We utilize various methods and techniques based on research
and published best practices, including:
- User observation and surveying
- User centered product testing
- Time study and work sampling methods
- Ergonomic criteria development and critique
- Biomechanical modeling
- Physiological modeling
- Repetitive lifting analysis
- Anthropometry measurement and calculation
- Direct measurement
|
When necessary, we utilize sophisticated equipment and
techniques to quantify worker biofeedback (e.g., bodily
responses) and workplace factors, including:
- Electromyography (EMG): To identify muscle use,
relative effort levels, and fatigue potential
- Electrogoniometry: To identify postural deviations
or non-neutral postures, and motion patterns
- Heart rate monitoring: To identify heart rate elevations
to estimate physiological demand or cost of work
- Lumbar Motion Monitor (LMM): To identify 3D back
postures and motion
- Pressure mapping: To identify pressure and force
levels, distributions, and patterns
- Vibration/shock: To identify random oscillation
or impulse magnitudes imposed on the hand-arm or whole
body
- Heat stress monitoring: To identify thermal environmental
factors and worker exposure
- Noise monitoring/dosimetry: To identify sound levels
and exposure to the ambient environment or specific
source
- Illumination monitoring: To identify light levels
and uniformity ratios relative to existing fixtures
and layouts
