In this study taken place in Columbia MO, the two machines called the MedX lumbar extension machine and the Roman Chair were tested to help strengthen the lower back. Lumbar strengthening or isolated muscle resistance training has shown to be 80% of users.
The study, “Limited Range of Motion Lumbar Extension Strength Training” is from the Official Journal of the American College of Sports Medicine. Range of motion in lumbar extension
strength training are explored. Patients with lower back pain who have lower range of motion use isometric testing and exercises to try and strengthen their lower back.
This study from College of Medicine and College of Health and Human Performance, University of Florida, Gainesville, Florida investigates how training and detraining effects lumbar extension strength.
This research project which involved patients in the Orthomed program at the University of California San Diego studied the efficacy of a conditioning program using the MedX Lumbar Extension Machine. The study tracked back strength, lift capacity, self-perception, pain rating, and activity level.
This study is from a physical therapy research paper which examines the impact of isometric lumbar extension torque across 12- and 20-week periods. Participants were put into 5 training groups after completing the 12- or 20-week training. The participants were tested in a seated position at 7 different angles at a 72-degree range of motion (ROM).
In this study, the two different restraint systems to isolate the lumbar extensors were explored.
The two different restraint systems are used through the pelvic
stabilization by preventing movements in the lower part of your body while seated. Restraints are located on the knees and on the bottom of the feet. The goal of the study is to see how the restraint systems can influence lumbar extension strength and the shape of isometric lumbar extension strength curve.
In the conducted research, lumbar strength was compared between healthy asymptomatic geriatric women and symptomatic geriatric females. The INJ group assessed the back strength of the two control groups using MedX lumbar extension machines. The findings revealed a notable increase in range of motion (ROM) and back strength following the use of these machines.
Arthur Jones, pioneer of physical fitness equipment, has taken bold steps in exercise machinery to revolutionize his machines for the treatment of low back pain. Jones also campaigned and produced the first University-wide funding effort in University of Florida’s history.
