     View Summary

    BACKGROUND: External focus isometric exercises using a paper balloon can change trunk muscle activation in the chest squeeze; however, it is unknown whether this method affects muscle activities in conventional exercises. OBJECTIVE: To check variations of trunk muscle activity during front plank (static task) and shoulder press (dynamic task) both with and without instruction to avoid crushing an object. METHODS: Twenty-six healthy adult males aged 19–49 were recruited. Ten trunk muscle activities were measured using surface electromyography during a front plank and dynamic shoulder press exercises, both with and without external-focus instruction. RESULTS: Adding the external-focus using the paper balloon to the front plank significantly activated 8 out of the 10 muscles. In the downward shoulder press, 5 out of 10 muscles with 50% 1 RM, 2 out of 10 muscles with 100% 1 RM were significantly activated. CONCLUSIONS: Adding external-focus instruction using paper-balloon increases trunk muscles in front plank and shoulder press while possibly improving trunk stability. Novel exercises using paper balloon may efficiently activate specific muscles without external loading thus possibly reducing the stress on the involved joints during exercise.

    <title>Abstract</title><sec>
    <title>Background</title>
    Medial tibial stress syndrome is a common sports related injury. Altered foot kinematics can be a risk factor for the injury. Since foot segments can move independently, intersegment coordination is important for proper foot function. This study aimed to compare the foot intersegmental coordination pattern and single segment kinematics between female lacrosse players with and without a history of medial tibial stress syndrome during drop jump.


    </sec><sec>
    <title>Methods</title>
    Twelve players with a medial tibial stress syndrome history and 12 players with no history were enrolled. Foot kinematics, including angle at landing and peak angle and excursion at the rearfoot, midfoot, and forefoot during single-leg drop jumps were analysed. Each segment motion data from landing to leaping was time-scaled to 100% to analyse the intersegmental coordination with a modified vector coding technique. Instant intersegmental coordination of every 1% was classified into four patterns (in-phase, two segments rotate in the same direction with similar amplitudes; anti-phase, two segments rotate in opposite directions; proximal phase, proximal segment dominantly rotates in the same direction compared to the distal segment; and distal phase, distal segment dominantly rotates in the same direction compared to the proximal segment). The percentage of intersegmental coordination pattern and kinematics in each segment were compared between the groups using the Student’s t test.


    </sec><sec>
    <title>Results</title>
    Groups with a history of medial stress syndrome showed a significantly higher percentage of proximal phase between the rearfoot and midfoot in the sagittal (Mean ± SD; history, 52.2 ± 17.9%, no history, 29.3 ± 16.7%; <italic>p</italic> = 0.004) and coronal planes (history, 40.3 ± 22.0%, no history, 15.9 ± 9.1%; <italic>p</italic> = 0.004). Dorsiflexion excursion (history, 34.5 ± 4.5°, no history, 29.6 ± 2.1°; <italic>p</italic> = 0.003) were significantly larger in a history of medial tibial stress syndrome group compared to no history group.


    </sec><sec>
    <title>Conclusions</title>
    Rearfoot dominant motion pattern relative to the midfoot may be related to medial tibial stress syndrome. Intersegmental coordination analysis may be useful for detecting abnormal foot coordination patterns. Also, stabilization for the rearfoot may be required rather than the midfoot for intervention.

     View Summary

    <italic><bold>Context</bold>:</italic> The quadratus lumborum (QL) is expected to contribute to segmental motor control of the lumbar spine to prevent low back pain. It has different layers (anterior [QL-a] and posterior [QL-p] layers), whose functional differences are becoming apparent. However, the difference between the QL-a and QL-p activities during bridge exercises utilized in rehabilitation is unclear. <italic><bold>Objective</bold>:</italic> To compare QL-a and QL-p activities during bridge exercises. <italic><bold>Design</bold>:</italic> Repeated-measurement design was used to assess electromyographic activity of trunk muscles recorded during 14 types of bridge exercises. <italic><bold>Setting</bold>:</italic> University laboratory. <italic><bold>Participants</bold>:</italic> A total of 13 healthy men with no history of lumbar spine disorders participated. <italic><bold>Intervention</bold>:</italic> The participants performed 14 types of bridge exercises (3, 3, and 8 types of side bridge, back bridge, and front bridge [FB], respectively). <italic><bold>Main Outcome Measures</bold>:</italic> Fine-wire electromyography was used for QL-a and QL-p activity measurements during bridge exercises. <italic><bold>Results</bold>:</italic> Both QL-a and QL-p showed the highest activity during the side bridge with hip abduction  (47.3% [29.5%] and 43.0% [32.9%] maximal voluntary isometric contraction, respectively). The activity of the QL-a was significantly higher than that of the QL-p during back bridge with ipsilateral leg lift and FB elbow–toe with ipsilateral arm and contralateral leg lift (<italic>P</italic> &lt; .05). With regard to the QL-p, the activity of the FB hand–knee with contralateral arm and ipsilateral leg lift, the FB elbow–knee with contralateral arm and ipsilateral leg lift, and the FB elbow–toe with contralateral arm and ipsilateral leg lift were significantly higher than that of the FB elbow–knee and FB elbow–toe (<italic>P</italic> &lt; .05). <italic><bold>Conclusion</bold>:</italic> This study indicates different regional activities; the QL-a activated during the back bridge with ipsilateral leg lift and FB with ipsilateral arm lift, and the QL-p activated during the FB with ipsilateral leg lift. These results have implications for the rehabilitation of low back pain or lumbar scoliosis patients based on QL recruitment.

     View Summary

    The purpose of this study was to examine the influence of a history of low back pain (LBP) on pelvic and lumbar kinematics during baseball hitting. Twenty collegiate male baseball players (age, 21±1 years; height, 172.8±4.7 cm; weight, 72.7±6.2 kg; baseball experience, 13±1 years) performed 5 bat swings. Participants were categorized into the LBP group (n=10) or control group (n=10) based on having experienced lumbar spine pain due to bat swing that lasted more than 24 h within the last 12 months. Three-dimensional kinematic data of the pelvis and lumbar spine during bat swing were measured. Two-way ANOVAs were used to compare pelvic and lumbar kinematics throughout the bat swing between groups, and independent t-tests were used to compare the other outcomes between groups. There was a significant main effect between groups in lumbar flexion angle throughout the bat swing (p=0.047). The mean lumbar flexion angle of the LBP group throughout the bat swing was less than that of the control group. Additionally, the peak angular velocity of lumbar flexion of the LBP group was significantly faster than that of control group (p=0.047). These results can be helpful for longitudinal studies that identify the risk factors of LBP due to bat swing.

    Authorship:Lead author

     View Summary

    [Purpose] To compare the lumbar lordosis angle and electromyographic activities of the trunk and lower-limb muscles in the hip neutral position and external rotation during back squats. [Subjects and Methods] Ten healthy males without severe low back pain or lower-limb injury participated in this study. The lumbar lordosis angle and electromyographic activities were measured using three-dimensional motion-capture systems and surface electrodes during four back squats: parallel back squats in the hip neutral position and external rotation and full back squats in the hip neutral position and external rotation. A paired t-test was used to compare parallel and full back squats measurements in the hip neutral position and external rotation, respectively. [Results] During parallel back squats, the average lumbar lordosis angle was significantly larger in hip external rotation than in the hip neutral position. During full back squats, lumbar erector spinae and multifidus activities were significantly lower in hip external rotation than in the hip neutral position, whereas gluteus maximus activity was significantly higher in hip external rotation than in the hip neutral position. [Conclusion] The back squat in hip external rotation induced improvement of lumbar kyphosis, an increasing of the gluteus maximus activity and a decrease of both lumbar erector spinae and multifidus activities.

     View Summary

    Low back pain (LBP) often occurs in baseball players;however, the characteristics of the location of their LBP with respect to their throwing and hitting sides have not been clarified. In order to clarify the left-right asymmetry of LBP that occurs in baseball players, we surveyed 247 university baseball players using an LBP questionnaire. The main investigational items were:throwing and hitting side, position at the time of LBP experience, and LBP location. Based upon the indication of their throwing and hitting side, subjects were classified into unilateral rotational (UR) or bilateral rotational (BR) types. Subjects were also classified into categories of LBP location as described by ipsilateral or contralateral to dominant side of throwing or hitting. Chi-square test or Fisher exact test were used to compare LBP location side by rotational type (UR/BR) in all subjects and by position (pitcher/fielder). We found that among fielders, LBP occurring contralateral to the hitting side in UR was significantly more frequent than that in BR. We conclude that LBP occurred in baseball fielders with a left-right asymmetry, which suggests that high frequency unilateral rotation causes the lumbar region contralateral to the dominant hitting side to be subject to a high load.

    Journal of physical therapy science   30 ( 1 ) 154 - 158  2018.01  [Refereed]  [Domestic journal]

     View Summary

    [Purpose] To measure electromyographic activity of the piriformis using fine-wire electrodes during 7 hip movements. [Subjects and Methods] Eleven healthy men, without severe low back pain or lower limb injury, participated in this study. Fine-wire electrodes were inserted into the piriformis and surface electrodes were attached to the muscles in the hip region and the trunk muscles on the dominant arm side. Electromyographic signal amplitude was measured during 7 hip movements: side-lying external rotation in hip neutral position, side-lying abduction in hip neutral position, side-lying abduction in hip external rotation, side-lying abduction in hip internal rotation, prone extension in hip neutral position, prone extension in hip external rotation, and prone extension in hip internal rotation. Repeated-measures one-way analysis of variance was used to examine electromyographic activity in each of the 7 hip movements. [Results] Piriformis electromyographic activity was highest during prone hip extension in external rotation. Both the superior and inferior portions of the gluteus maximus were also highly activated during prone hip extension in external rotation. [Conclusion] Prone hip extension in external rotation induced high electromyographic activity in the piriformis and superior and inferior gluteus maximus muscles.

     View Summary

    &nbsp; &nbsp; The aim of present study is to clarify the acute effect of baseball movements on the lumbar intervertebral disc. Lumbar intervertebral disc degeneration occurs frequently in baseball players, changes to intervertebral disc herniation, and takes a long time for the players to return to competition. In recent years, a method has been used in which magnetic resonance imaging is taken before and after exercise to non-invasively evaluate the load on the lumbar intervertebral disc due to exercise. Using this method, we are verifying which the baseball movements have the greatest effect on lumbar intervertebral disc degeneration.&nbsp; &nbsp; Currently, the experiment is ongoing, and the experiment of nine participants has been completed. Analysis of the data currently collected suggests that catching a ground ball affects the content of water molecules and movement of water molecules in the lumbar intervertebral disc, which are indicators of load on the intervertebral disc, compared with other movements. The results of present study, including data to be collected in the future and data that is currently unanalyzed, will be published as academic conferences and papers at domestic and overseas.
