Muscle Activation and Low Back Pain

What’s This Research About?

This study attempted to investigate whether there was an altered muscular
recruitment in trunk extension from a flexed trunk position after a 2-hour
standing bout. They hypothesized that they would see people using more spine
recruitment instead of gluteus maximus in the PD’s. A secondary area of
investigation was whether there would be any gender differences, and or
velocity differences during trunk extension.

Visual analog scale (VAS) is 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.

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

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."
