The purpose of this study was to investigate the variations in gait pararreters in tenns of the type of ann sling used in hemiplegic patients. Ten patients with hemiplegia and ten healthy adults participated in this study and walked at self-selected speeds on a GAITRite-instn.urented carpet. The activities of the opposite shoulder girdle muscle including the latissimus dorsi, anterior deltoid, and posterior deltoid were sinmltaneously ra:orded using surface ElVIG during gait. They were randomly assigned a condition: without an ann sling, a single strap ann sling, a Harris hemi ann sling, a Rolyan hurreral cuff ann sling, and a Bobath roll ann sling. The following gait variables were analyzed: the temporo-spatial pararreters of velocity, step length, stride length, swing phase, stance phase, single SupjXlrt, step titre and toe in/toe out. The statistical analysis was one-way ANOVA with rer;eated rreasures to compare the variation of each variable. In comparison of pararreters in each trial in the hemiplegia group, the non-affa:ted side stride length, single support, and toe inltoe out resulted in statistically significantly changes (p<'C5). But without an ann sling group did not show any gait pararreter differences with ann slings. Ths study found that several ann slings varied gait patterns in patients with hemiplegia and in healthy adults. In the ElVIG analysis, the Rolyan hurreral cuff ann sling and the Bobath roll ann sling were higher muscle activity for the latissimus dorsi muscle than did the single strap ann sling. Further study should examine the problems that appeared in patients who worn ann slings by focusing on a larger number of subja: ts and by studying the variety of responses in rmre detail using an assessrrent tool that rreasures variation

Background Clamshell exercise is commonly used as a rehabilitation strengthening exercise for the gluteus medius muscle, which plays a large role in human walking, weight-bearing activities, and pelvic stabilization. Compensatory movements such as excessive horizontal rotation of the pelvis may occur during clamshell exercises. Various studies on pelvic control have been conducted, but studies on how to control pelvic rotation using tools are lacking. Objectives The purpose of this study was to investigate the effects on gluteus medius activity and pel-vic rotation when adjusting pelvic rotation using a smartphone-based measurement tool during clam-shell exercise. Methods This study recruited 27 healthy adult females. During clamshell exercise, gluteus medius muscle activity and pelvic rotation were investigated with and without the use of a smartphone-based measurement tool. Gluteus medius activity was measured with 4D-MT 2EM, and pelvic rotation was analyzed using the Kinovea® program. Statistical analysis was performed using t-test. Results The activity of the gluteus medius muscle significantly increased and the amount of pelvic rota-tion significantly decreased in the clamshell exercise with the use of the smartphone-based measure-ment tool compared to the clamshell exercise using the pelvic rotation control method without the use of a smartphone-based measurement tool (p < 0.001). Conclusions The use of a smartphone-based measurement tool during clamshell exercise can help the efficient activation of the gluteus medius muscle by minimizing compensatory actions such as un-wanted rotation of the pelvis.

The purpose of this study was to evaluate the changes in the electromyographic (EMG) activity of the trunk and the lower limb muscles during quiet standing on an unstable surface while wearing low-heeled shoes (3 ㎝), high-heeled shoes (7 ㎝) and without footwear (0 ㎝) in 20 young healthy women. The subjects stood on an unstable surface for 30 seconds. We examined the differences in the EMG data of the erector spinae, rectus abdominis, biceps femoris, rectus femoris, tibialis anterior, and the gastrocnemius medialis muscle. A one-way repeated analysis of variance was used to compare the effects of shoe heel height on the EMG activity with the level of significance set at α=.05. The EMG activity of the erector spinae and the rectus femoris were significantly increased (p<.05) in the subjects who wore elevated heel height, while the tibialis anterior and the gastrocnemius medialis were significantly decreased (p<.05). However, the rectus abdominis and the biceps femoris exhibited no significant difference among the three conditions. The above results indicate that wearing high-heeled shoes may change the postural strategy. The findings of this study suggest that excessive heel height could contribute to an increased fall risk during quiet standing.

박천준(Cheon-jun Park),안덕현(Duk-hyun An) 한국전문물리치료학회 2020 한국전문물리치료학회지 Vol.27 No.1

Background: A backpack is available equipment for moving some objects. Most studies have found that the appropriate weight limit of backpack for students is between 10% to 15% of their body weight (BW). However, Some students should carry a backpack heavier than 15% of BW. Therefore, It is associated with abnormal shoulder and neck posture on students. Objects: This study tested the effects that various amounts of weight carried by university students in their backpacks had on their cervical posture and electromyography of neck muscle. Methods: The subjects consisted of 12 students (6 male, 6 female) in university. There were three loading conditions tested: no backpack, a backpack that weighed 10% and 15% of the student’s BW. The dependent variables were the craniovertebral angle (tragus to C7) and the neck muscle activities (sternocleidomastoid, upper trapezius). All 12 subjects were asked to walk while wearing a backpack for 5 minutes and were then instructed to rest for 2 minutes. Results: When assessing the craniovertebral angle, the results of this study were significantly decreased in the order of 0%, 10%, and 15%. And then, there were significantly increased electromyography of neck muscles that comparison of the weight of 10% and 15% on 0%. It was found that as the weight of the backpack increased, the craniovertebral angle decreased (p < 0.05) and the muscle activities increased (upper trapezius p = 0.012, sternocleidomastoid p = 0.013). Conclusion: Our study recommended that some students shouldn’t carry on over the 15% backpack of own weight, and also they should distribute backpack load to equal on body for optimal posture.

본 연구의 목적은 4가지의 다른 형태의 팔걸이를 이용하여 상지의 움직임을 제한하였을 때, 보행양상에 미치는 영향을 알아보고, 기능적인 보행을 획득하기 위한 기초자료를 제공하는 것이다. 건강한 성인 남녀 20명을 대상으로 미착용 상태와 단일 끈형, 해리스 편측형, 뇌졸중용, 로리안 상완 커프형 팔걸이를 착용한 상태에서 무작위 순으로 GAITRite system을 통해 보행평가를 시행하였다. 팔걸이를 착용한 동측 하지의 보장에서 유의한 결과를 나타냈다(p=.002). 팔걸이를 착용하지 않았을 때보다 해리스 편측형 착용시에 팔걸이를 착용한 동측 하지의 보장이 감소되었다(p=.001). 신전형 팔걸이인 로리안 상완 커프형 착용시에 해리스 편측형 착용 시에 비해 동측 하지의 보장이 증가되었다(p=.01). 보행속도, 유각기, 단하지 지지기, 분속수에서는 통계적으로 유의한 변화가 없었다. 앞으로의 연구에서는 팔걸이를 착용하는 환자들에게 나타나는 보행변화에 대한 연구와 기능적인 보행패턴을 획득하기 위한 운동학적 측면의 연구가 이루어져야 할 것이다. The purpose of this study was to investigate the variations in gait parameters according to arm slings used in healthy adults. Twenty healthy adults (9 males, 11 females) participated in this study and walked at self-selected speeds on a GAITRite-instrumented carpet. They were randomly assigned conditions: without an arm sling, a care sling, a Harris hemi arm sling, a CVA sling, and a Rolyan humeral cuff sling. The following gait parameters were analyzed: the temporo-spatial parameters of gait velocity, swing phase, single support, cadence. In the comparison of parameters in each trial, step length was statistically significantly changed (p=.002). The right step length was significantly decreased in the Harris hemi arm sling and increased in the Rolyan humeral cuff sling when compared with no sling. This study found that several different types arm slings varied gait pattern in healthy adults.

Background : Trunk stabilization exercises activate the stabilizing muscles of the trunk and essential for the correct function of the lumbo-pelvis. The bridge exercise increases the activity of the trunk stabilizing muscle, and is also used for the treatment of these muscles. Various studies related to sling exercise have been conducted, although none of them examined its effects on the muscle activity of trunk stabilizing muscles when the bridge exercise was performed by applying the sling neurac method. Objectives : The purpose of this study was to investigate which support surface the trunk and hamstring muscles high activity during bridge exercise using sling neurac method. Methods Seven teen healthy subjects, and the surface electromyography was attached to transverse abdominis, multifidi, and the dominant side hamstring muscles. Then, the maximum voluntary isometric contraction was measured. The bridge exercise was performed on either the floor, on a foam roller, and sling surface by randomly. A one-way repeated measures ANOVA was performed to determine the difference in muscle activity between the surfaces. Results : There was a significant difference in the activity of all muscles according to the difference in the supporting surface (p < 0.05). In the transverse abdominis, the sling surface showed significantly higher than the other support surfaces (p < 0.001). Conclusions : In this study, the more unstable the support surface, the highly muscle activity in all muscles. Especially, in the sling neurac method, a significant increase in the transverse abdominis muscle activity was observed compared to the other surfaces. These results suggest that exercise on a support surface applying the sling neurac method can simultaneously induce the contraction of the trunk stabilization muscles and hamstrings. Therefore, the bridge exercise using the sling neurac method proposed in this study is an effective way to strengthen the hamstring muscles while maintaining the stability of the trunk.
