ImpairMaster for Guides6

ImpairMaster has ancestors dating back to the 1977 edition of the AMA's Guides.

In the late 70's, my father, Dr. Stanley Kaplan, became one of the leading authorities on the use of the AMA's Guides to the Evaluation of Permanent Impairment. He went on to teach the subject up until 2013 and ultimately earned his name in the 6th Edition of the Guides as a contributing reviewer.

As a budding computer programmer, I saw that the process of calculating impairment was mechanical, and thought I could improve the process by creating a program that would accurately generate an impairment rating report, reducing my father's workload not only in the calculation, but also in typing and proofreading. Essentially, he would only need to do the physical examination of the patient and enter his findings; the program would do the rest.

ImpairMaster was first developed for the Radio Shack TRS-80 Model I, one of the first commercially available microcomputers. As times changed, I redeveloped it for the Apple II, followed by a variety of obscure machines leading up to the IBM PC. Over the years, ImpairMaster was written in BASIC, Apple BASIC, Pascal, C, C++, and Java. It then jumped from a character-based user interface into Windows. In 2005, it was redeveloped as a software service and moved to the Internet.
