a documented medical complication;
a need for additional treatment to assist the employee in the initial return-to-work where the employee's work activities place stress on the part of the body affected by the work injury;
treatment that continues to meet two of the following criteria documented by medical records:
an employee's subjective complaints are improving,
an employee's objective complaints are improving,
an employee's functional status is objectively improving;
an incapacitating exacerbation of the employee's condition.
