Safety & Environmental Management Video Display Terminal (VDT) Training MTM055 Dec 27, 04
Understanding Musculoskeletal Injury (MSI)
MSI = injury or disorder of the muscles, tendons, ligaments, joints, nerves, blood vessels, or related soft tissue, including sprains, strains, or inflammation that may be caused or aggravated by work.
MSI Risk Factors Forceful ExertionForceful Exertion Physical effort that places a high load on the muscles, tendons, ligaments, and joints Repetitive MotionRepetitive Motion Tasks that use the same muscle groups repeatedly Awkward PosturesAwkward Postures Working out of the neutral body position Static PosturesStatic Postures Body positions held without movement for more than 20 seconds Contact StressContact Stress When body parts come into contact with hard or sharp objects
Workstation Setup Eyestrain Lower back pain Neck pain Shoulder pain Elbow pain Wrist pain Poor positioning can contribute to : Cramped fingers Listen to your body
Cramping or spasm Tingling, pins and needles or numbness Heat or Burning Tenderness Pain Symptoms of MSI
Maine law states that if you work on a VDT for more than 4 hours a day, your employer must: train you to use your VDT and to avoid or minimize conditions that may arise from long or improper use train you on the importance of proper posture when you use a VDT and how to adjust your workstation to achieve proper posture. train you within the first month of your being hired and annually thereafter Workstation Setup
Body Position Hands, wrists, and forearms are straight, in- line and roughly parallel to the floor Elbows stay in close to the body and are bent between 90 and 120 degrees. Shoulders are relaxed and upper arms hang normally at the side of the body. Head is level, or bent slightly forward, forward facing, and balanced.
Body Position Feet are fully supported by floor or footrest. Knees are about the same height as the hips with the feet slightly forward. Back is fully supported with appropriate lumbar support when sitting vertical or leaning back slightly Thighs and hips are supported by a well- padded seat and generally parallel to the floor
Monitors Monitors should be placed directly in front (but not more than 35°) to the left or right The screen should be at least 20 away from your eyes and at right angles to window(s) to avoid glare The best distance is as far away as possible while still being able to read it clearly.
Monitors Keep the top line of the screen at eye level or slightly below to avoid neck strain Use document holders
Keyboard and Mouse Your wrists should be supported and in-line with your forearms Keep the mouse close to the keyboard Wrist rests Are only used to support the palms in between keying movements Should be fairly soft and should not be any higher than the front edge of your keyboard Should encourage neutral wrist posture Your wrists should not be deviated while typing
Chairs Seat height should be adjustable to allow your feet to rest flat on the floor (preferred) or on a footrest Backrest should provide lower back support Armrest should be adjusted so they support your lower arm and allow your upper arm to remain close to the torso Try out a chair – available at Central Supply/Purchasing
Workstation All other equipment (mouse, telephone, copy holder, etc.) should be positioned to prevent strain and discomfort from excessive reaching, bending and turning.
Telephones can be a Pain in the Neck Location / awkward reach Phone neck - gripping the telephone between shoulder and head Posture – leaning forward away from the back of the chair while taking a call Cell phones – awkward posture, finger and thumb strain from excessive text keying
Laptops... So Whats Wrong with Them? Portability vs. ergonomics Screens smaller Screen not independent of the keyboard Smaller keyboard, smaller keys Different key spacing and travel Mouse is awkward Uncomfortable neck or wrist position Furniture in hotel rooms, other offices, or home sometimes inadequate for laptop use Difficult to transport
Laptop Posture Sometimes a tradeoff between neck/head posture and hand/wrist posture Occasional User Position laptop in your lap for the most neutral wrist posture Angle the screen so that you can see it with the least amount of neck deviation
Laptop Posture Full Time User Position the laptop so that you can see the screen without bending the neck Use a separate keyboard and mouse Use the keyboard in a negative tilt to ensure a neutral wrist posture
Laptops... Suggestions Use external devices Keyboard and mouse Use commercially available laptop holders or laptop supports
Mobile Work Layout
Hotel/Conference Room/Café/etc. Use a pillow, pad, folded towels, or a blanket to raise your seat height Support your back (lumbar region) using a rolled up towel, clothing, pillow, etc. Try using a chair without armrests to give you more room to move your arms Using your lap is an option – look down at the screen by tucking your chin instead of bending your entire neck down
Breaks Operator should take regular breaks Vision and stretch breaks after 1 hours use of a desktop Vision and stretch breaks after 1/2 hours use of a laptop Micro breaks (30 seconds, every 10 minutes) Breaks can consist of performing other work tasks.
What Can You Take Away From This Training? Prevention is the most important strategy Dont wait to feel pain to start changing your habits Listen to your body You DONT have to be in pain to get your job done There are numerous ergonomic solutions to help keep you pain free Were always here to help
Thank You Dont forget to document your training. A certificate of training is available on the VDT Training web page at:
