This paper discusses research findings relating of the use of the machine that provides isolated, specific exercise and testing for the muscles that extend the lumbar spine (lumbar extension machine, MedX, Ocala , FL ). The function of the machine is explained, and its reliability and validity examined. The effects of various lumbar extension training protocols on lumbar strength and low back pain are then explored, and practical implications and future research directions discussed. We conclude that that the lumbar extension machine provides reliable and accurate measures of lumbar extension strength and can produce very large increases in low back strength in a relatively short time period. Perhaps more importantly given the huge costs of low back problems, it is a very effective tool for preventing or eliminating low back pain in most chronic patients.
