What is Body Mechanics?
The field of physiology that studies muscular actions and the function of muscles in maintaining body posture
Knowledge gained from such studies is especially important in the prevention of injury during tasks that require lifting and moving.
Why is Body Mechanics important?
Prevention of injury during lifting and moving tasks
Understanding body mechanics helps in performing tasks safely.
What percentage of the population has back problems by age 30?
30%
This statistic highlights the prevalence of back issues in the general population.
In healthcare, where do most injuries occur?
At the bedside
This indicates the high-risk environment for healthcare workers.
What is the Centre of Gravity?
Body balance achieved when the centre of gravity is balanced over a stable base of support
Proper posture enhances this balance.
Define Line of Gravity.
An imaginary line that extends from the centre of gravity to the base of support
It is essential for maintaining balance.
What is the Base of Support?
A bottom support; that on which a thing stands or rests
A stable base is crucial for maintaining balance.
What does Balance refer to?
A normal state of physiologic equilibrium
Balance is essential for safe movement and posture.
What is Weight Bearing?
The ability to resist weight or force through the bones, joints, and associated structures
Important for maintaining bone health.
List the principles of Body Mechanics.
- Maintain Body Balance
- Increase Stability
- Maintain Body Alignment
These principles help prevent injuries and ensure safe movement.
How can you increase stability?
- Maintain a wide base of support
- Spread feet apart
- Flex knees to move center of gravity
A wider base of support provides greater stability.
What does Body Alignment refer to?
The arrangement of joints, tendons, ligaments, and muscles while in standing, sitting, or lying positions
Proper alignment enables efficient movement and decreases strain.
What are the risk factors for back injuries?
- Lifting with back bowed or flexed
- Slouched sitting
- Twisting or jerking movements
- Lack of proper rest
- Obesity and poor nutrition
These factors increase the likelihood of sustaining an injury.
What should you do before lifting a load?
Always assess the load first
Understanding the load is crucial for safe lifting.
What are the types of Mobility Aids?
- Canes
- Walkers
- Crutches
- Wheelchairs
Each type serves different mobility needs.
What is the proper handle height for canes and walkers?
Should be adjusted to the user’s height
Proper fitting is essential for safety and effectiveness.
What should you check for in mobility aids?
- Secure adjustment pins and collars
- Check cane ends
- Ensure brakes are functional
Regular safety checks prevent accidents.
When using a cane, where should the tip be placed?
6-8 inches out to side and a bit forward from feet
This positioning aids in balance and support.
What is the correct order for stairs when using mobility aids?
- Good/strong leg goes up first
- Bad/weak leg goes down first
This technique ensures safety while navigating stairs.
What is the purpose of a wheelchair cushion?
To maintain position for skin integrity and comfort
Proper cushioning prevents pressure sores.
What should you do when portering a wheelchair?
- Move backwards over uneven terrain
- Stay on downhill side of wheelchair
These practices ensure safety for both the client and the porter.
