Comparison of Intra-tester Reliability for Measuring Active Lumbar Range of Motion by three Methods in Healthy Subjects: A Preliminary Study

Abstract Background The superior facet arthroplasty is important for intervertebral foramen microscopy. To our knowledge, there is no study about the postoperative biomechanics of adjacent L4/L5 segments after different methods of S1 superior facet arthroplasty. To evaluate the effect of S1 superior facet arthroplasty on lumbar range of motion and disc stress of adjacent segment (L4/L5) under the intervertebral foraminoplasty. Methods Eight finite element models (FEMs) of lumbosacral vertebrae (L4/S) had been established and validated. The S1 superior facet arthroplasty was simulated with different methods. Then, the models were imported into Nastran software after optimization; 500 N preload was imposed on the L4 superior endplate, and 10 N⋅m was given to simulate flexion, extension, lateral flexion and rotation. The range of motion (ROM) and intervertebral disc stress of the L4-L5 spine were recorded. Results The ROM and disc stress of L4/L5 increased with the increasing of the proportions of S1 superior facet arthroplasty. Compared with the normal model, the ROM of L4/L5 significantly increased in most directions of motion when S1 superior facet formed greater than 3/5 from the ventral to the dorsal or 2/5 from the apex to the base. The disc stress of L4/L5 significantly increased in most directions of motion when S1 superior facet formed greater than 3/5 from the ventral to the dorsal or 1/5 from the apex to the base. Conclusion In this study, the ROM and disc stress of L4/L5 were affected by the unilateral S1 superior facet arthroplasty. It is suggested that the forming range from the ventral to the dorsal should be less than 3/5 of the S1 upper facet joint. It is not recommended to form from apex to base. Level of evidence Level IV

Abstract Background Mechanical low back pain (MLBP) is a major cause of illness and disability, especially in people of working age. People with chronic low back pain often experience anger, fear, anxiety, decrease in physical ability, and inadequacy of role fulfillment. Objective This study aimed to compare the efficacy of extension exercise program versus muscle energy technique in treating patients with chronic mechanical low back pain. Subjects and methods Forty patients complaining of chronic mechanical low back pain participated in the study. Patients were randomly allocated into two equal groups: group A which received spinal extension exercise program and group B which received muscle energy technique. Treatment sessions were given three times per week for four successive weeks. Patients were assessed before and after treatment using visual analogue scale (VAS), Oswestry Disability Index (ODI), and digital goniometer to assess pain intensity, functional disability, and range of motion (ROM) of lumbar spine respectively. Results There was significant decrease in the scores of pain and functional disability in both groups post-treatment especially in group B. There was significant increase in lumbar range of motion in both groups post-treatment, especially in group A. Conclusion Extension exercise program had better effect on improving lumbar range of motion, whereas muscle energy technique was better in decreasing pain and functional disability in patients with chronic mechanical low back pain.
