What condition can result from prolonged use of power or air tools?

Back injury
Carpal tunnel syndrome
Tendinitis
Joint pain

The correct answer is: Carpal tunnel syndrome

Prolonged use of power or air tools can lead to carpal tunnel syndrome due to repetitive motion and pressure on the median nerve that runs through the wrist. This condition is characterized by symptoms such as numbness, tingling, and weakness in the hand and arm, often caused by extended periods of grip strength and vibration from the tools. The movements associated with power tools, such as gripping, twisting, and pushing, can place significant stress on the tendons and nerves in the wrist, which is why over time, these symptoms can develop. Occupational exposure to these tools, especially in jobs that require constant hand use, increases the risk of developing this syndrome. While conditions like back injury, tendinitis, and joint pain can also arise from tool usage—especially in conjunction with improper ergonomics—carpal tunnel syndrome specifically pinpoints the nerve entrapment caused by repetitive wrist activities common in power tool operation.
