ABSTRACT
Arthur Jones, developer of the Nautilus Exercise Machines, founded the MedX Corporation (https://medxonline.net/" xmlns:xlink="https://www.w3.org/1999/xlink">https://medxonline.net/) in 1972 with the sole purpose of designing machines to test and strengthen the muscles of the knee and low back. His theory claims a measureable inverse relationship between pain and strength as well as pain and flexibility. The case study presented in this chapter experiments with a dataset consisting of the records of patients who underwent aggressive physical therapy using the MedX machines for treatment of low back injuries. One of the several goals was to build a model identifying patients who—prior to treatment—are not likely to successfully complete their treatment program. In this way, both patient and therapist will have some initial expectation about treatment success. The case study incorporates a seven-step knowledge discovery process model. This chapter details this process model and summarizes experimental results.
