  2. 2. DEFINITON OF POSTURE The word "posture" comes from the Latin verb "ponere" which is defined as "to put or place." The general concept of human posture refers to "the carriage of the body as a whole, the attitude of the body, or the position of the limbs (the arms and legs). Sometimes these injuries are referred to as “Cumulative Trauma Disorders” (CTDs), “Repetitive Strain Injuries” (RSIs) or Musculo Skeletal Disorders(MSDs).
  3. 3. ERGONOMICS Ergonomics literally means “the laws of work”. OSHA defines ergonomics as the science of “designing the job to fit the worker, instead of forcing the worker to fit the job.”
  4. 4. AM I AT RISK FOR A MSD Do you????  Perform frequent repetitive motions?  Bend at the waist or twist when lifting objects?  Lift push or pull objects throughout the day?  Sometimes use the wrong tool for the job?  Grasp tools with your fingers?  Forget to take breaks while working?  Feel like you are under stress?  Have to stretch to reach your work?  Forget to adjust your work area to fit your task? The more you answered “yes”, the greater your risk
  5. 5. RISK FACTORS THAT LEAD TO MSD Awkward posture Static loading or sustained exertion Contact stress Force Vibration Repetition of same motion for several hours/day Length of tasks without breaks Insufficient rest time Psychosocial stress
  6. 6. SOCIAL AFFECT  Decrease Health & Quality of life  Loss of self worth and fear of future  Psychosocial consequences, e.g., anxiety, stress & depression  Decrease Community involvement  Decrease Recreational activities
  7. 7. ECONOMIC AFFECT  Lost wages  Absenteeism (Mean 18 days)  Medical costs ($ 7000-30,000 per person)  Recruiting and training new staff  Retraining injured workers  Decrease Productivity & quality  Compensation
  8. 8. SYMPTOMS OF MSDS Discomfort Numbness LossTingling of strength Pain Swelling Reduced range of motion Fatigue Stiffness Aching
  9. 9. 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
  10. 10. PREVENTIONS They are preventable and reversible if identified early. The treatment depends on the stage of MSD. If the condition cannot be reversed, treatment can turn into a pain management situation. The individual plays a large role in preventing MSD’s.

  38. 38. BREAKS IDEAS Eye breaks - blink to moisten eyes every 5-10 minutes. Every 15 minutes or so look away from the screen to distant part of room. Micro-breaks - between burst of activity rest the hands, neck and shoulders in a relaxed straight posture. Rest breaks - every 30-60 minutes take a brief 5-minute break and engage in another activity. Exercise breaks - every 1-2 hours do gentle stretching exercises
  39. 39. STRETCHES & BREAKS Static positions are your enemy! Whenever you think of it, change position Small frequent stretches go a long way in preventing MSD’s.
