Yes, repetitive stress injuries resulting from a job may be covered as workplace injuries in most cases. Examples of these injuries include carpal tunnel syndrome or damage to your back or knees resulting from repetitive lifting at work.
It will often be required that you prove that an injury was caused by your specific job duties. This means that if you develop carpal tunnel syndrome, but you engaged in frequent, repetitive movements with your hands outside the workplace such as typing or using a keyboard at home or you have a family history of carpal tunnel syndrome, your employer could argue your injury was the result of those conditions rather than your job.
Such denials are usually not valid, but employers are willing to use anything to deny a workers’ compensation claim. Medical testing will be important for confirming a repetitive motion injury.
