Q

Principles of BODY MECHANICS

A

Balance is maintained and muscle strain is avoided as long as the line of gravity passes through the base of support

–Start body movement with proper alignment
–Stand as close as possible to the object to be moved
–Avoid stretching, reaching and twisting

The wider the base of support and the lower the center of gravity, the greater the stability. Before moving objects, put your feet apart, flex the knees, hips and ankles

Balance is maintained in minimal effort when the base of support is enlarged in the direction in which the movement will occur

–Enlarge the base of support by moving the front foot forward when pushing an object
–Enlarge the base of support by either moving the rear leg back (facing the object or moving the front foot forward if facing away from the object) when pulling object

Objects that are close to the center of gravity are moved with least effort

–Adjust the working area to waist level, and keep the body close to the object

The greater the friction against the surface beneath an object, the greater the force required to move an object. Provide a firm, smooth, dry bed foundation before moving the client in bed

Pulling creates less friction than pushing

The heavier an object, the greater the force needed to move an object

–Encourage the client to assist as much a possible (pushing or pulling)
–Use own body weight to counteract the weight of the object
–Obtain the assistance of other persons or use mechanical devices to move objects that are too heavy

Move objects along a level surface requires less energy than moving an object up an inclined surface or lifting it against the force of gravity

–Instead of lifting objects, pull, push, roll or turn
–Lower the head of the client’s bed before moving the client up in bed

Continuous muscle exertion can result in muscle strain and injury

-length is equal to the distance between the greater trochanter and the floor

-on the stronger side of the body

-Place the cane forward 15 – 25 cm (6-10 inches) keep body weight on both legs

-Move weaker leg forward to the cane so body weight is divided between the cane and the stronger leg.

-Advance the stronger leg past the cane (so the weaker leg body weight are supported by the cane and weaker leg)

Types:

46
Q

Is a wooden or metal staff needed to increase mobility

Types: double adjustable or forearm crutch and the axillary wooden or metal crutch

When these are fitted, ensure the length of the crutch is two to three finger widths from the axilla

Position the tips approximately 2 inches lateral and 4-6 inches anterior to the front of the patient’s shoes

Position the handgrips so the axillae are not supporting the patient’s body weight (Pressure on the axillae increases risk to underlying nerves, which sometimes results to partial paralysis of the arm)

Position of handgrips with the patient upright, supporting weight by the handgrips with the elbows slightly flexed at 20 – 25 degrees (Elbow flexion can be verified using goniometer)

Distance between the crutch pad and the axillae is approximately 2 inches (2 – 3 finger width)

Then have the patient move the left crutch forward and then move the right foot forward to the level of the left crutch

A

Four-point alternating

50
Q

Use of CRUTCHES

Gait requires the patient to bear all of the weight on one foot
Patient bears weight on both crutches and then on the uninvolved leg

Have the patient move the affected leg and both crutches forward about 12 inches.
Have the patient move the stronger leg forward to the level of the crutches

A

Three-point alternating

51
Q

Use of CRUTCHES

Gait requires at least partial weight on each foot
Patient moves a crutch at the same time as the opposing leg so the crutch movements are similar to arm motion during normal walking

Have the patient move the left crutch and the right foot forward about 12 inches at the same time.
Have the patient move the right crutch and left leg forward to the level of the left crutch at the same time.

A

Two-point alternating

52

A

Swing through

54
Q

it decreases work effort and places less strain on musculoskeletal structures during routine activities

A

Principles of safe patient transfer and positioning

55
Q

Principles of Safe Patient Transfer and Positioning

A

Mechanical lifts and lift teams are essential when a patient is unable to assist

When a patient is able to assist, remember the following principles:

The wider the base of support, the greater the stability of the nurse

The lower the center of gravity, the greater the stability of the nurse

The equilibrium of an object is maintained as long as the line of gravity passes through its base of support

Facing the direction of movement prevents abnormal twisting of the spine

Dividing the balance activity between arms and legs reduces the risk of back injury

Leverage, rolling, turning or pivoting requires less work than lifting

When friction is reduced between the object to be moved and the surface on which it is moved, less force is required to move it
