What is ergonomics? |
the science of fitting the task to the worker in order to decrease stress, and increase worker productivity, comfort and safety |
|
|
what are the different types of risks? |
physical- intensity/magnitude of force, duration/repetition, extreme temperatures, and vibration psychosocial- worker dissatisfaction, unfamiliar work tasks or environment, pace of work (work against a machine, time or coworkers), unsympathetic cow-workers/management |
|
|
how can risk be reduced? |
through 2 different types of controls : engineering- protection (safety equipment), prevention (changes to work stations, adaptations to tools) administrative- work practice (mandatory personal safety equipment), training and education (fitness, proper work techniques), workload changes (duration and frequency), policies and procedures (return to work programs) and health/safety committees |

Explain musculoskeletal disorder pain |
Musculoskeletal pain is pain that affects the muscles, ligaments and tendons, and bones. There is 3 stages: early stage- pain may disappear after a rest away from work intermediate stage- body part aches and feels weak soon after starting work and lasts until well after shift advanced stage: body part aches and feels weak even at rest, sleep is affected, light tasks are difficult on days off

Explain Hand-Arm Vibration Syndrome (HAVS) |
A vascular, neurological and musculoskeletal syndrome caused by prolonged exposure to vibration. Presentation: vascular- white fingers, cold sensitivity, extreme sweating neurological- numbness/tingling and reduced sensation Muscular- reduced grip strength Skeletal- bone cysts ADL complaints: cold sensitivity, writing, picking up small objects, opening lids and packages, lifting and carrying Treatment: -decreased vibration exposure (micro breaks, antivibration gloves) -lighter grip on machine -task rotation -stop smoking |

|
What are the roles of occupational therapy in ergonomics? |
-treatment of acute, subacute and chronic conditions -return to work planning and training -pain management -job site visits -functional abilities evaluation |
|
|
Explain the functional abilities evaluation and what are the components of an FAE? |
it is an assessment to assess the workers ability to return to their specific job or can be non specific which would assess their general abilities and medical limitations 2 main components: Written evaluation- includes history, VAS for pain and self perception of ability testing- standardized lift and carry, sustained grip and pinch, other standardized assessments, endurance testing, work stimulation |
|
|
what are the different levels of physical demand? |
sedentary work- involves exerting up to 10 lbs occasionally (1/3 of the time) and sitting most of the time light work- involves exerting up to 20 lbs occasionally and or up to 10 lbs frequently, requires standing and sitting but pushing or pulling of arm/leg controls or working at a production rate pace medium work- exerting 20-50 lbs occasionally, 10-25 lbs frequently and or up to 10 lbs constantly heavy work- exerting 50-100 lbs occasionally, 25-50 lbs frequently, and 10-20 lbs constantly very heavy work- exerting 100+ lbs occasionally, 50 lbs frequently, and an excess of 20 lbs constantly occasional is defined as 1-3 hours frequent is defined as 3-6 hours constant is defined as 6-8 hours |

|
explain some of the false beliefs about RTW |
- people must do 100% of their job tasks before RTW - people who are injured need total rest in order to recover - most people want to stay off work as long as possible - light duty is an effective way to return people to their full activities |
