Principle 1

Principle 1

Work in Neutral Postures






Summary neutral postures
Summary — Neutral Postures

Neck straight

Shoulders relaxed

Elbows at sides

Wrists in neutral

Back with S-curve


Point
Point:

  • To work smarter, work in neutral postures

  • Evaluate and modify:

    • work method

    • tools

    • workstation design


Principle 2

Principle 2

Reduce Excessive Force


Point1
Point:

  • Think of what you do.

  • Think of ways to reduce excessive force.

  • Thousands of ways, only some examples here.


Principle 3

Principle 3

Keep Everything in Easy Reach



Principle 4

Principle 4

Work at Proper Heights

Most work at

elbow height

(sitting or standing)

Cumulative trauma disorders ctds

Cumulative Trauma Disorders (CTDs)

“Wear and tear” that accumulates thru time


Symptoms
Symptoms

  • Soreness, pain, discomfort

  • Numbness or burning

  • “Pins and needles”

  • Limited range of motion

  • Weakness and clumsiness
