  • PURPOSE: We investigated the relationship between the segment of erector spinae during a core stability exercise according to visual control. METHODS: The subjects of this study were 20 healthy students. An 8-channel electromyograph was used to measure muscle activities of the erector spinae by segment(cervical, thoracic and lumbar) during a core stability exercise according to visual control. The collected data were analyzed using the independent t-test and Pearson-test. RESULTS: The activity of the erector spinae for all segment was higher without the vision than with. The activity of right cervical erector spinae was significantly increased by increasing the activity of the left thoracic erector spinae during a core stability exercise with vision (r= .555). The activity of left thoracic erector spinae was significantly increased by increasing the activity of the left lumbar erector spinae during a core stability exercise without vision (r= .472). CONCLUSION: There was a positive correlation between the cervical and thoracic segment of erector spinae during a core stability exercise with vision. There was a positive correlation between the thoracic and lumbar segment of erector spinae during a core stability exercise without vision.

  • This present study investigated the effects of the abdominal drawing-in maneuver (ADIM) and chin tuck (CT) on middle thoracic erector spinae, lower thoracic erector spinae, and lumbar erector spinae muscle activity during three prone thoracic extension (PTE) exercises. Twelve healthy subjects performed preferred PTE, ADIM PTE, and ADIM-CT PTE. Surface electromyography was used to collect data on the muscle activity of dominant middle and lower thoracic erector spinae muscles and the lumbar erector spinae. Middle and lower thoracic erector spinae muscle activity significantly increased when ADIM and CT was performed (p<.05). However, lumbar erector spinae muscle activity significantly decreased in ADIM PTE compared to preferred PTE (p=.017) and significantly increased in ADIM-CT PTE compared to ADIM PTE (p=.004). In conclusion, ADIM-CT PTE effectively increased middle and lower thoracic erector spinae muscle activity, and ADIM PTE decreased lumbar erector spinae muscle activity. Hence, ADIM PTE could be a recommended exercise maneuver to strengthen thoracic erector spinae without over activation of lumbar erector spinae.

  • Background: Although the erector spinae plane block has been used in various truncal surgical procedures, its clinical benefits in patients undergoing spinal surgery remain controversial. The aim of this meta-analysis was to evaluate the clinical benefits of erector spinae plane block in patients undergoing spinal surgery. Methods: We searched the Cochrane Library, PubMed, EMBASE, and China National Knowledge Infrastructure for randomized controlled trials comparing the erector spinae plane block with a nonblocked control for spinal surgery. Results: Twelve studies encompassing 696 subjects were included in our systematic review and meta-analysis. We found that the erector spinae plane block decreased postoperative pain scores and opioid consumption in the postoperative and intraoperative periods. Moreover, it prolonged the time to the first rescue analgesic, reduced the number of patients who required rescue analgesia, and lowered the incidence of postoperative nausea and vomiting. However, it did not exhibit efficacy in decreasing the incidence of urinary retention and itching or shortening the length of hospital stays, or the time to first ambulation. Conclusions: Erector spinae plane block improves analgesic efficacy among patients undergoing spinal surgery compared with nonblocked controls; however, there is insufficient evidence regarding the benefits of erector spinae plane block for rapid recovery.

  • The purposes of this study were to examine the effect of two different pelvic alignments and the Valsalva maneuver on electromyographic (EMG) activity of the erector spinae during squat lifting and lowering, and to find an efficient method for squat lifting and lowering. Twenty hea1thy men in their twenties lifted and lowered loads using four different methods: 1) anterior pelvic tilt position with the Valsalva maneuver, 2) anterior pelvic tilt position without the Valsalva maneuver, 3) posterior pelvic tilt with the Valsalva maneuver, 4) posterior pelvic tilt without the Valsalva maneuver. The EMG activity of erector spinae was recorded during both lifting and lowering with each method. The EMG activity of each individual was normalized to EMG activity produced by muscle during maximal voluntary contraction. Two-way analysis of variance for repeated measures ($2{\times}2$) was used to analyze the effect of the two factors: 1) pelvic tilt position (anterior pelvic tilt, posterior pelvic tilt), 2) the Valsalva maneuver (with and without). Analysis was performed separately for the lifting and lowering. The results were as follows: 1) EMG activity of erector spinae was greater when the pelvis was tilted anteriorly than when the pelvis was tilted posteriorly during squat lifting and squat lowering. 2) There was no difference between EMG activity of erector spinae with the Valsalva maneuver and EMG activity of erector spinae without the Valsalva maneuver during squat lifting and squat lowering. These results suggest that the greater EMG activity of erector spinae with an anterior pelvic tilt position during squat lifting and squat lowering may ensure optimal muscular support for the spine while handling loads, but the Valsalva maneuver may have less effect on erector spinae.

  • Purpose : The purpose of this study is to examine inter-and intra-rater reliabilities of myotonometric measurements of tone, elasticity and stiffness for the erector spinae muscles of the young and the elderly populations. Methods : A total of 102 (69 young adults from K university and 33 older adults from the D community center in Daejeon) were enrolled in this study. The two different raters measured each side of the erector spinae muscles at prone position. After each rater performed first measurement for a subject, 30 minutes of rest was given. The same rater then repeated the second myometric measurement on the subject. The collected data on the tone, elasticity, and stiffness of the erector spinae were analyzed using intraclass correlation coefficient (ICC) to determine inter- and intra- rater reliabilities. Results : The inter-and intra-rater reliabilities of the myotonometric measurement of the erector spinae for the total subjects were excellent (ICC > 0.9, p < 0.001). Within each of the elderly group and the young group, inter- and intra-rater reliabilities were also excellent (ICC > 0.8~0.9 / p < 0.001, ICC > 0.75~0.9 / p < 0.001, each). Conclusion : The measurement of muscle tone, elasticity, and stiffness for the erector spinae muscles using the myotonometer had excellent reliability. It was confirmed that a highly reliable myometric measurement on the erector spinae can be obtained regardless of whether it is from young or elderly people. This suggests that the myotonometer can be a useful tool to measure muscular properties of the erector spinae of the young and old as an evaluative instrument.

  • Purpose : This study aimed to investigate age-related mechanical changes in the erector spinae muscles, specifically in terms of tone, elasticity, and stiffness, in the elderly population compared to the younger population Methods : The mechanical properties, including tone, elasticity, and stiffness, of the erector spinae muscles were measured using myotonometry in 47 male adult subjects, divided into the younger group (23 subjects aged 19 to 28 years) and the elderly group (22 subjects aged 69 to 83 years). The measurements were performed in both the prone and sitting positions. The tone, elasticity, and stiffness of the erector spinae muscles were statistically compared between the two groups using a t-test. Results : The study showed increased stiffness and decreased elasticity in the erector spinae muscles in the elderly group compared to the younger group (p<0.01~0.001). The results were similar in both the prone and sitting positions. Conclusion : There are age-related degenerative changes that affect the mechanical properties of the erector spinae muscles. In addition, myotonometry can be suggested to be a useful examination tool in evaluating these changes provided that further studies are conducted and standard methods of application have been established in the future.

  • Purpose: The purpose of this study was to compare the effects of new exercises (combined cervical and thoracic extension exercises) with those of conventional cervical extensor strengthening exercises (sitting cervical extension exercises) and thoracic extensor strengthening exercises (prone thoracic extension exercises). Method: Fifteen healthy subjects performed sitting cervical extension exercises, prone thoracic extension exercises, and combined cervical and thoracic extension exercises. During each exercise, electromyography was used to measure muscle activity in the erector spinae with C4 and T4 levels. The measured data were analyzed using one-way repeated analysis of variance. Results: With different exercises, there were significant differences in activity in the erector spinae muscle (p < 0.05). The activity in the erector spinae muscle increased significantly during the combined cervical and thoracic extension exercises compared to the sitting cervical extension (p < 0.05) and prone thoracic extension exercises (p < 0.05). The sitting cervical extension exercises significantly increased activity in the cervical erector spinae muscle compared to the prone thoracic extension exercises (p < 0.05). Activity in the thoracic erector spinae muscles was significantly increased during the prone thoracic extension exercises compared to during the sitting cervical extension exercises (p < 0.05). Conclusion: These findings suggest that the newer exercises effectively increase activity in the cervical and thoracic extensor muscles.

  • Background: The flexion-relaxation phenomenon (FRP) refers to a sudden onset of activity in the erector spinae muscles that recedes or fades during full forward flexion of the trunk. Lumbar spine and hip flexion are associated with many daily physical activities that also impact trunk flexion. Shorter hamstring muscles result in a reduction of pelvic mobility that eventually culminates in low back pain (LBP). Many studies have explored the FRP in relation to LBP. However, few studies have investigated the influence of hamstring muscle length on the FRP in relation to the erector spinae muscles during trunk flexion. Objects: This study aimed to investigate the influence of hamstring muscle length on the FRP in relation to the erector spinae muscles during trunk flexion. Methods: Thirty subjects were divided into three groups according to hamstring length measured through an active knee extension test. The 30 participants consisted of 10 subjects who had a popliteal angle of 20° or less (Group 1), 10 subjects who had a popliteal angle of 21°-39° (Group 2), and 10 subjects who had a popliteal angle of 40° or more (Group 3). A one-way analysis of variance was used to compare the difference in muscle activity of the erector spinae muscles during trunk flexion. Results: The subjects with a shorter hamstring length had significantly higher muscle activity in their erector spinae muscles during trunk flexion and full trunk flexion (p < 0.05). The subjects with a shorter hamstring length also had a significantly higher flexion-relaxation ratio (p < 0.05). Conclusion: The results of this study demonstrate that differences in hamstring muscle length can influence the FRP in relation to the erector spinae muscles. This finding suggests that the shortening of the hamstring might be associated with LBP.

  • The purpose of this study was to compare the onset times of muscle activities and the order of muscle firing in hamstring gluteus maximus, and lumbar erector spinae muscle during active hip extension between subjects with low back pain (LBP) and healthy subjects. Thirty subjects, 15 with LBP and 15 healthy subjects, participated in this study. Electromyographic activity was recorded during active hip extension in prone and standing position. Relative onset times of these muscle activities were determined. Similar muscle firing order in hamstring, gluteus maximus, and lumbar erector spinae muscle showed in both groups and positions. However, the onset time of gluteus maximus was significantly later in prone and standing active hip extension in subjects with LBP than in healthy subjects. The onset time of lumber erector spinae muscle activity was significantly delayed in subjects with LBP in standing active hip extension, The delayed onset times of gluteus maximus and lumbar erector spinae muscles' activities were probably related to LBP. Further studies are needed to identify whether the delayed onset times of gluteus maximus and lumbar erector spinae muscle activities are the contributing factors to LBP.
