Poor lumbar movement control in males exercising at the gym: Assessment and training using pressure biofeedback unit

Abstract

Introduction: Mechanical overloading is one of the causes of low back pain (LBP). Dysfunction of movement control and impaired movement patterns can constitute a potential risk factor for LBP development. Aim: The aim of the study was to assess lumbar extension control in young physically active males with the use of the pressure biofeedback unit (PBU) in the context of the most relevant literature. Material and me thods: Randomly 30 young men regularly training at the gym (mean age 19.7 years) were selected to participate in the study. The survey contained basic data (such as: age, profession, height and weight). The dynamic assessment included abdominal muscle endurance test and three tests for movement extension control (the single straight leg test, the double straight leg test in the supine position and the bench press test). Results and discussion: During the single straight leg test, 63% of the participants did not control lumbar extension for the right leg, and 37% for the left leg. In the double straight leg test, 77% of the participants did not control lumbar extension. During the bench press tests, 22% did not control lumbar extension during barbell lowering and 30% during lifting. Repeated excessive extension, which is frequently inadequately controlled by the neuromuscular system, may cause damage to the spinous processes and the soft tissue. Conclusions: Individuals training at the gym may have a tendency towards uncontrolled lumbar extension. PBU can be useful tool in view of the prevalence of LBP.
