Deck 9: Assistive Devices, Patterns, and Activities

Question 1

What degree of elbow flexion is recommended with the use of parallel bars or axillary crutches?

A) 0 to 10 degrees
B) 10 to 15 degrees
C) 20 to 25 degrees
D) 25 to 40 degrees

Answer 1

C
The patient should have approximately 20 to 25 degrees of elbow flexion when grasping the handpiece while keeping the shoulders level and relaxed.This slight amount of elbow flexion will allow the patient to efficiently lift or support the body by extending the elbows.

Question 2

At what level should the handgrip of a walker be placed?

A) The patient's fingertips
B) The patient's waist
C) The patient's olecranon process
D) The patient's wrist crease

Answer 2

D
The handgrip of the walker should be placed level with the patient's wrist crease,ulnar styloid process,or greater trochanters,with the walker positioned in front of and along the patient's sides and with the patient's arms straight along the sides.

Question 3

Pistol grip,offset shaft,quad,hemi,and crab are all types of which assistive devices?

A) Axillary crutches
B) Forearm crutches
C) Canes
D) Walkers

Answer 3

C
Types of canes include "J," "T," pistol grip,offset shaft,three- or four-legged,and four-footed (sometimes referred to as quad,hemi,or crab canes).

Question 4

What should a patient using bilateral axillary crutches do in the event of a forward fall?
