What type of injury results from excessive hand and wrist usage?

Repetitive stress injuries are specifically associated with the cumulative effects of repetitive motions or stress on the muscles, tendons, and nerves, particularly in areas like the hands and wrists. These injuries occur over time due to prolonged or excessive use of certain body parts, often seen in activities that require constant hand movements, such as typing or using a mouse.

This category of injuries can manifest in various forms, including tendonitis or carpal tunnel syndrome, which are directly linked to specific patterns of behavior in the workplace or during certain activities. Therefore, identifying them as repetitive stress injuries accurately describes the nature of the problem stemming from excessive hand and wrist usage, making it the correct answer.

The other options represent different concepts; joint injury could imply a singular trauma or condition affecting a joint rather than an outcome of repetitive actions. Acute injury typically refers to a sudden injury that happens instantaneously rather than developing over time. Chronic pain describes ongoing pain that persists over an extended period but does not specifically address the cause in relation to repetitive activities.
