Musculoskeletal Disorder (MSD) Prevention

Musculoskeletal disorders (MSDs) are increasing among workers. While these conditions were once common mainly in large manufacturing industries, they are now spreading to service workers and office employees.

 . 

 . 

Repetitive Motion Is the Main Cause

MSDs are functional disorders caused by the accumulation of micro-injuries in muscles and tissues due to excessive force, repetitive movements, and awkward working postures. They commonly affect the lower back, neck, shoulders, arms, and wrists.

 . 

These disorders account for nearly 70% of all occupational illnesses, making them a major workplace health issue.

 . 

According to industrial accident reports:

 . 

  • Repetitive motion: 58%
  • Awkward posture: 11%

 . 

If a worker repeats the same motion hundreds of times per hour, the body does not get enough recovery time. Over time, small injuries accumulate in muscles and ligaments. If this continues for more than six months, it may lead to chronic and irreversible conditions.

Excessive Computer Use as a Risk Factor

MSDs are also common among office workers. Typical examples include:

 . 

  • Forward head posture (Text neck syndrome)
  • Carpal tunnel syndrome

 . 

Studies show that about 70% of office workers sit for 7 to 11 hours a day and use computers for an average of 8.5 hours daily.

 . 

Poor posture and repetitive tasks can lead to pain in the neck, shoulders, and lower back.

 . 

Common risk factors include:

 . 

  • Typing and mouse overuse
  • Slouching posture
  • Prolonged screen viewing
  • Static positions for long periods

 .

Prevention Through Ergonomics and Stretching

Preventing MSDs requires effort from both employees and employers.

 . 

Workers should maintain proper posture, while employers should improve the workplace using ergonomic principles. Activities such as stretching, strength training, and workplace exercise programs can significantly reduce risks.

 . 

Stretching key joints—such as the neck, shoulders, elbows, wrists, and lower back—helps relieve muscle tension and improves blood circulation.

 . 

Office workers should especially focus on:

 . 

  • Regular walking
  • Daily stretching
  • Maintaining proper posture
