Proper Body Mechanics

Question 1

Situated at or directed toward the front of a body or object; the opposite of posterior.

Answer 1

Anterior

Question 2

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

Answer 2

Base of support (BOS)

Question 3

The point at which the mass of a body or object is centered.

Answer 3

Center of gravity (COG)

Question 4

Relates to a group of muscles bounded by the abdominal wall, the pelvis, the diaphragm, and the lower back that are contracted to assist in posture, balance, and stability.

Answer 4

Core stabilization

Question 5

Disturbance, impairment, or abnormality of the functioning of a body part.

Answer 5

Dysfunction

Question 6

THE VALUE OF PROPER BODY MECHANICS

Answer 6

✓ Conserves energy
✓ Reduces stress and strain on body structures
✓ Reduces risk of personal injury
✓ Promotes effective, efficient, and safe movements
✓ Promotes and maintains proper body control and balance
✓ Promotes effective and efficient respiratory and cardiopulmonary function

Question 7

The Core of the body involved the __ complex?

Answer 7

Involves the lumbar–pelvic–hip complex

Question 8

❖ Reliant on muscular endurance and neuromuscular
control
❖ Provides support to the spine and pelvis during
movement and maintains neutral pelvic alignment

Answer 8

CORE OF THE BODY

Question 9

The act of rubbing one object against another.

Answer 9

Friction

Question 10

Maintaining or pertaining to the same length.

Answer 10

Isometric

Question 11

Abnormally increased convexity in the curvature of the thoracic spine as viewed from the side.

Answer 11

Kyphosis

Question 12

Pertaining to a side; away from the midline of the body or a structure.

Answer 12

Lateral

Question 13

A component of a mechanical lever; it may be the force arm or the weight (resistance) arm; when the length of the force arm is increased or the length of the weight arm is decreased, a greater mechanical advantage is created for the lever system.

Answer 13

Lever arm

Question 14

Imaginary line that bisects the body in the sagittal
plane beginning at the head and continuing through
the COG

Answer 14

VERTICAL LINE OF GRAVITY (VLG)

Question 15

EVENTS THAT CHANGE A PERSON’S COG

Answer 15

➢ Adding ambulation aids
➢ Standing on one foot
➢ Reaching for an object
➢ Adjusting BOS

Question 16

An increase in one of the forward convexities of
the normal vertebral columns; a lumbar or cervical lordosis
can occur.

Answer 16

Lordosis

Question 17

Movement of the pelvis so the
anterior superior iliac spine moves anteriorly or posteriorly to
produce an anterior or a posterior tilt or inclination of the
pelvis.

Answer 17

Pelvic tilt (inclination)

Question 18

Lying down.

Answer 18

Recumbent

Question 19

Anteroposterior plane or body section that is parallel to the median plane of the body.

Answer 19

Sagittal plane
