PRINCIPLES OF BODY MECHANICS

Question 1

An imaginary line that bisects your body in the sagittal plane beginning at your head and continuing through your pelvis and through your COG

Answer 1

VERTICAL GRAVITY LINE

Question 2

It can be used for light objects that can be lifted easily with one upper extremity.

Answer 2

ONE LEG STANCE LIFT

Question 3

It is only a half squat is performed so the hips remain above the level of the knees. The lifter’s feet are parallel to each other and remain behind the object, with the upper extremities parallel to each other.

Answer 3

POWER LIFT

Question 4

the lifter aligns the body by kneeling on one knee positioned behind and on one side of the object and the opposite lower extremity to one side of the object with the foot at and the hip and knee flexed approximately 90 degrees.

Answer 4

HALF KNEELING LIFT

Question 5

Most appropriate position to lift an object below the level of the hips

Answer 5

STOOP

Question 6

Muscle groups responsible for provides support to the spine and pelvis during movement and maintains neutral pelvic alignment.

Answer 6

CORE MUSCLES

Question 7

The area on which an object rests and that provides support for the object.

Answer 7

BASE OF SUPPORT

Question 8

IMPORTANCE OF PROPER BODY MECHANICS

Answer 8

a. Energy conservation
b. Reduce stress on joints
c. Promote safe movements
d. Maintain proper body control and balance

Question 9

The use of one’s body to produce motion that is safe, energy conserving, anatomically and physiologically e cient, and maintains body balance and control.

Answer 9

BODY MECHANICS

Question 10

This phenomenon can occur when the patient holds his or her breath and air is trapped in the thorax, which increases intrathoracic pressure.

Answer 10

a. Valsalva Maneuver

Question 11

rationale for Lumbar Lordosis Posture

Answer 11

Lumbar spine stability is increased as a result of the approximation of the vertebral facets.

Question 12

NOT an appropriate guideline during Pushing, Pulling, Reaching, and Carrying Activities?

Answer 12

carrying a small child on one hip

Question 13

a technique to achieve stability when attempting to lift, reach, push, pull or carry an object?

Answer 13

tighten core muscle

Question 14

VALUES OF PROPER BODY MECHANICS

Answer 14

1. Energy Conservation
2. Maintain proper body control and balance
3. effective, efficient and safe movements
4. effective, efficient respiratory and cardiovascular function
5. reduces strain on the joints, muscle, ligaments and soft tissue

Question 15

an object which an object rest and provides support for the object

Answer 15

STABILITY

Question 16

vital before attempting to lift, reacg, push, pull or carry an object

Answer 16

STABILITY

Question 17

HOW TO ACHIEVE STABILITY

Answer 17

1. tighten your core
2. increase base of support
3. lowering your center of gravity
4. maintain vertical line within BOS
5. position feet farther apart in anteroposterior direction
6. proximal is greater than distal muscles

Question 18

BEFORE LIFTING

Answer 18

1. Prepare oneself __ and __
2. Determine the ___ of the __ to be lifted
3. identify patient’s ___ by asking patient or checking ____
4. if the item ____ moved easily, get __
5. determine the best ___ for moving object before moving it.
6. Patients and persons who provide ___
   must be ___ about their responsibilities
   and task before performing the activity
7. Ask them to _____ to ensure
   comprehension
8. Instructions and directions should be __ and __
9. use (“___, ___, ___, ___)
10. anticipate unusual or unexpected _____

Question 19

PRECAUTIONS DURING LIFTING
STATEMENT TRUE OR FALSE:
A foot or ladder may be cannot be used to reach an object located above the head. If object is below waist, stoop or squat or raise object to avoid trunk flexion

Answer 19

FIRST STATEMENT IS FALSE, SECOND STATEMENT IS TRUE

Question 20

PRECAUTIONS DURING LIFTING
STATEMENT TRUE OR FALSE:

 Be aware of your personal abilities and limits of your strength. You should do Valsalva maneuver while lifting and All lifts should be initiated with co-
contraction of your co-stabilizers before the lift

Answer 20

FIRST STATEMENT IS TRUE, SECOND STATEMENT IS FALSE.

Question 21

increased intrathoracic pressure

Answer 21

VALSALVA MANUEVER

Question 22

caused by forcible exhalation against a closed glottis

Answer 22

VALSALVA MANUEVER
