Ergonomics


Definition

Definition

  • The science of matching jobs, systems, products and environments to the capabilities and limitations of the worker. - textbook

  • The study of designing equipment and devices that fit the human body, its movements, and its cognitive abilities - wikipedia


Ergonomics1

Ergonomics

  • Ergonomic Designs ideally allow the joints to be in a NEUTRAL POSITION in which ligaments or tendons are not pulling on bones or other muscles, when the object is being handled.


Soft tissue injuries

Soft Tissue Injuries

  • An injury of the muscles, tendons, ligaments, joints, nerves, blood vessels, or related structures – textbook

  • Refers to muscles, tendons, ligaments and skin but not bones or internal organs


Examples of soft tissues injuries

Examples of Soft Tissues Injuries

  • Strains (pulled muscle)

  • Sprains (overstretched ligament)

  • Tendonitis (inflammation of tendon)

  • Tennis Elbow

  • Carpal Tunnel Syndrome


Terms

Terms

  • Ligaments attach bone to bone

  • Tendons attach muscle to bone

  • Muscles contract, moving bones they are attached to by ligaments. Other bones may also move if they are attached by tendons.

Carpal tunnel syndrome

Carpal Tunnel Syndrome


Causes

Causes

  • Repetitive movements

  • Sudden forceful movements

  • Constant or awkward posture

  • Strain from use of improper leverage when lifting

  • Not properly warming up or cooling down before strenuous activity


Signs of soft tissue injury

Signs of Soft Tissue Injury

  • Numbness

  • Tingling or Burning sensations

  • Pain/Tenderness

  • Swelling

  • Redness

  • Restricted movement Loss of strength


Poor positioning causes strain on tendons and ligaments

Poor Positioning Causes Strain on Tendons and Ligaments


Carrying loads improperly can cause shoulder injuries

Carrying Loads Improperly can cause Shoulder Injuries


Improper lifting can cause injury

Improper Lifting can cause Injury


Proper lifting technique

Proper Lifting Technique


Neutral postures

Neutral Postures

  • When joints are at under minimal strain and at their strongest point

  • When joints move away from the neutral posture, strain on tendons, muscles etc. increases and strength decreases.

  • Neutral postures reduce strain and keep joints in a “safe zone” where they can avoid injury.

Healing phases

Healing Phases

  • Reaction or Inflammatory Phase – marked by pain, swelling, redness, and increased temperature. Can last approx 72 hours.

  • Formation of Scar Tissue or Collagen – lasts 48 hours to six weeks

  • Replication – Replacement of damaged tissue can take from 6 weeks to a year
