Each person has physical limits, or a “comfort zone,” of activities and work levels they can tolerate without developing symptoms of MSDs. Some factors which may contribute to MSD symptoms include:
- Furniture designs or a work area arrangement which produces bad postures.
- Physically demanding work which employees are not accustomed to doing.
- Workers who are generally out of shape.
- Underlying arthritis.
- Diminished muscle strength or joint flexibility.
