Effects of Muscle Strengthening Exercises Using a Thera Band on Lower Limb Function of Hemiplegic Stroke Patients: Sang Sook Han, Jeong Ja Her, Youn Jung Kim; Journal of Korean Academy of Nursing 2007;37(6):844-854. Published online March 28, 2017; DOI: https://doi.org/10.4040/jkan.2007.37.6.844

Abstract PDF: PURPOSE: This study was to verify the effect of muscle strengthening exercises using a Thera-Band on the lower limbs. METHODS: The design utilized for this study was a nonequivalent control group pretest-posttest design. A control group (16) and experimental group (16) were selected from stroke patients of K Oriental Medicine Hospital who were hospitalized for 5 months from December 2005 through April 2006. While only acupuncture therapy and physical therapy were used on the control group, acupuncture, physical therapy and additional muscle strengthening exercises using a red thera band were used on the experimental group. Muscle strengthening was performed 20 minutes per session, more than one session a day for 4 weeks. Hypotheses for this study were verified using Two-way repeated ANOVA and ANCOVA using a pre test score as a covariate. RESULTS: The experimental group with thera band muscle strengthening exercises showed a decrease in asymmetry weight loading percentage(F=14.704, P= .010), range of knee (Z=-3.15, P= .001) & deep tendon reflex score(Z=-2.52, P= .012) and moving performance(F=12.328, P= .001)compared to the control group. CONCLUSION: It is confirmed that muscle strengthening exercises using a Thera-Band can be used as an effective nursing intervention to improve the function of the lower limb of hemiplegic stroke patients.

The Effect of Treadmill Exercise on Ischemic Neuronal Injury in the Stroke Animal Model: Potentiation of Cerebral Vascular Integrity: Kyoung Ah Kang, Hohyun Seong, Han-Byeol Jin, Jongmin Park, Jongmin Lee, Jae-Yong Jeon, Youn Jung Kim; J Korean Acad Nurs 2011;41(2):197-203. Published online April 30, 2011; DOI: https://doi.org/10.4040/jkan.2011.41.2.197

Abstract PDF: Purpose
This study was done to identify whether pre-conditioning exercise has neuroprotective effects against cerebral ischemia, through enhance brain microvascular integrity.
Methods
Adult male Sprague-Dawley rats were randomly divided into four groups: 1) Normal (n=10); 2) Exercise (n=10); 3) Middle cerebral artery occlusion (MCAo), n=10); 4) Exercise+MCAo (n=10). Both exercise groups ran on a treadmill at a speed of 15 m/min, 30 min/day for 4 weeks, then, MCAo was performed for 90 min. Brain infarction was measured by Nissl staining. Examination of the remaining neuronal cell after MCAo, and microvascular protein expression on the motor cortex, showed the expression of Neuronal Nuclei (NeuN), Vascular endothelial growth factor (VEGF) & laminin.
Results
After 48 hr of MCAo, the infarct volume was significantly reduced in the Ex+MCAo group (15.6±2.7%) compared to the MCAo group (44.9±3.8%) (p<.05), and many neuronal cells were detected in the Ex+MCAo group (70.8±3.9%) compared to the MCAo group (43.4±5.1%) (p<.05). The immunoreactivity of laminin, as a marker of microvessels and Vascular endothelial growth factor (VEGF) were intensively increased in the Ex+MCAo group compared to the MCAo group.
Conclusion
These findings suggest that the neuroprotective effects of exercise pre-conditioning reduce ischemic brain injury through strengthening the microvascular integrity after cerebral ischemia.

Predicting Factors on Eating Behavior in Coronary Artery Disease Patients: Sang Sook Han, Ju Im Lee, Youn Jung Kim; Journal of Korean Academy of Nursing 2007;37(7):1193-1201. Published online December 31, 2007; DOI: https://doi.org/10.4040/jkan.2007.37.7.1193

Abstract PDF: Purpose
This study was aimed to identify the factors that influence eating behaviors in coronary artery disease patients and to create data for nursing which is thought to improve the eating behavior.
Method
The study population was coronary artery disease patients who were treated on an outpatient basis. The measurements were eating behavior, diet self-efficacy, perceived-benefits, perceived-seriousness, family support and medical team support. All of the measurement tools above were thoroughly modified to verify validity and reliability. Statistical analysis was done by the SPSS PC 12.0 program.
Results
The influencing factors for the eating behavior was diet self-efficacy (β=0.476), social support (β=0.253), chest pain (β=0.177), smoking (β=-0.173) and regular exercise (β=.169), which explained 46.2%.
Conclusion
Eating behaviors of coronary artery disease patients were influenced by diet self-efficacy, family support and the presence of chest pain. Therefore, the development of a program for efficient dietary education that prevents the progression of coronary artery disease is needed.
