Key Takeaways

  • Lift with legs, not back - bend at knees and hips, keep back straight
  • Keep loads close to your body to reduce strain
  • Never twist while lifting - move your feet to turn
  • Use gait belts, mechanical lifts, and other equipment when available
  • Ask for help when needed - teamwork prevents injuries

Body Mechanics and Safe Lifting

Body mechanics is the proper use of your body to prevent injury during movement and lifting. CNAs frequently move, lift, and transfer patients, making good body mechanics essential for career longevity.

Why Body Mechanics Matter

  • Back injuries are the most common CNA injury
  • Improper lifting can cause permanent damage
  • Good habits protect you throughout your career
  • Poor mechanics also put patients at risk

Principles of Body Mechanics

PrincipleApplication
Wide base of supportStand with feet shoulder-width apart
Low center of gravityBend at knees and hips, not waist
Keep load closeHold objects/patients close to your body
Use legsLift with leg muscles, not back
Avoid twistingMove your feet to turn, don't twist spine
Maintain alignmentKeep back straight, ears over shoulders over hips
Know your limitsGet help when needed

Safe Lifting Techniques

Before lifting:

  1. Assess the load - can you lift it safely?
  2. Clear the path - remove obstacles
  3. Get help if needed - don't be a hero
  4. Plan the move - know your destination

During lifting:

StepAction
1Stand close to the object/patient
2Widen your base of support
3Bend at the knees and hips
4Keep your back straight
5Tighten abdominal muscles
6Grasp the load securely
7Lift with your legs
8Keep the load close to your body
9Move smoothly - no jerking
10To turn, move your feet - don't twist

Common Mistakes to Avoid

MistakeWhy It's DangerousCorrect Action
Bending at waistStrains back musclesBend at knees and hips
Twisting while liftingDamages spinal discsMove feet to turn
Reaching outCreates leverage strainKeep load close
Lifting aloneExceeds safe limitsAsk for help
RushingLeads to improper formTake your time
Not locking equipmentEquipment can moveAlways lock wheels

Ergonomic Equipment

Use available equipment to reduce injury risk:

EquipmentUse
Mechanical liftDependent patients, heavy patients
Gait beltTransfers, ambulation assistance
Slide boardLateral transfers
Slide sheetRepositioning in bed
WheelchairTransport
Draw sheetRepositioning, turning
Adjustable bedsRaise to comfortable working height

Using a Gait Belt

The gait belt (transfer belt) is essential for safe transfers:

StepAction
1Apply belt around patient's waist (over clothing)
2Secure snugly - can fit 2 fingers underneath
3Position buckle to front or side (not over spine)
4Grasp belt at patient's sides with underhand grip
5Stay close to patient during transfer
6Remove after transfer is complete

Never use gait belt:

  • On recent abdominal surgery patients
  • On patients with feeding tubes at waist level
  • On patients with severe osteoporosis
  • On pregnant patients
  • When contraindicated by care plan

Safe Patient Transfers

Basic transfer steps:

  1. Prepare environment - Lock bed/wheelchair, clear path
  2. Prepare patient - Explain procedure, proper footwear
  3. Position patient - Sitting on edge of bed, feet on floor
  4. Apply gait belt - If used
  5. Block patient's knees - With your knees if needed
  6. Help patient stand - On count of 3
  7. Pivot together - Move feet, don't twist
  8. Lower patient - Bend your knees
  9. Position comfortably - Adjust as needed

Repositioning in Bed

Using draw sheet method:

  1. Lower head of bed flat (if tolerated)
  2. Two staff members on opposite sides
  3. Fanfold draw sheet close to patient
  4. On count of 3, lift and slide toward head
  5. Use body weight shifting (not back)
  6. Reposition pillows as needed

Protecting Yourself

StrategyApplication
Stay fitStrong core muscles protect back
StretchBefore and after shift
Report injuriesEven minor strains
