Repetitive Motion Injuries

A repetitive motion injury occurs when the muscles, ligaments, tendons, or nerves are damaged because an individual repeatedly performs the same motion. Repetitive motion conditions manifest from many microscopic tears in the tissue. Generally, the body will self-heal these tiny tears as they occur. However, if the body cannot heal the tears because they are happening too often, inflammation and a potential repetitive stress injury can result. Depending on how serious the injury is, repetitive motion injuries can result in permanent damage.

Did You Know? The Bureau of Labor Statistics reports that the two most common types of repetitive stress injuries are tendonitis and bursitis.

What Is Tendonitis?

Tendons are tough, flexible, fibrous bands of tissue that connect muscles to bones. When inflammation, tears, or irritation occurs, the resulting condition is known as tendonitis. Tendons can be small, like the tiny bands in the hands, or large – such as thigh muscles. Tendonitis often occurs without knowing the exact root cause. It is most often due to overuse, or when a motion is repeated too often. This type of workplace injury can occur on an assembly line or as a result of too much time on a keyboard.

What Is Bursitis?

A bursa is a membrane near a joint that acts as a cushion between the muscle and bone. The bursa decreases friction caused by repetitive movement and increases joint flexibility. Bursitis is merely inflammation of a bursa. Bursitis is common, affecting those who overuse a joint in repetitive motion, such as a house painter. Bursitis is typically seen more often in those who are overweight, elderly, or diabetic.
