Repetitive strain injury

A musculoskeletal disorder caused or aggravated by repeated movements, sustained awkward postures, or forceful activity. It commonly affects the hands, wrists, arms, and shoulders.

Tendon: A tough band of connective tissue that attaches muscle to bone and transmits force. Tendons can become irritated when repetitive loading outpaces their recovery.
Workplace health and safety: The policies and practices used to prevent injury and illness in workplaces. Workplace controls address task demands that can cause or worsen repetitive strain injury.
Carpal tunnel syndrome: A condition caused by compression of the median nerve as it passes through the wrist's carpal tunnel. Unlike the broad injury label, this is a specific diagnosis with a defined nerve-compression mechanism.
Work-related musculoskeletal disorder: A musculoskeletal condition caused or aggravated by workplace exposures and task demands. This broader category frames debates over how much work contributes to particular symptoms.
De Quervain syndrome: A painful disorder involving the tendons on the thumb side of the wrist. It is a localized tendon condition that may be associated with repetitive hand use.
Tendinopathy: A tendon disorder involving pain and impaired function, often associated with repeated loading. This is a common tendon-related form of repetitive strain injury.
Occupational health: The field concerned with protecting and improving health in relation to work. Occupational health professionals assess work exposures and support prevention and recovery.
Arthritis: A group of disorders involving inflammation or damage in joints, often causing pain and stiffness. Joint disease can resemble repetitive strain injury symptoms but has a different underlying source.
Pain: An unpleasant sensory and emotional experience associated with actual or potential tissue damage. Pain severity does not map neatly onto visible tissue changes or a single workplace exposure.
Lateral epicondylitis: Painful tendinopathy affecting the outer side of the elbow, often called tennis elbow. Repetitive gripping and wrist extension can contribute to this specific elbow disorder.
