Do People With Back Pain Use Their Back Muscles Differently Than Those Without Back Pain?

What’s This Research About?

Some people experience back pain after standing for long periods of time (pain developers (PDs)) while others do not (non-pain developers (NPDs)). Is it possible that they use their posterior muscles differently? This study investigated exactly that by assessing whether or not there was altered muscular recruitment during trunk extension from a flexed position after a 2-hour standing bout. The authors hypothesized that the low back PDs would recruit more spinal muscles than gluteal muscles. They also looked for gender differences, and or differences in velocity during trunk extension.

Low back pain model (LBP model): A previous study by Gallagher et al., has found that 40-60% of people with no history of back pain will develop pain (Pain developers (PD)) after 2 hours of standing. The others are deemed non-pain developers (NPD). They found that the PD’s also exhibited relaxation of their gluteal muscles in the standing experiment.

Visual analog scale (VAS):  A measurement tool that attempts to get a value for a subjective parameter such as pain. In the case of pain, a subject or patient will be given a sheet of paper with a line on it that notes minimum on one side, and max on the other and told to evaluate and mark their pain along that line.

About the Author:

Catherine brings to her role as a personal trainer a wealth of education and years of athletic experience with training in track and cross country running, gymnastics and rowing, boxing and yoga. She received a B.A. in Sports Medicine and Exercise Physiology from the University of San Francisco and an M.A. in Kinesiology at San Francisco State University. She also holds certifications in ACE, FMS I and II, PRI (Myokinematics, Respiration), Neuromuscular therapy, FRCms, and FR. As an athlete she sustained several injuries, which led her on the path to study and understand the body and the mechanisms of healing. "I was fascinated with everything I learned. Throughout college, I worked with USF athletes as an athletic trainer in the prevention and rehabilitation of injuries. Soon I was able to transfer all of this knowledge into helping everyday people with their aches and pains." Her thirst for knowledge is never quenched and she continues to evolve her practice to stay up to date on the latest research and methods to help her clients with present injuries, pain, and best ways to acquire strength to maintain a healthy body. "I believe assessment is still key in starting with clients but stability, global strength and everyday movement are key to people's longevity, and quality of life. If people can slowly and systematically expose their bodies to different loads to gain strength and mobility they will better succeed to get the most out of their bodies."
