Question 1

Extreme ulnar deviation results in:&#10;A) a biomechanical block of wrist extension.&#10;B) shortening of the ulnar deviators.&#10;C) shifting of both rows of carnal bones.&#10;D) all of the above.

Accepted Answer

Extreme ulnar deviation can result in a biomechanical block of wrist extension due to the position of the radius and ulna. It also causes shortening of the ulnar deviators and can lead to shifting of both rows of carpals as the ulnar deviators pull on the hand bones. Therefore, all options are correct.

Question 2

In terms of biomechanical considerations,the firm cone should be placed with the small end in the _____ side of the palm.&#10;A) radial&#10;B) ulnar

Accepted Answer

This position is consistent with the biomechanics of the ulnar side of the hand.

Question 3

The following arch supports a cylindrical grasp:&#10;A) transverse.&#10;B) longitudinal.&#10;C) oblique.&#10;D) palmar.

Accepted Answer

This arch includes the carpometacarpophalangeal arches.These arches are formed for each finger by the corresponding metacarpal bones and phalanges.The arches are concave on the palmar surface;the "keystone" of each arch lies at the level of the metacarpophalangeal joint.In its simplest form,this arch supports a basic cylindrical grasp.If the arches are expanded,the hand is longer.This arch allows the palm to flatten and cup itself around objects.

Question 4

The most effective method to lengthen soft tissue is:&#10;A) high load brief stretch.&#10;B) passive range of motion (ROM).&#10;C) low-load prolonged stretch.&#10;D) joint mobilization.

Accepted Answer

Low-load prolonged stretch involves holding the tissues in a low-lengthened position for a total end range time.A low-lengthened position is a passive position with a low-load stress (in which the patient feels a slight stress but one that he or she can tolerate for a significant amount of time).

Question 5

Digit platforms should only be used:&#10;A) at night.&#10;B) when proximal realignment does not relax the digits.&#10;C) when the digits are at risk for contracture.&#10;D) all of the above.

Accepted Answer

Digit platforms should be used when proximal realignment does not relax the digits, when the digits are at risk for contracture, and at night.

Question 6

The hand-based thumb abduction splint is applied for:&#10;A) functional activities.&#10;B) immobilization.&#10;C) inhibition of thumb adduction.&#10;D) contracture prevention.

Accepted Answer

This splint places the thumb in a position for function.

Question 7

At rest,the second metacarpal is aligned:&#10;A) with the ulna.&#10;B) with the radius.&#10;C) midline between the radius and ulna.&#10;D) with the carpal arch.

Accepted Answer

The second metacarpal bone is aligned with the radius bone in a resting position. This is because the radius bone is the larger of the two bones in the forearm and its position influences the alignment of bones in the wrist and hand.

Question 8

The concept of dual obliquity states that objects held in the hand assume _____ oblique angle(s).&#10;A) 1.&#10;B) 2.&#10;C) 3.&#10;D) 4.

Accepted Answer

Because of a successive decrease in the length of the metacarpals from the radial to the ulnar side,objects held in the hand assume two oblique angles.

Question 9

The suggested splint for a proximal interphalangeal contracture is a _____ splint.&#10;A) serpentine&#10;B) tone and positioning&#10;C) belly gutter&#10;D) resting

Accepted Answer

This splint provides stretch to the joint to decrease the contracture.

Question 10

The literature reviewing dorsal- and volar-based splinting is:&#10;A) supportive of dorsal-based splints.&#10;B) supportive of volar-based splints.&#10;C) inconclusive.&#10;D) not in support of splinting at all.

Accepted Answer

The variability in published studies makes decisions regarding dorsal- versus volar-based treatment difficult to reach based on available research.Therapists must still evaluate each patient individually to determine the effect of variables on splinting outcomes.

Question 11

Proper palmar support implies that the:&#10;A) third metacarpal head is superior to the other metacarpal heads.&#10;B) splint progresses beyond the distal palmar crease.&#10;C) first metacarpal is supported.&#10;D) all of the above.

Accepted Answer

The answer of Proper palmar support implies that the:&#10;A) third...

Question 12

The effectiveness of the inflatable pressure splint has:&#10;A) not been proven.&#10;B) been proven related to inhibition of spasticity.&#10;C) been proven related to increasing functional use of the upper extremity.&#10;D) been proven regarding contracture prevention.

Accepted Answer

The answer of The effectiveness of the inflatable pressure splint...

Question 13

The collateral ligaments are lengthened by:&#10;A) digit extension.&#10;B) digit flexion.&#10;C) application of resting splints.&#10;D) thumb opposition.

Accepted Answer

The answer of The collateral ligaments are lengthened by:&#10;A) digit...

Question 14

Loss of distal interphalangeal joint flexion may be due to:&#10;A) oblique retinacular ligament contracture.&#10;B) joint contracture.&#10;C) both a and b.&#10;D) none of the above.

Accepted Answer

The answer of Loss of distal interphalangeal joint flexion may...
