Microscopy
Operating a microscope for long hours puts much strain on the neck, shoulders, eyes, lower back, and arms/wrists.
Associated Risk Factors:
- Awkward and static posture of the lower back
- Lack of adequate leg and knee clearance under work table
- Working with elbows winged
- Pinch grip when adjusting binocular eyepiece
- Wrist and palm contact pressure in the carpal tunnel area
- High repetition
- Eye strain and fatigue
- Awkward and static posture of the neck and head
Preventive Measures:
- Do not work with elbows winged. Keep elbows close to sides, below 45-degree angle.
- Make sure to work with wrists in neutral (straight) position. Avoid forearm and wrist contact pressure. Pad sharp edges with foam, or pad wrists and forearms to reduce pressure.
- Ensure that feet are flat on floor or supported by footrest.
- Avoid raising shoulders and bending neck while looking through microscope's eyepiece.
- Position microscope as close as possible towards you to ensure upright head position.
- Use or purchase extended eyetube and/or variable height adapter to achieve proper neck and head position.
- Prevent repetition, and alter prolonged awkward posture. Take adequate small breaks, or perform other job tasks that require less repetition, rest your eyes, neck, and shoulders.
- Make sure scopes remain clean all the time, and lighting is of properintensity.
- Use a fully adjustable ergo-task chair or stool with built-in solid footrest.
- Adjust the eyepieces and angle of observation to prevent neck strain. Use adjustable microscope stands.
- Use proper sitting posture and positioning.
- Take stretch breaks and rotate tasks.
- Use lifters and angled microscope arm supports to relieve fatigue and strain.
- Ensure that sufficient knee and leg space is available.
- Use television systems to eliminate the use of binocular eyepieces when appropriate.
