Work-related musculoskeletal disorder is a condition that affect the muscles, tendons and nerves and is associated with following work patterns:

  • Fixed or constrained body positions
  • Continual repetition of movements
  • Force concentrated on small parts of the body, such as the hand or wrist.

The continual repetition and lack of time for recovery makes those ordinary activities hazardous. Heat, cold and vibration are other contributing factors.


The most common symptoms include: pain as well as a feeling of “pins and needles.”

MSDs tend to occur in stages:

  • Early: the affected body part may feel tired and achy during the work shift, but fine at night or on days off.
  • Middle: the aching pain and tiredness will start early in your workday and persist at night.
  • Late: You feel the pain even when at rest, and may have trouble performing light duties.

When you recognize a problem, even in an early stage, you should take action.


Workplace Design

Proper design of the workstation decreases the effort required of the worker to maintain a fixed position.

Tools and Equipment Design

Proper design of tools and equipment significantly decreases the force needed to complete the task.

Work Practices

The importance of rest periods should be emphasized. Take advantage of short periods of time between tasks to relax the muscles.


Restrict movement: Avoid the activities and tasks that cause the injury.

Work out: Stretching may be beneficial, as it promotes circulation and reduces muscle tension.

Use hot and cold remedies: Cold reduces pain and swelling and is recommended for injuries and inflammations. Heat is recommended for muscle pain relief.
