- Ergonomics
- The science of designing workspaces and tools to fit the physical needs of the user, reducing strain and injury risk.
- Musculoskeletal Disorder (MSD)
- An injury or pain affecting muscles, tendons, nerves, or joints β typically caused by repetitive motion, poor posture, or sustained awkward positions.
- Neutral Posture
- A body position in which joints are naturally aligned and muscles are under minimal stress β the target posture for any ergonomic setup.
- Lumbar Support
- A chair feature or accessory that supports the natural inward curve of the lower spine, reducing lower back strain during prolonged sitting.
- Viewing Distance
- The horizontal distance between the user's eyes and the monitor screen, typically recommended at 50β70 cm for standard displays.
- Document Holder
- A stand or clip positioned adjacent to the monitor to hold reference materials at eye level, reducing repeated neck rotation.
- Corrective Action
- A specific, documented step taken to fix an identified ergonomic deficiency β such as raising a monitor or replacing a chair.
- Repetitive Strain Injury (RSI)
- Cumulative damage to muscles, tendons, or nerves caused by repeated identical movements, commonly affecting wrists, shoulders, and elbows in office workers.
- OSHA General Duty Clause
- A US federal requirement (Section 5(a)(1) of the OSH Act) that employers provide a workplace free from recognized hazards, which courts and OSHA inspectors have applied to ergonomic risks.
- Workstation Assessment
- A structured review of a single employee's work environment to identify physical risk factors and document recommended adjustments.
