  • Objectives : The purpose of this study was to evaluate the relationship between cross-sectional areas of the paraspinal and psoas muscles with low back pain. Methods : We assessed the cross-sectional area of the psoas and paraspinal muscles at the superior part of L4 level and vertebral body of L4 of 132 patients who were hospitalized with a chief complaint of low back pain at Jaseng Hospital of Korean Medicine from January 2013 to April 2013. After calculating the mean psoas area, we divided the patients into 2 groups by whether the psoas cross section was larger or smaller than the mean, and compared the admission period, verbal numeric rating scale(NRS) of low back pain(LBP), and improvement of verbal NRS of LBP. We also subcategorized the patients into acute and chronic groups according to the duration period, and compared the cross-sectional area of the psoas and paraspinal muscles. Results : Although analyses of the verbal NRS of LBP, and improvement of verbal NRS of LBP between groups with larger and smaller psoas cross section areas showed no significant difference, the admission period was significantly shorter in the group with larger psoas cross section areas. There was no significant difference in analyses of cross section areas in the acute and chronic groups. Of the possible prognostic variables, improvement of verbal NRS of LBP showed no correlation, while the admission period displayed a significant correlation. The cross-sectional area of the psoas and paraspinal muscles divided by the area of the vertebral body of L4 had a significant negative correlation with age. Conclusions : The cross-sectional area of the psoas and paraspinal muscles were correlated with the admission period in LBP patients, and the cross-sectional area of the surrounding muscles divided by the area of the L4 vertebral body was negatively correlated with age.

  • Purpose: To evaluate, in patients with degenerative disc disease (DDD), the efficacy of using spinal stabilizing exercises for the reversal? of atrophy of the multifidus and psoas major, reductions in pain and disability, and for increases in paraspinal muscle strength. Methods: Nineteen patients diagnosed with DDD participated for 10 weeks in a spinal stabilization exercise program. Pain and disability were measured before and after exercise using, respectively, a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Paraspinal muscular strength in four directions was evaluated using CENTAUR. Both before and after exercise we used computed tomography (CT) too measure cross-sectional areas (CSAs) of both the left and right multifidus and the psoas major at the upper & lower endplate of L4. Results: After 10 weeks of a spinal stabilization exercise program, pain was significantly decreased from $5.7{\pm}0.9$ to $2.5{\pm}0.9$ (p<0.01); the ODI score decreased from $16.7{\pm}4.9$ to $7.3{\pm}3.1$. Paraspinal muscle strength was significantly increased (p<0.01) and the CSAs of the left and right multifidus and psoas major muscles were significantly increased (p<0.01). Conclusion: Spinal stabilization exercise is effective in reversing atrophy in DDD patients, in reducing pain and disability, and in increasing paraspinal muscle strength. It is an effective treatment foro aiding rehabilitation in these cases.

  • Objective : To quantitatively evaluate the asymmetry of the multifidus and psoas muscles in unilateral sciatica caused by lumbar disc herniation using magnetic resonance imaging (MRI). Methods : Seventy-six patients who underwent open microdiscectomy for unilateral L5 radiculopathy caused by disc herniation at the L4-5 level were enrolled, of which 39 patients (51.3%) had a symptom duration of 1 month or less (group A), and 37 (48.7%) had a symptom duration of 3 months or more (group B). The cross-sectional areas (CSAs) of the multifidus and psoas muscles were measured at the mid-portion of the L4-5 disc level on axial MRI, and compared between the diseased and normal sides in each group. Results : The mean symptom duration was $0.6{\pm}0.4$ months and $5.4{\pm}2.7$ months for groups A and B, respectively (p<0.001). There were no differences in the demographics between the 2 groups. There was a significant difference in the CSA of the multifidus muscle between the diseased and normal sides (p<0.01) in group B. In contrast, no significant multifidus muscle asymmetry was found in group A. The CSA of the psoas muscle was not affected by disc herniation in either group. Conclusion : The CSA of the multifidus muscle was reduced by lumbar disc herniation when symptom duration was 3 months or more.

  • A psoas compartment block has been used to provide anesthesia for orthopedic surgical procedures and analgesia for post-operative pain. Currently, this block is advocated for relieving pain in the lower extremity and pelvic area resulting from various origins. We report a case of a 69-year-old male patient who had gait abnormality with posterior pelvic and hip pain, which were both aggravated by hip extension. From the magnetic resonance image, the patient was found to have a laterally herniated intervertebral disc at the L2/3 level, which compressed the right psoas muscle. This was thought to be the origin of the pain, so a psoas compartment block was performed using 0.25% chirocaine with triamcinolone 5mg, and the pain in both the pelvis and hip were relieved.

  • Purpose : This study aimed to examine the effects of sling exercise therapy on the relief of low back pain and the cross-sectional area change of lumbar muscles by CT analysis for chronic low back pain patients. Methods : Forty-one patients with diagnosis of chronic low back pain was divided sling exercise therapy group(SEG) 19 subjects and conservative physical therapy group(CPG) 22 subjects. we randomized and treated them(subjects) for 12 weeks. As using visual analogue scale(VAS), we evaluated recovery accuracy of pain, and for investigating cross-section area change of lumbar muscles for before and after treatment we used computed tomography(CT). Results : This study were summarized as follows : 1) As treatment period, in each compared testing on VAS of SEG and CPG, the both group was significantly different(p<.05). 2) Compared testing on VAS of between-subject groups(SEG and CPG) were not significantly different(p>.05). 3) At SEG of before and after treatment, in compared testing on cross-section area size of lumbar muscles, All muscles of psoas major, quadratus lumborum, erector spinae and multifidus were significantly different(p<.05). At CPG, psoas major was significantly different(p<.05). But other muscles were not significantly different(p>.05). Conclusion : From this result, both sling exercise therapy and the conservative physical therapy are effect on decrease of pain for chronic low back pain patients. but Increasing of the cross-section area being proportioned with muscular strengthening of low back muscle is noticeable difference in SEG. Therefore, sling exercise therapy have affect both decreasing of pain for chronic low back pain patients and lumbar muscles strengthening.

  • Objectives The purpose of this study was to investigate the correlation between walking ability of lumbar spinal stenosis patients and the cross-sectional area (CSA) of lumbar paraspinal muscles. Methods This study was carried out on 62 lumbar spinal stenosis patients who had limited walking abilities because of neurogenic claudication (NC). All patients received more than 2 weeks of complex treatment at Mokhuri Neck&Back Hospital. CSA of lumbar paraspinal muscles was measured from axial T2-weighted MRI and divided by CSA of adjacent vertebral body to avoid influence of body statues (RCSA-Relative CSA). Pain Free Walking Distance and Numerical Rating Scale (NRS) was measured before and after treatment. Results The Pain Free Walking Distance had significantly increased in patients who had bigger RCSA of psoas muscle (r=0.313, p<0.05). Conclusions The psoas muscle can be a predictive factor for restoring walking ability of lumbar spinal stenosis patients who have limitations walking.

  • Objectives To investigate correlation between slip percentage (SP) of spondylolisthesis and cross-sectional area (CSA) of lumbar paraspinal muscles; psoas major (PM), multifidus (MU) and erector spinae (ES). Methods A retrospective study was carried out in 120 spondylolisthesis patients who had visited the Spine center of Kyung Hee University Hospital at Gangdong and had taken lumbar MRI. CSA of lumbar paraspinal muscles was measured from axial T2-weighted MRI and divided by CSA of vertebral body to avoid weight's influence. SP was also measured from sagittal MRI. Results SP increase has significant correlation with decreased CSA-MU (r=0.37, p<0.01) and increased CSA-ES (r=0.19, p<0.05). There was no significant correlation between SP and CSA-PM. Conclusions MU atrophy and ES hypertrophy have significant correlation with SP of spondylolisthesis. CSA of lumbar paraspinal muscles can be a risk factor of progression of spondylolisthesis and compensation for the instability.
