees of extension and 10 degrees radial deviation
T/F: In order for radial deviation to occur there is a synergy between the wrist flexors and extensors.
True
False
T/F: Wrist extensors can generate greater isometric torque than wrist flexors.
True
False
Why can we flex our wrist more than extend?
Palmar Tilt
Ulnar Tilt
Radial Tilt
Volar Tilt
Which muscle has the greatest torque at the wrist?
flexor carpi radialis
flexor carpi ulnaris
palmaris longus
The synergy of ECRL, ECRB, and ECU will result in:
wrist extension with radial deviation
balanced radial deviation
balanced wrist extension
wrist flexion with radial deviation
DeQuervain's tenosynovitis is a result of repetitive movement patterns in 1st compartment of the wrist. Involved muscles include: (select all)
extensor pollicis brevis
extensor carpi radialis brevis
extensor digitorum
abductor pollicis longus
T/F: Palmar carpal ligament prevents bowstringing during extension.
True
False
What bone serves as the axis of motion for all wrist movements?
(a)
Your therapist asks you to make a "thumbs up" sign with the hand of your injured UE. As you flex your fingers into a fist, your wrist flexes involuntarily, too. What nerve is injured?
Median
Ulnar
Radial
The same therapist asks you to try to hold a pencil. You are able to curl your fingers around the pencil, and your wrist involuntarily flexes again. Your grip around the pencil isn't strong. Why?
ACTIVE insufficiency of the wrist EXTENSORS
ACTIVE insufficiency of the wrist
FLEXORS
PASSIVE insufficiency of the wrist EXTENSORS
PASSIVE insufficiency of the wrist
FLEXORS
