what are the benefits of ergonomics

YOU JUST FEEL BETTER!

What are the benefits of ergonomics?
  • Reduction of work-related injuries
  • Increased worker productivity
  • Increased work quality
  • Reduced absenteeism
  • Increased morale
  • Ergonomics provides a win-win situation…..on and off the job

who s at risk
Who’s At Risk?
  • Nearly everyone, but women report more incidents of discomfort
  • Low motivation
  • Poor workstation design
  • Pregnant
  • Obese
  • Lack general physical capabilities, such as strength
  • People who feel as if they lack control over work pace, environment, and communication

Working in awkward postures / positions

Prolonged sitting and standing

Bending, reaching, stretching

Driving for extended periods of time

Heavy lifting

Awkward lifting

Lifting in combination with twisting

Pushing, pulling, carrying

Accidents, slips, trips, falls

Vibration

resulting injuries are called
RESULTING INJURIES ARE CALLED:

Queries- Mob: 800 845 2222, prabhat.lakki@gmail.com

  • Cumulative Trauma Disorders(CTD),

Or

  • Repetitive Strain Injuries(RSI),

Or

  • Musculoskeletal Disorders(MSD)
what two elements are at work
What two elements are at work?

2) Dynamic work

  • Static work: musculoskeletal effort required to hold a certain position, even a comfortable one.

Example: sit & work at computers; keeping head and torso upright requires small or great amounts of static work depending on the efficiency of the body positions we chose.

Muscles fatigue faster when they are held in one position.

Static muscle contraction

Muscle tense

Blood flow is reduced INJURY/ DISABILITY

Muscle nutrition is reduced Muscle Pain & fatigue

Waste products (lactic acid) build up

Queries- Mob: 800 845 2222, prabhat.lakki@gmail.com

  • Key issue is recovery time

- the time required for tissue to restore nutrition, replace cells, dissipate byproducts

- rest breaks

  • Some newer research demonstrates that repetition

is significantly less of a problem vs. posture

symptoms of msd

adaptation vs injury the fork in the road
Adaptation vs. Injurythe fork in the road…
  • Adapt
    • Soft tissue remodels
    • More strength
    • More stability
    • More endurance
    • Discomfort decreases
  • Injury
    • Soft tissue breaks down
    • Less strength
    • Less stability
    • Less tolerance for use
    • Discomfort increases

MORE FREQUENTLY OCCURRING OCCUPATIONALLY INDUCED DISORDERS:

Hand problems-

  • nerve pinch or nerve entrapment
  • Triggering of fingers

Neck and back problems

  • Spondylitis
  • Tingling in fingers and toes

Knee problems

  • Meniscal tear
  • Cartilage damage
  • ACL rupture

carpal tunnel syndrome one of the best known msds

OUCH!

CARPAL TUNNEL SYNDROMEOne of the best known MSDs

Numbness is usually first symptom.

The median nerve does not work properly due to pressure on the nerve as it runs through an opening called the carpel tunnel

Pain & tingling, can go up the arm to the shoulder and neck, causing waking to pain in middle of night

Queries- Mob: 800 845 2222, prabhat.lakki@gmail.com

guyon s canal syndrome similar to carpel tunnel

OUCH!

GUYON’S CANAL SYNDROMESimilar to carpel tunnel

Guyon’s affects the ulnar nerve as it passes through the Guyon canal in the wrist; this is similar to carpal tunnel, but involves a different nerve.

Unlike carpel tunnel, Guyon’s affects the little and ring fingers.

Can be in conjunction with carpal tunnel

trigger finger

CLICK!

OUCH!

TRIGGER FINGER

Trigger finger affects the ability of tendons to slip back and forth. The tendon and/or ligament thicken and a nodule forms

This can be caused by rheumatoid arthritis, lacerations of tendon, gripping power tools, long hours of grasping steering wheel, or birth defects

Symptoms are pain and

a funny clicking sensation

tennis elbow

OUCH!

TENNIS ELBOW

Overuse or misuse of the forearm muscles can cause tendonitis, or a painful inflammation of the tendons connecting these muscles to bone.

This condition is brought

on or aggravated by poor leverage

causing an uneven distribution

of force on a few muscles.

This may be when working,

or during certain leisure activities,

such as sports and gardening.

Symptom are severe pain.
