This program contains all of the components of work conditioning, but also gradually increases a client's physical and functional work tolerances for an 8-hour day. In addition to the components provided for work conditioning, there is a strong emphasis on work simulation. Specific return-to-work or retraining goals are set and the physical work demands of the goal(s) are simulated in our clinic. Program duration is 4 to 8 hours a day, daily for 4 weeks.
