SPECIFIC SPINAL EXERCISE Three Case Studies Using the MedX Lumbar Extension Machine

The purpose of this research project was to ascertain the effects of specific exercise for the lumbar muscles, by way of the MedX Lumbar Extension Machine, and relative to previous years of exercise without such a machine. Three subjects improved lumbar strength significantly, and in one instance, became pain-free within two months although two years of previous chiropractic and physiotherapy proved ineffective. In two other instances, it became obvious that traditional exercise, including heavy deadlifts, squats and bent barbell rowing had no positive effect on maintaining or improving lumbar strength.
