Musculoskeletal Disorders (MSD) are injuries or disorders of muscles, nerves, tendons, joints, cartilage, or spinal discs.
MSD are considered work-related when the work activities and work conditions significantly contribute to their development or exacerbation but are not the sole determinant of causation (World Health Organization, 1985).
- Repetitive or awkward hand movements
- “Static loading” or holding a posture
- Poor muscle endurance
- Direct mechanical pressure on tissues
- Basic workstation design
- Low temperature of the environment
Early warning signs and symptoms
- Discomfort and fatigue
- Swelling or any change in the limb’s temperature
- “Catching” or “snapping” with movement
- Loss of grip strength
- Numbness and tingling
- Visual strain
The injury accumulates slowly leading to difficulty in day-to day activities such as shaking hands, opening doors, holding newspapers, using a comb, or even holding a teacup.
