국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

This study aimed to determine the effect of McKenzie lumbar support on pulmonary function in Stroke patients. Twenty subjects (n=20) were divided into two groups: a McKenzie lumbar support group (MLS group=10), a control group (n=10). Pulmonary function was performed to assess its effectiveness. A spirometer was used to measure the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF). The intervention was conducted for four weeks. In the MLS group, FEV1, FVC, and PEF were increased after McKenzie lumbar support. (p<0.05), while no significant differences in the variables were found in the control group (p>0.05). There were no significant differences in variables between the MLS group and the control group (p>0.05). Our findings suggest that applying Mckenzie lumbar support may be an alternative maneuver to improve pulmonary function in stroke patients.

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

This study aimed to determine the effect of depression between the healthrelated quality of life and pain in elderly persons with physical disabilities. A total of 111 patients who were treated at hospital B (Seoul, Daejeon, Daegu, Gwangju, and Busan) participated in the Survey. The SF-36 Health Assessment was used to determine the quality of life of subjects, the Korean version of the Geriatric Depression Scale-Short form to assess the level of depression, and Numeric Rating Scale to determine the level of pain. To determine the moderating effect of depression on the relationship between quality of life and pain, simple regression analysis, and the Sobel test were performed. There was a significant negative correlation between health-related quality of life and pain (r<-.3, p<.05), and a significant positive correlation between depression and pain (r=.251, p<.05). Thus, health-related quality of life had a simple regression relationship with depression and pain. Depression also showed a mediating effect between health-related quality of life and pain. The results of this study suggest that depression mediates between pain and quality of life.

국내 증권시장에서 외국인 채권투자의결정요인 분석

송원호 한국국제금융학회 2021 국제금융연구 Vol.11 No.2

본 연구는 2007년 – 2020년 동안 우리나라 증권시장에서 외국인 채권투자의 결정요인을 분석하였다. 본 연구는 다음 세 가지 측면에서 채권 자료의 이질성 (heterogeneity)을 고려한 점에서 기존 연구와 차별점이 있다. 첫째, 순매수를 분석하였던 기존 연구와는 달리 매수와 매도를 따로 구분하여 분석하였다. 분석결과 채권의 매수와 매도는 순매수에서 보이지 않는 이질적인 모습을 보여주었다. 둘째, 채권을 만기별로 구분하여 만기 1년 이하, 1년∼3년, 3년∼5년, 5년 이상 만기를 가진 채권을 따로 분석하였다. 분석 결과 만기에 따라 유의한 설명변수가 달랐다. 셋째, 마르코프-스위칭(Markov-switching) 모형을 사용하여 채권 투자 수준이 높은 국면과 투자 수준이 낮은 국면을 구분하였다. 분석 결과 국면에 따라 채권 투자는 서로 다른 결정요인을 가졌고, 경우에 따라 서로 다른 부호를 가지기도 하였다. 여러 다양한 설명변수 그룹들 중에서 글로벌 유동성 변수들이 가장 유의한 결과를 보였고, 그 다음으로 리스크 변수들이 유의했다. 개별 변수들 중에서는 VIX, MSCI한국비중, EMBI+, 대미환율 순으로 중요한 영향을 미쳤다. This paper analyzes the determinants of foreign investments in Korean bond market for the periods of 2007-2020. This study contributes to the literature in that it considers the heterogeneity of foreign investments data in three ways. Frist, previous studies analyzed net purchases of bond whereas this study distinguishes purchases and sales of bonds. Results show that purchases and sells of bonds behave quite differently from net purchases. Second, we distinguish bonds by maturity of less than one year, one to three years, three to five years and over five years. Results show that important determinants are different by maturity. Third, we define two regimes using the Markov- switching model by the amounts of investments. Results show that we have different determinants for each level and sometimes they have opposite signs. Among the variable groups considered, global liquidity variables are the most significant and risk variables follow. Individual variables are important in the order of VIX, Korean weight in MSCI, EMBI+, and Won/Dollar exchange rates among others.

A Study on the Effects of Silver Spike Point on Functional Constipation Improvement

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

The purpose of this study was to investigate the effects of the Silver Spike Point (SSP) on functional constipation. The subjects were 14 female students who attended a university located in Gyeonggi province and consent to participate in this study. The inclusion criteria were the fulfillment of two or more diagnostic criteria of Rome III or scoring four or more points in Constipation Assessment Scale (CAS). The CAS score was significantly decreased in the experimental group (from 14.29±1.38 to 6.86±2.91) (p<.05), however, there was no significant change in the control group (from 14.29±1.49 to 14.14±1.21). The present study suggests that SSP intervention is effective in mitigating constipation.

Muscle activity in relation to the changes in peripheral nerve conduction velocity in stroke patients: Focus on the dynamic neural mobilization technique

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

The objective of this study was to investigate the dynamic neural mobilization program on the changes in muscle activity and nerve conduction velocity (NVC) in stroke patients. The participants were sampled and randomly divided into experimental group I (n=12) who underwent arm neural mobilization and experimental group II (n=13) who underwent arm dynamic neural mobilization. As the pretest, peripheral NVC of the radial, median, and ulnar nerves were measured using the Viking Quest; the biceps brachii, brachioradialis, flexor carpi radialis, and extensor carpi radialis activities were measured with sEMG. Each intervention program consisted of 10 trials per set and three sets per session. The intervention programs were performed once daily for four weeks (four days/week). Posttest measurements were taken equally as the pretest measurements. Significant differences in peripheral NVC in all sections of the radial and median nerves and wristbelow elbow and below elbow-above elbow areas of the ulnar nerve, as well as in muscle activity of all muscles except the biceps brachii. These findings indicate that dynamic neural mobilization was effective in increasing peripheral NVC and altering the muscle activity.

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

The purpose of the study was to investigate the immediate effects of negative pressure soft tissue therapy on muscle tone, muscle stiffness and balance in patients with stroke. In total, 20 patients with stroke and assigned to the negative pressure soft tissue therapy group (NPST, n=10) or, placebo-negative pressure soft tissue therapy group(Placebo-NPST, n=10). Both groups underwent NPST or placebo-NPST once a day during the experimental period. MyotonPRO was used to assess the parameters for muscle tone and stiffness. Biorescue was used to assess the parameters for balance. Each group showed improvements in muscle tone, muscle stiffness, and balance ability (p<.05). Especially, Muscle tone, muscle stiffness, and anterior length in the limit of stability were the significant improvement on NPST group (p<.05). The results of the study suggest that the NPST is effective in improving muscle tone, muscle stiffness, and balance ability in patients with stroke.

Effects of Kinematic Taping Therapy on Dysmenorrhea

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

The present study aimed to investigate the effects of kinematic taping therapy on menstrual distress, pain, and prostaglandinF2α. The experimental subject was a 24 years old woman with the pain of over 5 points on the dysmenorrhea measurement test and no unusual reactions on the taping test. The menstrual distress was measured by the Menstrual Distress Questionnaire (MDQ), and the dysmenorrhea was measured by the Visual Analogue Scale (VAS) before and after the intervention. The prostaglandin F2α(PGF2α) was measured on the first day of menstruation before the intervention and 24 hours after the taping therapy by the blood test. The intervention of kinematic taping was conducted by the instructor of the International Kinematic Taping Academy, and the taping was applied to the lower abdomen and the waist. According to the difference of menstrual distress before and after the intervention, the menstrual distress turned out to be decreased to 96 points after the intervention from the 115 points before the intervention. The dysmenorrhea also reduced 3 points on the VAS from 7 points to 4 points before and after the intervention. The PGF2α decreased from 26pg/㎖ to 20pg/㎖ before and after the intervention. Besides, the PGF2α decreased from 26pg/㎖ to 20pg/㎖ before and after the intervention. Results suggest that kinematic taping therapy could be useful to reduce the menstrual distress, pain, and PGF2α.

Effect of upper thoracic mobilization on cervical alignment in stroke patients with forward head posture: A case study

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

The purpose of this study was to identify the effect of upper thoracic mobilization on cervical alignment in stroke patients with forward head posture. The subject's of this study were two stroke patients with forward head posture and a cervical curve angle (four-line Cobb's method; FLCM) less than 40°. The intervention, central posterior-anterior (PA) mobilization, was applied to the T1-T4 vertebrae (upper thoracic spine) following the Maitland concept. This mobilization was applied three times per week for four weeks. In the results, the cervical curve angle (FLCM) increased for both subject 1 and 2. However, Jochumsen method score was decreased in subject 1, while it was increased in subject 2. These results demonstrate that upper thoracic mobilization had the positive effect on the cervical curve angle but not on Jochumsen method score. These findings suggest that PA mobilization on the upper thoracic spine could correct cervical curve angle measured by FLMC in stroke patients with FHP.

The effect of stretching type on hamstring flexibility

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

The purpose of this study was to investigate whether static stretching or Thera-band stretching of hamstrings is more effective in improving the flexibility of hamstrings. A total of 40 participants performed stretching 3 times a week for 4 weeks, and a sitting trunk flexion meter was used to measure the flexibility of the hamstrings. Differences in hamstring flexibility before and after the application of static and Thera-band stretching were analyzed, and differences between the stretching methods were also analyzed. As a result, hamstring flexibility increased significantly after the static stretching program (p=.000), and also increased significantly after the Thera-band stretching program (p=.000). Although both programs were effective in improving hamstring flexibility, but there was no significant difference between the two groups (p=.058). Therefore, static stretching and Thera-band stretching are effective interventions to improve and maintain hamstring flexibility.

국제물리치료연구학회 국제물리치료연구학회 2018 Journal of International Academy of Physical Ther Vol.9 No.2

This study was conducted to examine the effects of the application of familycentered training over the 12-week period by the pediatric physiotherapist on functional balance and activities of daily living in children with cerebral palsy. Among the 26 children with cerebral palsy as the subjects were allocated to the experimental and control group. Both groups were subjected to neurodevelopmental treatment by the pediatric physiotherapist. The experimental group, participated in family-centered training program 3 times a week over a period of 12 weeks for the total of 36 sessions, functional balance and activities of daily living were verified through intergroup comparison. There was no significant difference between the outcomes prior to training and after 6 weeks of training, (p>.05) Pediatric Berg's Balance Scale(PBS) and Functional Independence Measure for children(Wee-FIM) increased significantly from those measures after 6 weeks to those after 12 weeks of training (p<.05). Therefore, these results suggest that on family-centered training on children with cerebral palsy has beneficial effects on functional movements and physical activities.
