The two most common types of cumulative traumas are carpal tunnel syndrome (CTS) and injuries to the low back, but there are many other types as well. There is not usually much confusion as to the “date of injury” for a specific injury. However, the results can be all over the map, when trying to pin down the “date of injury” for a cumulative trauma. As stated above, Labor Code § 3208.1 states that the date of a cumulative trauma injury shall be determined in accordance with Labor Code § 5412 that provides as follows:
“The date of injury in cases of occupational diseases or cumulative injuries is that date upon which the employee first suffered disability there from and either knew, or in the exercise of reasonable diligence should have known, that such disability was caused by his present or prior employment.”
