Work-Related Repetitive Motion Injuries

Repetitive motion injuries, also called repetitive strain injuries, overuse syndromes, and cumulative trauma disorders, are temporary or permanent injuries to muscles, nerves, ligaments, and tendons caused by performing the same motion repeatedly. In addition to pain, other common symptoms can include swelling, tingling, numbness, stiffness, weakness, and sensitivity to cold or heat. Most common examples of repetitive motion injuries include:

• carpal tunnel syndrome
  
• tendonitis, and
• bursitis​

Even if you are experiencing mild discomfort or pain, you should be evaluated to modify your work activities and environment to prevent further injury. You can minimize your risk of repetitive motion injury by educating yourself on proper positioning (i.e., sitting, standing, bending). Every employer should be familiar with federal laws and guidelines that require employers to try to prevent repetitive motion injuries.

​Repetitive motion injuries can be worsened by various work conditions, including computer use. A construction worker who uses vibrating power tools and works outside during the winter may be more prone to injury due to exposure to cold and vibration. People with small wrists, particularly females, may be more prone to repetitive motion injuries due to limited space within the wrist once swelling occurs.

Mild cases of repetitive motion injuries are treated conservatively with rest, icing, splinting, and elevation. Anti-inflammatory oral medications or steroid injections may also be used. Surgical treatment may be an option when the injury is moderate to severe or causing significant functional impairment.
