Abstract
Introduction & Aim: Only a small number of papers studied the lumbar muscles of normal people and patients with low back pain among domestic and foreign studies, besides, currently the U.S. standards are applied in assessing the lumbar muscles. Therefore, in this study, the lumbar muscles of Koreans are divided by age and sex to provide basic data for the determination of grade and guidance for further study. Method: Among 10,783 patients who visited hospitals in Seoul for low back pain treatment, 3,656 were calculated through random sampling, compared to 1,693 for men and 1,963 for women. Data on the EMR system were retrieved and randomly extracted from patients who received muscle strength measurements from 2013 to December 31, 2018. The lumbar nerve root force test was measured in seven stages with a 12° gap between 0° and 72° using MedX equipment manufactured using isometric principles. After the first result was completed, statistical verification was performed using the corresponding using independent t-test, comparing it with the average value entered into the existing MedX equipment. Result: Measurements clearly showed a decrease in the lumbar nerve muscle as the age group increased for both men and women and this confirmed statistically significant. It also showed an average decrease of about 60 to 80 ft-ibs in all age groups compared to American standards. Conclusion: It is analyzed that the difference occurs because the figures entered into the MedX equipment are those of normal U.S. Although the study has the disadvantage of not representing all Koreans' lumbar muscles, it has the advantage that it can be used as a basis for future postoperative rehabilitation.
