D. None of These
C. Hook Grasp
Synergistic actions of the wrist muscles are noted in the following:

B. When the thumb is flexed, the palmaris longus aids the movement by tensing the fascia of the palm; to prevent flexion of the wrist, the extensor digitorum contracts
C. When the 5th finger is abducted, the flexor carpi ulnaris furnishes countertraction on the pisiform; to prevent wrist ulnar deviation, the flexor carpi radialis contracts
D. All of these

TRUE OR FALSE: In DIP or PIP Arthroplasty, the goal of the PT is to restore 70° PIP flexion and full extension.
True
TRUE OR FALSE: Finkelstein test usually presents as (+) in most people.
True
Differentiate tenosynovitis from tenovaginitis.
Tenosynovitis - inflammation of the synovial membrane covering the tendon
Tenovaginitis - inflammation with thickening of a tendon sheath
TRUE OR FALSE: In sensory re-education, a PT must determine the most irritating sensory stimulus then re-introduce it first to help pt adapt to it faster.
False.
Start with least irritating as to not discourage the pt then progress to the most irritating sensory stimulus.
TRUE OR FALSE: The ulnar nerve enters the hand through a trough formed by the pisiform bone & hook of the hamate bone.
True
Then, the volar carpal ligament and palmaris brevis muscle covers the ulnar nerve, forming the tunnel of Guyon.

Differentiate central slip-splitting & central -slip sparring. Which technique needs more time of immobilization?
Slip-sparring - moving the tendon to the side
Slip-splitting - splitting the tendon in half
central slip-splitting needs more days of immobilization (3-5 days) post-op & will produce slower ROM.
