PURPOSE: This study aimed to provide basic clinical data by analyzing the impact of motion observation training and stretching exercises for improving postures on the neck alignment and balance of stroke patients to enable them to accurately recognize the correct exercise method. METHODS: After sampling 20 stroke patients who met the selection criteria, this study randomly assigned 10 people who were administered the stretching exercise with observation training to the experimental group and 10 who received only the stretching exercise intervention to the control group by drawing lots. Next, neck alignment and balance were pre-tested. All interventions were conducted for 30 minutes, times a week for 4 weeks, and when all the interventions were completed after 4 weeks, neck alignment and balance were re-measured in the same way as the pre-test. RESULTS: The comparison of changes in neck alignment and balance within the experimental and control groups showed statistically significant differences in the craniovertebral angle, cranial rotation angle, and balance (p < .05) (p < .01). Between the groups, statistically significant differences were found in the craniovertebral angle, cranial rotation angle, and balance (p < .05) (p < .01). CONCLUSION: A statistically significant difference in neck alignment and balance was observed in the group that underwent stretching exercises combined with observational training and a statistically significant difference was found between the groups. Therefore, it is believed that observation training should be used in clinical practice to improve forward head posture and restore balance in stroke patients.

강정일,김희경,정대근 국제물리치료연구학회 2019 Journal of International Academy of Physical Ther Vol.10 No.3

Background: Although there are interventions available for the improvement of arm functions of patients with stroke, measuring changes in global synkinesis (GS) according to changes in the muscle activity of paretic and nonparetic side muscles is an important factor and studies to investigate such potential factors are evaluated necessary. Objective: To examine the correlation between the affected arm muscle activity and GS changes in patients with stroke. Design: Randomized controlled trial Methods: In order to measure muscle activities of 30 stroke patients, anterior deltoid, posterior deltoid, biceps brachii and triceps brachii of the affected arms were measured using surface electromyography (EMG) and for analyzing GS, biceps brachii and triceps brachi of the affected arms were measured using the same instrument. Results: When the correlations between the muscle activity and GS of the affected arm were analyzed, the results showed significant correlations between the posterior deltoid and the triceps brachii(p < .01) and between the triceps brachii and GS(p < .05). Conclusion: : The results of this study suggest that the efficient movements of the affected arms of stroke patients, it is possible to increase extensor activity by improving smooth antagonism of the arm.

PURPOSE: This study aimed to analyze the effects of task exercise on an unstable surface on the involuntary arm and leg movement and balance in stroke patients. METHODS: 20 stroke patients were clinically sampled and randomly assigned to two groups of 10 patients each. Experimental group Ⅰ received task exercise intervention on an unstable surface and experimental group Ⅱ received task exercise intervention. The interventions were carried out 3 times a week for 4 weeks (30 minutes per session). The global synkinesis (GS) and Berg Balance Scale (BBS) of the patients were evaluated as pre-tests prior to intervention, and then the post-tests were re-measured in the same manner as the pre-tests after a 4-week intervention period. RESULTS: In the experimental group I, there were statistically significant differences in the changes in the arm and leg GS (p < .01) and in the BBS (p < .05). On the other hand, in the experimental group Ⅱ, there were statistically significant differences in the changes only in the arm GS (p < .01) and in the BBS (p < .05). Also, in the comparison of the changes between the two groups, there was a statistically significant difference in the changes in the leg GS only (p < .05). CONCLUSION: In the experimental group I, the arm and leg GS were statistically significantly reduced, but the balance ability was statistically significantly improved. The reason was that in the experimental group I, similar movements of the paralyzed arm were promoted due to the double-task exercise on the unstable surface, and sensory feedback and posture strategies were well utilized in the legs, which was found to be effective in reducing the GS and improving the balance ability. Therefore, based on these results, the double-task exercise on an unstable surface should 86 | J Korean Soc Phys Med Vol. 17, No. 1 be fully utilized for the rapid rehabilitation of stroke patients.

우크라이나 전쟁 이후 러시아와 중앙아시아의 관계 전망 : 지정학 이론과 크림전쟁(1853-1856)의 교훈을 중심으로

강정일 국가안보전략연구원 2023 국가안보와 전략 Vol.23 No.2

This paper examines Russia’s geopolitical moves expected after the Russia-Ukraine war. First, the lessons of the Crimean War (1853-1856), in which Russia attempted to expand geopolitically with the aim of “merging territories and maintaining sphere of influence” in the same Ukrainian region, were analyzed as three drivers of “fear, honor, and interest” proposed by Thucydides. Through this, we found an answer to the question of “What kind of driver and justification did Russia apply its expansion policy in the past and in which direction did Russia continue its geopolitical moves again after the Crimean War?” It also predicted Russia’s geopolitical expansion in the future from a realistic perspective by diagnosing the security situation before and after the Ukrainian War. As a result, Russia will attempt to expand geopolitically into Central Asia again as previous experience to secure a buffer zone from Western threats, protect national interests by maintaining political and economic influence, and restore its international status as a powerhouse. However, Russia’s geopolitical goal and justification in Central Asia is expected to be limited to increasing its influence on the countries and “re-incorporating them back into their own sphere of influence” rather than “territorial annexation.” 본 논문은 러시아-우크라이나 전쟁 이후 예상되는 러시아의 지정학적행보에 관해 고찰하였다. 먼저, 과거 러시아가 동일한 우크라이나 지역에서 지정학적 팽창을 시도했던 크림전쟁(1853-1856)의 교훈을 투키디데스가 제시한 ‘두려움, 명예, 이익’의 세 가지 동인으로 분석하였다. 이를 통해“과거 러시아는 어떠한 동인과 명분을 가지고 팽창정책을 적용하였고, 크림전쟁 이후, 어느 방향으로 다시금 러시아의 지정학적 행보를 이어갔는가?”에 대한 질문의 해답을 찾았다. 또한 우크라이나 전쟁 전후의 안보 상황을 진단함으로써 향후 러시아의 지정학적 팽창에 대해 현실주의적 관점에서 전망하였다. 그 결과 러시아는 세 가지 동인 즉, 서방의 위협으로부터완충지대를 확보하고, 정치⋅경제적 영향력 유지를 통해 국가이익을 보호하며, 과거 강대국으로서의 국제적 지위를 회복하기 위해 과거의 경험처럼또다시 중앙아시아로의 지정학적 팽창을 시도할 것으로 판단하였다. 그러나 러시아가 중앙아시아에 가지고 있는 지정학적 목표이자 명분은 ‘영토적병합’이 아닌, 해당 국가들에 대한 영향력을 제고시켜 ‘확고한 자국의 세력권으로 다시금 편입’시키는 것에 한정될 수밖에 없을 것으로 예상하였다.

The Effect of Neuromuscular Electrical Stimulation on Pulmonary Function, Gait Ability, and Quality of Life in Patients with Chronic Obstructive Pulmonary Disease

강정일,박준수,정대근 대한물리치료학회 2018 대한물리치료학회지 Vol.30 No.4

Purpose: This study aims to investigate the changes in pulmonary function, gait ability, and quality of life when NMES is applied along with CBE and to provide basic clinical data to be used in pulmonary rehabilitation guidelines for patients with COPD to treat patients with severe COPD. Methods: For this study, CBE and NMES of quadriceps femoris on both sides were applied to the experimental group (n=10), and only CBE was applied to the control group (n=10). For a pre-test, a 6-minute walk test was performed, and pulmonary function and healthrelated quality of life were measured. Moreover, an exercise program was applied to each group for 30 minutes per session, 5 times a week, for 6 weeks. After that, a post-test was conducted the same way as the pre-test. Results: In the within-group comparison, there were significant differences in forced expiratory volume in one second, 6-minute walk test and health-related quality of life between the experimental group and the control group (p<0.01)(p<0.05). In the between-group comparison, the experimental group showed an increase in forced expiratory volume in one second and 6-minute walk test (p<0.05) and showed a decline in health-related quality of life (p<0.05). Conclusion: The 6-weeks NMES program improved health-related quality in patients with severe COPD by increasing expiratory volume by reinforcing the function of quadriceps femoris. This finding implies that NMES could be an alternative mode for improving physical functions of patients with severe COPD, who cannot participate in a breathing exercise program or are reluctant to participate.
