The purpose of this study was to investigate the effectiveness of a 12-week work hardening program designed for back injured workers.
In this study, 32 subjects were recruited. Pre- and post-assessment results were used to measure the program effectiveness. The intensity of the work hardening program was based on the overloading training principle. Subjects were contacted by phone three months after the program completion for their work status.
The findings of this study suggested that there was a significant difference in the subjects' physical demand characteristic level before and after the work hardening program. Seventy-five percent of the subjects who completed the work hardening program were able to resume employment.
The rate of returning to work for back injured workers in this study was comparable to that of other studies. Thus, this study suggests that the overloading principle should be used in designing a work hardening program to improve clients' physical function.
本研究旨在调查为背部受伤工人设计的为期12周的工作强化计划的有效性。
在本研究中，招募了32名受试者。评估前后的结果用于衡量该计划的有效性。工作强化计划的强度基于超负荷训练原则。在计划完成三个月后通过电话联系受试者了解其工作状况。
本研究结果表明，工作强化计划前后受试者的身体需求特征水平存在显著差异。完成工作强化计划的受试者中有75%能够恢复工作。
本研究中背部受伤工人的重返工作率与其他研究相当。因此，本研究表明，在设计工作强化计划以改善客户身体功能时应采用超负荷原则。
