Purpose
Preventing the effects of physical vulnerability is a practical approach to improving older adults’ depressive symptoms. This study aims to examine the relationship between gender differences related to muscle strength and depressive symptoms mediated by perceived stress.
Methods
In this cross-sectional study, data from 2,705 older adults (65 years old or older) from the Korea National Health and Nutrition Examination Survey VII 2016 and 2018 were analyzed. The moderated mediation model was developed; the outcome, independent, mediation, and moderated mediation variables in the literature-based research model were depressive symptoms, muscle strength, perceived stress, and gender, respectively.
Results
Perceived stress had a mediating effect on the relationship between muscle strength and depressive symptoms. The indirect effect of muscle strength on depressive symptoms mediated by perceived stress was β = -.02 (95% CI:-0.03~-0.01). The moderated mediation model demonstrated that the interaction term of handgrip strength and gender negatively affected perceived stress, which indicated that gender moderated the mediating model of perceived stress on the association of muscle strength and depressive symptoms (β = -.01, p <.05). The conditional indirect effect model was insignificant in the male group (β = -.00, 95% CI:-0.01~0.01) but significant in the female group (β = -.01, 95% CI: -0.02~0.00). Conclusions: Perceived stress mediated the relationship between muscle strength and depressive symptoms. However, the effect differed by gender. A stress-mediated depressive symptoms intervention program for older adults should be developed to consider women’s needs.

Abstract PDF: PURPOSE
The purpose of study was to test the effect of lower extremity muscle strengthening exercise using elastic resistance on balance on elderly women.
METHODS
Twenty four women who were over 65 years old were randomly assigned to either the experimental group that received the exercise programme (n=12) or to the control group (n=12) that continued normal activities except programme. Exercises included the following 7 different activities; chair squat, knee flection, extension, hip flection, extension, calf muscle raise, ankle dorsiflection. All the participants were subject to 3 tests, including One-Leg Standing Test, Functional Reaching Test, and Up & Go Test. The measurements were made before the excercise, 4 and 8 weeks after the exercise. The data were analyzed by using the two way repeated ANOVA.
RESULTS
The results were as follows; As compared with change of balance capacity between groups, a significant difference was shown in the up and go test (p<.05), but not in balance performance clinical test of OLST (p>.05) and FRT (p>.05).
CONCLUSION
The lower extremity muscle strengthening exercise using elastic resistance for the elderly women had some positive effects on the balance. Therefore this intervention can be broadly applied to other elders for preventing falls.

Abstract PDF: PURPOSE
To Perform a randomized comparative study investigating the effects of Pelvic Floor Muscle Exercise(PME) and Magnetic Stimulation Therapy(MST) and to identified the problems in each of PME & MST.
METHOD
Forty-nine patients with mild stress incontinence were randomly assigned to either of two treatment groups (24 patients in the PME group and 25 in the MST group). The PME group had a video exercising program for 40 times every day during 6 weeks. The MST group was treated with BioCon-2000TM, 2 times/week for six weeks. Pre-test and post-test were performed by Prineometer, 1-hour pad test. and Jackson's BFLUTS questionnaire of Jackson. Collected data were analysed using SAS 9.1 by frequency, Kolmogorov-Smirnov Z. Chi-Square-test, t-test, Fisher Exact probability test, Paired t-test, and Wilcoxon's rank sum test.
RESULTS
In comparison between before and after PME and MST, statistically significant difference was observed in maximal vaginal pressure, duration of vaginal contraction, amount of urine, and symptom of urination. In the comparison of the effectiveness between PME & MST, only the maximal of vaginal pressure (Z=2.58, p=.010) was significantly different.
CONCLUSION
The factor more effective in the MST group than in the PME group was high compliance.
