  • 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.








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






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
