Young men with and without lower back pain core muscle strength comparison

Abstract

Introduction. Lower back pain is the biggest cause of the most years lived with disability in the world [1]. As a percentage 5 – 15 % of low back pain can be approved by a specific cause or diagnose while 85 – 95 % of the cases are without a diagnose or the cause is unknown – this is called non – specific low back pain [2]. When evaluating the cause of lower back problems we often look at core musculature, their condition and function. In most cases the pain makes the negative impact on human’s movement function and muscle strength and aggravates daily life. The aim of this study is to compare core muscle strength in young men with and without lower back pain. Research methods and organization. The permission of LUHS Bioethics center was received (2019 – 11 – 21, Nr. BEC – SR(M)103) to perform the investigation. 27 young males (20 – 30 years old) participated in this study. All of them were training in the same health center mostly 3 times per week, they all have not had any lower extremity and body muscle injuries in the past and current years, the ones who were feeling pain had this sensation for a few days until the test. Most participants were attending the health center three times per week and did not participate in any other sports activity. They were divided into two groups: 1. Experiencing non specific lower back pain (on the scale 1 – 4/10 NRS) (mean age = 25.16 ± 2.66 y/o; BMI – 23.59 ± 0.4 kg/m2). 2. Not experiencing lower back pain (mean age = 25 ± 3.16 y/o; BMI – 23.73 0.5 kg/m2). Both groups age and BMI differences were not statistically significant (p = 0.905; Z = -0.15). In the research we investigated quadriceps and hamstring muscles isokinetic strength using Biodex Pro 4 machine, lumbar flexion, extension, lateral flexion isometric core muscle strength using Back – Check by Dr. Wolff machine. Without these methods questionnaire was made to evaluate age and pain se[...].
