Repetitive Strain Injuries

Throughout the year, your union raises awareness about the devastating impact that Repetitive Strain Injuries can have.

Learn more about common type of RSIs that often affect workers. Together, help us raise awareness and ensure health and safe workplaces for all.

If you are experiencing the symptoms of an RSI that is related to your work, it is important that you notify your employer and a member of your workplace Joint Health and Safety Committee as soon as you recognize symptoms. Also see a health care professional to determine if accommodations or modifications to your work may prevent further injury.

Thoracic Outlet Syndrome

Thoracic Outlet Syndrome is a condition that occurs when the nerves that run between your lower neck and first rib become compressed. Some of the activities that cause this condition are poor repetitive movements like typing on a computer, poor posture, lifting items above head level, or working on an assembly line in a plant or factory. Some of the symptoms of Thoracic Outlet syndrome include pain in the shoulders and neck and numbness in the fingers.

Bursitis

Bursitis is a condition that affects your bursae which are small, fluid-filled sacs that cushion the body’s joints. It predominately affects the shoulders, the knees, the hips, elbows, and hips because of over use. Bursitis tends to be more painful while the joint is in use, but also causes pain while at rest.

Carpal Tunnel Syndrome

Carpal Tunnel Syndrome occurs when excess pressure is exerted on the median nerve which which travels down the arm and through the wrist. This nerve is responsible for sensation and controls movement in the thumb and first three fingers. Repeated hand and wrist movements, such as those made by cashiers, can increase the sensitivity of the median nerve and result in a tingling sensation, weakness and pain.

De Quervain's Disease

De Quervain's Disease results in swelling and pain from the lower arm to the base of the thumb due to the inflammation of the tunnel that contains the two tendons that control the movement of the thumb. It often affects your ability to grip objects. De Quervain’s Disease can be caused by tasks or jobs that rely on hand or wrist motions that are repetitive.

Tendonitis 

When the tendons in your body are overused, they become swollen due to inflammation and painful tears. The condition generally occurs in your hands, shoulders or elbow. As a result, you may experience pain and lack of mobility which gradually increases if not treated.
