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 YOU JUST FEEL BETTER! Queries- Mob: ,
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 Queries- Mob: , 4
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 Job Risk Factors Queries- Mob: ,
RESULTING INJURIES ARE CALLED: Cumulative Trauma Disorders (CTD), Or Repetitive Strain Injuries (RSI), Or Musculoskeletal Disorders (MSD) Queries- Mob: ,
2) Dynamic work What two elements are at work? 1)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. Queries- Mob: ,
Static muscle contraction Muscle tense Blood flow is reduced INJURY/ DISABILITY Muscle nutrition is reduced Muscle Pain & fatigue Waste products (lactic acid) build up How injuries occur? Queries- Mob: ,
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 A word on repetition Queries- Mob: ,
SYMPTOMS OF MSD Muscle fatigue or pain Aching Burning Numbness Stiffness Tingling Queries- Mob: ,
SIGNS OF MSD Decreased range of motion Loss of function Deformity Cramping Loss of color Decreased grip strength Loss of balance Swelling Redness Queries- Mob: ,
Adaptation vs. Injury the 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 French & Zecha, 2005 Queries- Mob: ,
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 Queries- Mob: ,
CARPAL TUNNEL SYNDROME One of the best known MSDs The median nerve does not work properly due to pressure on the nerve as it runs through an opening called the carpel tunnel Numbness is usually first symptom. Pain & tingling, can go up the arm to the shoulder and neck, causing waking to pain in middle of night Queries- Mob: ,
GUYON ’ S CANAL SYNDROME Similar 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 Queries- Mob: ,
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 Queries- Mob: ,
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. Queries- Mob: ,
