(a)          for an average of at least 8 hours per week; and
(b)           for a cumulative period of at least 6 months before the clinical onset of carpal tunnel syndrome; and
if those activities have ceased before the clinical onset of carpal tunnel syndrome, then that onset occurred within 30 days of cessation;
            Note: specified activities with the affected hand or forearm is defined in the Schedule 1 - Dictionary.
(2)          having trauma or surgery to the affected wrist or hand before the clinical onset of carpal tunnel syndrome, which:
(a)          alters the normal contour of the carpal tunnel; or
(b)          damages the flexor tendons within the carpal tunnel;
Note: trauma to the affected wrist or hand is defined in the Schedule 1 - Dictionary.
(3)          having oedema involving the affected carpal tunnel at the time of the clinical onset of carpal tunnel syndrome;
            Note: Examples of situations in which oedema involving the affected carpal tunnel may occur include external burn, fracture, lymphoedema and animal envenomation.
(4)          being overweight or obese at the time of the clinical onset of carpal tunnel syndrome;
Note: being overweight or obese is defined in the Schedule 1 - Dictionary.
